comment Is it bad to use old lenses on a new camera?
Agreed, the limit in glass or accessories would be the reason for swapping manufacturers. From the body side there are few chip foundries that can manufacture using the 28µm process (or smaller) used to produce sensors - AFAIK only Sony have that capability in-house (and Nikon use some Sony sensors in their cameras).

comment Why does increasing sensor size necessarily lead to lower silicon wafer utilization?
Possibly related: electronics.stackexchange.com/questions/79874/… which discusses chip yields on silicon which would apply equally to sensors as processors.

comment is there a real difference between “digital” and “film” lenses?
While not a full answer it is a relevant point to mention as the design of the lens would need to account for the spectral shift or vignetting that would occur in a way that it would not need to for film.

comment Mounting Sigma 70-300mm 1:4-5.6 APO Macro Super on Nikon D3200
You could just sell it and buy the Nikon version, that might be the cheapest option.

comment What are Color Profiles and where would I find information on using them properly?
It's worth noting that one of the most respected people in the field of colour management, Dan Margulis, has nothing positive to say about ProPhoto RGB. The thread ledet.com/margulis/2007HTM/ACT06-CM_wkflow.htm contains some interesting dialogue on the subject.

comment Photography Post Processing Using Linux : Open Source : Slideshows to Music
Thankfully (and to my knowledge) the idiocy of using executable code which is ripe for the transmission of viruses and targeted solely at one operating system as a way to produce, store and distribute slide shows or (worse) 'audiovisuals' has yet to reach the *nix world.

comment Why HD broadcast camcorder pictures (still frame from video) more beautiful than DSLR?
Do you think (assuming like for like equipment) there could be something in the use and arrangement of multiple imagers (usually 3CCD) in broadcast equipment vs. a single CCD in DSLRs?

This question might get a better response from video.stackexchange.com

comment What ISO do I shoot Ilford Delta 3200 in?
FYI - Push processing is something that happens when you develop film that has been shot at a different setting than it's rated for. Overexposing (by a stop) is what you'd be doing on your camera if you wanted to shoot for 3200 but could only set 1600 on your metering/camera.

comment Capturing fast moments, such as bullet
@gpuguy - not those specs, no - they tell you how bright and what it connects to but not for how long. Flash duration or speed is often measured as the time the flash takes to get from full power to half power or 10%. Also called t/0.5 and t/0.1 times. photo.stackexchange.com/questions/1620/what-is-flash-duration would be the place to look, and maybe the answer there needs some more attention.
