They are all the L-90.

If I can find it and it is good I'll sell it to you, I have no plans to change back.

The only directly compatible screens are other DSLRs, the K200D, K-m/K2000, K-x and K-r.

I do still have my original K100D screen somewhere, it should be in perfect shape.

K100D Focus Screen

The original is the L-90, none of the replacement screens Pentax sells will fit because officially the K100D does not have a replaceable screen. Of course the screen can be replaced and there are many non-Pentax options available. I put a split prism in my K100D, it is nice for focusing makes spot metering useless. My K-5 has a Canon S-type cut to fit by focusingscreen.com and I like it a lot.

Have you removed the screen to check for debris?

Also, be very careful with compressed air in a camera.

Removal of lens from K2000

Sears lenses in general are good, check out the Sears Lens Club. I believe the Korean made Sears lenses were made by Samyang. I have a Sears 135mm f2.8 "Macro Zone" that was made in Korea that is also a decent performer, but with an interesting glowing soft focus effect when the "macro" mode is enabled.

I got my 60-300mm in a lot with some other stuff, I wasn't expecting much out of it but it definitely impressed me. They don't have much of a reputation and they are plentiful, so they never sell for much, they are a good value.

That one is really easy, just take the 4 mount screws off and remove the mount. The pin has a little bracket over it with a resistor attached to a screw. Make sure you don't remove the other pin, that one is necessary for automated metering with Pentax. The resistor isn't necessary for Pentax either.

These things have some pretty serious "zoom creep", but one of those thick vegetable rubber bands works perfectly.

This was at 300mm and f8.

It takes some wiggling and sometimes flipping the AF switch ON/OFF to coax that pin out of the AF drive hole.

The good news is it should never happen again because you'll always check for that pin when getting another 3rd party lens.

Definitely the Ricoh pin, I have one of those and it had the pin. Pretty decent lens for what it is, really good close focus capability at 300mm.

Flash stopped working K200

If you want to keep P-TTL, a Metz 36AF-5 is $100 brand new and a decent upgrade over the pop-up flash. Any repair is likely going to cost at least $100.

If the metering is compensating then it should be charging and giving the ready signal, so the capacitor is likely fine, it is possible that it is just the bulb.

Bulb Shooting

It was taking a dark frame, a second exposure with the shutter closed so it can map and remove the noise created by the extremely long exposure, this exposure is exactly as long as the first. In the capture menu it is called "Slow Shutter Noise Reduction". However, you really shouldn't be taking 45 minute exposures, the results are going to be terrible. Stacking multiple shorter exposures will give much better results.

How much was ambient contributing to the exposure? To freeze action with a flash the ambient must be underexposed.

I don't know anything about the design of that particular lens. If it is a loose element then your image quality is going to suffer greatly. It could also just be normal movement of some of the mechanical parts inside the lens.

I looked at other pictures of a Kalt 28/2.8 and it is not like any 28 I've seen before, I have no idea who the original manufacturer could be.

ME super lenses on digital

In general yes, every Pentax branded lens that fit the ME fits the new Pentax DSLRs.

There are incompatibilities with third party lenses, but a majority will be fine. For example the Ricoh pin that can get stuck in the AF drive or the oversized aperture lever shield often found on Vivitar lenses that hits the mirror box and won't allow them to be mounted. These are easily handled though, that pin can be removed and the shield can be removed or modified.

Please help to identify this 135mm f2.8 lens

Might be branded somewhere other than the name ring, one of my Korean made Sears lenses only says Sears near the aperture ring and it is easy to miss. Could have just been a mistake, the serial number looks normal. Someone might have even ordered some unbranded. Hard to tell what happened looking back on it 30 years later.


I still haven't seen any definitive evidence of who made them. It is odd that they show up as Japanese and Korean made.

You can commonly find it as a Sears and JCPenney, they are made in Korea. I have it under Sears with the "Macro Zone" feature that is more of a soft focus feature when enabled than anything resembling macro. I like it a lot, nice and sharp with good color when not in "macro" mode.

Here it is an identical one branded as a Praktica (East German), but still made in Korea.

I have my doubts that it is related to the famous Pentacon like they claim.

To optically trigger the YN-560 the camera must be in normal flash mode and the flash should be in S2 mode. It won't work with the onboard flash in wireless mode.

The one with the kit lens at f11 is 1/100s, the one with the 28 is 1/2500, that 28 was wide open and not at f11 regardless of what the ring was set on. When not mounted you can turn the aperture ring and it will move the blades, but once you mount it the lens is held wide open with the aperture lever. In Av mode the camera is not going to release the aperture lever to allow the lens to stop down.

I can see this clearly in the EXIF, you were using Av mode, you can't use Av mode with that lens.

For f2.8 that doesn't look terrible, by f5.6 it should look pretty good.

EDIT: Looking again, even in M mode it is not going to work properly right now. That mount is non-conductive and not shorting the contacts of the camera mount. The camera think it is an M42 lens, it is not going to try to release the aperture lever. You need to short the contacts for it to work, either by adding some foil or removing the anodizing from the mount. It says "M42 or no lens" in the EXIF, it should say "K, M lens".

You can't use Av mode with a K mount lens that doesn't have A contacts, the lens doesn't stop down. You must use M mode and the green button.

Different from mine as well.

That lever is definitely not resting in the proper position. Looking at it from the perspective of the second picture it should be all the way to the left. You don't have anything to lose by opening it.

Which version is it? There were a few different Rikenon 50/2s.

Someone might have had it apart and put something together wrong. If it is the same as my later model plastic version I could possibly help.

It doesn't matter what the prices are in the US or other countries, if that is what it costs to get one in Argentina, that is what it costs. That Pentax M's asking price was lower than any other lens he asked about, they wanted 900ARS for the Vivitars and 950ARS for the Tokina.

That Vivitar isn't a K mount either, it is hard to tell from the picture but it looks like Contax/Yashica mount.

I'd go for the Pentax M if the price is reasonable for you. Google says 850ARS is about 100USD. That is high for the US, but I understand the markets are different.

Are those the pictures of the actual lenses? If so that Vivitar is a Cosina and has been messed with by a potentially incompetent person. The Tokina is a Nikon mount.
