A case for xD bodies - micro adjust

So I just got my 5D Mark II today, and beyond the awesome creamyness and detail of the full frame sensor, I didn't realize how much I was missing out with my 60D and it's lack of a micro focus adjustment feature.

Some lenses were just always a bit softer than I thought they should have been on my 60D, but especially my 50 1.8, and 135mm F2.

Come to find out that my 135 was backfocusing about 10 units and my 50 1.8 was front focusing 17 points!

Now the 135 is sharp as heck wide open and the 50 1.8 is finally acceptable at 1.8.

To me, this feature alone is worth investing in, and it's something for Rebel users to think seriously about when looking to upgrade bodies. If you don't want full frame, think about a 50D or 7D.

I dont remember the name atm AMD I'm not on my computer. I'll post it when I get home.

Note, I printed it on photo paper and mounted it to a block of wood for rigidity.

I've used a DSLR for years without "micro adjust" and the pics looked good, even on focus charts
Maybe I've just been lucky or perhaps it's a psychological thing

You've been lucky... can you not see the miscalibration in the attached photos? Do you have any lens with a 65+MM diaphragm? If you are only using zooms and not fast standard to telephoto primes, you are unlikely to have a DOF shallow enough to notice missed calibration.

I'm glad that you haven't run into any issues. Others aren't so lucky, and it isn't as if canon engineers the technology into their cameras for no good reason.

Thanks for the download link, will have to get to this as I have noticed my 135 is a little off and need to adjust!

I like this design as it allows the focus target to be perpendicular to the lens axis ensuring that you won't miss due to focus-area error, just make sure you aim your focus point in the middle of the target area.

how do you know that the angle of the flip out area is exactly 45 degrees and that your camera is exactly perpendicular to it? if its even slightly out you may get a false reading

your lenses are out that much on your 5d2 but you have fixed them with micro adjust.

There is no real way to tell how much they are out on the 60d in microadjust clicks. You can tell how many mm they are off though.

it could be that your lenses were on or very close for the 60d and off by more on the 5d2. every body is different.

it's the target that needs to be perpendicular to the sensor for sensible test results, the angled rular is just guide to show how much front/rear the focus adjustment actually is...

I thought only Sigma lens had focus issues.


....the best camera is the one you have on you at the time.

I did test all the leses on the 60D prior to the 5D2 arriving. The 135 and 50 were out of spec on both bodies.
