Sony A700: 690g
Tamron 200-500mm: 1237g
Sony 70-300G: 760g
Konica-Minolta 28-75/2.8: 510g
Minolta 100/2.8 Macro: 520g
Sony 50/1.4: 220g
Minolta 28/2: 285g
Tamron 11-18mm: 355g
Sony HVL-F42AM flash: 340g (not including 4xAA, I think)
Total: 4577g = 10.82 lb
That doesn't include my Minolta 70-210/4 (695g) and my KM 17-35 (430g), which don't fit in my backpack at the moment, but when you add in the weight of the backpack plus extra battery, cleaning supplies, and filters, it's well over 11 lbs. Throw in my tripod (BM 3021Pro, 5.29 lbs) and head (322RC2, 1.5 lbs), and it's more like 18-20 lbs.
I have a smaller shoulder bag that holds the camera plus 2-3 lenses and a flash, but if I travel by car, I'll just take the whole backpack. I hate being without a lens I'd like to use.
