I adjusted the K10 to +350 microns and the improvements speak for themselves. First attempt at this, this was with the Tamron 28 - 300 which backfocussed. This picture was focussed half way across the face of the flower head. Taken on a tripod with SR off and 2 second delay with mirror up to eliminate shake. As an aside I have noticed how the K10 has a huge "clunk" as the shutter operates compared to the soft "glide" of the k20.

Please can I have some instructions for placing pictures into posts.

Yves, I feel very pained for you and your wife. It is good that you feel able to talk with your fellow Pentax friends thoughout the world. Life with our pets goes very deep and it`s a very special relationship.

My thoughts and feeling go out to you.

I have recently bought a kit of three 2, 4 and 8 and holder. So far I have only tried out the grade 4 and that seriously darkens the sky. used it at the shorline on a very sunny day with cumulus clouds begging to be shot. I would guess that using grade 8 in the same situation would make a very dramatic sky.

Thanks Peter, that is the software I downloaded and used it via USB.

Very grateful for your help though, will post some shots before and after if I find it is out of kilter.

Thanks Steve, I will carry out a series of shots as per the thoughts of Yvon Borque. Just need a little time. At present the K10 is set at the zero or centre position. Had a few comments refering to back focus but I need to be a little more scientific. In particular my Tamron 28-300 is the worst offender but the standard lens and Pentax 50-200 also have the same trait to a lesser degree. I guess it`s best to try all lenses and then decide an average change to the focal point which is acceptable overall. Now iv`e got a K20 D I can afford to adjust the K10 so I have left debug mode enabled. I used the Tamron on my K20 last night and the results were amazing, that proves the lens quality. Aside from making a change which will average out the issue I think If I test shoot all my lenses and make notes I could leave debug mode enabled and make changes via the menu for each lens change. A blacksmith engineering solution to what the K20 has as standard but a way around a problem, I hope.

Cedric

Thanks gents, I have a much better idea now. Will set to it at the weekend.

Very grateful for your help.

Iv`e downloaded the software which enables me to switch DEBUG on and off via a USB cable, that`s fine. What on earth do I do to find the DEBUG menu in the K10 and does anyone have instructions please for altering the focus. I have also downloaded the charts for focus testing from Yvon Borque.

Cedric

Thanks John, just a bit neurotic!
