Does the filter adapter allow the lens to function without vignetting at all focal lengths and retract all the way when turned off?

Yes. That is the beauty of this adapter versus the longer tube adapters. Thank you

I've never personally used the filter on a sigma lens, but I'd assume it works the same as on a Canon lens. You will notice that the filter has two moving parts and that the front ring spins continually. The the back ring that is attached to the glass should tighten onto your lens and become secure, while the front ring will continue to spin even after the rear ring has been tightened.

The adapter and UV filter will probably cause vignetting at the wide angle setting of G10. Not fatal but to be considered.

Yes. it's a 77mm filter, and the lens has a 77mm thread. No adapter required.

Haven't specifically tested that lens, but the filter is built for 82mm thread. If it doesn't cause vignetting on my 16-35mm, there's no reason it should on anything. CJ is right, the glass is quite a bit larger than the ring.

Unlike most lenses or adapters that use a button, the silver button on this adapter is not pushed down, it is pulled back towards the camera to release the lens. Took me a minute to figure that one out.

I haven't removed the adapter. I've kept it in place underwater without the lense without any problem at all.

Yes, definitely the thing to do . I'm using mine on a 49mm lens. It stops the filter vignetting by having it bigger than the lens.

The filter holder goes on the end of the lens. Get the correct size lens adapter and enjoy.

This lens adaptor has a graduating filter system. The adjustments are at the backof adaptor.

ADAPTER SEEMS STUCK? OK, this is easy (unless you've already forced it and broken it off.) As already noted in the comments, The silver button on the adapter SLIDES towards the camera and that releases the lens. It doesn't push in as you might think.

It does affect the focal length, but not much. I personally didn't like it. The lens release button is very cheap and broke on me after a full weekend of shooting. The adapter it's self pretty sturdy for the most part. Good thing it's not costly.

Yes, but the UV filter screws between the adapter & the Lense. Hope this helps. Cheers

Yes, the lens retracts when you turn the camera off. With the lens retracted, the camera is so small you can slip it in a pocket or small section of a purse.

This is a bayonet mount not a screw on so it slips over the lens and whatever filter you have on there. Give it 1/4 turn and off you go.

There's a tab that locks down onto the lens preventing you from "unscrewing" the lens out counter-clockwise. If you look at it you should be able to see what I'm talking about. You can use your thumbnail to push that tab up and rotate the lens counter-clockwise to release it from the adapter. Hope that helps.

Yes, there is a plastic adapter ring that snaps over the lens. It has the threads to hold filters and is also how you can attach a lens cap. I keep it and a clear filter on all the time. It uses 46 mm filters. It is not strong, and can pop off. The adapter also holds the camera the right distance from whatever you set it on to use the microscope feature with the built in lights.
