Is this photo a crop? I assume it is from the strange dimensions of it. What is the Exif?

Here's a tele shot of a fixed object, screwed to a wall, so no problem with movement of the subject. Tripod, and remote release. I can vouch for all my teles producing photos like this, saving me the need to post a photo of each of the lenses

Hiya - no, only the Pentacon is M42. The Viv is a K mount, and the Tamron is an Adaptall.

Also, the little Viv 19mm W/A is K mount, and since W/A lenses take in a lot of distance, its pretty much the same outcome as the Teles, as i mentioned.

It just seems that any pics where distance is invloved, the pics are just not focused properly, and the macro shots seem to be ok.

The 300mm is a Vivitar 100-300 constant F5, the 350mm is a Tamron 70-350mm constant F4.5, and the 500 is a Pentacon 500mm F5.6.

I have also have / tried my Vivitar wide angle 19mm, and same problem. Its only close work where focus seems to be sharp

Hi guys - yes, all lenses are manual. I have dioptre adjustment sorted, but i also used ' snap-in-focus ' to make sure my eyes were not letting me down. No difference. Now then, i was under the impression that SR is disabled when using a cable release, because the camera brain assumes you're using a tripod ( and i was ) so SR is shut off.

I do get focus point ( red square ) and focus confirm ( green hex ) both when using ' snap-in-focus ' and also when i decide to press the shutter.

I've tried both spot and centre metering. I've aso tried a different focus screen.

I wear glasses, but not when taking photos. I'm assuming any discrepancies with focus screen and diopter adjustments are eliminated when using 'snap-in-focus' as the focusing does not rely on good eyesight or which screen is fitted. Plus cable release and tripod eliminating shake, and i've more or less taken me, as the problem, out of the equation.

I could post some pics, but i need to set up the cam and tripod, so i'll get back with those

My K10D seems to never focus properly at distance. I have 300mm / 350mm / 500mm lenses, and i get blurred pics with all of them. And thats with a tripod and remote cable release, so that i eliminated user shake.

If i switch to my Macro lens - a Panagor 90mm true 1:1 - i get nice sharp pics.

I was wondering if any experienced K10D owners/users/ex owners would like to meet up, and have a go at shooting with my K10D. Strange request, i know, but this would at least eliminate myself from the equation. Any K10 veterans in Oxfordshire or surrounding counties ? Bucks, Gloucestershire, etc ?

Cheers
Pete
