I need a lens. I've been looking for something with a 300mm or better capability (zoom/prime doesn't matter) that will AF with my 2X converter for shooting surfing (sports action). I cannot afford to enter the Arena of Pro Glass, but I want to at least stand on the sidelines with a monopod and get some good shots.
How much do I have to spend to get a fast enough lens that will AF accurately and quickly without breaking the bank or selling my car? What brand/model? The 2X TC means f/5.6 or better working aperture, or AF is no dice. My budget is less than $1000 but under certain circumstances I might consider finding a way to finance something a little more spendy.
Basically I'm asking for a Secret Weapon. The Bat Lens, so to speak.
"Robin, look! Surfers shredding the sick sets at the beach! Quick, get the Bat Lens! These wicked waveriders won't get away with being unphotographed for long!"
"Holy F-stop, Batman! That guy just did a 360 and his buddy just pulled into a gnarly tube!"
"That's right Robin, even grommets can get barreled and smack the lip if they need to. All we can do is take as many shots as possible and hope they invite the photog to a party afterward. You can stay home and help Alfred dust the Hall of Statues in the East Wing again."
"But Bruce-!"
"No, Robin, I'll be all right- I have do do this alone. It is the duty of a sworn crime-fighter."
"Gosh, Batman, you're a true American Hero."
"I know, Robin. I know."
