Autofocus on D3100 ?

No. Only higher end Nikon's have built in focusing motors in the body, which this lens needs. 3000 series and 5000 series lack this internal motor.

I have a D5100 just set the focus square where you want it and it will focus. The lens must be in auto not manual.

I have no luck in auto focus mode, but if you set it for a regular picture it should be ok.

AutoFocus was fine. Some circumstances, e.g., bird watching, require manual focus.

The lens works fine on my Nikon D3100 camera with one exception; it does not auto-focus (which I know) and I am having trouble getting landscape photos in focus.

It fits on the D3100, and you can take pictures with it; but nothing automatic works with it so it doesn't autofocus, and it doesn't TTL light meter; only CPU lenses work.

Yes but the autofocus won't work because the d3100 doesnt have a build in motor .

Same type. Use it on D90 however lent to friend w D3100 before. They work best on manual focus/apature. You can use auto but usual sensor is hair off due to focal change the tubes cause.

autofocusing will not work, as you do not servo built in your camera. You should look for lenses marked "af-s"...or get D70, D80, D90, D7XXX, or any of hundrets DX00.

I have the same question, actually. That's the only reason I haven't bought it yet. I would love to get myself in shots, as well as the entire family, but the problem I have now with just using the camera's self-timer is that you can't autofocus on yourself when you're behind the camera! The review I read seems to say that you can't autofocus using just the remote...but B. Babb's response makes me think otherwise. I'm sure someone else out there would care to clarify...

Yes my friend, works very fine, with this lens you can shoot like a pro with D3100.

the lens does not allow you to fine focus manually in autofocus mode. you would have to set it to manual focus.

Hi, I have a Nikon d3100 and this thing was so hard to have it work. besides that you have to manually set the F number before you take the lens off to attach the tube. it was a hustle and had poor quality. I ended up getting one that was around 50 bucks,my advice? save up and get the one that can auto focus

It won't autofocus with the D5100. It only autofocuses on cameras that have an internal focus motor.

Here is a chart showing what can be used with the D3100:http://www.nikonians.org/nikon/slr-lens.htmlBasically, you can buy this lens, but you'll need to manually focus. One lense close to the 50mm above, is the 35mm:Nikon 35mm f/1.8G AF-S DX Lens for Nikon Digital SLR CamerasThis one will autofocus with the D3100. Hope this helps.

Yes, it is manual,yes it will be very easy to focus with it. (Basically, you just use the higher f-stop number, and everything is in focus = you do not need to focus it at all).And yes, it will fit D3100.PS. Read more :)

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.
