hello, who knows thie lens?
is't a fit pentax k and very cheap,but about the quality? :

hi
to my opinion,the faj is not very good .i ve tested one (only 30gbp).
the 300 ed is vry good but the price!!!!!!!!!!!

thanks a lot for your quick answer!
as i thinh that a couple of good pics is better tha a long speach,are you agree to send to me some samples made with your own tele

2)what do you mean exactly about rather cheaper and easier to find,because i try to find by google a price for a f300 4.5 but i failed
i only find this reference but not cheapentax smc P-F* 300mm f/4.5 ED IF

3)about the m 4001;5.6 ,i foound one at 140gbp (mmore or less)
is it a good price,normal or expensive?

4The F* 300 1:4.5 can be used to track birds in flight, which is impossible to do with MF lenses, unless you pre-focus and wait for the bird to hit the focus position. In practice, they tend to fly off in a different direction.

Edit: I've just noticed you are talking about sports. You will find it much easier to use an AF lens. These long lenses are very difficult to focus manually and quickly.
i am completely agree with you.i have also a 200mm 1.4 manual focus and i know this problem !! but the results are very good and the lens is very vert cheap(20 gbp)
well,i am waiting for you and thanks

sorry
i have a pentax ist ds and hope kep it for a long time !

as i am new on this forum,it's my first post
congratulations for the quality of this forum and web site

i want to buy a telepentax(m series) and i hesitate between the pentax 300mm and the pentax 400mm f5.6 (mseries too)
i want to use it for shooting sports and landscape mountains.
i had also a pentax 200mm f4 who works very well and very cheap price.

i need to see 3 or 5 pics samples made with each to compare sharp,balance colors ect

thanks a lot
