It made my wife more comfortable at the beginning!

John, that's why I said a small majority of judges, and I would agree with you about female photographers, hence why when I started out it was with two female photographers, and I have worked with many female photographers successfully since.

Hi Thank you Lü, and I believe only an extremely small proportion of UK camera club judges are negative about nudes, but if I enter an exhibition where one of them is judging then I have wasted my money, and once that has happened a couple of time you tend to give up.

Why are they negative? Probably because they think nudity=sex, whereas I what I am trying to achieve is nudity=beauty. They are obviously right, and Botticelli, Michelangelo, all the pre-Raphaelites, cezanne, gaugin, klimt and the majority of the great artists who have ever lived are wrong!

Thank you all, it was a nice goal to finally get to.

Thanks McBrian, I will give that a go.

Ok, I have a few lenses which required quite high -'ve AF adjustment on my K5, and all lenses seem to requires a negative adjustment.

So is there anyway of extending the +10 to -10 range so that it goes lower than -10, maybe with a global adjustment in debug mode to more it downwards?

For those camera club types out there, I am pleased to say that I was successful in my MPAGB on Sunday.

Right, here's what happened.

Sent K5 + lens to JPS, they said camera was fine lens was faulty.

Sent lens to Intro2020 who then asked for the camera body as well, they sent it off to Germany, did god knows what to the lens, and now it's supersharp, even sharper than it has ever been. So a big thank you to Intro2020

In the meantime I purchased Sigma 30/1.4. I did the fine focus adjustment and it needs -10 to get it anywhere near sharp wide open, so would it get any sharper if you could set to greater than -10?
I am loath to send camera and lens off to Sigma in case they muck up the settings for the Tamron 17-50/2.8>
Can I just send the lens off for adjustment?

I agree Smeggy, at 1.4 my model is unlikely to be at the edge of the image. Very tempting at that price for those extra 2 stops.

17-50 packed and ready to send, thank Mike.

Thanks for all the advice guys, lots to think about!

The 30 1.4 is tempting. I know it's supposed to be soft around the edges wide open, but I often soften the edges anyway.
