Tim,
I replaced my Nikon D70 DSLR with the GH2. The camera and especially the lenses are lighter and more compact. For my Belize vacation, I took my Panasonic GH2 and lenses in a LowePro Slingshot 202AW. Loaded into the 202AW was:
Pany GH2
Pany 100-300
Pany 7-14
Pany 14-140
Pany 20/1.7
Olympus FL36 flash
Ultra Dot red dot sight and flash mount
BlackRapid sling strap for GH2
3 GH2 batteries
Rode Videomic Pro shotgun mic
Zoom H1 recorder
Redhead windscreen for H1
Passport ColorChecker
Gary Fung flash diffuser
Panasonic remote trigger
Extra batteries for flash
GH2 raincoat
Total weight including LowePro bag: 11.2 lbs.
The Anhinga and most of the shore bird shots were taken with the 14-140. Most of the land bird shots were taken with the 100-300mm lens. The 35mm equivalent focal lenses are approximate 2X. I.e., if using a 35mm film camera, the 100-300 lens would give a 200-600mm field of view. Of all the lenses, I love the 7-14 the most. Awesome lens.
Overall, I'm very happy with the camera.
Regards,
Dan.
