What exactly is the so called MICRO FOCUS and how do I adjust it? Directly in the lens???, through a software or through the lens menu? Thanks.

This is a "Stepping Motor Lens". MICRO FOCUS is an automatic feature of this lens.

I have the same problem and mine miss focuses too. I have contacted Nikon, but I'm still waiting for a reply. I'm curious if this lens is a waste of money? Did you guys ever find out what was wrong?

J. ONeill says: Did you make a decision? I am currently debating the same two lenses. I am leaning towards the Canon since it seems there are quite a few quality/AF issues with the Sigma. Any advice is appreciated. If you own a camera with micro focus adjustment like the 50D or 7D, Sigmas front or back focusing is a non-issue. Also, even if you don't own a camera with micro focus adjustment, if you get a Sigma lens that front or back focuses, you can send it to Sigma for calibration.

Wanted to let you all know that I decided on the D7000 and picked one up today. Couldn't be happier. Continuous autofocus during video shooting is useless on it, but I'm learning to manually focus, which is actually more rewarding for me; when shooting at f/1.8 you can get a very cinematic look focusing manually, even when you're chasing around your twin toddlers!

You have to be able to turn the lens incasement in order to adjust focus.You also might need to clean the lens with soft lint free cloth to remove any fingerprints that may be on the lens. If you haven't got too far on the install, you maybe able to adjust then reinstall. I hope this helps.

My difficulty with using this type of lens is the fine focus adjustment. It was not possible to do on my Canon 60D. Is there any way to adjust the lens?

My Daughter has this Camera and now her auto focus isn't working on it, so she has to manually focus it. I'm wondering if it is the lens or is it the body of the camera. She only has one lens so she hasn't been able to trouble shoot the problem and since she's away at college I'm unable to do anything about it at the moment. Anyone have any ideas?Thanks

I have this problem But I don't understand your solution, Bruce. Could you or someone explain it again please? You appear to be saying that if the camera is at something like a standard focal length you can choose both Macro and MF. But you can't - not on mine anyway! In my experience, the camera will not focus below 1ft. The image stays blurred and often the yellow central focus frame will display a question mark. Auto-focus does not work in Macro either - so to all practical purposes the camera has no Macro mode. If someone has a fix for this I'd be very interested.

I just received one of these today. There is no autofocus on the D60 for this lens, so you have to set it on M. Also, if you want the aperature to be set by the camera, you must lock the aperature setting ring. I've only been playing with it for a few minutes, but I've noticed you cannot always open the aperature to f/2.8 using the camera controls; sometimes only f3.3.

This is the most easiest lens I have ever used....because you will almost never have to adjust focus, just keep it around 4-5.6....every thing will be in focus. Its quite sharp.

There was an update released a while back for the focusing problem. It has been resolved. BTW: Get the MKIII's full frame.

Hello... To be honest, I returned the lens because I could not figure it out and I realized I bought the wrong lens... Good luck...

As far as I know, there's no focus adjust. It's auto-focus, and everything in the FOV appears in focus all the time. I've never seen anything be out of focus.

Twist the lens. It may be that it is indeed too low to get a good focus. If you twist the lens on mine, it comes into focus.

Turn the little black thing on the end of the lens a little at a time, that will focus. Then u can mov

Hello, there is an Auto Focus on this lens. Click the switch by AF - M to use Auto Focus (AF) however when shooting Macro, it's usually better and easier to manually focus. I hope this helped.

The P Q10 is like most digital cameras, you change the focus by centering the view finder on an object and lightly tapping the shutter button. This will force the camera to refocus on that object. I don't believe there is a way to manually adjust focus like you adjust zoom. Practice with the light tapping on different objects in your field of view and it will become natural to shift your focus on anything in your field of view.
