I finally received my RRS L-Bracket in the mail yesterday. With that said, I thought it was time to see what this camera can do (1Ds MkIII). Of course, I had to make sure my lenses were tack sharp. In order to do that, I had to find out what the "AF Microadjustments" was all about.
One word...WOW!!! I thought my lenses were sharp and sweet before. Shoot, based on my results, I should have thrown the lenses away. Of course, I would never throw them away. That's like asking a crack head to give up his supplier. In short, these lenses are far sharper now than ever before (except for the 85mm).
In the end, I made the following adjustments...Tell me what, if any, were your adjustments? I'm curious to see what others are experiencing.
Canon 14mm f/2.8 MkII (at f/8)
+20
Canon 50mm f/1.4 (at f/8)
-10
Canon 85mm f/1.8 (at f/8)
0 (no adjustment needed)
Canon 135mm f/2 (at f/8)
-20
Canon 135mm f/2 (w/ 1.4x MkII) (at f/8)
-10
Canon 24-70mm f/2.8 (at f/8)
+5
Canon 70-200mm f/2.8 (at f/8)
-20
Canon 70-200mm f/2.8 (w/ 1.4x MkII) (at f/8)
-20
Tamron 28-75mm f/2.8 (at f/8)
-20
By the way...Is the Canon 1Ds Mk III the first and only camera to have this feature? Do any of the other Canon models allow you to perform this mod...what about Nikon?
Thanks,
Karl
Karl,
All of the +20 and -20 adjustments seem to indicate a problem with your micro adjustment approach or equipment. Other posters have brought up other problems (MA only works at some distances, what distance to use when MA'ing, etc.) ... these can also be caused by a bad approach to MA.
Here is a link to a procedure that can be used to get accurate results: http://www.precisioncaps.com/training_af_micro_adjust.html
Good luck,
Bill.
