Hi, I put it in my 18-105mm lens from Nikon D5100. But it is not working well because it can not focus. Is there a way to do?

Hi Bruno, the problem is that the lents Opteka 0.35 only works in lens of 52 - 58 and 67 mm. Here is the description of this lens "Opteka .35x HD Super Wide Angle Macro Fisheye Lens. Direct 52mm mount; Adapters for 58mm & 67mm included." You must have one of this 3 lens to work in your camara, if you dont it doesnt work.

I placed this lens on a Nikon N80 35mm camera and the image jerked a couple of times then began focusing normally. It only happened when I initially attached the lens and first turned the camera on. Not sure if the lens is totally compatible with 35mm. Did you attach it to a 35mm or digital? Did you determine the cause and was the lens not working correctly?

I have the same equipment. The situation you describe is not normal in any lens mounted in any camera. But this combination lens/camera use to do it. Put the lens and the camera on manual focus, because the autofocus in this lens on this camera is a nightmare. But in manual mode, this lens is pristine, wonderful.

Its a macro lens. Try getting as close as posible , you almost have to be touching the object with the lens for it to focus

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.

did not work on D7000. Milky and no focus at all until f11 or so, so it defeated my intention of using it with my old prime lenses.Not saying it won't work on yours ...just didn't work on mine

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.

You have to have a nikon camera with a focusing motor to auto focus with this lense.Make sure the lens is set and locked at f 22. Hope this helps.

I would also like to know if there is a lens for the D40x that is similar to the Nikon AF f1.8. I thought it would be OK to focus this lens myself but it seems in low light I can't see well enough to focus the lens. Now I'm sorry I bought it because I can't use it for what I intended. It does take nice landscape photos but there is no focusing to worry about at infinity.

You have to make some changes on your camera for it to recognize the lens. The photos I took with it came out fuzzy and a lot of noise. It was because you have to use Manual Focus and I am not used to that so possibly why my photos didn't come out.

you can only adjust the aperture on nikon lenses that have the adjustable aperture ring. this adapter passes no lens setting information to the camera itself. Very few, if any, of the adapters can do that and then its usually just focus. Most adapters are strictly for manual mode

It should work just fine. it's 52mm just like all Nikon lenses. Use it in manual focus in plenty of light or flash, and you will have an inexpensive macro lens.

jESSICA, I got an article from Nikonians that affirm it performs auto focus with D--3100/5100/5000/3000/60 and 40. Don't take my word on this and research a bit more, maybe call Sigma and ask them directly. I hope I helped you in some way.

My 18-200 lens from my old D 90 works well, with auto focus working quite well. The auto mode doesn't work but the "P" and other modes are fine

I have a Nikon d3100 and I had a lot of problems setting the f number,you have to try to set it before you take off the lens and attach the tube. poor quality too. my advice? save up and get the ones that can auto focus (around 50 bucks), or buy this and try it out

It works well on my D5100 which is essentially the same. But with no metering and manual focus. Just put the mode to "M" and shoot a test shots until the exposure is right. Takes great pictures, if you remember that it will be a little soft when wide open. It makes a great portrait lens because of the way it isolates the background.

I second guessed myself as well in the beginning. The lens has a pretty long manual throw. i.e. it takes some big turns to get things into focus manually. Keep trying and it should eventually get things into focus.
