Well, I had a long post ready to go, listing air shows, birds in flight, classic car cruises, etc. Lots of examples of long telephoto use.
But, before I hit 'Submit Reply' I decided to check and see what lenses you already have.
Whoa, wait a minute!!!!
You already have the DA 50-135 f/2.8 and a Sigma 70-200 f/2.8 with lots of letters after it, which probably means it's very good.
To my way of thinking, you're considering shelling out $1,200 to $1,400 USD for 50mm more reach?
Uh uh. Nope, nada, no way, nyet.
For that many buckeroos, getch'a one of the bazookas, like a 300 f/4.0 or 100-400mm rocket launcher. Anytime the little tag has a comma in it, like $1,XXX, you should get more than a 25% increase (over 200mm).
Unless of course, you plan to replace the Sigma, in which case, disregard this entire post.

Wow you just opened my eyes wide about the purchase!
Would giving up the Sigma 2.8 and going to the pentax f4 be a step in reverse?
F4 to slow for indoor sports?
Thanks
Randy
