Question: Will my e-mount lenses for my nex5 and alpha 6000 fit this camera?  And is there a cropped image?
Document: And the main front and back dials can be swapped between aperture and shutter speed. The rear click wheel is customizable, but I think the default of ISO is the best.LENSES &#8211; NON-SONY: The wonderful thing about the mirrorless camera is that the film plane is much closer to the lens mount than the SLRs. This means that you can fit an adapter in there and run old SLR lenses exactly how they were meant to be (i.e. the distance to the sensor is the same as the lens makers designed the lens for).
I returned that lens and got the Tamron 18-200 diIII lens. The in-lens stabilization is NOT disabled here. Image quality is NOT perfect nor tack sharp at 100% magnification. It is good at normal magnification. It is not very good indoors as it has slower glass. It does a good; although not perfect; job outdoors. I would recommend this solution while we wait for a full frame e-mount solution from Sony. The Tamron lens is about the same size as the FE24-70 kit lens that came with the camera;  so it is very good from a portable standard.
I think they were a little lazy in the design. Looks like an alpha lens stuck on a nex (there is no nex vs alpha, but this is obviously a nex mount). There is almost a 1" shim space between the mount and rear element. Lecia has short/ compact lenses on their camera, this a milc too. There are lens distortion with this kit lens, so I turn on the lens correction in Lightroom.+ Like Nikon, I can use aps-c  lens on a full frame.
I did buy this camera for the lightness and compactness, after all, and slapping an all-metal DSLR lens on the front kind of negates that benefit.A lot of people are currently testing the gamut of legacy lenses on this camera with more rigor than I have; you can find links to those tests on the Sony Alpha rumors website or do Google and Flickr searches if you're curious about how a particular lens plays with this camera. For my part, I'm both excited and financially terrified at the prospect of getting more M-mount lenses to use with the A7.
It's easy to carry with me, I get pro results, it's rock solid, ultra configurable to the way I want to shoot, etc. We're having fun now.UPDATE: I was so impressed with the leap in IQ from the Alpha A-mount lenses that I purchased the LA-EA4 adaptor. This is the adaptor you want ... fast AF and actually much smaller looking and feeling than what the pictures of it on the camera would seem to indicate. If fact, I am so impressed by the auto focusing response and lightness of the unit that I decided to simply make the A-mounts my lens collection.
It can take virtually any lens. ANY LENS! It can AF (and auto aperture) with any Sony, Minolta, and many Canon autofocus lenses. That's A mount, E mount, FE mount, and EF mount. Wowzers! As with most mirrorless bodies, you can forgo autofocus and aperture and mount many more lenses, so that opens up the rest of the lenses out there. The fact that full frame lenses keep their relative focal lengths is a huge plus, and lenses designed for cropped sensors still benefit from a 10MP cropped mode (which you can override--another plus).
Focus is also accurate and quick.Conclusion:  If you need perfect quality get a Zeiss prime lens. If you need portability and are willing to sacrifice a little quality the Tamron 18-200 diIII lens is a good choice while we wait for another Sony alternative. I do NOT know why Sony has disabled OSS in most of their e-mount in-lens stabilizated lenses when mounted on an A7, but Sony has. Sony has confirmed this with an e-mail to me.
By the time I got focus, the deer would be gone into the trees.3. Use Sony E-mount lenses. Here I have to deal with the crop factor (images are 3936x2624 pixels; plenty for my purposes). I decided to sacrifice a little quality for travel convenience. First I tried the Sony 18-200 LE lens. Sony has disabled the in-lens stabilization in this lens and have done this for almost all for their e-mount lens when used on an A7! This is not good for shooting hand held at 200mm.
I didn't find this a problem for the most part as it does shoot well in low light situations but chances are you will need to get one sooner or later. The Sony HVLF20M external flash comes in at around the $150 mark.Sony is investing heavily in its e-mount adapter and as such all the new cameras Sony has recently announced take e-mount lenses including the A7 series. There are two types of E-mount lenses, the older NEX style which are APS-C and the newer FE full frame E-mount lenses.
It is too large to appeal to pocketcam fans, way too expensive to match the super-zoom bridge cameras on price, about 3X as expensive as popular enthusiast DSLR's with kit lenses and all-around lacks almost everything a pro photographer looks for, particularly ruggedness and easy access to a wide variety of industry-standard lens mounts and other accessories. Yet it is being cited time and again as one of the most exciting cameras of the era and for good reason. My assessment (backed by Sony) is that the A7 is directed at someone who is serious about image quality and willing to give up things like fast burst shooting, ultra-fast auto focusing, i.e.
Answer: Yes the nex5 lenses will fit the camera but the image quality will be lower. I have the E PZ 16-50mm F3.5-5.6  Zoom Lens and it works good with the A7, but the IQ is not the same. The Sony a7 is a full frame camera, and the nex lenses are not full frame. To get better pictures it´s better to get full frame lenses.
