Re: You quoted that review out of context

The lens struggled to be particularly sharp on a 10MP sensor.  It needs to be stopped down to f/8.  It would do even worse on a 16MP sensor.  The A lens is extremely sharp wide-open.  Pretty cut-and-dry situation.  The voigtlander simply isn't in the same class as the A's lens.

The poor performance you reference occurred outside the DX crop area on Full Frame images,  The same report you quoted actually stated that on an APS-C sensor, it was good across the frame at f5.6, which is only stopped down 1-1/3 stops - rather typical actually.

And from what I've heard, the Nikon A's lens is nothing special in the corners at f2.8 or f4 either.

See here for reference:

"Coolpix A edge resolution very low at F2.8 and F4?

http://www.pcmag.com/article2/0,2817,2417565,00.asp "

So maybe you'd like to try again, since your last "proof" seems to have been a whiff.

"Good", no, it stated "fairly decent results" a f/5.6.  Look at the crop results and the verbage.

"While not particularly sharp at f/3.5, the images taken with the APS-C body did produce higher MTF50 numbers then on either of the full frame bodies used in the tests."

As you can see, stopping it down on a 10MP XTi barely improves it.  So, no, it is not ideal for a crop 16MP sensor where it would perform even more poorly than it did in their testing.  They warned about it in the review.  I'll trust a proper review site over "pcmag" anyday, and DPR and DXOmark both show very very good corner performance from the coolpix at f/4.
