Ok, I currently have a Lowepro slingshot 200 and a Lowepro rolling minitrekker.. the latter being used more for storage than anything else.
The problem is, I tend to cycle to work and the slingshot though great for carrying capacity is a bit square for carrying on when on my bike. This means I'm sans camera most lunchtimes when I could be spending an hour taking some shots..
So, my criteria is this:
1) Must be able to carry an EOS 40D with 28-105 f/4 attached, a second lens - either a EFS 10-22 or EF 70-200 F/4 L, and my 50mm f/1.8 prime
2) Must be practical for using whilst cycling
3) Must have space for phone, wallet, mp3 player and the usual junk required for daily life
4) Possibly able to fit a sandwich in, away from rest of camera kit
5) At a push, easily removable camera linings so it can be used as a normal bag
budget, about the £40-70 mark, £80 at a push..
Answers on a postcard much appreciated..
I was looking at the Crumpler courier style ones but there seem to be an infinite amount of varities of those, so anyone with experiences with them please tell me about them.
Thanks!
