I appreciate that the 60D's viewfinder iFCL Evaluative and Live View Evaluative are different sorts of metering that use different hardware (and possibly different algorithms) so might come up with different exposures, but I'm curious as to why such a difference might be affected by the lens.
Both the shots below were taken using a Canon EF-S 18-55 f/3.5-5.6 IS lens at 55mm, f/5.6, in aperture priority mode. The one on the left was taken using viewfinder Evaluative metering (with the viewfinder covered up, of course), where the camera chose a 1.6s exposure. The one on the right was metered by Live View, which picked a 2s exposure.
I see this pattern with most lenses -- viewfinder metering is generally 1--2 thirds of a stop darker than Live View on my camera, for a given scene (I've only really tested for Evaluative Metering mode.) It looks like iFCL Evaluative tries very hard to preserve highlights. It also seems very keen to expose for the sky in any scene where sky is near the active AF point.
Except for with the Canon EF 50mm f/1.4 USM lens. There, viewfinder and Live View metering seem to agree. Same target as above, aperture priority, f/5.6. Both viewfinder (left) and Live View went for 2s:
Anyone else seen this, and know why it might be?
