Originally posted by sajah I'm wondering about this bug mentioned in DPReviews forum when K-01 just came out, has it been fixed with the new firmware?
It's hard to explain the bug so I'll just copy paste it here:
To be honest I don't completely understand what the guy said and I don't have access to that review by Sean Reid. But since he said Ricoh GXR and Fuji cameras also have the same problem I assume the problem is real.
I tried out an old manual focus Pentax Takumar 28-80 lens on my K-01 this morning. It's not a great lens (the later AF 28-80 is much better).
I could find no significant issues with Manually focussing using Focus Peaking at a variety of Aperture settings. I did notice that in some circumstances the aperture blades do open/close BEFORE depressing the shutter,but I believe this is by design - not a bug. In Av mode and whether or not the camera is being manually or automatically focussed, when the sensor detects a significant change in exposure for example by moving the camera view from a dark to a light area, the aperture blades appear to close as part of the re-setting of the shutter speed (although I'm not sure why they don't close all the way to the set F stop). Personally however I found this has little effect on focus peaking and to be honest - if you are moving the camera around you may need to re-focus anyway.
Since the Firmware update, my only remaining concerns about this otherwise fantastic camera are:
Incompatibility with my Sigma EF530 DG ST Flash (for Pentax P-TTL cameras). I really don't want to have to buy another flash that I won't use very often anyway.
Difficulty in viewing Liveview screen when pointing TOWARDS the sun (but this can be significantly reduced as a problem by increasing display brigtness and ensuring I wear a dark shirt or coat when taking photos!)
