Lol, yeah - he kind of stretched it to get to 10.
The true and honest lists:
Reasons Sony Mirrorless is better than traditional dSLR:
1. Smaller camera bodies.
2. Potentially cheaper bodies and systems.
3. EVF/live view superiority
3a. Focus peaking and magnification
b. chimping right in the EVF
c. judging exposure before the shot
d. face detection
..... and other similar benefits of live view/EVF as opposed to the limitations of a mirror based system.
Reasons that a traditional Canon or Nikon dSLR are still superior to Sony mirrorless:
1. Larger bodies with better ergonomics for users that require it.
2. More complete available systems -- lens and accessory choices, 3rd party support, etc.
2a. Faster native zooms available.
b. Longer telephotos available
c. More fully supported 3rd party choices
3. OVFs remain better for tracking fast action. (slideshow effect of mirrorless)
4. Particularly in the full frame offerings, the dSLRs are more responsive, faster AF, etc. (This is changing, as shown by the A6000 in the APS-C offerings).
Reasons that a Sony mirrorless are better than a Sony A-mount:
1. Smaller bodies
2. Potentially cheaper bodies.
3. No SLT mirror light loss, infringing on ISO performance.
Reasons that a Sony dSLT are better than a Sony mirrorless:
1. large camera ergonomics for those who need or want it.
2. A more complete native lens lineup (though lacking compared to Canon and Nikon)
3. In body stabilization.
4. Among full frame options, the AF and responsiveness of the A7 series is still lacking.
I think this is a legitimate list of comparisons. As I do consider switching, a part of me is very tempted by the A7 at current pricing. I can basically get the A7, new, with the 28-70 lens, for $1500... Essentially making it half the price of the D750. And I like EVF/live view.... I don't dislike a smaller camera.
