Using the Zeiss Biogon ZM 35mm f/2.0 on a NEX camera.


Introduction:
Here is the next article about one of my possible future lens purchases. Generally what I am looking for are lenses with a high build quality (hate plastic lenses) and that are not too big. The NEX-5n isn’t exactly the ideal camera for big lenses. But what I also want is a lens that can cover a full frame sensor as I believe that we will not have to wait a long time until Sony releases a sort of full frame NEX camera. Unlike digital camera I feel very comfortable to spend my money on a good lens. Lenses do last forever and keep a reasonable value in time (sometimes they also gain value!). So after taking a look at the superb Zeiss Sonnar 50mm f/1.5 ZM lens (Click here to read the article). I searched and collected some reviews about the Zeiss Biogon ZM 35mm f/2.0 lens (Click here to see it on eBay). Of course this lens will work on a NEX via M to NEX mount adapter (again here on eBay).

Lens reviews on the Leica fullframe camera:
The Zeiss Biogon is a M-mount lens and there are plenty of reviews on the Leica M camera.
Ken Rockwell writes: “This Zeiss 35mm f/2 Biogon ZM is optically superb“. Daniel Valente writes: “I am happy to say that the bokeh is neutral and pleasant“. Diglloyd says: “It’s a no-brainer for any M shooter.” And Steve Huff also likes the lens a lot: “The lens is sharp, it has gorgeous rich color…and if you are one of those who love the 3D qualities of Zeiss then the Biogon will be right up your alley“.

Lens reviews and tests on Sony NEX cameras:
The lens performs extremely well on full frame cameras but how good is it on the Sony APS-C sensor?
The most important review has been made by Photozone: “The Biogon produced impressive quality figures in our lab. The resolution is good+ to very good at f/2 and reaches very good to excellent result beyond till diffraction is limiting the quality from f/11 onwards. Lateral CAs are well controlled and not overly field relevant. The bokeh fringing (LoCAs) is typical for such a fast lens. Distortions are basically absent. The most obvious weakness of the lens is the amount of light fall-off at f/2 which is quite a bit higher than average for a full format lens. The build quality of the Zeiss lens is superb thanks to an all-metal body and super-smooth controls.
Björn Utpott just purchased that lens: “I finally know what my daily NEX-5N kit will look like: the Zeiss Biogon as my main lens with the Sony 16mm pancake in my pocket for the odd time when I need something wider.”
Image samples can be found on flickr made by kriswashington and shigerus.
Video samples can be found on youtube made by dai3smile and unboxing video made by denrusso.
To see how the NEX-5+Biogon combo looks check that picture on flickr. Ad here is the NEX-3+silver Biogon on flickr.

Conclusion:
Super sharp, super build quality and you can use it on any NEX camera (APS-C or FF) that will be available in future. It even works o my old Minolta CLE! This lens looks like a real winner!

Sony NEX-7 sensor gets DxOmarked! It is the Sony camera with the best overall score!

And here we are. The NEX-7 shares the same A77 sensor. But are the results the same? Is the semi transparent mirror taking away some bits of image quality? DxOmark (Click here) tested the NEX-7 image quality and the answer is that the NEX-7 is by a tiny bit better than the A77. De facto it is the Sony camera with the best results to date (even better than the A900 full frame camera).

As you can see form the screenshot on top the NEX-7 has a slightly higher dynamic range an color depth than the A77 (but the difference is negligible). But High ISO results are visible better thna the A77. Only the A900 can beat the High ISO results of the NEX-7. Now imagine what a NEX-9 full frame camera could do :)

P.S.: Check for NEX-7 preorders at: Amazon, B&H, Adorama, J&R, eBay.

Sony NEX-7 versus NEX-5n image quality test at LL.

Luminous Landscape (Click here) updated their NEX-7 rolling review with a new image comparison: “the NEX-7 gives the photographer the choice of higher resolution and larger prints, or comparable resolution and comparable noise characteristics when compared to the NEX-5n, and both are presented at the same size. I should add parenthetically then in real-world photography, when shooting raw and doing a bit of NR in Lightroom, all ISOs up to and including 3200 are completely usable for most any purpose.

And I agree withtheir lats editorial comment: “If you’ll allow, I’ll also make a small editorial comment on the whole question of high ISO noise. In my opinion too many people on brand discussion forums make too big a deal about high ISO noise. I suppose that it’s one of those things that lends itself to easy visual comparison, while topics such as dynamic range, colour gamut and fidelity are more complex, and less easily quantified outside of a lab.

+1!!! ;)

Rolling NEX-7 review at LL. A65 review by ePhotozine.

And Luminous Landscape (Click here) is writing a NEX-7 “rolling review”. It’s a very detailed and incredible useful ongoing test. An absolute MUST-READ!

One more NEX-7 news. I don’t know how reliable this info is but the Expensys website says the NEX-7 will be “Due Thursday 15th December”.

You can read a new complete A65 review at ePhotozine (Click here): “The camera has good battery life, and although there is no optical viewfinder with SLT cameras, the new OLED EVF is simply stunning and makes the view through the camera look excellent. Although it is difficult to show on the web, it would be well worth viewing for yourself if you still have doubts about switching from an optical viewfinder to an electronic viewfinder. Highly Recommended“.

Photographytalk (Click here) explains why the A77 was worty to wait. And there is an interesting “A77 myths and truth – diffraction test” post at Dpreview forum.

Sony NEX-7 presentation at BHphotostore

The video on top has been made at BHphoto store in NYC. Enjoy!

P.S.: Sony will soon release a statement about the A77/NEX-7 production status. I guess the chance is low that we will see both cameras in Stock before Christmas. And only a few store accepting NEX-7 preorders. Check this search links: Amazon, B&H, Adorama, J&R, eBay.
