comment What are the effects of using a crop lens with a full frame sensor?
The Sony A7 doesn't have a mirror, but in general, Canon EF-S lenses wont mount on a full frame or APS-H cameras unless you modify the lens, so there's little chance of it happening accidentally.

comment How can I position my marquee from the bottom left of my image?
@NickM yes, you're absolutely right there, for some reason I was thinking it needed to be placed in bottom right...

comment Is there a “special look” to images from large sensors that can't be replicated with a smaller one?
@Hugo is both the design and manufacture that's easier (for a given performance target). Imagine making a really good 100mm f/2.8 that's sharp wide open. Now imagine trying to match that with a format half the width/height, which means designing an 50mm f/1.4 that's resolves twice the lines/mm wide open. Now imagine halving the format again and designing a 25mm f/0.7 that resolves twice the lines/mm again! That's roughly what happens when you move from 6x7 to full frame to micro four-thirds.

@Fumidu stopping down to increase depth of field to match a smaller sensor reduces the amount of light per unit area, thus you have increased noise and decreased dynamic range. Compare DR, colour depth etc. plots of cameras at ISO 400 and ISO 1600.

comment How fast does a sensor cool down sufficiently after a long exposure?
This is going to depend somewhat on the ambient temperature, a good answer would provide values for different temperature ranges.

When you are required to match depth of field, as stated in the original question you must stop down and no longer have any advantage when it comes to noise.

Again, like every other answer here it completely ignores the last paragraph of the question which states depth of field must be the same, this the larger format lens has to be stopped down. Once you do this all the advantages you state, such as better colour depth, disappear. The link you provide is irrelevant as it's talking about a completely different case where you keep the f-ratio (and not the entrance pupil) the same.
