Thanks all, and Matt and I did think about the colour temperature.

There's not a huge amount of difference, but the older body is marginally sharper with the same lens and setup. I may just be pixel-peeping her though.

More experimentation called for!!!

I was doing a shoot in a studio on Saturday and when zooming in to 8X on the face on the rear screen to check focus it didn't look sharp, in the end I went back to using an older body to finish the shoot.
Looking at the K5 images they do not appear as sharp as they have been in the past, they are sharp but not as sharp as they have been (this is at f8 so I didn't think it was a front or back-focussing problem)- I can usually see the goosebumps on the models skin

I did my normal lens calibration procedure and found that it had shifted from -9 previously to -4 now, and also doing some tests with the older body found that the K5 was not as sharp with the identical lens and setup - tripod, cable release, lens fine adjustment calibrated.

Any thoughts on whether this is a lens or body problem? The camera is still in warranty until May so I have a bit of time to try to sort the problem.

All suggestions most welcome.

Very well done Will, super panel and well above LRPS standard in my opinion.

Hmmmm, I'll have to think about that one.....

Seriously, I will look at improving my post-processing, which is a bit hit and miss at the moment.

Happy New Year.

Congratulations, superb shot, beautiful quality.

Thanks Steve, but I would suggest you recognise my images because of the subject matter rather than image style

Welcome back Pete.

In my experience when stopped down to f8 at A3 print size there is no discernible difference between most lenses, not that it stops me wanting more lenses

This is a blatant plug for two calendars I have produced this year, with all profits going to charity.

Thanks Mike and Shaun.

Mike, a lot of the images are similar because of the burst, but they are subtly different and not identical, and since memory is relatively cheap it's worth it to get a shot that may be just slightly better.
I probably shot around 400-500 different shots on Sunday and then the burst technique multiplied them up.
But each to their own technique.

I would definitely be interested in the location of the cottages, as I now have a very good model in north Wales. I know of one cottage near a reservoir.

Mike, I learnt this trick from another photographer, when shooting in natural light shoot off a burst of 4-5 when I would normally take one. One of them may be a wee bit sharper than the others, and also you get very slightly different poses and one may be a little bit better than the others.

Tried it when I did a shoot in Aberyswth on Sunday and took 2500 in 5 hours

Also when I shoot dancers in natural light I take loads of images at a time.
