I've used Micro adjust on my camera to get my lenses right for me. Now I've never done it properly with a chart but used objects. Today I had some free time to print out a focus chart and get them all set 100%.
Here are my results:
Sigma 24-70 HSM +20 @ 70mm | +8 at @ 24mm (grr)
Sigma 50mm f1.4 IS + 16
Canon 135L - No adjustment needed
Canon 70-200 f2.8 IS Mark II - No Adjustment needed at 200mm | Maybe needs -1 or -2 at 70mm.
Tamron 90mm Di II Macro - + 12
The Sigma 24-70mm really bugged me as as the micro adjust needed varies across the zoom range. It's a shame you can't set cameras to have multiple adjustments per lens.
I know Sigma's are bad but are your Canon lenses like mine near perfect?
