Hi all,
Opinions please!!! This is kinda long so if you stick with it - THANKS!!!
I recently started to notice that some of my shots from the D200 were not as sharp as I would have expected. Presuming it was my technique, I started to try all kinds of things - faster shutter speeds, using a tripod all the time... The only way I could actually get any kind of sharpness was to stop it right down to F16 or lower.
I got a focus test chart from Tim Jackson's site (CLICKY) and started to shoot as described, finding that depending on the focal length used, my focus was between 4mm and 10mm behind where I thought it should be.
So I set everything up, used the D200 and the D40, both with an 18-200 and 55-200 lens - and the results can be seen at the link below.
D200 vs. D40 Focus Test
The same settings were used (apart from WB as you'll see :bang: but I think they show the D200 as having 4-10mm of back focus.
Before I send it in to be checked - any opinions? Something I am doing wrong?
I gave both cameras a factory reset before the test, the only thing that I changed after that was the WB on the D200 and to make them both shoot in RAW. Both lenses had their filters removed, ISO was a constant 200, both cameras on a sturdy tripod and a remote shutter release was used for both cameras.
No processing aside from resizing, JPEG'ing (at 100%) and cropping has been done on any of the images - resulting in a 100% crop.
Both
