Originally posted by Steinback I have a Crumpler 7 million dollar home knockoff that will carry 2 gripped bodies side by side with attached lenses so long as the body and lens combination isn't longer than 25cm or so. There is additional room for another 2 to 3 prime lenses/ small zooms or a mid sized flash and another lens. I can carry 1 gripped and 1 ungripped body in my Lowepro Slingshot 200 by putting one body with a short lens in the top compartment but only the body in the main compartment is convenient to get at quickly.
Here's another vote for the LowePro Slingshot series, but the 300 series this time. The zipper on my Slingshot 200 ripped out after trying to stuff too much stuff into it. the 300 has a lot more room, i can put a K20 in it with a DA*300 lens mounted, and the upper compartment can easily hold another K20/K10 with another smaller lens. Has a great waist belt to take off the load from the shoulder. I found it on ebay for $79, a great price i think. A fair amount of room for other lens/accessories. I wouldn't want to carry it all day with a heavy load, but it'd be great for short walks and keeping your stuff organized in a car.
