does it have automatic focus
888895
I have not been happy with the auto focus. I have used this lens with both a cannon T3 and a cannon 70D. The problem is it will no come into focus. I have contacted sigma asking if there is anything that can be done about this. I have not yet gotten a reply.

Yes, it has auto focus and optical stabilization (same as Nikon VR). Both work very well on my D7100 and D5100.

As stated by the other respondents, yes it has autofocus which can be switched off to manually focus. I've had no issues with the autofocus on my Canon 40d. I also own a sigma 1.4 teleconverter. With the teleconverter on the autofocus doesn't work and you have to focus manually. I've found that 500 is usually plenty of range so honestly I've only had the teleconverter on it once and then only to play around. I was also highly impressed with the OS (Optical Stabilization) on this lens. It is very heavy, but with the OS it is actually not nearly as hard to hand hold as I thought it would be. (But I always use a tripod if I can... no kidding it's very heavy!) Hope this helps! -ed As stated by the other respondents, yes it has autofocus which can be switched off to manually focus.

Yes , both auto focus and manual, but, I've not been happy with the manual focus.The auto focus works great on my Nikon D90.

It requires an electronic connection to the camera to focus, yes. The manual focus is focus by wire, and not a physical focusing mechanism unfortunately.

It automatic mode the camera focuses fine. I haven't tried it in other modes yet, but if you have an autofocus lens I imagine it will focus for you fine.

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

It won't auto focus or auto expose on anything, as it is totally manual. It's worth every penny, though.

not sure what the question is . Yes it has a auto and manual focus switch. If on auto on my A77 I can't override the focus for final adjustment of focus while still on auto focus. The camera will bring the focus back to what it wants unless I press the override button on the camera, or switch the lens to manual. Hope this helps

Sorry, no. There is no mechanism for auto focus on this lens (difficult for this type of usage anyhow).

No there is no auto focus with this Adaptor. It is all manual. I'm using this on my Panasonic Gh2 camera. The manual focus ring is smooth and easy to use. It's worth the buy. Trust me.

Yes it does. I am using a Mc lense on it. Keep in mind it doesn't have and automatic functions. I use the vintage lenses manually.

It will not auto focus but it will work. A piece of advice : don't buy it. It is very very bad lens.

This does not have automatic focus. It does pretty good for the price. Its small and compact and fits in my purse and that's why I purchased it.

Yes this lens has auto-focus. I have used it on one outing to the Miracle Garden in Dubai and it was awesome. I have been trying to get a good solution to macro photography. I have tried extension tubes, close-up filters and decided to spend the money and try a macro lens. I am glad that I did. This lens in my opinion was well worth the money.

No it does not. You have to manually focus and its really hard to focus on stuff long distance

Yes it does, that's the camera I have. It does have the motorized focus also. Excellent lens!

Yes you can manually focus this lens. There are focus and zoom rings on the lens. You just need to set the camera to manual focus mode to do it.

I believe it does have manual focus (haven't dug in to deep yet), and the auto focus is just a tad bit slower than expected (barely noticeable). It does have a date stamp option with multiple choices. If you want to try a hands on, most Best Buys currently carry it, but it's usually full price (possible price match).

I have the Nikon D5100 and yes it does auto focus the camera before taking the picture
