As I told you Sony is working on two new FF models, one with 24 and one with 36 Megapixel sensor. With the recent release Canon opted for a “low” resolution 22 Megapixel sensor while Nikon opted for the Sony 36 Megapixel sensor. Question is, how much difference will it make in the real world? Roger from Lensrentals (Click here) made a comparison by testing the same Zeiss 25mm f/2.0 and 100mm f/2.0 lenses on both cameras. There are some interesting findings:
1) The difference becomes clearly visible when using the best performing lens aperture. At full wide aperture the difference is almost zero.
2) You need super quality glass to get out the most from the D800. Interesting, the Zeiss lenses are slightly superior to the tested Nikon lenses.

Sony’s strategy to offer two different FF models is welcome but there is also a secret weapon Sony has to push. The Zeiss lenses. It seems they can give the A-mount camera the edge in terms of resolution over Nikon and Canon lenses. I hope the rumored A mount 50mm f/1.4 Zeiss SSM lens will arrive along the next FF camera!

P.S.: Nikon D800 rules the DSLR ranking (Click here) while Sony rules the mirrorless ranking (Click here). Looks liek Sony sensor and camera business is doing great!

THe US store BHphoto (Click here) expects to ship the new A57 on April 22. Meantime new tests have been published: ISO test at DCfever (Click here). A57 image samples at Lenstip (Click here). First impressions at DxOmark (Click here). Sony Alpha A57 at each ISO setting at ThePictureDesk (Click here).

The next new SLT camera should be the A37. And than the A99…

Klaus from Photozone has some bad news for us. He tested three NEX lenses and all are delivering sub average results when used on the NEX-7. The 24 Megapixel sensors demands high quality lenses and the cheaper 16mm, 18-55mm and 30mm macro can’t exploit the full sensor potential. The only exception is the [shoplink 8448]50mm f/1.8[/shoplink] lens and very likely the still to be tested and wonderful [shoplink 8450]Zeiss 24mm f/1.8[/shoplink]. Here are the latest three tests from Klaus:

1) The Sony E 18-55mm f/3.5-5.6 OSS (Click here to read the review) kit lens isn’t good enough for the NEX-7: “it may perform decently on lower resolution NEX cameras (the 3 and 5 series). However, its capabilities are clearly overstrained on Sony’s 24 megapixel sensor. In so far it is very surprising that Sony is also offering it bundled with the NEX 7.”

2) The 16mm f/2.8 pancake (Click here to read the review): “the Sony E 16mm f/2.8 may be a controversial lens on lower resolution NEX cameras. However, it seems rather pointless to use it on the NEX 7 – 24 megapixel are way beyond the capabilities of this tiny lens.”

3) Klaus also tested the A-mount Zeiss 85mm Planar lens on the NEX-7 (Click here to read the review) and while it definitely performs much better there are still some issues: “even the mighty Zeiss isn’t perfect anymore on the 24 megapixel sensor. At max. aperture the center performance is certainly very good but the border quality is a bit lower than expected. This is somewhat surprising considering the fairly big lens to sensor distance due to the required adapter. The decrease in border quality either relates to a difficult sensor characteristic or, possibly, to a sub-optimal sample of the lens.”

All these lenses do deliver a better performance on other NEX cameras with lower resolution sensors like the [shoplink 8452]Sony NEX-5n[/shoplink]. This is a call for Sony to focus on the development and release of good quality lenses! The NEX-7 remains a top seller surpassing the direct competition like the Fuji X PRO 1 and Olympus E-M5 at Amazon US (place 2), Amazon Germany (place 8), Amazon France (place 4) and Amazon UK (place 17). And they would sell ton of lenses if there would be more of them.
