Originally posted by funktionsfrei BTW: There's a Pentax K 1000/8 on eBay now, in pristine condition complete with crate ... might be difficult to get that onboard of an airplane since it's really uncomfortably similar to a MANPAD, including sights)
FYI: The 1000 f8 weighs in @ 11.7 lb (5290g), that's more than double the weight of the new 150~450 (5.1lb; 2325g). That's the weight of the lens alone. I'm not sure that it's included, but originally the 1000 f8 came with a dedicated tripod that was also a beast. And the wooden trunk case...... Do not think of it as a "walkabout" lens.
