Does this lens have autofocus?

Yes. It does not have a focus limiter therefore it has to rack all the way through the class focus range even when you are shooting portraits so it tends to feel a bit slower to focus than some other lenses. That aside, it is a fantastically sharp lens across the entire frame.

No it has a manual F-stop. Almost all manual F-stop lenses do not auto focus. It's a film lens, if you are shooting film why would you want to auto focus. The mic will pick up the noise. Manual F-stop lenses (most of them anyway) do not carry chips inside them that communicate with the camera. The point of the manual is because that's how film lenses work.

I am not sure. Auto focus works good,but manual focus grinds like sand in focus area. Still my favorite lens. Normally use auto focus unless can't get the shot I want

The lense has auto as well as manual Focus. It has only manual zoom with very limited range as the specification says.

No Auto Focus just manual everything. Will with your camera just nothing Auto.

No. They do not autofocus. But once focused they are very stable, even in rough conditions and changing temperatures.

Yes, this lens does have the option for auto focusing. But I clearly find that manual focusing is the better of the two choices. Unlike some lens, this option to change from manual to auto focusing is done by sliding the forward most ring, the one closest to the len's end back and forth. No switch. There is no automatic zoom option. You have to rotate the ring closest to the camera body to zoom in and out. I guess that is why I prefer the manual focusing. But either way, I am very happy with the photos I have taken with this lens. Hope this helps

No, it has no autofocus . It is manually focused. But it does do exposure thru the lens with your F-1

No autofocus functionality - it is a purely mechanical adaptation of Canon EF lenses on Samsung NX bodies. The "peak function" on my NX100 supports focussing greatly, though. Since there is no full-functionality adapter available (and this will probably not change, ever), and since the price is right, I still strongly recommend the item from Fotodiox. It is well crafted and fits perfectly, both on the camera and the lens ends.

I am not sure but I would be surprised if it didn't. It will not autofocus. I never use any "auto settings" so I don't know what works and what doesn't in terms of electronic features. They me closer focus and that's all I wanted. Based on my usage they are great.

Yes, it does. On the side of the camera where the lens connects to the camera, there is an AF to MF lever that allows you to auto focus or manually focus your camera. I am a newbie to this setup (the REBEL 3 with EF-S 55-250mm f/4.0-5.6 IS lens), so that is the extent of my experience with this camera. I have taken a few pictures and they are quite nice. I refer you to your instruction manual for further details...

Hello Brian. I've had this lens for four years now, and while my copy has been beset with build quality issues, I can't complain about autofocus. It's not as fast as some of the newest SSM lenses, but it tends to be quick and accurate.

If you mean "does this have autofocus," then no, or at least not on the Canon-compatible lens. You have to manually focus this lens. However, if you simply don't want to deal with focus, or don't want any Bokeh (you want everything in the frame sharp and in focus), you can set the lens focus to infinity, and you're good to go.

Yes, obviously. I really do not know if there are any new lens without autofocus. Anyway autofocus for this particular sigma is not the best you can get.. All good about this lens but the sluggish autofocus which is even worse to impossible near macro

Sure does - but please read my review, I advise against buying this lens for other reasons.

This lens doesn't have internal focus motor, nor your camera body, so you wont get autofocus with this lens version. You need the version DX II http://www.amazon.com/dp/B007ORX8ME/ref=cm_sw_su_dp

Yes. NOTE: unlike most lenses I've used/seen it has no auto/manual focus switch on the lens-so if you want to use it in manual you have to use the switch on the body.
