Still a good and durable camera on low ISO and enough light. Try to use fix lenses as DA 35mm f/2,8 or DA 50mm f/1,7.
But friendly advice for newbies: don't collect too much lenses!

I've bought new wide lens Irix 11mm f/4 and tried to use it with Pentax Super Program film SLR. But... I can't fix it on the camera. It stucks in the bayonet and unable to rotate inside.
Probably, I found the reason: there are no recess for aperture lever as usually is on all Pentax lenses.



It can not be fixed because this lever:



Are any ideas how to use this lens on Pentax film cameras?

Focus problems DA 18-135

Hello, I am also having a trouble with 18-135 autofocus.
An autofocus is not working continiously. The lens makes one short jog when I'm half-pressing the shutter button but doesn't move on. This sounds like fast and short "jeeeg".
So, I can focus but need to press shutter button for a dozen times.
Same is in any AF and LV mode. Screw-drive lenses are working well.

I've cleaned electronic contacts but nothing changed. Does anyone have any suggestions?

There is video, it may helps to understand.

Pentax Super Program (SuperA) display fade

Battery has been replaced for fresh SR44 and bottom cover cleaned, but nothing changes.
I have read about repair LCD displays in watches. Usually, it looks faded because of degradation of polarization film.

Will be appreciated, if somebody have photos of videos how this display fixed inside the camera. Can not find any information about disassambling of Super Program or Super A.

Pads and seals sources?

I've bought light seals from China on Ebay (nearly $6 per 4" x 8" sheet). It is not bad, but adhesive layer looks weak. Only for very clean surface.
Pre-cut is usually overpriced and gives no chance for mistakes.

Pentax Super Program (SuperA) display fade

I've just got Pentax Super Program in nice condition. It works well, but inner LCD display in viewfinder looks faded and pale. All digital are visible but it feels like at low battery.

Other display on top side is bright and contrast.

What can cause it? Oxidized contact? Degradation of liquid crystals?

Can not find any information about display repair or replacing.

I know about this feature. After rewind to 1st frame in "auto" mode exposure metering works fine. LCD indicates different values. But ISO speed selector have no affects.

I have found ME Super disassembled manual. There is potentiometer with lever. SuperA should be similar.

Hello, I have just bought used Pentax Super A.
It looks like camera has not been used for a long time.
There is problem with ISO/ASA dial ring. I can rotate the ring inside but exposure metering is not changing.
ISO always stuck nearly 200. Also exposure correction doesn't work too.
What are possible reasons? Can it be caused by oxidizing?
Maybe someone have an idea what about it?

Is there variable resistor inside?
