comment What is special about the SENSOR in a Light-field camera?
aaaaaah OK! that makes sense. I was struggling to figure out how on earth you could measure the incident angle of light onto a single pixel. However, lets see if anyone can give more than an "As far as I know" answer...

comment How to calculate the optimal pinhole size?
I'm struggling to figure out how the value of d relates to the pinhole size. I had an answer (based on c=1.414, f=50mm) of 234? if this is mm thats a bit big! if thats nm thats far too small... Should all figures be in nm, mm, etc??

comment What is the difference in purpose between a focal plane shutter and a leaf shutter on a camera?
Ive resisted putting this as an answer - a VERY important feature of a lens-mounted shutter is flash-sync. it is well known that a lens mounted leaf shutter can sync to 1/1000th+

comment Can I manual adjust focus after half shutter press?
I think the best safety advice is "if it doesnt want to turn, dont force it to"

comment What options or solutions exist for photographers who have to use glasses?
I'm short sighted - so wear the opposite of reading glasses (as per stan rogers). The dioptre adjustment works for me although im only a -2 prescription (which is relatively weak) and i have to have it all the way - side. so i dont think anyone who with a strong prescription would get away with it. Of course the available amount of adjustment is camera dependent, but i have found this to be the case on all of my Nikons.

comment Can I manual adjust focus after half shutter press?
I will add that this cant be done on Nikon AF lenses (the ones driven from the camera's internal AF motor (Im aware this was a Canon specific question)
