Nice fit, works with my gear!
on June 9, 2012
After going into the Menu->Setup->Release w/o Lens->Enable on my Nex-5N I was able to use all my Canon lenses on it. When using this adapter you must manually focus, so I also went into Menu->Setup->Peaking Level->Med and now I can easily focus the lenses on the fly while recording video. Another great feature of the Nex-5N (possibly all NEXs) is that it replaces Button B with the MF Zoom function when using the adapter, making it fairly easy to get critical focus for stills, where I can squeeze out even more details on the eyes then I can with just focus peaking.
Canon's cropped lenses are made for a 1.6x crop instead of a 1.5x like Sony, so there is a chance you will get vignetting when using EF-S lenses, but on both my cropped lenses the EF-S 10-22 and the Sigma 30mm 1.4 I didn't notice any more vignetting then normal (maybe at 10mm there was a tiny bit of darkening at the corners, but well within fixable levels for Lightroom). Canon EOS/EF lenses do not have aperture rings so all your lenses will be wide open. For me this isn't really a problem, since I'm mostly using my Canon lenses for the 1.4 and 2.8 apertures that are not as common in the E system. The one exception is that I almost always want to stop down the 100mm macro lens, and occasionally the 30mm 1.4 down to f/2. So to use this adapter, you need to put the lens on a Canon body in AV or M mode and set the aperture to the desired opening, press and hold the DOF preview button, while you remove the lens (also while the camera is still on). It's a bit of a contortionist act, but it works well and the lens'aperture just pops back into place when you put it back on the Canon. If you need a lot of aperture control, you can get adapters with an inline iris, but they didn't appeal to me since it can cause it's own vignetting and won't work with EF-S lenses. The other option is a four hundred dollar adapter by Metabones, which offers full and automatic (from the Sony body) aperture control, support for image stabilizers and exif data. The problem with that other than the cost and that it's still manual focus and it's almost never in stock.
+ Fits well to the camera and the lens
+ Works perfectly
+ Sony Nex camera have a lot of aids (peaking and zoom) for manual focus
+ Lets me use my 10mm and the rotating screen to get sweeping interiors from the corners of a room.
+ Lets me use my 30mm 1.4 and 28-75 2.8 lens to take really low light photos and great portraits.
+ Keeps me from buying another macro lens, which I don't use enough as it is.
CONS (more like known limitations):
- Must change menu settings before using it.
- Can not control aperture (aperture can be set and locked in from a Canon Camera, but it's an ordeal).
- Canon lenses are much bigger and will block the flash.
- Does not support Canon IS and Sony NEXs do not have sensor stabilization like Alphas do, so my long canon lenses don't benefit as much from this lens other than maybe for fixed tripod video.
