why you say this lens does not have AF capabilities?

I don't know who said the EF 15/2.8 fisheye doesn't AF, but it does (unless a used/defective lens is being sold).

OK it's just a lens and it's fixed at f:8 so unless you're shooting at a very high ISO it's not going to work in low light. Also it's not the clearest lens in the world....

Linda, D40 body does not have built in AF motor -AF is possible only with the lenses having AF motor built in. . Please check if Tamron you mentioned has a built in AF motor.

N8TE - Thanks for the advice. I will look into the AF-S (especially the 70-300 VR) but it's good to know my old lens is still an option.

Don't know. I have a full frame Nikon D600 and it works fine, including AF. In fact this is my favorite "on the street" lens. It's fast enough for me too.

I have a Fotodiox (Nikon-EOS) I owned a Canon 300D EOS. This worked for me with my Nikon Lens. No AF of course.

OK, let me preface my answer by noting that I rarely use my cameras for video. I have just tried a test video and it looks like it does autofocus with the 18-55 mm lens that comes with it. How it does with other EF lenses, I don't know, but since AF is built into the adapter, I would assume the same.

Hi NJ. This is not normal. I used a Sony A 55 with the same lens. check 2 things. 1. the Camera Body should have the Manual Focus activated. if you activate the Autofocus in the camera body, then it will supercede your lens settings. 2. the Tokina lens is a little different in terms of physically changing the focus mode. There is no AF/MF switch. you have to hold the focal ring and pull it in front or back and it will lock the AF or MF mode. let me know if this helps.

this lens does not have an adjustable zoom. What u c is what u get. Better 4 still shots. Focusing is another issue. on a moving subject u would want to use A I Servo mode while holding shutter button 1/2 way down then fully down to snap pic. Im not fully exper with this lens but i believe it would b difficult to to obtain non blurry pic if not exper'd. With practice I SUPPOSE ONE COULD MAKE IT WORK. Just my opion

There is no electronic communication between the lens and camera. So, the AF will not work. There is no such an adapter will allow Nikon Lens work with MFT exit yet.

Then lens is not image stabilized; I don't own a Canon EOS 50D, so cannot authoritatively address the second question.

it's kind of pointless to AF fine tune with a zoom, since AF fine tune works best with single focal lengths. with AFFT, you can only set focus for one focal length, i.e., if you tweak it to work at 17mm, you'll be off at 50mm. you might have to send the camera and the lens in to to Sigma to have them perfectly calibrated.

doesn't AF with D3200, yes AF with D7100. the cameraneeds to have the af motor built in. D3200 doesn't have that. D7100 does.

Often times Fuji AF system frustrates me. I hear that XF35mm lens performance might feel better with X-T1 but with my X-E1 your description is really familiar to me. When it happens, I put it in manual focus mode which makes a great photo.

doesn't AF with D3200, yes AF with D7100. the camera needs to have the af motor built in. D3200 doesn't have that. D7100 does.

It works good at a macro but because it is a zoom with AF, it can be difficult to use it as a 'true' macro lens. I prefer to use this for wildlife and landscapes but I have used it for macro. Use the MF if going to use for macro. I hope this makes sense.
