Yes it is. It tends to spend a long time seeking in low light, but the auto focus is pretty good.

Yes it is. The new version has OS and I would recommend it. The lens is heavy and slow, but for nature and outdoor versatility it rocks. I am not a professional but the images quality is very good.

Yes. This will auto focus even on cameras that don't have an internal AF motor built in.

No you have to be in manual mode on this one, but it works great when you do...I just switch back to Auto when I am done (I usually stay on automatic 95% of the time and only use manual every once in a while)

Yes, it is automatic but single action. This means that it only shoots out and doesn't close automatically. If it was double action then it would automatically open and close, both ways.

Very slight as it is auto focus, I am just figuring it out but so far, I love it

There is an auto off feature. You probably accidentally activated this feature.

No,but your auto focus ring isn't engaged . The big rubber ring at the very front of the lens must be pushed forward to engage it and pulled back for manual focusing ! I don't have my lens or camera handy but I'm pretty sure forward is engaged and back toward you is dis engaged ! It's a snappy little lens once engaged !

dont know technical of it. but I would say no. off/auto means its off until automatically activated in the water.

Yes it's fully automatic. It just doesn't "report" its presence to the body (so the camera will indeed try to AF).

Yes it has the same mounting but the only thing you cannot do is use auto mode everything has to be done manually, enjoy

Hi. Yes it is. This lens is a simple drip-proof. In addition, the auto focus is smooth lens within the motor. By all means, please buy in our shop. Thank You. COOL JAPAN OSAKA

No not automatically. The weight is what it looks for to determine the appropriate profile. You have to select the profile manually otherwise. Mine doesn't work properly after barely using it by the way.

Usually yes. If you're in an auto mode there me be a delay for focus / light metering etc like most dslrs. However none of that in manual.

It screws on to the front of your lens. There are adapters for different lens diameter sizes. Yes it does work in auto - both auto focus and auto shooting mode.

I am unsure since I gave it as a gift. I will check and get back to you. Mine is all automatic though.

Manually it works great, but the auto?.....not so well. Took some outdoor pics of my nephew's. It was a sunny day, no clouds. Went to take a pic under a tree but it was so bright behind him, he was a black silhouette. Tried zooming in and out to try to get it to recognize where I wanted it to focus; it it didn't work. Tried turning the flash on while in the auto setting. It wouldn't work either. Have to go into program settings to get the force flash to work. Have to adjust the aperture to get the backlight (not every time, but whenever it won't do it automatically.)
