Hi all
Could do with some input please. I received my new 70D earlier this week. Haven't really had much time to try it out in good light until today but didn't think it was that sharp with my 17-55mm. This morning I compared some similar shots with the 17-55 on both my 700D and 70D and the 70D did look softer.
I decided to download a copy of FoCal, (I'd planned on doing this anyway at some point). This have given me the following results for MFA adjustment on various lenses.
Canon 10-22mm f3.5-4.5 = W: +7, T: +8
Canon 17-55m f2.8 = W: +12, T: +11
Tamron 70-300mm f4-5.6 VC = W: +7, T: +6
Canon 50mm f1.4 = +16 (FoCal seemed to struggle with this one so ended up tweaking it manually with a rule.)
So it looks like there is some variance in the lenses but they all needed at least +6 MFA suggesting either they're all front focussing or the body might be off 0. I'm trying to figure out if this is acceptable/normal. If the body was spot on I'd have expected them to have been spread either side of zero or at least some closer to 0.
However I have been able to fine tune all of them with reasonable success and the 17-55mm is now as sharp on the 70D as it is on the 700D. So I seem to have a functioning setup at least.
Has anyone experienced this?
