Could you take a couple of shots using LV, so we can see what the framing is like?

Wearing glasses wouldn't produce the vignetting Ken, but I'm intrigued by the fact that the only common factor in this is you Peter.

Welcome. My K20D is still a favourite of mine, although it hasn't seen much use since I bought a K5II a year or so ago.

Don't worry about the glass; it's you who makes the picture

DOF Calculator - does what the title suggests.

OS Grab-a-gridref - good for confirming both your OS map ref and Lat/Long.

PHOforPHO - another tool kit

Jules went Fuji, although he kept it a bit quiet. As I also shoot Fuji I found him on a Fuji Forum.

There's no hiding place from us Pentaxians.

Lens now sold. Thanks for looking.

I personally think that given you were shooting at 2000th that what you see is as good as it gets. It's a huge ask for a lens to stop down that quickly and settle into a perfect circle; just think of the inertia!

I'd try again at slower speeds and see what results you get then.

By the way, I really like your cherry blossom shots.
