No more Pentax for me!...
Pffft. I can't imagine what sort of response you expected when you started a thread with a provocative title like this one. And then back it up with very tenuous reasoning. As far as i can make out your primary issue is your apparent inability to mentally multiply focal lengths by a factor of 1....

No more Pentax for me!...
I do wish people would read and understand what I have written in this thread before commenting. I am beginning to think that some of you are deliberately misunderstanding. For the last time... IT IS ABOUT THE LENSES!!!!!.. ONLY THE LENSES!! I have a lot of lenses, some very expensive, some ve...

How to avoid back-focus problem when focus-recompose?
Hi guys I just realized when you are using a telephoto lens to shoot a portrait, 'AF first and then recompose' brings a back-focus problem. Could you explain how I can lessen the 'out of focus' effect? MF?- -! Thank you. Peng

MF is the answer I'm afraid, either that or put the feature in question (eyes or whatever) directly on one of the AF points.

With DA lenses the answer is to AF and then tweak the focus manually using the Quick Shift feature. No need to change to MF to do this. The exception within the range will be the 18-250mm and the DA-L lenses.

How to avoid back-focus problem when focus-recompose?
If your AF is accurate, you shouldn't have a back focus problem when you focus and recompose. Your AF might need to be adjusted. If your camera pre-dates the K20D, or any model that doesn't have a focus adjustment, you should send it with the lenses to Pentax to have it re-calibrated. On the ...

How to avoid back-focus problem when focus-recompose?
If your AF is accurate, you shouldn't have a back focus problem when you focus and recompose. That's not true i'm afraid, unless the DOF of your lens isn't flat... telephoto fisheye maybe? Here is an image of the problem to make it clearer. If you've an AF with multiple focus points you can...

How to avoid back-focus problem when focus-recompose?
Does it help to use the menu option to disable focussing on half-press of shutter release and use the AF button to focus on the subject? You can then re-compose without the camera trying to focus again. Just a thought :wink: Myles

The camera won't refocus if you keep the half pressure on the shutter release.

How to avoid back-focus problem when focus-recompose?
99% of the time, the error is going to be so small, it won't be noticeable. That depends on so many things i don't want to say a percentage. I do agree with you that the error is small most of the time but if you've only millimetres of playing room that small error will be noticeable. Just try to ...

How to avoid back-focus problem when focus-recompose?
Just try to recompose with macro photography or portrait with a very fast lens that gives a very small dof. Or indeed, with extreme wide angle lenses.

GX-10 (K10D) and Auto Bracketing????
Hi all, After problem number one is sorted (How to get Contact Sheets in Corel Draw, thanks to Daniel Bridge :) ) I have another question if I may. Is it possible to 'shoot' in RAW+ (RAW plus JPEG files) AND stay in bracketing mode automatically without having to press the bracketing button every ...

GX-10 (K10D) and Auto Bracketing????
You can get split circle focus screens on ebay, made in China apparently by grinding down screens from old film cameras, for very little (£5-15 if I recall correctly, I got mine years ago). Or you can get a made in America one from Katz Eye for about £100... The Katz Eye is supposed to have better Q...

GX-10 (K10D) and Auto Bracketing????
I had a cheap ebay split focus screen in my old k10d and it worked very well. The only thing I did notice when I got my gx-20 is that the standard screen is noticibly brighter.

Hi all, many thanks for all your replies and opinions. First off I do have 4 cards that I rotate on a regular base. I also had issues with several card readers and as pictures are pressures to me I usually make first a back-up via the cable before I use an external card reader as this way I at lea...
