Ok so this will be my new lineup in a couple weeks (B&H is closed)

1D Mark III
24-105 f4L IS (only thing I didnt lose)
24-70 2.8L
70-200 2.8L IS

I need advise on a bag to hold this stuff now.

Lowpro makes some good ones. I use Sampsonite and some others for my little cams, quality bags that don't break the bank. Sorry I can't be more help. Congrats!

I have a Lowepro Phototrekker classic. Backpacks are great for walks, but more difficult to take things out.

Congrats. Looking forward to see your new works with the new material!

There are no Borg. All resistance is fertile.

Maybe one of those Lowepro Slingshot bags..?
Great lineup..!

I have the Lowepro AW100 and AW300 and I love them.  Congrats on the new gear, that's a great lineup indeed.

I use a Lowepro Slingshot 200 an have found it excellent. I mange to carry my 350D, three lenses, extension tubes and filters and cleaning equipment in mine and I have very little problem accessing it all.  There is also now a Slingshot 300 which I imagine has a greater capacity.

Ok I am sold on the AW300, it will totaly fit my needs. I had a AW100 but it didnt fit my 30D with grip so I sold it and had a canon bag til it went with the gear. I loved my sling bag before and I think the AW300 will fit my needs perfectly.
