When it says "complete manual focus" does this mean it won't work with autofocus as well?

This is a very good auto focus lens. However you can turn auto focus off with a switch. When in auto focus mode, you can also refocus the lens to another subject by simply rotating the focus ring without the need to turn off auto focus with the switch.

The Canon EF 35mm f/1.4L USM works very, very well with autofocus. The USM is for "UltraSonic Motor," Canon's way of advertising their very fast, very quiet autofocusing system. One major advantage of USM is that you can still focus manually on top of the autofocus, in case the camera was looking somewhere different from where you were looking at. That being said, "Complete manual focus" just means that you can turn autofocus completely off, and switch to manual focus only. Even when you do that, the lens will still communcate with the camera, and you lose none of the features of the lens/camera system other than being able to completely control the focus manually.

Incorrect. This lens auto focuses!You can manually fine tune the focusing quickly with the manual focus ring if needed. "Many EF lenses are equipped with a ring-type USM which allows full-time manual focus in AF mode. This means you can manually fine-tune focusing as soon as auto focus is complete, without having to switch to manual focusing mode."-google

Autofocus does not work with this adaptor. Use manual focus. It's like driving a stick shift car - once you learn, you will have more fun.

It automatic mode the camera focuses fine. I haven't tried it in other modes yet, but if you have an autofocus lens I imagine it will focus for you fine.

Yes, but more importantly it allows control of the f-stop on your lens. You will have a very narrow depth of field in any case, so you will probably find manual focus is still preferred in order to focus on the point you want.

I tried with Canon 13mm F2, the autofocus is not really working, very difficult to find focus but other function is okay

This mount does not allow you to take advantage of full functionality. Your auto lens must used in manual mode. I manual focus my lens in aperture mode and it works just fine. At this price you're not going to get bells and whistles, other than a solid, well made attachment for a fraction of the price of the full-function oem device.

It won't auto focus or auto expose on anything, as it is totally manual. It's worth every penny, though.

AutoFocus was fine. Some circumstances, e.g., bird watching, require manual focus.

No autofocus functionality - it is a purely mechanical adaptation of Canon EF lenses on Samsung NX bodies. The "peak function" on my NX100 supports focussing greatly, though. Since there is no full-functionality adapter available (and this will probably not change, ever), and since the price is right, I still strongly recommend the item from Fotodiox. It is well crafted and fits perfectly, both on the camera and the lens ends.

No what full time manual focus means is you can correct the focus as the focus ring stays connected and you can override auto focus at any time after it has locked focus, however as I have never had any pictures not pin sharp from this lens relying on auto-focus I never have to use the manual focus ring, the lens snaps in to focus first touch of the shutter every time, just wish my other lenses were as good as this one at getting it right when you need it, best 300 on the market IMO, much prefer this to the 2.8 version.

There isn't "manual" focus like you have with an SLR or a DSLR lens. The method described on page 106 of the manual used to be called pre-focusing which also works with AF SLR/DSLR lenses. This method will only work before you start recording in video mode.

No auto focus control, even if you're using lenses with AF. (At least for the canon lens mount, though I expect all the mounts are like this). Also, iris/exposure control is limited on some lenses. Check their website to see what works.

This is why I bought a D800 so I could use all of my old lenses. Use another old lens of the same kind to see if it works but I doubt it just as others have said that it will not work with autofocus. The 35-70 was first sold in 1963 and is still one of the best.

I am not sure I understand what you are asking... the camera should focus, but only manually.

No, autofocus doesn't work. You have to set the camera to manual mode and manually focus. However, it's not that difficult once you activate the zooming mode to help you focus.

It won't autofocus on that particular model because your camera has no internal autofocus motor. You can still shoot with it, but you must manually focus. The good news is that you have in-finder focus confirmation dots that will let you know if you're in focus, and when you eventually upgrade your camera body, you'll have a nice piece of glass to use with it.

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.
