I've had a look on here and also on my Flickr groups but still can't find an answer to my query. Currently I'm using a 50mm MK2 which stops down to f1.8 on my Canon 1000d so for live band stuff with no flash I find I might get a shot at f2.8 1/100 sec and ISO 1600 with my 50mm ( shooting in manual so that changes in stage lighting won't throw things off too much, sometimes if I time it right I can even get f2.8 1/100 sec and ISO 800 )
The main issue I have with my 50mm is how it can hunt for focus if the lighting is bad. Reading up on the 40mm 2.8 it seems it's AF is faster and maybe quieter too.
So if I used the 40mm I would lose Aperture under f2.8 and maybe have to shoot at my camera's max ISO of 1600 more. But would the slight gain on focal width along with the faster AF be a plus or will I find myself having to swap back to the 50mm? Also the quieter focus noise is an issue ( is it quieter ? ) as some of the gigs I've shot at are intimate acoustic shows and I hate the noise my 50mm makes when it's hunting for focus.
So basically, does anyone use the 40mm pancake for live bands at ISO 1600 or less with decent results?
p.s. I know I should be using a better camera and better lenses too, but I'm just a hobbyist trying to get into live band stuff and can't afford to buy new gear right now
