I always thought of the Pentax 60-250mm f4 to actually be quite a brick... Longer than for instance the full frame Canon EF 70-200mm f4 L IS USM, especially longer at 250mm as it extends when zooming, weighing more than 1 kilo (1.2+ kg with tripod mount), that is not a small lens. In fact, that is in full frame EF 70-300mm f4-5.6 L IS USM territory (which is shorther)...
Of course, obviously a 250mm lens will always be smaller than a 500mm lens (not counting mirror lenses).
