this lens doesn't focus on it's own?

85mm is amazing lens, crisp images. Great for portrait shoots. The problem is it is a manual focus lens. It takes time to get good using it but its worth the price.

It's a manual focus lens which means you do the focusing. You can pay extra for an upgraded version of this with auto focus chip Which I did but I have only tried that twice so I cannot say I did everything right and haven't cared to really sit and play with it because I am a manual shooter. The quality of the photos you get with manual focus are amazing though!!

Hi Chris,Is this lens new or used? Because as of today it's malfunctioning while zooming in-out

Your sensor might be dirty - this requires professional cleaning. The battery would have nothing to do with it. Your lens might be set to MF (manual focus) on accident too!

Is the cannon macro/telephoto? That could be a factor. Im not sure. I dont have this lens yet. Though it will be my next lens once I get this return issue with the Sigma resolved.

Hey Aaron, common mistake. What you need to do is set the actual aperture on the lens ring to 22 and the lock it on that value so that the little red line aligns with the 22. This happens because you are using an older non focusing lens on a newer body. Problem solved. Have fun, that is a fantastic lens.

I don't have my camera in front of me, but I don't recall any setting to change the focus.It would most likely be one of the preset shooting modes the camera has that would produce a shot like that.

This is not normal. You may have a problem. Where is the focus ring? if its unlocked then the lens won't auto focus. Check that out first.

Sorry, no. There is no mechanism for auto focus on this lens (difficult for this type of usage anyhow).

This lens will not auto focus on select, C-sensor bodies. However, it will on the D70.

you likely have to use the manual focus ring on the lens itself. This adaptor doesn't allow for auto-focus capability.

None at all on my M- it is a bit slow in the focus- but when I combined it with a short loupe to act as a viewfinder it became handy. Mine works perfectly except for the focussing time. VRR

Let me guess, your images are not sharp. This lens will fit on your camera, and images should be sharp from F2.8 and up. If they are not. You have focusing problems with your camera body.

There should be a switch on the cord with an on/off button. Or try turning the lens.

This lens does not have an autofocus motor so regardless of the camera you have it will not autofocus

I can't say that I have. The lens I use this adapter on does not have an Auto-Focus. Having said that the AF on my other lens has been acting a little strange lately.

i am not sure i understand you, but the biggest lens are notfixed, you put in the case, and it's possible to set the focus, like a zoom at an old regular camera
