SJ> used they change owner for less then 2000 Euros. Thats still a lot, but SJ> affordable if I'd really want to.
SJ> But it depends on how it compares to the cheaper and smaller 4.5/300 There is also the possibility of third party 2.8/300 lens. About all of them are excellent, and cost lot less than the Pentax one. It could even have the same cost used as a 4.5/300, who knows... Good light! fra
