I'm thinking of buying a case for my 35mm stuff. I hope to fit 2 OM bodies, 3 or 4 lenses. Bonus points of I can cram in my n8008 and 50mm. Is a Pelican 1500 big enough?
It depends on the lenses. I have a Peli 1500 that holds 2 Nikon bodies (FM2n, N8008S), each with a lens mounted (55/2.8, 35-70/3.3-4.5); two extension tubes (stacked) and two lenses (24/2.8, 105/2.8) sitting vertically; and a longer lens (200/4) sitting horizontally. There's room for a pair of Vivitar 283s and a little more. Depending on your lenses, you should be able to cram everything in.
I don't see the point of going shooting with 2 OM bodies, lenses for them,
and an n8008 with a 50. Leave the Nikon gear home and if you don't have a normal lens in OM mount get one. The less you carry, the better.
Please adjust your behavior to fit your screen name. When I first contemplated getting a Pelicase, I got the catalog and laid the gear out on a table, with suitable spacing between the pieces, to find out which size case it would all fit. That's why I have a 1500, not a different model. Go do the same and stop asking questions a person with good sense could ask for itself.
And don't tell me I'm rude. That's not the right word. The word you should use is direct. Blunt will also do.
