Just wondering, what percentage of people's microadjustment settings were affected by the new firmware 1.2.3
I've heard many stories that some people no longer need microadjustment on some lenses, while others say no difference at all.

I originally micro-adjusted my 1d-III. A couple lenses were off in the +/- 15 range, so I sent them to Canon. Half the rest were off just a bit +/- 5. After the sub-mirror fix(mostly an adjustment to spec on my 1d), I was able to turn off the mircro feature. I've only shot with a few lenses since 1.2.3, but they've all worked perfectly. Micro-adjust disabled.

So, NO, no adjustment needed after 1.2.3.

Well...I'm not sure where my settings fall.
I just received my Mark III yesterday, took some quick snaps at work but the second I got home I upgraded the firmware. I adjusted my 70-200, 24-70 and 50 1.4. My 100 f2 that is calibrated was spot on, my 120-300 is loaned out.
Not sure what to make of that since I do read that some people no longer need the microadjustments they had made previously.

I used the Live View focus check with 1.1.3 and found 0 for my lenses was optimal so I left MA disabled.

Installed 1.2.3 and nothing has changed.

Strangely, yes. My 100-400 went from +17 to +12, but then it could just be my bad eyesight and my feeble brain believing it had to change because others peoples did.

not affected for me.

for those who answered yes. as i believe that the microadjustment process may vary from try to try, i would suggest this experiment. repeat the microadjustment process again, and see if you get the same results. i have found that i sometimes will come up with a slightly different set of numbers for all my lenses, without any thing else changing.

You know, I think it depends on testing method. I NEVER could get accurate results with any test charts or moire patterns etc.
The only thing that worked properly for me was to go out and shoot real subjects, using trial and error.

I'm just laughing at that one because you're SO right! You can agonise over mtf results and focus charts all you like. You can't actually beat getting out there and using it for taking photos :lol: it soon shows the cr*p

I'm not saying they don't help, but sometimes we forget what it's all about.

cheers

Heh, perhaps I dont have a good enough tripod to use charts. But I got different results EVERY time, with the majority showing 0 adjustment was best. But outside in the real world it was a completely different story.

For example, one day I went out and shot this tree (external link), first at 0, then at +20, and whittled down to +10 being the best. Then I tried many other subjects, and each and every time +10 gave the best result. And I did this hand held, no tripod, because that's how I normally shoot. My formerly "soft" 70-200 is now "razor sharp", almost as good as my ol' 135L :)

No micro adjustment needed before or after the upgrade.

So far it looks like the majority aren't seeing any diff in calibration after the firmware update.

Initially I thought I had to change my MA but after a shoot this past Sunday, my MA had to be the same, so firmware did nothing for my MA settings.

I most definitely noticed a difference. especially in my 16-35L. I need to re-calibrate them all to make sure they are still working properly, but my 16-35 is definitely out of wack.

I can't figure out Live View focus check method for microadjustment after reading the original article. Can anybody here brief it in an earlier way for me? :o
