That's a fantastic pose on both Peter, but the first photoshop photo, is of exquisite proportion any funny

What I need versus what I have

But....... it is not a walkabout lens in my view. It is big and heavy. Take it out on a shoot by all means, but carrying it around all day attached to the camera would not be fun. For that, the 50mm A 1.7 you have, or a FA 50mm 1.4 would be more suitable.
The choice is yours. If you are anything like me you wil buy it anyway, and you will not be disappointed I can assure you
Here are some photos I have taken with the DFA* 50mm 1.4 , the most recent one last week.........

I have done extensive testing on My K1. It suffers with a general BF. I need on average +7 for accurate focus, but on some lenses it requires +5 and on a couple +10 is only just enough.
I can support you if you'd like to try it.
The two lenses that probably need +10.5/+11 I can live with that. For a general scene it is always close enough, for a close up I will be using manual focus anyway, so I do not think it is required.
Should anything change I will give you a shout, and thank you again for the offer.

Looks a very good lens either way.

When only the square can be seen, both A and B appear the same. Or at least that's what my brain does!
They are both the identical shade of grey. Our eyes/brain tell us something different, which is quite fascinating.
It does make you wonder why there is an obsession in some quarters with things like the ultimate in sharpness or perfect white balance, when the brain is going to reprocess what the eyes see.

Are we talking about absolute shades or relative?
The shadow from the green cylinder impacts on 'B' but not 'A'...however on my monitor 'A' is definitely
a darker shade than 'B'...to my eyes allowing for the shadow from cylinder.

This is what you get if you cut the two squares out in photoshop. You can also print the image and use a pair of scissors

It's funny the difference between what you know (B is a white square and A is a grey square) and how your brain processes it. White is white so it has to be lighter
