Yes, it is indeed. That monstrous bag was intended for large format cameras, or possibly video. I certainly remember that a video cameraman once asked me what it was and where I got it.

A very silly idea. My posture still tells a sad tale.

But I think I had every focal length prime from 15mm to 200mm and used to carry most of them with me. Odd, when you consider that my vision of the world was almost exclusively wide-angle and that the standard lens was the 15mm. The others almost always stayed in the bag.

And then there were all those flash guns. With lead-acid battery packs.
Plus the 10 roll a day habit.

Ouch.

The only up-side was that occasionally, in London crowds, if someone tried to barge me they got a very horrid shock.
