Well I've just got the opteka 6.5mm and i was wondering what the best iso/aperture/shutter settings are to for shooting skateboarding. I usually shoot skating at around shutter 1250 with iso 100 on a sunny day but the fisheye cant compensate for such a high shutter. what should i use?
 
well only increase the iso if you have to, example: your at f3.5, shutter speed 1/60th, and your underexposed. try to keep your shutter between say 1/60th and 1/200th to be on the safe side, going to high will give you ugly strobey footage (i know people prefer that look sometimes but for skateboarding it pretty much never looks good). set you aperture accordingly to get the proper exposure.
 
given that this lens won't accept ND filters, it's not easy to shoot in daylight with it...

* try to get shutter close to the 180º rule to avoid excessive strobing (1/50s for 24p, 1/60 for 30p, 1/100s for 50p, 1/125s for 60p)
* set ISO and aperture to get correct exposure
* if you can't lower ISO or close down your lens any more* and still are overexposed, deviate fromt he 180º rule, as little as you can

using technicolor cinestyle (with contrast=-4) as your picture profile will help preserve the highlights
if you have a camera that will run magic lantern, use it, and check your zebras


*: you should test the lens to see where diffraction starts being a big problem (i.e. how much sharpness you lose once you close the iris beyond f/11 or so)

when you say 1/60th for 30p.. on the t2i is that just literally the shutter speed that says 160?
Click to expand...

Usually shutterspeed is displayed as a fraction but on the Canon DSLR's in video mode shutterspeed is displayed with just the denominator (the number on the bottom of a fraction). So 1/60th is displayed just as 60, 1/100th is 100, 1/250th is 250 etc.

160 Would be equal to 1/160th (is that even an option? I can't be bothered checking right now...).

If you are shooting in 720p60 for slow motion, do not be afraid to bump the shutterspeed up a lot higher. 1/500th or so is fine if you are going to conform the footage to 24p or 30p in post.
