comment When determining exposure, is ISO typically taken into consideration secondary to aperture and shutter speed or is it equally as important?
I would say it comes after Aperture and Shutter speed yes, which order THEY come in is dependent on the job/shot required - HOWEVER I will let someone else answer fully...

comment What reduces blur from camera movement more: large aperture or image stabilisation?
(in focus) well for example my Nikkor 50mm f1.4 is quite soft at f2 and wider, and VERY sharp at f8-10 (ish)

sharpness REDUCES as aperture widens - i assume you are referring to motion blur caused my camera movement?

comment Where can I buy IR filter glass?
Good call - not in the UK but could ship - although internationally shipping thin, expensive glass is a VERY bad plan!

comment Why don't most cameras use infrared for focusing?
@MichaelKjörling - they do - but its too dull for the human eye to see.

comment What influences the shape of a lens flare?
Thanks for updating the question, interesting: it seems to be caused by the acute angle to a long telephoto lens as far as i can tell, it doesnt appear to be a vertically compressed frame either. But I'm not sure if there are any other underlying effects caused by this being a movie camera / lens (there could be significant differences in lens and/or shutter design that are inherent to movie vs still cameras) ETA: Die hard - very seasonal :-D

comment What influences the shape of a lens flare?
there are many possible causes including light source incidence angle, aperture shape, lens element shape, and light source shape, can you supply an example of what you have seen so we can try to answer better?

comment Magnets and DSLR's — any problem?
Have a read through this: superuser.com/questions/338641/… Technically I see no issues tbh.

@MattGrum - yes I know, but all IR LED's emit an amount of visible red as well - for example night-vision cameras with IR illuminators, you can see a glow from it.

Is it just red? I was told otherwise but could be wrong, I don't use my SB-910 very much really.

MOST use red / White - my old Fuji used green. Most CAN use IR Assist, many speedlights have built in IR illuminators

No idea, I've never had to have a camera repaired - it could be as simple as a sticky cog or bad motor, or as bad as a mainboard fault. Most likely not worth bothering though, as you have another, and its an old camera anyway.

comment Which is more efficient when shooting weddings: interpolating sRAW or shooting in jpeg?
agreed - but I use a D800... and 4GB CF cards. (and a permanent 4GB SD as an overflow) Personally I like being limited to say 50 shots per card, it makes you think more about each shot.

comment Why is shutter speed usually limited to 30 seconds?
Thanks - I really find it odd that there isn't a simple manual entry mode eg next to bulb where you can just set say 48 seconds and leave it to it. Might be a nice little thing for someone do do in a custom firmware (wink wink nudge :-) - D800 please!)

Adobe Lightroom offers all you will need, and far more :-)
