comment Difference of auto-focus motor?
I feel there might be demand for a comprehensive answer detailing different technologies, different manufacturers' brand names, etc. The linked questions are quite Canon-specific.

comment Is there really no way to power a DSLR by USB?
Which is to say, it's about power.

comment How do lenses control “projection”?
This is something I've wondered about recently but have been too lazy to ask. Thanks!

comment LightRoom: Any way to get the 'Distortion' effect (far) over 100? Why is it limited?
I'm pretty sure it wouldn't look straight. At 200 it's already overcorrected and more "correction" would just make things worse.

comment Can I use a single RAW file with stacking to reduce noise?
It's worth noting that sensor noise also has a static, non-changing (or more slowly-changing) component - in scientific terms there's both random error and systematic error. The latter can be counteracted by subtracting dark frames and bias frames from the image.

comment Canon 50mm f/1.8 STM vs Nikon 50mm f/1.8G lens?
Downvoted for the biased and irrelevant assertions. The parenthetical clauses add nothing useful to the answer (Full disclosure: I'm a Canon shooter.)

comment Why does it seem like large sensors are necessary for good low-light performance?
Excellent answer. Would upvote twice if I could.

comment Distortion Removal=Parallax Removal?
What do you mean by "parallax"? Accordingly the commonly accepted definition, parallax is the difference in perspective between two viewpoints, for instance human eyes. In a (non-stereographic) photo you only have a single viewpoint so talking about parallax is not meaningful.

comment How does Kelvin for color temperature relate to Kelvin for actual temperature?
@JDługosz I regularly use color temperatures in the high 2000s and low 3000s in Lightroom. Using 4000K for a scene lit mainly by light bulbs would look way too orange.

comment How can I show a slope? Even mountain roads appear flat in my photos
@NicolasRaoul You could use a longer lens to compress perspective; of course this will limit your composition though.

@MichaelClark Yes indeed; the forum thread I linked to has nice pictures that demonstrate this.

Canon cameras very much do use preflashes for focus assist.

comment How does RAW prevent “ugly digital clipping”?
Wait what? Typical RAWs have 14 bits of luminance information per pixel. There are countless of shades of near-white that can be recovered from a RAW even if they by default would all map to 255,255,255 in a JPEG.
