Is this lens auto-focus?

Yes...quite quickly too. Although it is not the sharpest glass for the NEX system, it's priced right and covers a great zoom range.

yes, it has an auto-focus, but at times, it cam be sort of slow, but overall, it is a very good lens.

It is but it won't have auto focus. And u will have to set Aperture manually. But otherwise it's a great lense with fantastic shallow depth of field!

Yes, it does auto-focus. I now use it on a micro four-thirds camera which requires that I use an adaptor. This slows the auto-focus.

This is a purely manual lens. It does not auto focus on any camera body. If you buy the chipped version of the lens, you can set aperture from camera and you can see the green dot in view finder that helps in manual focusing.

YES, with full autofocus capabilities. When I first bought this lens I used it on my D70. I love this lens! Just got back from hawaii with it and it was a joy to use as always.

I can only comment on it being autu focus. It focus nicely, automatically, very sharp pictures.

Yes, it is a manual lens but its not hard to use at all. You have to manually set the focus (easy enough) but you can still use the cameras internal meter to control exposure. Also, read your cameras owners manual. There are some neat tools available to make using this lens a little easier.

I can't say that I have. The lens I use this adapter on does not have an Auto-Focus. Having said that the AF on my other lens has been acting a little strange lately.

Yes but autofocus will not work well above F5.6 although manual focus works well. I have this lens. Manual focus sort of defeats the purpose of this quick focusing lens.

No, not in auto-mode. But you can fine tune the focus when you switch to manual focus on the lens, and you leave the camera set for auto focus.This is different than other Pentax lenses that don't have the switch on the lens, this may be due to the fact that this lens was built by Tamron. I don't find this to be a big deal though, and enjoy the lens a lot!

It's an autofocus lens. There is an outer ring that pushed in one direction will be manual focus only. Either pull the ring closer or push farther away and you should get autofocus.

It will not autofocus. If you purchase this lens you will have to manually focus all of your shots

No. This lens is manual focus and made for long distance shots. It is also pretty heavy. I would try a Tamron 50-200mm

It is manual focus. You can beat the price. The quality is good and it is a super-big zoom lens.

Yes, this lens is both auto focus and has a selectable automatic diaphragm. It can be used either as a manual selectable diaphragm as well as an automatic diaphragm when set on the "A" setting on the diaphragm ring. The auto focus is accomplished with a screw drive powered by the camera. It does not have an internal drive motor for the auto focus.

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

This is a very basic lens. There is no autofocus, stabilization, or even adjustable aperture. It is also a slow lens. You need a good stable tripod, and no fast moving subjects.
