I don't have a camera with micro-adjust, but I have a pathological need to answer polls where I have no personal experience. Please check here if this is you.

This is probably the right time to ask. How do you describe what back focusing or front focusing is?

It's when you press the focus button and the camera blasts out that incredibly loud beep (;)) telling you that it's in focus but when you look at the image on the computer the actual focus plane is in front or behind the subject.

I've tuned up all but two lenses and the MPE-65 is one of them. :) It totally saved my 100-400. I was so pi$$ed off with that lens. Worked 1/2 decent on a XTi, total trash on a 40D and i avoided using to as much as possible. Once tuned on the 50D it became a totally different lens. Sharp and hits focus nearly every shot. Si That one feature turned a $1200 boat anchor into one of my favorite lenses.


Not sure why, but call me JJ.

I've noticed sharper shots since I dialed in the focus of two lenses with a microadjustment. I use a commercial product to do it, as I could never get the cut-out paper things to work reproducibly.

Maybe a retarded question, but hey... lol

Is it always a problem with the lenses - and NOT with the camera - when it comes to back or front focusing issues??
And does it means that the lens is faulty in any way if there are issues with FF/BF or it could mean that the lens is fine but just not working well with the certain camera??

Thanks.

It can be both lens and body. One of the shortcomings of a SLR camera is that the image that will be exposed on the image sensor is not the same image that is used to focus, neither manually nor automatically. If there is any diffeance in the leangth of the light path, from lens to AF sensor and lens and image sensor, the camera will think all is in focus when it is not.

I remember my first roll of film that was processed. Man was that a major let down. :(

AF Micro adjustment was one of the featurs that swayed me towards the 50D instead of the 40D when I upgraded.. I'm glad I did..

My favourite lens, Sigma EX 50-150mm f/2.8 APO is sharp as a tack on my 20D but front focused before I did a some AF Micro adjustment on my 50D.. All is good now. My Canon EF 50mm /1.4 USM also front focused on my 50D.. My three Tamrons are sharp straight out of the box..

It's not a problem with the 50D or the lens alone but the combination of the two..

AF Micro adjustment,,worth its weight in rocking horse s**t!!

Think you missed an option in the voting, it does not seem to make the slightest difference, as I have had several cameras with it, and after extensive testing I cannot tell the difference it makes

As long as you ask, LensAlign Pro (external link). It's relatively expensive compared to a paper target. But not compared to a $1000 lens or to soft edges in your shots. And in my hands, it eliminates the soft edges completely and works reproducibly.

I've tried paper targets, followed the directions, got a result back or forward, shot with it, had some improvement but not completely sharp. Tried it again, got a different result, same thing again. With the Lens Align, I got sharp shots. When I bumped by camera one time, I re-checked it, and got the same measurement as the first time, and sharp pics thereafter.

It's worth the money to me. YMMV.

I played with the adjustments on my 70-200 f/2.8 at a basketball tournament this past weekend. Looking at the images on the LCD at full zoom, I couldn't tell any differences. I tried +5, -5 +10, -10. Finally I went back to zero and forgot all about it.

Unfortunately, I forgot which game (out of 17) I did the test on so now I won't be able to check the images on the PC.

MA has made my 70-300 f/4-5.6 IS USM a much sharper and useful lens.
