The photo of the lens on Amazon shows an AF and MF switch. My version does not have one and I need it. Was there a lens change?

I have one of these for a canon mount. Mine does have autofocus. http://www.sigmaphoto.com/product/8mm-f35-ex-dg-circular-fisheye They do not show any new lenses replacing this model. Is yours for a canon? If not then maybe some models for different mounts do not have autofocus.

Hi Russell, I don't know if there was a lens change, but mine has both the AF and MF switch (I bought it 3-4 months ago). As I am Google Trusted Photographer my lens stays in the MF mode all the time. It's great a lens and make fantastic panorama pictures.

Hello Martin, Go to your menu and navigate to the number one page. You'll see "Release w/o Lens", change that to enable and you're set! Hope that helps!

I've shot with the 14-35, 35-100, 50-200, and 50. I'm coming off a rather battle worn E-30. I think it's faster and more dependable by far. Coupled with such a big bright viewfinder and you can see exactly what is happening in AF and MF (with enlargement and peaking). The 14-35 screams. I'm sure the newer MFT lenses are optimized but I can't believe it would need to be much faster. Even the old 50 macro, which was never a speed demon, is behaving quite admirably. But do get the grip. Put that with some big glass and it is a very sweet shooting combo. Smaller and easier to handle than a comparable DSLR rig but still pro.

It just so happens that yesterday I tried the 2.0 on my 7D Mark II with the new 100-400 II lens and it lost its AF function. It works fine with the 1.4 extender, though.

Nope, just make sure you buy the version for Canon and be away that it's a manual lens(no AF)

Often times Fuji AF system frustrates me. I hear that XF35mm lens performance might feel better with X-T1 but with my X-E1 your description is really familiar to me. When it happens, I put it in manual focus mode which makes a great photo.

I would presume that this is normal, as my 14-140 OIS switch is also the same way. Other than that, I think it is a terrific lens.

It has that standard AF/MF switch on the side. Set to MF and you adjust the focus with the ring. It's like the other lenses I've used from Canon and others. I'm not sure what slip-ring would be, unless you mean it focuses and then you change it. I haven't tried that.

I just figured out how to do this today with my new lens. Since Sigma did not put the autofocus/manual focus switch on the lens itself, you need to go into the information menu (the i menu on the lower left side of the camera) and set your focus mode to manual (change the AF-A on the right side to MF). Once you override the autofocus on the camera, use the outer ring on the lens to focus. Hope this helps! Took me a little bit of research to find this. :)

If I understand your question correctly all you need to do is set the switch on the lens to AF.

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

It looks like they used the wrong image when they did the ad. They seem to have 2 or 3 ads for that lens. I do love mine it OS a great walk around lens.

Many thanks for replying. Have just ordered an adapter ( cheaply), as I only wanted the lens to play around with. Lesson learnt ; Hubby cannot buy lenses without me knowing what he's paying out for !!

For some reason, Canon seems to use FULL TIME Continuous AF - which is active even when you're not touching anything - and turned it on by default. Very annoying feature. I didn't realize this either until I popped on a noisy EF lens and it just wouldn't stop auto-focusing. I suspect Canon decided this would somehow make the camera "easier to use".

there is no way that I am aware of to change the lens system. it is all self contained.I have had very good luck with mine as is. I hope this helps answer your question

Did you ever get a lens? I'm making the same decision now. If so, what did you buy? Are you happy with your decision? Is there anything else you would add that would help me make a decision. Thanks!

There is no electronic communication between the lens and camera. So, the AF will not work. There is no such an adapter will allow Nikon Lens work with MFT exit yet.
