If you are using the reverse mount, you are mounting the lens backwards. This means there will be no electric connections to the camera. You must set your lens to manual and adjust the focus and exposure manually, otherwise it will not work. Which lens are you using? Did you attach the ring to the front of the lens glass or the cameras lens mount?

d3100 doesn't support auto-exposure bracketing, which makes HDR photography a nightmare. Even the t3 supports it ... not sure what nikon was thinking except to keep some features for their higher end cameras.

I also have this slow focus problem on my D300 and D700. Slower focusing than any other lens I have used. Anyone heard about a fix for this yet?

I had the same problem and I found a fix on a different site, so I thought I'd put it up here, too. It seems the "access" message happens because the lens doesn't open all the way; not sure why that is. However, when my camera opens and says "access," all I have to do is get it all the way out. So: very VERY GENTLY pull on the end of the lens (away from the camera body). You can't even feel it move, really, but then it starts working again! Hope this helps.

I haven't gotten mine yet, but I ordered it. I think I read that the silver ring on the front of the lense is how you adjust the focus...give it a try! If it doesn't work, contact the seller or something.

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

I just got this lens and cannot figure out how to adjust the aperture... I can only take photos in f/22 otherwise it tells me to "lock lens aperture ring at minimum aperture" even if I put it in M (manual) mode. How do I change it so the aperture is adjustable and not fixed?

This information was super helpful. I had the exact same question. I tried, several times, contacting the seller with no luck. I never thought to contact Nikon. Please share if ever you find a good, inexpensive, wireless remote for the D3100. Thanks!!

You need to have an adaptor to your particular camera. Mine is a t-mount. These are little rings that do not cost much. I have used this with a Nikon. It is strictly manual focus, but fun to play with until you can afford something better.

Mine does the same thing. Not pleased with it at all. It will also come loose form the lens real easy. It just won't stay tightened. Don't know what else to buy. I just quit using it on my tripod. Wouldn't recommend this at all, I give it a 00000000!!

Do you have your camera set to auto? The camera needs to be set to a manual setting. On my Nikon, I have an M (manual) setting next the the auto, landscape, etc... Double check which setting you have it on.You have to do some of the focusing on the telescope, too. The same way you would focus without the camera is how you would focus your camera. We had to look all of this up, too.

My camera wasn't grey market. It was Nikon USA. Still having troubles with viewfinder focus. Camera is being repaired for the 3rd time. I have a feeling it still won't work properly.

I believe all i had to do to get it to work was (on my nex6):-Enter the main menu screen-go to the 'setup' section-Scroll down to 'Release w/o Lens'-Set 'Release w/o Lens' to 'enable'Your camera will never recognise the lens as its a 3rd party-un-powered-manual lens so you have to enable the camera to operate like normal without a lens attached. If the shutter activates without a lens attached then you are good to go.Hope this helps. BB

I have the same problem and mine miss focuses too. I have contacted Nikon, but I'm still waiting for a reply. I'm curious if this lens is a waste of money? Did you guys ever find out what was wrong?

I used on my d5200. It did not function as i expected. Maybe because i am a new user and dont know how to properly adjust it. I will buy a nikon just for sure to replace that one.

I had the same problem with my D3100. I consulted the manual, all menus, I went online for tech service, and spoke to other Nikon users. It just boiled down the incompatibility issues with my specific model. I was told very cautiously that non-Nikon remotes very much have the ability to ruin the motors inside the lenses. Since lenses are the most important and expensive component of the camera (already an investment), I sent mine back and will by trying the Nikon remote in the near future. Since the description stated that it will work but however does not, shipping (up to $5.26) is refunded. Good Luck. I had the same problem with my D3100.

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!
