I currently use a Domke F5XC which is fantastic. Really tough and well made, can't fault it. Bought it for use with a 5D with short tele lens attached and was great for that.
With the 1Ds3 I've now got, I've got to remove the lens to get it in the bag. When it's in, it sits wonderfully, taking up the depth of the bag and leaves enough room for a 135 sized lens sat next to it, but I do want to get something in with lens attached.
Is there another Domke bag that'd do what I'm after?
