| p.3 #6 · Strange front-focusing problem with Sigma 35/1.4 |
Case in point: I'm borrowing a friend's OMD E-M4 + Panasonic 25/1.4. I'm getting a far higher keeper rate and sharper pictures than with my 5D3 + L and L-quality lenses, even with moving subjects. That does not seem right.
Sure it does, it's a badass combo (assuming you meant the E-M5 ). In good light, the AF is fast enough to AF-S moving targets, if they're also slow enough.
Try tracking something faster than a rock, though - it'll remind you why you bought that DSLR.
I do feel for your AF woes, though - Been there & done that, though not to this degree, and it can be incredibly aggravating, especially when you start using a CDAF rig that has near 100% accuracy.
I'm certainly not looking forward to this BS when I get back into DSLR territory - fingers crossed.
Also, it's quite possible your AF module could be mis-aligned, which would in fact throw off AF on certain points, while being sharp on others (also, you're assuming your lenses aren't decentered and sharp uniformly across the frame).
Since you mentioned Olympus, that reminds me of yet another awesome feature of their older E-5 DSLR. Not only would it MA zooms and apply varying levels according to zoom level (so Canon's zoom MA is actually way behind the curve), but you could apply different MA values to every AF point. Ridiculously awesome, though I'll be damned if I ever had the patience for that!
Good luck and I really hope you get things situated.
