Solenoid replacement: Pentax K-30 K-50 + K-500
(K-S1 Repairmanual you find HERE , K-S2 and K-70 are pretty similar to K30/50!)


Tools:
- 1x Precision soldering iron with pencil-tip (no butan-gas soldering-pen = too hot!)
- 1x Screwdriver JIS 000 or PH00 + PH000 (JIS is better, Pentax screws are JIS!)
- 1x Tweezers or precision pliers
- Headlamp is useful!
- Photos of all sides of K30/50/500


Preparation:

Print out the photos with the location of the screws, glue them on cardboard and drill 1.5 - 2mm holes where the screws are located. Thus you can place all of the screws into those holes because they are of different length:



Magnetize the tip of your screwdriver (there is no danger to the camera!) so the screws "stick"to the tip of the screwdriver. Make sure the body-cap covers the opening of the lens-mount for protection of the sensor etc.!

Take the battery out and open the pop-up flash.
Attention: Be careful that you don't charge the flash-condenser, you should anyway discharge it later on (or at least don't touch it) This black condenser is situated left to the AF/C/M- switch. The Plus (+) contact is to the front, minus (-)sits behind. The danger isn't in touching the Plus-contact but in touching the circuit-board above:

On the photo you see the
blue wire which carries the high voltage of the flash-condenser!


Discharge of the flash-condenser:

Best done with an old fashioned wolfram-filament ca. 60W light-bulb (or a 1 - 1,6 k ohms/10W resistor). A Light-bulb is better because you see the discharge! Solder some insulated wires directly onto the light bulb or on a lamp-socket and insulate any contacts! Have the other ends of the wires 0.5 cm bare (soldered). With one of those wire-ends you touch the metal K-bayonet (which is minus) and with the other end, you touch the front contact ofthe flash-condenser (Remember, this goes for the K30/50/500! For other Pentax DSLR make sure you identify which contacts are plus and minus!) The light bulb will illuminate until the condenser is discharged. The other option is to remove the battery and leave the camera without it for at least 48 hours. The condenser will discharge within that time. The photo shows how I discharge the condenser: I use measuring cables because I do it more often.




Sequence of opening the body: (Body-cap on the body!)

1. Remove all screws from the bottom part. Do not forget the long silver screw inside of the battery compartment! When the bottom-part is off, you can see one small screw next to the grey battery holder, it belongs to the frontpart. Take that one off as well and make sure you don’t forget this one later!



2. Remove all screws from the frontpart: (The small one on the bottom is already out!)

There are 3 screws on the left side (2 of them hidden underneath the rubber, this rubber you can remove completly):




Then there are 2 screws on the right (grip-) side, the upper one hidden as well, you just partly remove the rubber here so you get this one out:

3. Take all screws of the top part: 1 screw on each side where you fix the strap and 3 screws unterneath the pop-up-flash (which you opened without battery, remember!).
The K50/500 has only 2 screws here)

and then 2 screws on the backside behind the rubber-eyepiece:




You have to lift the top part slightly so it doesn't hold the front-part anymore. But don't lift it off completely! This lifting of about 1 cm is important because otherwise you will find it more difficult assembling the front part back into its position and adjusting the external part of the AF-S-C-M-switch to its internal counterpart!


Also you have much better access to the left pink wire on the solenoid. If you would lift the top part off completely you have to be very careful, there are critical wires and one flat ribbon wire which can easily get damaged.


4. Lift the front-part off.Have the AF-switch on position AF-S = upwards
but ..the inner counterpart opposite = downwards
and check this again before you later place the front part back into its position!
In almost every K-30/50 etc. repaired by myself I found that this inner part moves.
So this is crucial!



In AF-S position the screw-drive-mechanism pushes through that tiny hole in the bayonet to drive the AF of the lens! In C-position as well.
In M-position it moves back, so the lens is in manual position. Best to move the AF switch a few times to understand its function!

The AF-S-C/M-switch in AF-S-position:

You can clearly see, the screwdrive-mechanism extents out of the small hole!


Here the inner side of the external part of the AF-S C/M-switch:: The metal rod has to fit exactly onto the inner part of the switch! If you follow the steps as explained nothing to worry about!

below this rod you can see also this tiny ball which stops in those 3 different positions AF/C/M.
Make sure you don't lose it (it sits there pretty well jammed, so very unlikely to go lose)



Exchange of Solenoid:

Place the body on a soft tissue with the LCD-display downwards, the side of the grip facing towards yourself. Now you have a good view on to the solenoid itself
(and a headlamp would be useful!).



a) Unsolder the two wires (pink and lilac) off the solenoid. With the pliers, you hold the wire, then a short contact with the tip of the hot soldering iron. Not too long because you don't want to melt the PET plastic of the green solenoid nor later the PTFE of the white solenoid!

b) Unscrew the solenoid. The solenoid is fixed with a tiny screw on the right, left to it it sits on a plastic mandrel. It is fixed as well with red thread-locking-lacquer. On the bottom you can see the plunger which sits on the metal lever.
- With a very small flat screwdriver, you go behind the metal top part of the solenoid to get it loose.

- Then you grap it with tweezers on the top metal-body and tilt it forward and take the plunger off the lever it sits on.

- Don't touch the 2 coils, the copperwire is sensitive! You've got the green gremlin out. You can see very clearly one of the reasons it works bad: The two coils are not parallel but the plunger has to move within those 2 coils:





c) Now place a tiny amount of solder onto the ends of those two (pink and lilac) wires which have to be soldered back onto the pins of the new solenoid.

d) Built in the white solenoid. Place it first with the plunger onto the lever (green arrow) and make sure the solenoid sits on this plastic mandrel (small red arrow):



e) Carefully insert the tiny screw and tighten it:



You can add some thread-locking-lacquer as well or just use some nail-varnish. Solder the wires back on.
- Make sure each time you solder, you clean the tip of our soldering-iron first, you don't want to bring burned carbon residue into the melted solder.
- Make sure as well, that the solder really melts, don't just "glue" it, solder it! Solder has to "flow"!

- Make sure that the wires and particular the left pink wire are soldered onto the pins from the left side and not from the front. There is very little space for the wires as soon as the top-part is placed back on its place:


- Then check that the wires are tight. For this you hold the wire with tweezers and pull gently. It must hold well! (If necessary google how to solder)


- Now bring first the front-part back into position! Make sure you have the external part of the AF-S/M-switch on AF-S and the inner counterpart downwards so the screwdrive-mechanism is extended.

- Only then* push the top part of the camera back into its position and fix it with 2 of its screws!
*If you would start with the top-part as many show on their videos, you have to jam the frontpart in with the risk of badly squeezing the wires! You want to avoid this!

Function-Test: Close the flash! Put the battery into the battery-compartment, plug an AF lens onto the body, switch your Pentax on and take some pictures with a low aperture value (such as f2, 2,8, 3,5 or even lower depending on your lens). You can see the solenoid in action each time you take a photo.

Check again that the AF-S-C-M switch works!
(If not, the alignement wasn't done proberly, easy to fix now, you don't want to find out a bad alignment after you assembled the complete body!
Take the lens off, battery out and then open the pop-up flash again so you can screw the 3 (2 for the K50/500) screws there back in and continue with all the other screws. Don't forget the tiny screw next to the batterylever and the long screw inside the battery-compartment!




If it's the K50/500 you repair, take care as well with the rubberdoor which closes the USB-connector:





Part II:How to chose the right solenoid?

Several approaches have been tried, such as:

1. Exchange of the solenoid with the white colored "made in Japan" solenoid used in early DSLR bodies (the only real way!)

2. Exchange with the green colored "made in China" solenoid to be found cheaply on evilBay (Repeating error)

3. Sanding/filing the plunger of the existing solenoid not such a good idea

4. Soldering the plunger of the existing solenoid: very bad idea

5. Selecting solenoids from CD/DVD-ROM drives. very bad idea

1. This is after all the only long term satisfying method. All solenoids which were made in Japan have worked for long times and there were no reported issues that one of them ever failed. They were already used in old analog SLR bodies (with minor differences and sometimes opposite polarization) as well as in the earlier Pentax DSLR bodies such as:

*ist D, *ist DS (Samsung GX1), *ist DS2(Samsung GX1s), K100D, K110D, K200D, K-m (2000), K-x, K-r (all those have 2 solenoids built in: One in the aperture circuit, one in the flash circuit).

The made in Japan solenoid was also used in the K10D (Samsung GX10) and K20D(Samsung GX20).
High shutter count was achieved with them and never any reported solenoid failure. Those were then the cream-of-the-crop!


The body of the green made in China solenoid is made out of PET. The white made in Japan solenoid uses PTFE (Teflon), a superior and much longer lasting material. The green solenoid was first sometimes applied in the flash compartment of some (not all!) Pentax K100D, K110D, K200D, K-m, K-x and K-r (it seems mostly Europe). The first body with the green solenoid used in the aperture-circuit was the Pentax K30. It was the K30, followed by the K50 and K500 which stirred up users because of pictures almost completely dark i.e. underexposed: The reason was the plunger of the solenoid remaining stuck to the hold of the permanent magnet which sits in the small long sleeve on top of the two coils. Those 2 coils act as an electromagnet, producing an opposing magnetic field to the existing magnetic field of the permanent magnet. When this magnetic field in annulled, the plunger moves out according to the readings of a small sensor reading the applied aperture. There is a defined holding force of the permanent magnet in relation of how much the plunger can be magnetized.

It has been measured, that the holding force of the "green made in China solenoid" is larger than the holding force of the white "made in Japan" solenoid. This is also very easy to just "sense" when one pulls the plunger out of the body of the white solenoid compared with the green solenoid. The difference is pretty obvious. You need much more force for the plunger of the green solenoid.


There is a tiny difference hardly noticeable between the older solenoids used in the analog Pentax SLR bodies and those out of the early DSLR bodies:
The earlier analog SLR versions release that tiny bit quicker (even less holding force) but also they sit with a minimal tilt when built in into a Pentax DSLR and thus the plunger sits slightly tilted on the aperture-control-mechanism:




Compared to this 100% accurate straight line of a 'DSLR white made in Japan solenoid':



I myself and a few others in Europe also came across opposite polarized solenoids in the MZ-Series. This is very easy to check: The left contact (solenoid in K30 aperture mechanism!) pink wire is plus (+),the right contact (lilac) is minus (-). Solder long wires onto the pins, connect them for a short moment to a 3V battery: If the plunger can be pulled out without almost zero resistance: Polarity is correct. If the plunger sits even tighter: Opposite polarization. But even then they can be used but one has either to change the wires in the Pentax or adding length to the pink left wire so it can be soldered to the right side.

I have found correct polarized solenoids on MZ50 and MZ7 "made in Japan", but opposite polarized solenoids in those assembled in Philippines. It seems most MZ-Series Pentax' sold to Europe were assembled in the Philippines. I have not invested further because the solenoid from the early DSLR bodies anyway is better. The price for a damaged *ist or K100D is pretty much the same as for a MZ-series. So why bother!
Using the DSLR "made in Japan white solenoid" is the only save way to allow the aperture mechanism not to fail again!

2: It is obvious that this method by using the same faulty solenoid again is prone to fail again. Nothing more needs to be said about this method. It would be rather silly to take on all this work of disassembling your K30, 50 etc but only do it half hearted and cheap. Repetition of the same problem.

This brings us to
3: Sanding, filing even grinding the plunger. This method was invented in Russia and promised a cheap and safe way to go. It is applied by some repair-shops, but there have been reported problems! A camera is a precision instrument and the sanding / filing solution introduces more problems than it fixes.

To achieve a similar holding force such as the white made in Japan solenoid guarantees this method changes the movement of the plunger in the already cheaper and easier to be worn out PET body of the green solenoid. A tilted plunger can eventually lead to a complete blockade of the mechanism: See the next photos of how tilted the plunger of the green solenoid sits compared to the straightness of the white made in Japan solenoid:




The mechanism which the solenoid brings into action is itself quite complicated and demands the solenoid to work very precise:




With sanding the plunger quite often the wheels get stuck or get de-arranged.
The plunger tilts even more:




If a sanded solenoid does more damage, you need to replace the complete socalled diaphragm-control-block : A very complicated undertaking! Changing the solenoid is almost peanuts compared to this work. It takes hours and one needs to know a lot to take this on! An almost complete disassembly of the camera!

In March 2017 I took those photos to show the difference between the green and white solenoid:





One can clearly see that the plunger of the green solenoid has more "play" to all sides, i.e. it will already move with less guidance. The body with the 2 coils acts as a kind of bearing. The plunger moves in and out of this bearing. With more play there is more danger of tilt which is enhanced when filing/grinding the plunger.
Also very clearly visible: Corrosion on the plunger. The material of the green "made in China" solenoid is not of the same quality as the material used with the white solenoid. If there is corrosion where the plunger sits on the lever, there will be as much corrosion on the parts which are filed/sanded!

I came across a few K30's with "sanded plungers". And on a few I did notice corrosion when grinding was applied.

4: This method of applying solder to the plunger and file excess solder away is not to be recommended at all. Very bad idea!
The idea itself is similar as in method #3, i.e. to bring the plunger that amount away from the magnetic field of the permanent magnet and thus decrease the holding force. But this will push the plunger further downwards, its position on the aperture control mechanism is wrong! Again this can lead to further failure. Most likely even quicker. I never tried it because logically it made no sense.

There is another method I have tried, decreasing the size of the magnet. I have tried it a few times, it never worked out, either the problem remained the same or the opposite was achieved, the holding force was not enough. I also tried exchanging magnets: No luck either: Failure.

5: Beware of solenoids from DVD-ROM and CD-ROM Drives! They are usually blue colored and are made in China as well. They have usually another impedance (often 15 ohms) which can lead to damage on the main-board of your Pentax as well as dead coils.I have come across one single solenoid from a Sony walkman: Not quite the sameas in the Pentax DSLR and too strong holding force either.

Also forget other solenoids such as from Korea (Moatech): They will not work:

Lens Spanners -- Using the right tool for the job

Lens Spanners – Using the right tool for the job


Introduction

Like other repair jobs, fixing cameras and lenses requires proper tools. The lens spanner wrench, or spanner for short, is an essential specialized tool that is used to remove lens retaining rings and collars, small caps and covers, and screws with special heads.

Disassembling and refitting the components should be done carefully to avoid damage. Although make-shift spanners are feasible and may seem to be cost-effective for an occasional job, using a proper tool increases the likelihood of success and reduces the risk of inadvertent damage. In hindsight, I am glad that I invested in several spanners, which have served well in my successful repair efforts.

A search on the internet will reveal plenty of questions and discussions concerning lens spanners. This article is intended to provide some insight as well as an overview of my experience with several types.


General Features and Characteristics

The spanners in my toolkit are shown in the figure below.





Lens spanners are available commercially in various designs, prices, and qualities. An ideal spanner would have the following characteristics:
  • Positive fit. The tip must fit securely in the component’s holes or slots, with little or no wiggle. This requires the tips to be properly sized for the job, while the shafts near the tips should be parallel to each other.

  • Free of play when tightened. The tool’s arms and the tips should not wiggle or move after the tool is tightened for use.

  • Ease of use. The tool should offer easy, smooth, and precise adjustment; an assured hand grip; no shift in tip positions while tightening; and no flex when torqued.

  • Range of span. The span should adjust from several millimetres to around 100 mm. This may not be possible in a single tool, so the user may need to acquire more than one.

  • Selection of tips. To facilitate various jobs, the spanner should accommodate several different tips, including points, flats, and half-flat. Similarly, some jobs may require a spanner with a long reach, so it’s desirable to have various tip lengths.

  • Custom tips. Certain jobs may require special tips, which the handy repair person may fabricate at home. The spanner should accommodate such tips securely and precisely.


V-style

My V-style spanner is a model from Japan Hobby Tool, which I bought for approximately CAD $40.00 from Amazon. It’s also available from Micro-Tools.

The two legs, each 140 mm long, are formed from plated channeled steel and attached securely at one end by a flanged pin. The key feature of this tool is the threaded locking rod and its four nuts – this configuration provides for the desired span to be set precisely and locked securely in place. This spanner is easy to adjust and it’s rigid when tightened. It also allows a fair torque to be applied safely to a tight workpiece. The two standard tips include a point (0.5 mm) and a flat (5 mm). It meets most of the key characteristics noted above.

Its span range of 12 – 60 mm works for most jobs. A 3-mm span may be attained by using the offset tips from one of my other spanners. The included tips are relatively short, which precludes their reach into deep spaces. Luckily, the shaft holes are 5 mm diameter, which accommodates tips from another spanner for extended reach.

Because of its ease of use, secure setting, and rigid build, this is my preferred spanner.


Twin-rod Style

One of the commonly available spanners is the twin-rod, twin-arm type. This type is available from various suppliers, and its cost runs in the CAD $ 25.00 range.

The arms are 100 mm long and 10 mm in diameter. It is secured by tightening two thumb screws on each arm and a separate screw for each tip. The span range is 2 – 80 mm. My tool came with several useful tips: an offset point, a 5-mm flat, and a 2.5-mm half-flat.

While this particular spanner is fairly versatile with its various tips and useful span, I find that it’s somewhat frustrating to use. Unless the arms are kept perfectly perpendicular to the rods, they often snag when being adjusted. Furthermore, the arms are difficult to adjust and set precisely, as they move slightly when being tightened. When working at close quarters, such as removing a retaining ring for a convex lens element with little clearance, one must use this tool with particular care to prevent scratches. When the arms are properly set and tightened, though, this tool is reasonably secure and affords a fair torque.


Bar Spanner

Another common spanner features a single stainless steel bar and two arms. This type of tool is relatively simple and can be acquired for around CAD $15-20.00.

With a span range of 8 – 130 mm, this style is useful for wider retaining rings, although I’ve never encountered such wide pieces. When adjusting the span, the arms slide loosely across the bar without snagging. However, the cross section of the bar and the slots in the arms are not matched precisely, so there is an excessive amount of lateral play (2 mm) at each tip even when the arms have been tightened. I have mitigated this play somewhat by replacing one of the thumb screws with an included socket-head cap screw to securely set one of the arms, while retaining the other thumb screw for convenience. Even so, the second arm is prone to movement when set.

Another disadvantage of this spanner is that it does not accommodate other tips – what you see is what you get with a 0.5-mm point and a 3-mm flat.


Other Styles

Other styles or models of spanners are available from various suppliers. I’ll mention two that I’m aware of, but because I haven’t used either, I can’t vouch personally for their quality.

ThorlabsSPW801 Adjustable Spanner Wrench seems to be a solid precision tool, albeit more expensive than most other options at around USD $ 105 or CAD $ 140 (as of March 2020; shipping extra). Featuring a spanning range of 3 – 73 mm, the tool has reversible flat and pointed tips. Users report that it is well made, solid, secure, and easily adjusted. One user has mentioned that the tips can wobble slightly when adjusting the span. Spanner Wrenches

SK Grimes New Design Adjustable Optical Spanner Wrench is a robust version of the bar spanner. The span ranges from near zero to 140 mm, and pointed and flat tip styles are available. It appears to be a hefty tool, affording a solid grip and precise adjustment. USD $ 56 for either set of tips or $ 97 for both (as of March 2020; shipping extra). Spanner Wrenches SKGrimes


Home-made Spanners

As illustrated in a Pentax Forums article (https://www.pentaxforums.com/forums/114-maintenance-repair-articles/199396-s...bstitutes.html) there are many possibilities for home-made spanners by re-purposing common workshop items:
  • Vernier callipers

  • Needle-nose pliers

  • Scissors

  • Marking or measuring dividers

  • Pins held in locking pliers

  • Nails through a piece of wood

While any of these make-shift tools might work for some jobs, my opinion is that their use depends on luck that they won’t slip and scratch a lens element or mar a visible metal component. In particular, any non-locking tool such as scissors or pliers cannot be controlled with assurance. Furthermore, some of the tools do not have parallel arms, so the tips will not fit positively or securely in the workpiece.

I hope that you have found this article to be useful.

I've been processing/re-processing stuff from last year. For part of the summer I had this little fella visit the field next to my yard, and after I saw him a couple times I began leaving little treats for him. There was also a fox or two around, so sometimes I'd leave a snack for one, wait a little while, and then the other :lol:


On a dreary and drizzly afternoon, Pentax K 500/4.5 @ 5.6. Cropped away about 2/3 of the frame.

I had to get close to get the images I wanted and then had the humorous experience of listening to all the shutters from people with their big fat lenses going off behind me, from much further away. I was looking at at least $15000 of gear taking images that weren't as good as mine because usually further away means not as good.

A processed stack of the Great Orion Nebula and Running Man from the same session last week where I posted the first, throwaway, shot.
This is the best 123 of 205 images stacked and processed to my ability to bring out the detail. Each shot was 20 seconds using astrotracer:


Lens: SMC A* 400mm f/2.8
Camera: K-3
ISO: 1600
f-stop: 3.5
Shutter: 20s with astrotracer
