Since Brian's comment about pixel peeping with the A7R2 and FE 100/400 combo in my Crop post I thought I'd crop properly to really pixel peep.
Same old subjects I'm afraid but the original is 4000+ pixels



And this is a 957 pix crop in DxO. Didn't do any noise reduction.



And while I'm here a couple more just showing the difference between F8 and F10. The above was at F10. @400mm. iso 1600. 1/400sec.

Next is a different bird at F8.400mm iso 1000 1/400sec. I often like a shallow DOF in this case to emphasise the head more



But here it fails I think because the beak is OOF.

Say Aaaah

Not a very good lens at all is it?

You should explain why f/10. It might seem an odd choice since you are theoretically putting the phase detect system out of action. Or does it? Anyway, not a problem in that light I guess?

That was a quick comment Paul, I was just about to turn my PC off.
When I saw #4 was OOF I decided to try F10.for a little more DOF. Actually the light was very poor, in fact it was drizzling and all the above were taken with a flash. Not only was I testing a new lens I was also weather testing this combo The full frontals don't show the eyes enough so here's a side view where you can see the reflection. Don't know what happened to Flickr but you used to be able to click on the shot to go there and get the full EXIF details??

Say aaaah too [or two!]

P.S.I should have added I usually use center or flexible spot focussing and center metering in this sort of situation

Thanks for indulging me with a series of startlingly good crops with the A7rii + SEL100400GM. The only down side... if I don't get similar results, I'll know it was me

Cheers... Brian

P.S. with reference to #2, you should seriously think about providing napkins the your subjects before they pose.

I blame sample variation--somehow all the lenses I ended up with are the worst possible samples of their type ever made.

Yes Brian they're certainly very messy and noisy eaters, they have a habit of flicking their heads sharply to the side sending food in all directions.

Jerry. Although a tongue in cheek comment it does make me wonder. I was once told by someone who had visited a Sony lens manufacturing/product line that the top of the range lenses were all tested for image quality. This was some time ago and he was referring to the A-mount primes like the 500mm and 300mm F2.8. It would be interesting to know the current situation, ie at what point specific lenses cease to be tested. I like to think for example that all the G masters are, so that theoretically there's no such thing as a bad copy. Of course buying second hand's another story.
