Review Sharpness : Sigma 40mm 1.4 @ 1.4 - Tamron 85mm 1.8 @1.8 - Canon TS-E 90mm Macro 2.8 @2.8

[Fixer]

So I just received my Tamron 85mm f1.8 vibration control autofocus today and I just had to do a sharpness looksee . . . settings don't matter, just the sharpness at widest aperture under (E)TTL flash was the looksee . . . And wow - as far as I am concerned at 100% they are all as good as each other as far as totally acceptable sharpness goes !!!
A 100% image sharpness comparison using (E)TTL flash with everything at the same distance. ISO 100 : What do you think ?! . . .

I would be looking into the corners.... and something far more detailed than a few big and thick lines; and do it with 5Ds or R5

Having said that I do expect all three to perform well.
