Uncle Rog at LR takes the 5DS rigs through their paces

Roger Cicala didn't wait long -- he just published imatest numbers for 3 high quality lenses and 1 average lens on the 5D3 vs. 5DS vs. 5DSr:

Short answer: a rising tide lifts all boats. The lens doesn't need to be mind-blowingly good to benefit from the added resolution of the sensor in the center of the frame, but the average lens didn't resolve much better in the corners on the new rigs (which we might expect).

Anyway, give it a look when you have a moment.

Thanks, as usual, he presents interesting data. As he said, it will be months before enough testing is done to firmly establish the characteristics of different lenses.

It just occurred to me what a mess the 5DS rigs represent to LensTip, PhotoZone, etc. They have had 'reference' cameras to shoot for all their lens testing in the fairly consistent 21-22 MP range (1Ds III, 5D2, 5D3, etc.) for many years now.

But I presume now that they'll have to retest everything they have so people can compare two lenses on that 50 MP sensor.

Sadly, this is one area where I can't poop on DXO. They actually roll up their sleeves and do a lot of this already -- their terrible metrics notwithstanding...

For small testers, its a matter of money. They borrowed many of the lenses used to test and will not be able to test the same physical lens. Even DXO says they rent lenses to test. If the test is not done on the same physical lens, the results may not mean as much.

Then, there is the not so small matter of priorities. If the lenses are not in the hands of a large number of photographers, then the money may be needed elsewhere.

Lens rentals is able to test large numbers of lenses, so they average out. Others may not be able to do this.
