does it work in auto? &amp; does it screw on the front of another lense?

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.

It will work and is a great improvement. However, the lense cap will not screw on completely. Does not effect function just appearance.

Yes it does work in auto setting, I also didn't find any distortion in my photos

Yes, I have not had any issues with this lens, in fact, I love it. I use the auto setting on the camera and all pics have been great!

It works with this one I got here: http://www.amazon.com/gp/aw/d/B00C9L6K3YBasically, it will even fit the larger 4.7 mm deeper auto lens.

Yes it will allow you to connect the Nikon lens to a Canon Body (I use a Canon 70D). I have not found a way to get the Auto Functions to work. So plan on a manual lens and you won't be disappointed. There are other reviews that discuss camera settings to use with a manual lens. It is not simple, and I am not familiar with the specifics of your camera.

Yes. It attaches onto an existing lens using the front threads of the lens. So it never attaches directly to the camera body.

"It will only work in manual at your Lens' highest Fstop ..."Actually the iris (f stop) has a spring-loaded metal tab on the back of the lens than can be slid sideways to fully open the lens. Then a small object, like a piece of a toothpick or a piece of a plastic coffee stirrer can be placed there to hold the lens wide open.

Auto focus does not work with this lense even though I was led to believe that it would.

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 !

If the body has an autofocus screw built in then yes. It will only work as a manual lens on your body, I believe.also, it's a poor performer.

Yes, they are both e-mount. Auto focus and everything will work, but the image will not fill your full frame. EXAMPLE ; http://www.imaging-resource.com/ee_uploads/news/2728/mobile01-917f5a69e007e6834faa541162c976e7__largest-no-more-than-580x630.jpg

I have a 40D. Works in auto and manual. Well worth it for the price. I use it forWedding photography and it works flawless. Hope this helps .

You attach it to the lens (or hold it in place if you have an older version), and take a photo. Your camera has to be on the "PRE" setting for it to work. Works better than automatic.. And more constant, since automatic wb reads from the focal point, changing if you focus on other items, or when you move camera.Very easy to use. Much recommended! :)There are a few videos on their website and YouTube.

In auto mod it changes. But in the manual mode you select your f and focus manually.

Yes it does, just remember that this is a manual lens, no electronic connection, no auto focus!!
