Question: hi is this lens compatble with sony nex 7
Document: Very sharp and fast. I love this prime lens on my lovable Nex 7. It is well made and compact.
-1/2 star because this is an understandable and common issue, but that doesn't mean I have to like it.Only other downside is that it doesn't yet support hybrid AF on the nex 6. Seems strange to release a hot new camera followed by an exciting new lens that doesn't support one of the best new features of said camera! -1/2 star (only a half because I suspect Sony will fix this with a firmware update).For a normal walk around I am loving it.
Let me preface my review by noting that I have 2 bodies to use, both Sonys, both from the same series - the NEX 7 and that a3000 (which uses the same lenses). I am not a pro, and don't use lightroom. I have shot in raw, but prefer to take advantage of the camera's processing (which is useful to reduce chromatic abberations).Also, I only consider this for Sony cameras. If you want to use on a different camera (why?)
I have recently got the lens and have just started to use it on my new Nex 6. I have not gotten to where I can use P, A, S & M settings yet due to complexity of Nex 6's menus but in using auto settings,  resolution and colors looks fairly good. Will give more complete review later. Lens is light but seems well built.
At F2.8 it's very good especially in the center and at F4 it's really excellent and sharp across the frame.Focusing seems about as good as it is with other nex lenses: a bit faster than 50mm and slower than 24mm.
I got this lens with a hunger for a good prime for my NEX-7.
I have the 55mm 1.8 for my NEX 7 and wanted a more versatile lens but with the same image quality.This lens is great, compact and was everything I was looking for.
It really takes good photos for not being a Zeiss model on my NEX-7. With that being said it, to get the full worth out of this lens you must enable the auto-correction settings in the NEX cameras. At 450 bucks, it is about 100 overpriced.
If you are familiar with Sony's SEL 50 1.8 then this lens is just as good in all aspects. Sharpness, clarity, and built in stabilization make it an exceptional value even at a price that some find high. In lenses you get what you pay for generally and this is no exception. I find myself leaving it on my NEX 7 all the time.
If you bought a NEX-7 like I did and want a lens to replace the kit 18-55, this is one of the best candidates. F1.8 makes it really fast, and also creates very nice bokeh. There are other reviews from more intelligent users that compare this with other lenses, go into technical details etc. I don't have all the knowledge.
Answer: Yes.  It's an E-Mount Lens.
