K7 to buy or not to buy ????
Better image quality....no. If you prefer JPEG I would suggest sticking with the K20D. The K-7 needs to be used in RAW especially at higher ISO. Better at quite a lot else though. I wouldn't go back. The things I've noticed are: (1) I much prefer the smaller size. Clearly a matter of pers...

K7 to buy or not to buy ????
Doug - the K-7 with your Nokton lens on the front of it will make you very happy indeed! Looks really good too, even though that doesn't matter (much):D I would recommend getting the WR kit lens(es) as the freedom of being able to go out in the rain without worrying is great. If you get one and...

Focus adustment on a K10D
For the last few months I have been noticing my K10D has been losing the sharpness I had when I first got it so decided to have a play with the hack that allows you to enter the debug menu for focus correction. This morning I stuck the F* 300mm and 1.7x teleconverter on and did some adjustment .. fi...

Focus adustment on a K10D
I've dialled +60 in on mine for the 50-135 Mike, for when I use autofocus with it. Everything else seems to use zero (tested using a focus chart FWIW), so it's actually more convenient not to say accurate to use manual focus, given it is easy to forget to make the adjustment every time you switch l...

Focus adustment on a K10D
I've wondered on a couple of occasions about the sharpness of my 16-50 on my K10D, though everything else seems ok, I did consider having a go at this hacking business but as the body is now an almost permanent home to the 50-135 I think things are best left alone:D

Focus adustment on a K10D
Mine seems to be out on everything. It strikes me that this is likely to be a physical misalignment through age. Something has worn or become out of adjustment, maybe the mirror assemply, maybe some wear in the AF mechanism. If so, it will no doubt drift again as time goes by.

Focus adustment on a K10D
Mike, I totally agree. I set debug mode to be active all the time and dialled up plus 150 little bits and it is sharp. The best lens for it is my DA 50-200. Crystal clear throughout. Tamron 28-300 is a bit fuzzy at the long end but if I bring it back to say 280mm it`s ok. Cedric

Focus adustment on a K10D
I know I keep on about this but it's like having a new camera. Had to do a couple of pics for my FA* 200mm sale and this is the result. These were obviously resized for flickr and have lost detail but even so. To be honest I may even keep the FA* now. Not the best subject in the world and han...

Focus adustment on a K10D
Reading this thread inspired me to have a go at my K10D this week. I have been bugged for a while now by the fact that my 16-45 would rarely lock on focus with distant shots at wide angle. I kept having to zoom in a bit, lock focus then zoom back out. Not had chance to test the full extent of the ad...

Focus adustment on a K10D
This is actually a bad idea these days as many zooms do not hold focus when we zoom. Technically, they are not true zooms, but variable focal length lenses. The kit lens will show this very clearly - focus at one length and then zoom, watching how the image blurs.

Focus adustment on a K10D
John, Thats an interesting take on zoom lenses - have just tried it with 2 pairs of bin's and they work fine. So is this a feature of current digital only zooms or present in older analog designs? I would have thought that a Canon (sorry) 100-300mm F2.8 would hold focus start to finish, else t...

Focus adustment on a K10D
As well as all the corrections needed to manitain performance over all focal lengths, one of the compromises that has to be made is that of holding focus. This will depend on the lens desigmn, but also on the quality of the mechanical components as well. A Leica zoom might be expected to hold its...

Focus adustment on a K10D
Mike, On account of your article here, you had me looking at my AF, and sure enough, things were not the way they once were! What also prompted me was an hour or so down at the local creek today, shooting ducks using continuous autofocus (being lazy). I got home to find that there were very few...

Focus adustment on a K10D
I'm glad someone found it useful anyway .. it has made a huge difference to my K10D. It really is like having a new camera (and mine also seems to be better on all lenses including zooms) 80% crop taken yesterday with F* 300mm and 1.7x teleconverter.

Focus adustment on a K10D
I've followed this thread with interest because I sometimes feel I'm not getting optimum sharpness with the DA*50-135mm lens on a K10D. Even allowing for my reluctance to use a tripod I'm sure there is scope for 'could do better.' So what is this hack MikeP is on about and how do I get into it? da...
