I recently tried out a Fastpack 200. You might get all the equipment inside, but I doubt it. The compartment for camera and lenses is quite narrow in the vertical direction (camera/lenses are stored horizontally) and the 70-200 with the lens cap reversed will take up a lot of the space, so you may not be able to get the 24-70 and 17-55 in as well. There is plenty of room in the upper compartment for the flash and other accessories..

You should be able to fit everything into the Fastpack 300. However, since you will have the camera round your neck most of the time, how about a more conventional ruskcsack like the Lowepro Mini Trekker. That will certainly take all of your equipment..

If you want any other opinions try the Canon SLR Lens forum - it is your lenses which will determine how big a bag you need.Chris R..

Oh, that's true... That's probably a more fitting section for this questions... sorry!..

I will be wearing the backpack during the shoots (outdoor portraits),so I can throw the lenses back into the backpack quickly. Camerawill be on my neck all the time except when I am storing it at home..

I hope you were joking about throwing the lenses back into the back pack! I wouldn't even so that with my brothers stuff!.

Maybe what you need is a bag for general gear and a belt pack to hold a couple of lenses that you are using. That way you can slide them in out.If you think that makes sense, then you must have read someone else's post!..

So~ Can I buy this Fastpack 200 or do I need to go bigger? Thanksfor the help!.

For the type of shoot you describe, I think a backpack is the wrong kind of bag..

Look at a LowePro Nova 4 or Nova 5..

Well, I am not gonna THROW the lenses... ha ha! But you may be right, I will need one for transporting, and one for during the shoot... Hmm... more money...  ..

Hmm... I just did, and I have decided to stay away from that kind because I don't feel the one shoulder strap is very secure... I have a small camcorder bag like that, maybe I will try it with that first... Still, if I was to carry $1000+ worth of equipment, I want two straps. This is also why I am not getting the Slingshot... Thanks though!..

Oh.those straps are tough!.

My Nova 5 is the camera bag I use when I fly somewhere.it fits under the seat perfectly!.

My LowePro Commercial AW (my everyday bag) is just too big to fit under the seat..

A shoulder bag gives you the easiest and quickest access to your gear..

A backpack, well.you'll have to take it off every time you want something out of it!.

And if it's not zipped up when you stand up.all your gear will dump out on the ground..

I suggest you go to a camera store and look at the bags and try them out before you buy..

I think you are right... But a Nova 4 doesn't look like they are big enough for my XSi + 18-55mm + 50mm + 24-70mm + 70-200mm + flash + maybe light sphere... I don't think I will be carrying my chargers and all the other junk acc with me to shoots, since my shoots are only usually 3 hours max....

I will have to go check it out at the store... Also, the Nova 4 is like half the price of the Fastpack 200... which is a plus in my book!  ..
