I'm sitting on this question. I want a fast telelens. Pentax doesn't make them at the time. There are some options, not all of them as handy. I want to use them for sports, and want the f2.8 since I also want to use them in a venue-arena.
Options:
- Pentax FA*300mm/f2.8, this would be nice, but I never found one, and I think maybe outside of my budget.
- Pentax A*300mm/f2.8, this is a manual focus lens so there are limitations in use. I do a lot of prefocus, so there is a way to work around it.
- Sigma 300mm/f2.8, this is a rather fast AF lens, but there is no manual overwrite in focus, so if it missfocusses then you have to start again. Not HSM, since those are only for canikon.
I have a possiblity to perchase the Sigma and the A* at the time. Wich one to choose and why? Or something else?
Some pictures I take wit my current lenses. So with longer telelens there will be different views that I can't make at the time.
I use an old Nikkorlens at the time that works with an adapter as a 375mm/f5.6 manual focus and no connections. Justin Henin at a WTA tournament.
Volleybal, this was with K-7 so I used FA*85mm
Red Bull Crashed Ice with DA*50-135mm
So I hope some input on my discionmaking process.
