comment Why do electronic shutters expose row by row?
Indeed, global shutter is possible in CMOS sensors. However it requires transistors to be added, which reduces light-sensing area and increases complexity. See Wikipedia.

comment Why does it seem like large sensors are necessary for good low-light performance?
The second sentence should read: The F-number is the focal length divided by the diameter of the aperture. (Wikipedia)

comment Why are SLR mechanisms still prevalent among high-end digital cameras?
You are only half correct - the mirror and pentaprism are full resolution, but the ground glass focusing screen has a limited resolution. This impacts me in practice because when I do manual focus, I actually get more accurate results when using the LCD (without even zooming in) than through though the optical viewfinder.

comment Why are SLR mechanisms still prevalent among high-end digital cameras?
The point about the LCD image resolution is irrelevant, because on an SLR the optical focusing screen has a very limited resolution too.

To add to your paragraph about the mirror box, the specialized autofocus sensors on SLR cameras are much faster and simpler (line sensor) than the autofocus mechanism on mirrorless cameras. This is why sports and action photographers use SLRs.

When you wrote "point-and-shoot interchangeable lens cameras", the current preferred term is "mirrorless interchangeable lens cameras".

comment How long does Canon 7D mk II last in standby?
I can comment about the Canon 6D, which has GPS too. When GPS is disabled and the camera is left on standby, the battery will easily last 3 weeks or more.

comment Canon 750D LCD Display not flipping screen
Try turning off your camera, removing the battery for an hour, and checking again. I suspect this won't solve the problem, so you probably have a hardware problem and need to go to a repair shop.

comment Is a mirrorless camera OK for macro photography?
All right. It's an excellent answer overall, and I like the specific lenses and flashes you listed as evidence for your arguments

comment What's wrong with the Canon EF-S 15-85mm?
@EvanKrall re: first paragraph - actually the 15-85mm is significantly sharper than the 18-55mm and 17-85mm lenses, only lagging a bit behind the 17-55mm f/2.8 "pro kit lens".

comment Is a mirrorless camera OK for macro photography?
This doesn't answer the question... It alludes to principles vaguely, but doesn't give concrete evidence for the argument.

Note that you can always use an adapter to put Canon or Nikon macro lenses onto a mirrorless camera.

comment Does mirror lock-up drain the battery?
For the skilled hardware hacker out there, you could measure the amperage for mirror lock-up compared to other modes such as standby.

Are you trying to combine frames from a Hollywood movie?

comment Automatic perspective transformation for papers on photos
Not sure why you're photographing papers - what would happen if you scanned one of these papers in a flatbed scanner?

comment What is the sound that I'm hearing from Canon EF 24-105mm F/4 L lens?
Indeed, I have confirmed that the 18-55 lens has a silent IS, while the IS on bigger lenses have a click sound and a whirring sound. It's a strange phenomenon.

comment Double exposures straight to a memory card?
I have a strange feeling this might be a troll question, but I could be completely wrong on this...

comment Will a dSLR and compact camera produce the same bokeh output at f/2.0?
While you have an interesting alternate viewpoint, I think the focus of the question is on the amount of bokeh, which is influenced solely by the diameter of the physical aperture.

comment How can I solve the problem of viewfinder lag when shooting video with a DSLR?
Sorry, the point of the question is to not use an electronic viewfinder.
