K5 lens calibration shifting?
I was doing a shoot in a studio on Saturday and when zooming in to 8X on the face on the rear screen to check focus it didn't look sharp, in the end I went back to using an older body to finish the shoot. Looking at the K5 images they do not appear as sharp as they have been in the past, they are s...

Pentax Auto Bellows & K5 advice needed
I have that bellows unit, Andy, & use it with my K7. Have you tried releasing the camera mounting ring from the unit? When looking from the camera end, it's the chrome/knurled locking knob on the right. Mount the camera to the ring then, with the rear standard as far back as it will go, locate t...

Pentax Auto Bellows & K5 advice needed
For what it's worth, I had the same problem with the MZ-S and found that any of the Pentax auto extension tubes can be used to retro-fit the bellows unit to the camera. I haven't had any real chance to take any pictures that way yet but I used a #1 tube to connect the camera body to the bellows. U...

ME-F Electronic focus indicator problem
Hi All, I've just picked up an ME-F which appears to have a fault with the electronic focus indicator. When turning the AF on (or activating the meter from a half press of the shutter relase), I get the 'in focus' indicator flashing green. This is immediatelty replaced with a continuous right poi...

ME-F Electronic focus indicator problem
Hi mate My MEF stopped working years ago, but here's what I would before deciding if its knackered. For your 1.7 lens make sure the switch is set to 2.8 Take out the batteries for a while just to reset the electronics and try again. Put new batteries in and if that don't work I would thi...

ME-F Electronic focus indicator problem
Given that even if the focus indicator is faulty you are still able to focus manually and that you have effectively turned it into an ME Super, it could still be a perfectly viable camera to use.

ME-F Electronic focus indicator problem
screwdriver - yes I'll try some new batteries, tried your other suggestions. john - thanks, the metering appears to run consistently (haven't checked it's calibration) and as long as this is separate from the AF electronics, it should be OK. I look forward to shooting with it. I was interested...

ME-F Electronic focus indicator problem
Yes, the exposure circuit is separate from the AF :D The exposure electronics is, IIRC, exactly the same as the ME-Super. Do watch out for the ISO/Ev dial - that was a common cause of exposure issue. Internally it's a ceramic variable resistor, and any dust or dirt would make it misread - drast...

Lens release on K5
The lens release button had disappeared from my K5, so at the moment I am stuck using just my DA 16-45mm, which is on the camera. I am going on holiday tomorrow, to Morocco and then Sri lanka, so the timing is not very good! Anyone any ideas how I can release the lens so I can use more than the one ...

Polariser and wide-angle lens
What would be the problem with a thin frame B&W polariser? The in built hood on the 15mm may not sit back far enough to allow the wider adapter flange for a Lee or Cokin type to fit properly. If it does fit, then so would a 49 > 77mm step up. Best regards

Polariser and wide-angle lens
I talked to Lee at Focus this week about vignetting on the 12-24mm pentax lens and DA15mm when using a polariser.I have been using a slim CP on the lens then the Lee holder and have been considering investing in the Lee CP. We did a test with the 12-24 and the Lee holder with Lee circular polariser...

Polariser and wide-angle lens
Chris, I use the Lee system with the 31mm successfully. I can't remember which forum I saw this on. I use a UV and a spacer ring and CPL then add the Lee wide angle adaptor. This works fine even with 2 slots, no vignetting. SRB can supply the spacer rings to specific lengths or use empty filter ri...

M lens focus barrel jamming
Hi All, Today my M 28/2.8 developed a clicking noise from the focus barrel at a particular point, this then got worse to the point where it is now jammed (I don't want to force it). It seemed to be fine yesterday. I've read a comment suggesting it might be a bearing, any help appreciated. J...

M lens focus barrel jamming
Might also be grit or a shard of something that's become lodged. Has the lens ever been bumped or dropped? Sounds like it needs to be taken apart for an internal clean and service. Time to call the pros.

Actually, this lens is quite a simple design and relatively easy to strip , without disturbing the optics too much. Regards Steve

Dreaded Message - Memory Card Error (K10D)
Thought I'd post my (unfortunate) experiences with the K10D as a little warning :P Quite a while ago I bought a partially defective K10D that had an intermittent memory card error message.
