Is there a way to adjust the focus. Mine was in focus, but is now out of focus. Lens is clean and clear but the focal distance stuck at about 10ft

Don't worrie. It will eventually fail before it gets to focus. POS for sure. And given the 4 prong connection, not interchangeable with others

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 think I solved the problem by moving the camera lens away from being over the sensor. I found that I had this issue when the lens was over the sensor but not if I adjusted it. Not sure if this helps anyone else.

I wonder if you are using the camera correctly. If you set the camera to continuously focus, and then try to do focus-and-recompose, you will get out-of-focus photos most of the time. The Tamron all-in-one lens, like any all-in-one lens, is not the best lens in the world. But it isn't horribly bad, either. And it normally will not do a lot of focus hunting in decent light. If you are new to SLRs, you might begin by making sure that you aren't the problem. FWIW

Try adjusting the diopter adjustment on the viewfinder- likely was off. Should view and record in focus.

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?

Hi j michael, I suggest checking on the distnace of your camera to your subject to avoid blur and out of focus shots. Thanks_Mitch

First extend it to full length, then adjust the focus. And you can only use it for distant objects. I don't have it now but I remember it do require some trial and error.

Yes there should be a small screw next to the lens..tightening and loosening should focus it for you

I had a similar problem, but in my case, the lens would not open and extend. I looked at various websites about how to fix this type of problem (but on other cameras), but never got it to work. Unfortunately, it was just weeks after the warranty period, and because I really like the camera, I ended up buying another one, which -- so far -- has not misbehaved.

yeah, i had one with a bad focus ring. returned it, got a new one and now it works awesome!

There is a lock somewhere outside the lens near the body. This might prevent you from changing the focal length.

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.

Suggest you, as quickly as possible, return the lens. I waited too long and was unable to do the return. The lens adds little, if anything, to your photos. It's a big hunk of glass that does next to nothing.

Sorry, I haven't had this problem. I think I remember it's best to focus from a normal angle to assure good focus zooming in. I presume you are also careful to center the image on the subject you want sharp. Ther might also be a setting to tell the camera how to handle close up shots. There may be levels orb types if selectivity possible. Depth of field is more critical in telephoto so it doesn't take much to throw it off. Sorry I don't have the camera or manual handy.

I have the same equipment. The situation you describe is not normal in any lens mounted in any camera. But this combination lens/camera use to do it. Put the lens and the camera on manual focus, because the autofocus in this lens on this camera is a nightmare. But in manual mode, this lens is pristine, wonderful.

I have these lens and I cannot use the autofocus, only manual. It won't focus no matter at what range. So disappointed..
