AM/FM button on lens may harm the lens?

I don't know about lenses, but I've seen a lot of things that have a "mechanical fuse", i.e. something inexpensive/easy to repair that breaks before damage may occur to more critical parts of a system. It would certainly make sense to design an AF lens like this, and also for the manufacturer to urge caution when operating the lens in MF because of this very reason.

My Sigma 30/1.4 (screwdrive/non-HSM) has a focus ring that is always engaged with the AF motor. At some point, the focus mechanism locked up, evidently a mechanical fault. My memory is foggy as to whether this happened before or after someone at a party tried to zoom the lens with the focus ring, though it didn't break immediately after the mishandling.

I'm strictly a hobbyist. Looks good to me, even if the colours are somewhat strong. Maybe it's down to screen calibration? The variation between computer screens is pretty huge at times.

Also, while Facebook is a nice social arena, I'd love to see your pictures uncompressed - I feel like I'm missing out on something.

Auto-Tak 55/2.2 - Cocking lever repair
Posted By KjetilH
Replies: 0
Views: 686
Got this lens with an H3/S3. It works perfectly well, except the cocking lever wouldn't work. While I'm new to screwmount lenses, I know the basics, and tried fiddling with the pin that lets the camera stop down and the cocking lever itself. It seems like the pin was stuck pressed down, which is why the cocking lever didn't work.

Basically, I'm now able to get the aperture to cock if I press the pin down manually first - itt does feel a bit 'dry' (i.e. no lube) at least most of the time. Thus I'm asking if anyone knows how to fix it. I've done some basic relubing/cleaning in the past, but I'd prefer an easy solution. If it gets better by exercise or with a drop of oil on the pin, all the better.

Lubing the pin did the trick. It now cocks every time. Not too sure lubricant is the best, but I had some lithium grease left over from repairing my K50/1.4, and applied it via a cotton swab, then actuating the pin a few times.

I could actually see myself having a GXR with a K module as well as a small-sensor compact/superzoom or a small APS-C prime module. Would cover most of my needs, size wouldn't be an issue for the K-module.

I suggest you make a new thread. A tip is to take off the lens and check if the aperture feeler lever (right side when looking at the mirror) is stuck. It may need a CLA or some light cleaning.

Takumar 135mm 2.5 K mount version?

Rumor has it that this lens exists in two versions, one of which is better than the other and marked "Asahi Opt. Co. Japan (...)". The golden JDMC mark gives it away too.
No particular evidence for this, but may be something to remember. It also seems to be one of the few Pentax lenses with half aperture stops throughout the range, which is a bit weird, I think, given how the aperture stops are for the SMC lenses.

Buy an used Sigma 10-20/4-5.6, then sell it when/if the 12-35 comes out. There will be a loss, but pretty minor anyway, and it would be money well spent 'renting' it if it is a long wait.
Worst case: The 12-35 is vapourware, and you have found out whether 10/12mm at the wide end would do the trick or that you are better off with the 8-16.

ME Super Size with ASA 3200?
Posted By KjetilH
Replies: 14
Views: 3,284
While the P-series are generally good bodies for their intended use, the upper limit for ISO (DX-coded) is 1600. I'd suggest a Chinon CE-4(s) too. From experience it feels a little cheap, but the shutter wheel is a nice alternative to the ME Super selector and buttons. Note, however, that there is no 'mechanical' shutter speed as on the ME S. It needs (three) standard SR/LR44 to function at all.

Pentax MX

Pros Size, build quality, features, viewfinder Cons Film counter failure, used prices Rating 8 Price (U.S. Dollars) 40 Years Owned 1

I can recommend this camera: Yes

Value, Features, Performance & Size
I find the MX a great camera for 'casual' use, with a good feature set, a magnificent viewfinder and its small size. The metering system is very good, I find the LEDs better than using a needle showing speeds or over-/underexposure.

Camera Review
I like the MX a lot, in fact maybe even more than the Nikon FM, which, apart from size, is very similar in a lot of aspects. The five-LED metering system is easy to read in all situations, which I enjoy a lot, and having both shutter and aperture read-out in the viewfinder is a luxury in itself. The meter turns on while half-pressing the shutter and stays on when the wind lever is at the stand-off angle. The viewfinder itself is one of the largest in the 35mm SLR world, and very nice and bright.
The MX is easily handled even with bigger lenses, but some of its appeal is being used with a few M-series primes. I mostly use it with a K50/1.4, M50/1.7, M40/2.8 or a K105/2.8. Especially the 40mm makes the camera essentially pocketable and very stealthy.

I have yet to experience any major faults with the MX, the only thing being the film counter, which doesn't work. Not a terribly big deal, but it's nevertheless something to watch out for. I got mine for a quite low price from a private seller, considering its good shape and being CLAed some time during the 90s.
I've noticed high prices for this camera elsewhere, probably due to its cult status and relatively high collector value.

I consider this one of the 'ultimate' camera bodies in terms of usability, and perhaps my favourite Pentax camera.

If you are to buy one, check for typical 'fall damage' (dents), if the film counter works, light meter switch, the meter itself and if it responds correctly as well as noting whether the mechanical shutter works correctly at all speeds. Run it a few times at low shutter speeds to check the mechanism, as well as the 1/1000 s. speed. From what I've gathered, the errors on most SLRs show themselves at slow and very fast speeds. Also, a MX with a plastic film holder (wider than the metal one) should be more refined than the older ones. I doubt all fixes to the design came at once, but it's nevertheless something to look for.

Doing the Pentax flick!
As a follow-up to the above review, my MX is not easily 'flicked' the way described. I think I've managed it once by accident, though. Mine is a later model (plastic film reminder holder), it would be interesting to determine if the 'flick' is easier on older cameras.

Pros Simple, reliable and quite rugged Cons Noisy winder, no M mode, no exp. lock. Rating 6 Price (U.S. Dollars) 15 Years Owned 1

I can recommend this camera: Yes

Value, Features, Performance & Size
Collector value is about none. Winder is fast but noisy. Body is larger than the older M-series, mostly due to use of 2xAA batteries. Very easy to use, but not a lot of features.

Camera Review
Arguably a camera targeted at beginners, it offers a similar feature level as the older ME, while also including an automatic winder.

There is no EV comp. wheel as on the ME series (aside from the backlight +1.5EV comp.), but it's easy to achieve by setting the ISO manually (taping the DX contacts on the film canister) and compensating by setting film speed instead.

Probably one of the cheaper choices of older amateur-level SLRs, it even runs off two AA batteries. Also, my sample does not have any light seals at the back, which makes for one less thing to check for. If you are to buy one, check if the camera seems to work normally (shutter, mirror, normal winder noise without loud 'clicks') and see if the meter responds. Move the aperture feeler lever (2 o'clock looking into the mount) if you don't have a lens on-hand.

Personally, I prefer my MX or K2, but for just trying film out, it is a decent choice, even though most of the P-series bodies also are cheap, reliable and easy-operated.
(But then again, considering used prices today, there's not really any bad Pentax SLRs, at least among the pre-AF-series. I got mine practically for free with an A50/1.7 and case, all in mint condition.)

Fault with ME Super, winder and shutter jam.
Posted By KjetilH
Replies: 10
Views: 14,350
I am by no means an expert, but I bought a ME F and a Super yesterday, both of which had problems with the shutter/mirror. The Super had a locked up shutter, which was fixed after shaking it quite violently (some of it was a bit rusty, which locked it open) The F first had problems with the shutter not going back to the normal 'after-shot' position*, then the shutter did not fire although the winder mechanism worked** (like your problem, apparently).

* Standard solution is to nudge the shutter curtain into place with a fingernail.

** It's caused by the wind mechanism not being able to perform the final 'lock' in which the shutter is set ready for the firing action. There's no visual sign of this, and barely any audible. Apart from just exercising it (without the winder), the common solution seems to use the wind lever and wind about halfway (1/3 or 2/3 seemed to work too), stop, and then wind it fully. After a while of this, the ME F fired as normal, going from one shutter action every five or six winds to every second and then being fully reliable.

Apologies for the quirky English and good luck. If the above doesn't fit your problem, then please describe the state of the shutter and mirror, which often is a good clue.

Repairing the cameras may not be worth it (unless it needs a CLA anyway, of course), but a name that came to my mind is Harrow Technical:

S25 close up lens
Posted By KjetilH
Replies: 8
Views: 3,766
The S25 ('S' for 'standard lens) is, according to this site a single-element closeup filter, and thus not an achromat. If I've understood correctly, achromatic close-up filters are superior to non-achromats in image quality, regardless of coating.

Another aspect could be that it's meant to be used on focal lengths ~50mm. How does it do on your 50/1.4?
(I suppose the old 50 and the S25 would be an optimal combination, given the S25s age.)

I never disassembled it, as the screws simply were too tight, and I was worried about ruining them.

After coming across a note on regarding battery connectivity, I checked all contacts. After cleaning with vinegar and scraping dirt away with a screwdriver, it seems dead reliable.

As you may want a comparison with a 70-200 or the 50-135, I could also review the 35-105.

The manual provides quite useful information. You may find the proper manual at

Note that the P30 and P30n/t are somewhat different cameras, though not by much. The manual explains quite basic concepts of 35mm photography, and is intended for beginners.

(Although the quick general guide for the P30(t/n) would be to put both shutter wheel and aperture ring at the green 'A' posistion. It can also be useful to know how to utilize the exposure lock, which is used when you have a bright background behind a dark-ish subject.)

Butkus also provides manuals for Pentax flashes. If it isn't a Pentax flash, then please post the make and model for a short explanation.
