Focusing problem
I photograph a lot of trains and use back button AF all the time. Was SR on? I have had some instances where shots in the middle of a sequence are soft (overall soft rather than just mis-focussed) which I blame on the SR still moving the sensor I have been thinking of getting the DA* 50 -135 but the...

Focusing problem
This may not be relevant to this issue - I've had a similar problem with my K-5 in the past when using manual focus lenses (more correctly - lenses that don't communicate focal length). If you don't set the focal length correctly, SR won't apply the correct 'corrections'. In my case it was set to 15...

Focusing problem
Going back to what the OP said in the beginning, I am not convinced that once the focus has been set (either by shutter or AF button) that the camera will maintain that focus position. i.e. on my K5, I think the focus position will move. Stephen, can you confirm if you used the AF button to pre-foc...

Focusing problem
Update: I wasn't able to identify what the specific problem was but I contacted SRS who asked me to send some sample pics. As the camera body was still under warranty, just, they then advised me to return it for service/repair, which I did. It came back from Johnson's Photopia with a note that, "...

very dark viewfinder image
I have a Pentax K-x, all the pictures on the playback screen are very dark in-spite the pictures being taken in bright sunlight. I cannot check the composition and quality of the picture taken until I get back home. Any suggestions would be welcome.

pentax z1 film won't read
I don't think DX coding (or dirty contacts) makes a difference - putting the film in, pulling the leader across and closing the back triggers the film loading sequence. Non-DX coding film is no different, it just defaults to ISO 100 - although it may flash the ISO icon on the LCD.

Decentered sensor..
OK issue has been resolved. I downloaded the debug file and corrected the focus issue. I read that some viewfinders are slightly out of kilter so it's not likely to be fixable as the parts aren't available anymore. I may or may not keep it, I'm giving it a run out this afternoon.

Decentered sensor..
As a lot of these issues are, it's reported on the US forum. I'm not saying that adjusting the focus has solved the issue but it doesn't appear to be as much of a major issue as it was. I'm just going through some pictures now- given the hellish contrast at the time I was taking the pictures(lovely...

light meter with smallest aperture
Assuming we are talking about K bayonet cameras and lenses, and looking for lenses that will work with modern DSLRs, then you need A series manual focus lenses and any AF lenses. Where there is an aperture ring on a lens, set it to "A" and all will be well. If there is an aperture ring but no "A"...

K3 Not keeping settings?
Hi all. My K3 and K3 II have started doing some weird and funky things, like changing ISO and f stop without being touched by me, and also, to use an example, I set ISO to match EV steps, so function 2 in custom settings, and it reverts back to 1 after every time it goes into standby. Anyone else e...

K3 Not keeping settings?
Are you using it in one of the three custom settings? Custom settings have to be purposefully saved in the menu system otherwise they will revert back to the saved ones when the camera is switched off. There is also a setting somewhere in which the user selects which settings are saved and which...

K3II - raw not being recorded
I was out yesterday with my K3II, which is set to record RAW + JPG, but when reviewing my shots later I realised that the first 15 or so shots where recorded as JPG only. I'm assuming I did something, but no idea what. Later shots were recorded RAW + JPG. The camera was switched off whenever I ch...

K50 won't switch to manual focus
Hi yall, I've recently started having a slew of problems with my K50. First the aperture demon flared up and I removed the shell and fixed it, I also soldered a wire that I had pulled while removing the case. Everything worked for a couple of weeks or so then it occasionally dies while using i...

K50 won't switch to manual focus
I do believe all this is related to some internal electrical problem. I have an email into a local Pentax authorized repair asking for a quote on getting it fixed. I hear the shutter click when the power returns meaning it was the shutter all the while.

Image Count
Sharp files are bigger. Pentax probably assume that you will be getting shots that are sharp.... in focus etc. --
