Hi, This item can be mounted on a camera Sony A99? Work properly autofocus, automatic exposure and flash? May I know the size and weight? Thanks

This lens was made by Sigma for Canon cameras only. I do not think it will be compatible with Sony products.

I have used it with a Sony Alpha A5000 mostly to photograph the moon. The results are very good. But it is heavy and needs a sturdy tripod for best results.

It should, since it is an A-mount SONY lens. (Congratulations on choosing a very nice standard lens, by the way!) This lens, I believe, was designed for the earlier, APS-C cameras SONY created such as the A55, A65, A77 and their older siblings. With this lens's relationship to their smaller sensor, you may see "fall-off" of image acuity around the edges of the bigger sensor found in your A99. That shouldn't be a problem and I would bet that, even if that did happen, it wouldn't take much to either eliminate the effect or adjust for it.

Yes it will mount but you lose two stops on a 2x T/C. Autofocus will typically work above 6.5. Therefore autofocus is problematical. Manual focus will work fine.

I use this flash on the A77, which uses the proprietary Sony flash shoe. I believe that the A99 has a standard flash shoe, which would not fit this flash.

I am not really sure! I had set my settings on automatic and the flash only worked when it was needed. I am sure there must be a way to keep it on, but I really don't have the answer for you. You may be able to download the manuel for it from the sony website. Worth a try.

This mount will not be a good mount for a DSLR size camera. It works fine for a small point/shoot compact camera, but it is not sturdy enough to hold a 2 to 4 pound camera steady. I bought it to mount to a rifle scope and after some slight modifications it works ok for that, but my camera is a small Casio high speed camera. There are no adapters that come with it. WYSIWIG. There is a 1/4-20 mounting screw on the perpendicular bar that attaches to the bottom of the camera.

The battery grips for Sony are unique per camera model. So no, it would not work on the A99

May work on a Sony you will have to check the site to see if they have a mount for your camera. No as to auto focus which I keep turned off anyway. It has it place if you don't have time to compose.

I have the A77, so I can't speak about the A99 with certainty. The Sony version of the Metz 58 flash works perfectly with my A77 - no need for the adapter.

This will work on an APSC camera like the A58. It will act like a 35-110 which is mild wide angle to short telephoto lens. Be warned the lens is much heavier than the other Sony lenses. If you plan to use it as a walk about lens the weight will be noticed. Get a good neoprene camera strap as the strap provided by Sony is not going to cut it with the A58/CZ setup.

It attached to my Sony A65 and will attach to your A57 if you get the Sony/Minolta T-mount adapter with it. Getting the desired result from its use is another matter. It did not work well for my intended purpose, but I have to take much of the blame for that. I did not have a solid enough tripod for a lens of its length and weight and I could not focus it clearly. As a result, I missed the wildlife shot that I wanted to get. This probably could have been avoided if I had practiced with it before the moment arose.

Yes it works fine with the A99, both on-camera and off camera, including with Multi-flash set-ups. But yes you need the adaptor.

This lens is available with a Sony mount. It can only be used on a APS-C sensor camera (the A-77 has an APS-c sensor)

It didn't work for me. I bought it for use with my a65. It attaches to the camera fine. But it tried to use an old Vivitar flash unit with it and it didn't work, i. e. the flash wouldn't fire. The manual claims it only works with Sony equipment, all I know for sure is that it didn't work with my non-Sony equipment.

Hm, not wanting to be rude but if your going to spend 1700$ on a camera body it seems like you might want to invest in a nicer flash. That said here is a quote from Sony about the flash on the Sony A7II. "Sony &#945; System Flash compatible with Multi Interface Shoe. Attach the shoe adapter for flash compatible with Auto-lock Accessory Shoe." If that does not satisfy you; here is the link to Sony corp about the A7II http://www.sony.net/Products/di/en-gb/products/v6cd/specifications.html?contentsTop=1. The reason I'm being so succinct is I'm tired of being criticized by others on this site.

I have one that is China made called "Shoot"...looks exactly the same as this one visually, but it has to have the 3 female mini-pin wire connection to work with the a77 (which mine has). That would appear to be the only thing to watch out for. Otherwise, like other people have mentioned is the fact that there is no On/Off button, so once you put the AAA is there, it is on until they go dead ! It works as promised and is really simple to set, and since the A77 can take great pictures in Aperture Mode you can get some great interval work done.
