Did you look at the Lens Rental MTFs? The Sony is better than the Canon at 70mm. Ten samples tested.

It is?

Do you have a problem with Lens Rentals' MTF curves?

Do you have problem with actual images?

I'd take ten samples tested on an optical bench over tripod shots from one lens any day of the week. Not sure why you wouldn't?

I would take real images any time.

Jacs I feel you are arguing with me for personal reasons or for the sake of arguing.

If you prefer tripod shots fine, but the kind of optical bench testing Lens Rentals does is far more reliable than test chart shots and should be a first resort if they have the data available.

No, they are not. Those tests are not photos. I can list many reasons why those measurements may not translate to sharper images but my point was very different. What I linked does not confirm your statement. It was a question, meant to show that things are not so clear. The Sony looks worse, not even equal, and you claim that it must be better.

BTW, I hope that I will be forgiven for mentioning DXOmark but they show the Canon being  slightly better on the 5DSR and slightly worse on the 1DS3 in the very center but worse overall even on the 1DS3. Also, the Sony shows strong astigmatism. All that at 70mm, f/2.8.
