Received a Rokinon 8mm F2.8 Ultra Wide Angle Lens for a NEX7 getting message "cannot recognize lens, attach it properly". Why?

You need to tell the camera to operate without detecting a normal e mount lens. This is a setting called "Shutter release without Lens" or something close to that under setup.

There are no electronics in the lens. The camera has to be in manual or aperture mode to work, but it will work.

I have the same problem. I just received Canon lens adapter for Canon S3IS. It doesn't fit. There isn't any way to attach it.

Hey Donna......we had the same problem so returned it. My husband ordered a Nikon lense and has encouraged others not to buy other brands. They just dont work on the Nikon. Hope this helps.

I use this adapter on my NEX7 with a Minolta 50mm 1.4 and it works great. The problem is the camera doesn't recognize that a lens is attached. There is a setting to override this. On the NEX5n I don't know where it is, but it is there. Have fun.

It does not work with My nex7 either. It is probably deffective, perhaps out of sync.

I couldn't get a response from anyone on this topic so I just went ahead and bought the sel55210 lens a couple weeks ago. Like you said, it attaches with no problems, however, with my nex-3 it seems to work just fine. I can't say that I have used the camera all that much with the new lens so there could be some subtle problems that I haven't encountered yet but mine definitely does take pictures. It also doesn't seem to have any problems using any of the default shoot modes and it auto focuses just fine. Have you tried updating your camera's software? There might be something with the initial release of the software that doesn't allow this lens to work.

I own a Sony NEX-5R and in the setup menu you have to go to "release w/o lens" and it must be set to 'enable'. That's how I got my adapter to work even though I don't own one like the version pictured. Good luck!

thats wierd, it shouldn be tha way... depends what you are mounting i think, ive used it with the BMCC and rokinon lenses no problem... maybe check your setpup

You must look at the thread size of your lens and not just what lens it is. These are two different things.

First, there's a little pin you need to push to release it. Second, Nikon lenses release in the opposite direction from Canon lenses so make sure you are turning it in the correct direction.

Also, there two levers on the back of the lens. One needs to be engaged by a pin in the adapter. I wonder if the the lens is turned enough. There's a "Lock/Unlock" collar too. Maybe that's in "Lock", and the lens isn't really on all the way?

What do you mean by it doesn't recognize? If you're talking about the aperture control auto focus etc its normal because its a manual lens everything is controled on the lens. dont forget you have to enable the feature "release without Lens" otherwise you can take pictures :)Hope it helps

Dear customer:This lens attaches to the camera body, not the existing lens.

I believe this was sold as a fixed mount lens, not an Adaptall II lens, and it came in a Nikon mount. If you don't mind my asking, why do you need to use an adapter, are you trying to remove its fixed mount and convert it from another brand of mount to Nikon?

I'm sorry that I can't give a reliable answer. I called Sony about it while I had the lens in my possession and was told that it didn't apply to my NEX-7. Sony Customer service was quite helpful. I suggest trying them. Unless there is new stock at Amazon, my understanding is that you will likely have to send the lens to Sony for upgrade if yours is not the NEX-7 model.

I have the same problem with the exact camera and fisheye lens. I still don't have a solution for my problem, I can't even get it to fit.

you might want to check the specs for these lenses vs your camera. I also like to suggest you might want to contact the seller's technical support. sorry I couldn't help.
