hey guys!
i'm wondering which bag you'd recommend for me to use. i want something easy to use, so i can switch lenses without having to put my bag down, something that won't be too heavy (my shoulders are normally really tight, so i'm a bit unsure about a shoulder bag with so much gear) and something that'll offer good protection for my stuff. i'm debating between the crumpler 7MDB or the slingshot 200. the slingshot seems to be better for distributing the weight better on the body, but it doesn't seem like you can easily switch lens without putting down the bag first (from what i understand, if you have the bag on, and open it fully, the lens would fall out!! yikes).
this is a list of my gear so far:
canon 40d
17-85mm IS
50mm 1/8
580ex II
55-250mm IS
70-200mm F/4
i'm debating on either getting rid of the 55-250 or the 70-200mm right now.
which bag would be better? thanks!!
