I have nothing whatsoever against phase detection autofocus. In fact, the first autofocus-capable SLR I owned, an EOS 650, back around late 1987, employed phase detection. I’m all for whatever gets the job done.
But what I don’t understand is why proponents of PDAF feel the need to disparage cameras that use contrast detection. Even the Canikonympusonic marketing departments get in on the act with a slew of nose-in-the-air descriptives.
L-mount cameras seem to be the current favorite whipping boy. Trouble is, much of the whipping appears to be at the hands of people who’ve never hoisted an SL2 or an S1R with a native lens mounted. In both cases, I can vouch for speed and accuracy.
Leica goes a step further with its single-point AF, which enables me to pinpoint tiny critters, like the 6-gram Common Tailorbird in the first photo below, through surrounding foliage. Accuracy? You be the judge. In the second photo, even in dark overcast light, the feather details raise a hint of moiré. Both photos are cropped at the pixel level.
Bottom line: each to his/her own choice; but don’t tell me I made a wrong one when the shooting experience and results demonstrate otherwise.
