Very disappointing.

Ouch. But I'm still eager to see how the 24 fares...

The center resolutions is not bad ! At f5.6 you actually have corner resolution <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='Smile' />

It seems to me that this is not only a problem of this particular lens but that the entire lens mount is flawed because of the very small flange back distance.

Then why can you get better results with a 5N? They just need to take care with the sensor design, and things work out ok. The short flange distance is a plus, it keeps the camera body compact, wider angle lenses compact and offers a lot of possibilities adapting different mounts including M39 screw mount and M-mount.

At the end of the day Sony can always choose to keep a bigger distance. That's merely a design question.



The current problem is that they've got only cheap lenses for a sensor which require lenses capable of delivering the double performance of a full format camera of similar megapixels. This is simply over the top. Plus the sensor characteristic.

Thank you for this review, and especially many thanks for including information on the performance of the ultra-wide converter (which has rarely been discussed elsewhere, as far as I can tell).



I understand most people are disappointed in this lens, but I would like to ask whether there are in fact any alternatives in the same price range. More generally, does there exist ANY lens that covers 12-14mm focal length for ANY camera with APS-C sized sensor on the market at a comparable price? Remember that the 16mm lens and the ultra-wide converter will add up to little more than $300.



The only half-decent ultra-wideangle lenses that I can find online are the Tokina 12-24 f/4 (starting around $450) and maybe the Samyang/Rokinon 14 f/2.8 ($400, haven't read reviews of that one yet). Neither of these are available for mirrorless systems (except the Rokinon for Samsung NX). Moreover, both are very large. Then there are also Sigma 10-20 and Tamron 10-24 (and 12-24), but it seems their optical performance is clearly worse than the tiny Sony E 16 f/2.8.



So in sum, this lens may be a poor fit for the NEX-7, but with the ultra-wide converter it seems like a bargain option to cover the 12mm focal length for photographers who don't want to spend more than a few hundred dollars on such a specialty lens.



So despite the negative conclusion of this review, based on its lab results it seems to me that it may be a good and fantastically affordable complement for NEX (3/C3/5/5N) owners who may own the 18-55 or an 18-200 by Sony or Tamron and want to go wider.



I understand the disappointment in this lens, but it seems that it occupies a bargain niche makes it a very attractive purchase for some shooters. Therefore I don't understand why this lens seems to be so widely despised.



Again, thank you for going to the trouble of revising this review and including the ultra-wide converter.

Well, we tested the lens on 14mp with better results. The criticism applies primarily to the use on the NEX 7.



You can of course argue that an option is better than none. However, you can always move to a different system. As of now you could hardly argue that the existing lenses are holding you back.

Is it the same sample as last time? When I look at the boarders and extreme boarders, apart from the boarders at f/2.8 and f/4 you get roughly the same figures (within about 100 lines) on both cameras. Makes me question whether you hit some lens limit here. There is clearly something different between the two fore wide open boarders.
