The purpose of this poll is to try to find out how many of the K-30/50 that have had aperture block failure have also developed shutter block failure. The results will help establish whether both issues are related or not and if the aperture block failure represents the first stage of a bigger problem.

Please answer the following questions with either a Yes or a No:

1.- Did your K-30/50 have aperture block failure?
2.- Did your K-30/50 have shutter block failure?
3.- In case you have answered Yes to the above two questions, was the aperture block failure prior to the shutter block failure?


Thanks in advance to all participants
We know that the "aperture block failure" is really the failure of a solenoid. I don't believe that the failure of an aperture solenoid could have any effect on the shutter system. The two systems are unrelated. Could both systems fail? Of course, but their failure cannot be related.

1. Yes, my K50 had an aperture problem. I bought a set of AA batteries and that was fixed for awhile. But now the problem returned and this time it seemed permanently. I tried the fix that people reported in this forums but accidentally shorted the flash capacitor and the camera won't turn on after that. Still didn't see any apparently faulty components. I will look into it in the future to see if I could fix it but I guess the chance is slim at this point.
2. No.
3. N/A

I am looking for a new camera and I did think about Canon or Nikon or Sony but I can't shake the feeling I have for Pentax. I guess I just go with another Pentax body, this time a used one (possibly a K10D or K20D because that's all I can afford right now).

1. No

2. No

3. na
Update: my K-30 started having what I call 'Dark Image Syndrome' at the end of May, when shutter count was approx 3023, and I had been using it for just about 3 years, mostly with AA batteries.

Ever since then, a few exposures are required to get it working at beginning of each day.

The shutter seems to still work normally.

Useless survey

This is a totally useless survey!

Because even if anybody with answer 2. with yes, it will not be any prove that the two issues are linked.

The shutterblock has two independant solenoids (more powerful)

Allthough both, the aperture block and the shutter block... work of course together, a damage of the solenoid will not affect the shutterblock.

Or lets have a look from a different angle:

To start a survey like this means I understand enough of what's going on inside a Pentax DSLR with a solenoid in use.

And I know enough about how a shutterblock works.

Aperture Block Failure means the camera body can no longer correctly set aperture of the lens; the photo is very dark, but present. There are two 'sticky' "Dark Exposure" threads at the top of this Section.




Any type of "shutter" failure means exactly what it sounds like - the camera doesn't actually take a photo when you press the button.
