Will the sigma lens's auto focus work on my Nikon 5100?

Yes. It is a great lens, with your D5100 cropped dx sensor, this lens will be the equivalent to a 105mm - 300mm. Be certain to order with the nikon mount version.

The entire functionality should work on a 5100. It worked on my D100, which is WAYYYYY older than your 5100.

Nikon and Pentax mounts do not have an aperture ring. Some functions may not work depending on the camera model.

You are calibrating the camera not the lens itself... The camera body reads the serial number of the lens and apply's the bias or correction to the focus system of the body... So if you are looking at another camera body make sure it does infact have the feature... I am not sure if the 5100 has that feature... I know my D90 does not...

I believe that any newer nikon lenses that have the AF-S designation will work with the D5100. It is my understanding that the D5100 camera body cannot focus the lense itself so it relies on autofocusing lenses (AF-S) to get this done. You may want to investigate this further though.

Sorry, my earlier answer was incorrect. Your 5100 does NOT have an internal focusing motor (like my D7000) and therefore will NOT autofocus with this Tokina 35mm f/2.8 Macro.

I think so but you may need a T2 to Nikon mount adaptor. It is a manual lens and no need to have any electronic interface. So, once you mount to the camera it should work.However, I do not own a D5100 and can't experiment with it. Some camera (like Panasonic M43 models) DO NOT work without lens by default. For these camera, you should enable working without lens option in order to use manual lens.

I am not sure. I have the 5100. See if your lens will fit the 5100 then you are good.I am thinking you are good but I would check to see what others tell you.....steve

Tom, I shoot a D90 but I've heard this version of the lens works fine on a D5100. Good luck!

Yes, the auto focus works perfectly. My D5100 is the best cam sin the old slr days that I still own. I would have the cam checked out for a malfunction if yours is not working. Take care and good luck with a great camera.

No, That lens requires a motor in the body to AF, so it won't AF with a D5100.

The adapter I got only allows the lens to fit on the canon, but autofocus does not work. I don't have a sigma lens, so I'm not sure whether yours would autofocus.

No, it will not. It works just with a limited number of SIGMA lens. Have a look on the SIGMA website. It does not work with any lens of different company (Nikon, Canon, Pentax ecc.). Better: it can increase magnitude of 1.4 but you will loose both autofocus and automatic exposure. Frankly speaking, I use it (not frequently) together SIGMA 300 mm f: 2.8. The autofocus is not very precise, slow and the quality of the photos is not fantastic considering the whole amount of money that the lens (both) costed. Regards

I'm not for sure you may want to ask nikon. But I dont think so. It has a plug in wire for the automatic focus and I'm not sure your lens has the same plug

This should work with your camera..I have a friend who has a D5100 and uses another Tamron lens for his camera..it works on my D50...

It should work fine as a manual focus lens. The auto focus feature will not function on a 5100.

This lens will auto focus on both the D5100 and the D3100. Look for the AF-S desgination in the description of the lens to determine if it will auto focus.

Yes it works with D5100. Autofocus works well in good light. I stop shooting an hour before sunset and when it gets very cloudy.
