The difference between my Canon 40D setup *snip* *and* OMD setup.
Apples and pears; APS-C/Full Frame lenses cannot be compared to their m43 mirrorless brethren without understanding the differences.
If you're comparing APS-C/Full Frame
DSLR glass to
mirrorless APS-C/Full frame glass, they're the same. It's physics.
The size of the mirrorless body is nice.
The EVF is nice - but in my OMD and my Fuji XT2 (and a past A6000), the quality of the EVF is akin to a nice VHS camcorder EVF from 1997. I know that EVF's have "gotten better", but ... honestly, they are not
wow.
The ability to see exposure in real time is a
wow.
Controls largely favor DSLR's - bigger bodies = more room to spread buttons out and give some room.
Battery life has improved tremendously with mirrorless - probably closer to 1/3 or 1/2 the life of a DSLR.
If someone is just starting out in photography, the mirrorless options are almost no-brainers now.
But large bodies aren't completely dead yet - feel and user experience still matters to some.
The new Pany's and Olympus' sensor stabilization with or without lens stabilization is a wow.
Features tend to favor mirrorless ( i.e. focus stacking in body ).
Autofocus - the best mirrorless cameras are now matching almost-best DSLR AF systems.
Video - the AF on my DSLR (Nikon) SUCKS. The video quality is nice.
The AF on my Fuji X-T20 is very nice - with good video quality.
Does that new Sony A7 III have low-energy BT ? That thing, on paper, is amazing.
But like every Sony so far, they end up with some achilles heel.
