Fotasy C Mount to E-Mount Lens Adapter, 16mm Cine Moive Lens Adapter to E Mount, C to E mount, Compatible with Sony NEX-7 a3000 a3500 a5000 a5100 ...

Works great for my 55mm f3.5 micro nikkor on my A7III and A6600. Mostly use it to scan film

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. PROS: + 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.

The adapter works great for me & I completely love it. It allows me to mount Canon EF lenses to my Sony Nex-5 camera, which is exactly what I wanted it for. The build quality of the adapter is better than I expected and should hold up pretty well. It also looks great on the camera. That being said, there are some things to consider with this adapter: - The adapter has no means of using the camera's auto-focusing, so everything must be focused manually, which may or may not be an issue for you. Also, since the Nex cannot actually detect the lens that is attached, it won't automatically zoom in for focusing, you must manually push the MF assist button; MF assist will zoom in on the LCD to show fine focus details, then you must either push the exit button or take the photo while still zoomed in. If you are shooting handheld, this is a little hard to do without physically moving the camera out of focus again while pushing buttons. Focusing without using the MF assist zoom while shooting handheld works for me too. It just depends on what you are shooting, how precise of focus you need, depth of field, etc. However, on a tripod, or other stable surface, it works out perfectly for me. - There is also no means to change the aperature with just the adapter and the Nex camera. This could be a drawback, depending on what types of photos you'll be shooting. I will almost always be using this lens for its 1.8 aperature, so it works for my needs. - While there are things this adapter cannot do, please keep in mind the price. The adapter from Sony (LAEA1) Sony Alpha LAEA1 Mount Adaptor (Black) that attaches Sony A-mount alpha lenses (with auto-focus, aperature, etc.) costs $159.95 on ZeeBooth as of today. So, for the $33 or so that I paid, I am extremely happy. So, my advice is this: if you already own or have access to some nice Canon EF lenses and don't mind using manual focus, don't wait. Buy this adapter now. If you are getting this adapter and expecting to buy a lens or lenses to go with it, consider the drawbacks and determine if it meets your needs & skill level. If you don't want to use manual focus or you need to easily use aperatures other than wide open, this adapter is not for you. I'm posting some photos of the adapter and Canon lens attached to the Nex. I'm not an expert photographer by any means, but I'm also posting a quick shot of a carebear just to give you an example that was shot using the Nex, this adapter, and this great Canon EF lens: Canon EF 50mm f/1.8 II Camera Lens (Which, by the way, I highly recommend the lens, especially for the price) Finally, some tips if you do buy the adapter: 1. You must enable the camera to take pictures even though it doesn't know anything about the lens attached. Do this by going into the menu > setup > release w/o lens > enable. You only have to do this once and can leave the setting on, even with your regular Nex lenses. 2. Use the red line above the "EOS-NEX" wording on the adapter to line up with the lens, just as if you were mounting it to a camera. 3. Test how the release lever works before attaching lenses, just to make your life easier & so you know how it works. It physically pushes down, toward the camera (as if it were mounted).
