Should I expect solenoid failure on a K-50

Not only users with non-failed cameras but as much users with cameras that failed.

It was different in the German pentaxians-forum.
Because it is a "German-language-only" forum and Pentax in Germany, Austria and Switzerland has a very small market-share, this forum has

what could be called very loyal and very interested members.
Loyal (similar to here) also in respect that members very quickly get very upset if anybody questions something about their brand.
There is another very well know forum, the DSLR-Forum, but for all brands. Pentax is bashed there on a regular basis so that Pentaxians

retreated to the Pentax-only forum.
So when the poll started, all those who had no problems for sure voted!
The information of the poll went to all members!


I think the time for another poll is gone. The K30 and K50.... although still good cameras... are nowhere in focus as it used to be.
Not even the great K-S1 or K-S2 anymore, although they can deliver in their way as well as the K-70.


The K-70 is of interest and new K70's won't suffer anymore from that problem.
I think the class action lawsuit filed May 2020 and reports here on the forum got Ricoh moving to do the 2.nd modification
and they finally got it. They could have "got it" much much earlier on, it would have been easy.

75 bucks worth? -> Pentax SMC DA 50mm f/1.8 K-mount with uv filter'

The DA50/1,8 is more expensive in the EU, outside the EU but Europe even more so (new or used)

So comparing US prices isn't useful.
Right now from Ricoh EU, Amazon.de and Amazon France it is € 179 new and € 120 used (but selected) from Amazon warehouse-dealers (so with the right to return). (DA35/2,4 is € 195,51!) Cheaper on Amazon UK but the you pay VAT + custom-handling fees + high shippingcosts. Since Brexit

if you purchase anything on ebay UK from outside UK, you pay right away those costs. Not worth it anymore. Particular if something goes wrong and you have to send it back, you'll have a hard struggle to get VAT back, worse handling fees are lost then.

The DA18-55 zoom you already have is nothing special at all, if not the MKII Version or the DA-L or WR. The early version with came with the K10D is really outdated.

But you can use it to find out with focal length is better suited to your needs.
18mm is good for landscape and if you need wider, then a good sample of a DA 16-45/f4,0 ED is worth considering.
It is far superior to any kitlens but you must check that it doesn't wobble too much.
It does wobble anyway due to its construction but pictures should be evenly sharp throughout the periphery, if one side is less sharp then send it back!
A focal length of 35mm is as others said the equivalent of 50mm on fullframe or a analog filmcamera, the DA35/2,4 is a very good and cheap lens.
But the DA50/1,8 is faster, i.e. you can take photos in lowlight situations the DA35 with a few stops less (2,4) can't.
And as Christian said, the F50/1,7 is quite a bit better except maybe bokeh, because the DA50/1,8 has 7 rounded blades, the F50/1,7 has 6 blades and not rounded! I personally would not care much about this difference.


Of course you won't have the benefit of a fast lens with the DA16-45/4 but it is f4 throughout and it can 1:4 macro at 45mm
But it is sharp wide open (at least my sample which is one of the few zooms I use)
From 20-40mm it is almost as good as the DA20-40/2,8 ltd which of course is much better manufactured.

I had a long conversation with one of the best engineers repairing Pentax-lenses in the USA. He knew the FA31ltd inside out, as well as the legendary K28/2 (a Zeiss-design). He told me that the DA16-45 is a floated design like the others, something quite difficult to achieve with a Zoom
and that this lens was a real masterpiece. Then I got 2 samples of it, one was NOS (new old stock) and I love it. I kept one sample, the other is used by one of my sons.

The only lens which I feel is as good but with a wider range and faster is the Sigma 17-70/2,8-4 DC Macro HSM Contemporary, a very good lens but expensive (and more weight)


Buying from dealers over Amazon or ebay is not really risky because you can send it back (by law) within 14 days.
But you have to pay the shippingcosts, this has changed within the EU.

This is not quite true, it was only the first badge of the K70 which I explained in all detail HERE

So @mikesbike got it more precise:

Or:

Some quite good Pentax photographers even prefer the K-70 over the KP. I have the KP and like it very much but I need it's performance for handheld lowlight, there it has an advantage over the K70 (AF as well, but I would be fine with the AF of the K-S1/2 and K-70).

But I think the TO got a good deal of answers, sometimes I feel a newcomer is kind of drowned with "good will hunting"....:o

I am pretty sure that was the reasoning put forward when the APSC lenses were first introduced. Canon EF-S in 2003 IIRC.[/QUOTE]
The SMC Pentax DA 16-45/f4,0 was introduced as well in 2003, the DA14 in 2004.
None of them seem to an attempt to make cheaper lenses.
Knowing a little bit of the story behind the DA16-45 it was quite a special lens.

And that makes the difference: You have had a K200D but you don't have it anymore (possibly for a long time)
Due to maybe aging components all those Pentax-bodies:
*ist-D/S/DL, K100D, K110D and K200D can develope battery issues.

Sometimes it is just the tension of the contacts (and of course corrosion if leaky batteries)
which can be simply solved

But not if components have aged and one even gets short use out of brandnew NIMH Eneloop Pro's
(no other NiMH's than Eneloop or copies like Ikea Ladda's should be used anyway, Pentax went away from Energizer NIMH's!)

Then only Lithiums will work and they do work!


I have researched this quite a bit because I have rescued quite a few of all those I have mentioned!
But I could not detect which part on the mainboard or other ages. Nor one of the most splended engineers I have had at hand.

An argument I fully understand. One of my sons now travels the world with his girlfriend for at least 1 year. Hitherto he had a Pentax K5II with several lenses, but for this trip it was too heavy. They went for a Sony Alpha 6400 and are very happy with it.



It is a nice lens, but when the SDM is gone, only manual focus. A pitty, I know but repair is expensive.



Particular the K200D is prone to this problem, I have one even with a very low shuttercount but it won't work with Eneloop Pro's nor any others but it works perfectly well with the Energizer Lithium Ultimate AA's as mentioned. The backup CMOS is alright, so that cannot be the source (Some guessed this could be but I daubt it). I had this problem with several K200D's so it isn't helpfull if others claim that this problem doesn't exist with their K200D, I have disassembled quite a few of them and know it almost inside-out.


But what helps is to check the contacts. Not so much for being clean (which is obligatory and a problem if a battery leaked and destroyed the surface) but for tension: Often just a tiny bending upwards and there is enough tension there again and everything is alright.

All pre K-m bodies had no possibility to change batterytype in the menu, that came with the K-m until the K-r.


Enough of that....



Yes, of course all K-lenses as well as M42 lenses via an adapter

Not to forget the K-S2 which is quite similar and the K-S1. Both have the same great sensor and are almost as good, some would say they
are even better due to the rare sensor used there. I have the KP but use the K-S1 for travel (before it was the K-01 which I can't recommend anymore)


But: If I'd buy a K70 I would get a new one with warranty. This is because early K70's sometimes had the ABF problem, i.e. a tiny part

named solenoid could go wrong. This was solved with the latest Pentax K70's!


If you buy a K-S2 or K-S1 then look out for those which are offered with the "Japan-Solenoid" (on Amazon.de that is possible)
Then you are save and you have with either of them a fantastic camera, the K-S2 being a little bit more comfortable with free LCD-Movement
and better low-light performance, the K-S1 being the smallest DSLR ever without real compromise (there are smaller Canon's but not with that quality!)



Nothing too special, with the K70 particular you'll see the limitations. Worst the 28-300... one can't cheap physics.


A very good lens!



One of the few zooms I use! Great value. Highly rated.



excellent, small and light



Not so special.*

Another lens if you need 300mm at the long end is of course the

DA55-300PLM!!!
A fantastic lens, super fast, I sold my Tamron 70-200/2,8 DI LD Macro for it, never any regrets.


So your existing lenses have 1 gem, the Tamron 90/macro.
The others you mentioned nothing to squeeze the quality out of a K-S1/2/70!


If size and weight are important, you might just sell what you have and get something that is best suited.

Or solve the K200D and then keep what suits best and get a lightweigth something anyway.

*I don't have the F28/2,8 but the A28/2,8 and I had the M-Version, both have the same optics.
I had once the K28/2 (Zeiss designed), could sell it for very good money long time ago for the FA31ltd.
But I also have the K28/3,5 which is not fast...but a fantastic lens.
I have now read the reviews of the F28/2,8 and some claim that it is better than the A-version, maybe they got special samples.
So maybe I was too hard on this lens.

That's why I wrote:




That's why I wrote:



I fully agree.

And yet there are a few different figures which show interesting numbers:
- seller Potmano sold 680 White Japan-DSLR-Solenoids on ebay.com

- Chinese sellers who give numbers sold 720 cheap and very bad Lenovo China-solenoids*
- I myself repaired about 120 Pentax DSLR's with the Japan-DSLR solenoid and I know of many who did so after I tought them.

That makes ca. 1500** who took on the DIY repair... and we know there will be many more.

Remember: DIY repair, i.e. not those repaired by all the official repair-shops!
So I think all those (remarkeable) figures do have some weight.
*Today I could count ca. 50 ebay sellers offering those cheap Lenovo-Solenoids (and only 40% give numbers how many they sold)

There is another huge quantity on Aliexpress and an even larger quantity on Alibaba... that is for large numbers/vendors

** and of course those 720 with the wrong Lenovo-Solenoid will go wrong again, which might disturb numbers
and some might buy the same rubbish again....

I still like the K200D very much. It is sensitive to batteries but not so with Energizer Lithium Ultra AA's.

But yes, it is quite large and heavy, also less with the Energizer Lithiums!


Concerning weight:

If you can find a used K-x with low shuttercount, this one is light enough, takes the same Energizers and all your lenses.
Otherwise the K-S1. Lighter with a DSLR will not be possible.

Light and good lenses are:
- DA50/1,8
- DA35/2,4
- SMC Pentax A50/2,8 macro (manual focusing, but a fantastic lens)
- DA40/2,8 limited
- DA40/2,8 XS (the lightest of all of them)
- DA18-50 (not the DA-L version!) as a zoom
- DA20-40limited (an expensive masterpiece)


Concerning the DA17-70SDM: It was SDM only, i.e. one couldn't convert it to screwdrive. The old SDM motor of those lenses often made problems and then only manual focusing is the solution.

The only option I see then is to send it off to PC35 Photolab.
As this person seems to give (unofficial) Lifetime warranty to his repairs (he does the filing job) and the price is $ 100 + shipping I think
this could be a way to go.
I myself am not a fan of the sanding method and explained in all detail here:
https://www.pentaxforums.com/forums/151-pentax-k-30-k-50/388728-why-you-shou...solenoids.html
I don't know if any of the official repairshops (which would be Precision) would install the latest modification of the China-solenoid.
We had this discussion recently.


Of course if a forummember would offer to do the repair, that would be the best.

If one would buy the Japan solenoid on ebay plus a sensible fee like $ 100 you'd be off best.

The side of the screw is not really important because it just defines a difference of the socalled "diaphragm-control-unit"!
That is the block which was introduced as pictured with the K-30.

As soon as ABF became known, many Pentax repairshops replaced the complete unit which of course was pretty useless because it was only the solenoid which failed.

So I won't go into deep explanation but just to make sure: The side of the screw is totally unimportant!
More information is not needed.

Odd yes, but I observed something that could explain it:
A German dealer sold really large quantities of K50's and later K-S1's as new but ex-demonstration units allegedly from Pentax-shows!
I got a few of those onto my work-bench. It had turned out that they were repaired, i.e. solenoid replaced!

I don't think any were from shows but just got their solenoids replaced either for security or because they already had developed ABF.


Even a brandnew never used Pentax with the wrong solenoid can develop ABF!
I had a few with very low shuttercount, the lowest as far as I can remember was 6.

But you know what is more odd:

The magnet of your China-Solenoid seem inbetween 1st and 2nd modification.
If you look closely at the picture I have in my main post, the magnet of the 3-rd generation solenoid is shorter, their is an (air-) gap at the top as well! If you'd move this magnet upwards, its lower end would be almost at the center of the two holes!

That's right, there was the

1.st modification December 2015
2.nd modification with the K70 possibly around 2020 but nobody knows for sure.

It was December 2018 when the main representative from Ricoh Paris/France wrote to me, that "a new solenoid was used in the K-70".
We were in contact because a few K70's developed ABF and members of the German/Suisse forum got worried.
This was then the 12/2015 (1.st.generation) modification.

Another tiny difference was, that in the K70 the screw fixing the solenoid to the controlunit itself is located on the left side (no real difference of course).

@Stevebrot started a report in 10/2018 until 12/2019:
K-70 Underexposed Photo Reports - PentaxForums.com
If you read #149, this was dedicated towards me myself.

Attemps to distract away from the solenoid being the culprit sometimes went very curious/funny ways:

Some repairshops invented a so-called resistor-chip which would fail. Too much voltage would pass now through the solenoid which in turn would go bad.

This was really the funniest invention because there exists no resistor-chip in any Pentax-circuit driving the solenoid, there are resistors, yes, and there is a diode which protects (but none of those ever went damaged!). Of course one could call a diode a resistor because "it resists" into one direction and allows the voltage into the other.

Today I have a K70 on my workbench, manufactured 6/2017.
The solenoid in there: 2-nd generation, i.e. 1.st modification (clearly to be seen on the attached photo)
Low shuttercount, typical failure.

The E-Dial of the K-m, K-x and K-r are all three the same. The most reported issues were with the K-x E-dial, for which I wrote a tutorial:
Tutorial E-Dial (Thumbwheel) Repair Pentax K-r, K-x and K-m (K2000) - PentaxForums.com

Front-focus with tungsten (wolfram) -light! This wasn't solved with firmware.
But with LiveView this problem won't come up!

Another issue can be colours, particular orange. But here one has to set AWB/tungsten-setting from Auto to a higher setting, then it works perfect.

But not to forget, reviews were done in 2011, now tungsten is hardly used anymore.
But if one does stage-photos, one has to experiment with AWB!


The coloured versions suffer much quicker from use than the black versions. Particular if the rubber is white or grey (K-S1's can suffer badly there):
The rubber takes on dirt and sweat much quicker, worse of nikotin.
I have a K-x and a K-r here, my wife loves the K-S1 due to small hands and short fingers. But she can hold the K-r better than the K-x.


A split-image focusing screen needs carefull shimming in the K-x, the cheap Chinese-versions even more so.


If it would be mounted the wrong way then only because you'd had to take the nose/tap because it would be on the wrong side (which happened quite often with the China versions)
They even don't know about the size difference, claim it would work for Pentax DSLRs which is impossible:

Useful to know:

How many solenoids has one changed, how many Pentax DLSR for that reason disassembled?
And how many checked for manufacturing date?

Nevertheless:
It is possible that at the assembly-place workes took an early production solenoid.
If one takes into account how very badly workers there are paid, one shouln'd be surprised if not everything goes "by plan"

What really counts
1. "Holding force" and this can either be measured or "sensed" if you know how-to. If you don't have sensitivity in your fingers,
you are more or less similar unsensititive to good food because your sensitivity is measure by McDonalds or similar deep frozen hamburgers, hot-dots and/or similar junk-food,
so no much value... and I won't bring in good wine or .... a good eye

2. The quality of the alloy, almost impossible for us to "measure"

All this is quite unimportant:
We know that the white DSLR Japan Solenoid never failed... I have measured its qualities and that is all we need to know!

The difference in results is logical and pretty obvious:

The German Pentaxians Survey started 2/2016 and went with 95% of all votes unit 12/2018 so we have a survey of almost 3 years!


The survey here in the Pentaxforum went for about 3 month and was ONLY in the year 2016:
Is started 7/2016 and ended approx. 9/2016, the final result was published [url=https://www.pentaxforums.com/articles/photo-articles/pentax-aperture-block-failure-survey-results.html]9/2016]
So we have a very short period of about


3 month versus 34 month!

My own observations show very clearly, that my guess that over 50% of all K-30 failed and almost 50% of all K50's and K500's (all K500's worldwide were manufactured before 12/2015!) is pretty relalistic.

And I would add that it hit over 50% of all K-S1's!
Just that K-S1's were purchased often by youngsters who ... when contronted with ABF in most cases will just be pissed off and chuck the "bloody thing"... I am not exaggerating but this is based on what I observed.... 95% of all K-S1's were manufactured before 12/2015, I never ever had a K-S1 manufactored after that date in my hands... and I had many.

So I will add at least 30% of all K-S2's because most K-S2's were manufactured before 12/2015 as well.

All this changed very positivly with the K-70, there were only a very few early K-70's which failed
and Ricoh very quickly "got it" and did the right mods and solved it.


As the K-70 is very popular, sold "like hotcakes" as well as did the K-30...

and.... the K-70 is much longer on the market... this is really good news because I haven't heard of any K70 fail for a long time.

There was a survey on the German Pentaxians-Forum for the K-70 as well:
44 no fault (but actually one later got it)
14 had ABF (11 with their 1st K70, 3 with their 2-nd)

This means 24% of those early-manufactured K70's failed and developed ABF.
Almost all votes from 7/2017 until 3/2019 (one last entry in 2022 but the K70 was an early one!)
This means from 3/2019 no more entries.

Actually there were 2 further K70's from a member there. He didn't vote but sent them to me for repair.
That would make it 26%.
Both manufactured in 2017.
He sent me

2 x K70
3 x K30
2 x K-S1 for repair!

All of them ABF but... he never lost trust into Pentax, he loves them and never ever had grudges.

Just make sure you use your Pentax DSLR regularely. You have warranty on the repair so if it goes wrong again, maybe in Australia you have there as well that generous warranty Australians have anyway.

As I have answered here:

this isn't really the case at all!
In most cases of ABF with the K30/50/500 the AA-adapter and using Eneloops or similar only helped for a short time.
As soon as the solenoid start to be stuck, that's it! Nothing can be done exept either change against the Japan DSLR solenoid
or cheap modifications (which can lead to other problems)

If that would really be the reason, then ALL Pentax DSLR's using a solenoid would be prone to this fault as well.

But this isn't the case!


NONE Pentax (and Samsung equivalents) DSLR prior the K30 (and using the white Japan solenoid for aperture-control) ever failed!

This were:
*ist-D, *istDS, *istDS2, Samsung GX1, Samsung GX2
K10D, K20D, Samsung GX10, GX20
K100D, K110D, K200D, K-m, K-x, K-r

Also since the 3-rd generation China-Solenoid used in the K-70 (the 2-nd generation was only used a short time)
we have no more failures!

So as you call it "kick" from the battery helped for a short time if ABF appeared if the AA-Adapter D-BH109 was used with Eneloops in particular.
But in almost all cases this helped just for a short time because the reason why the plunger of the solenoid stuck was not because of lack of "kick"

but because of a yet too strong holding force which was finally solved with the 3-rd generation China solenoid and possibly a different alloy used for the plunger.


It was us here in this forum who solved the problem and led the Ricoh engineers to the solution, who were groping in the dark for unknow reasons
and tried to solve the problem for quite a long time without real success.


Of course Ricoh could not retreat to the original Japan solenoid because the manufacturer, Shinmei Japan, had moved production (and all machines) from Japan to China for final and thus the only solution was to modify the existing solenoid.

If Ricoh would have trusted the findings here in the forum and taken on measurements of their own (which would have been much easier for them than for any of us) they would have had the chance to compare measurements of the Japan-DSLR-Solenoid with the China solenoid and it would have had to make "BOING" right away...i.e. a short notification to the manufacturer of the solenoid and all would have been solved.
They woke up in 2015 finally and only after a few K70 with the 2-nd generation solenoid failed as well they got it for final which I only can guess that it was in 2020.
