The Baltimore GP is rolling around before too much longer (Sept), which means it's just about time to start lusting after equipment. Right now in native lenses, I use the kit zoom and the 14 mm pancake on my PL1. Both are obviously inappropriate. I also have a mix of adapted primes and a 100-200 zoom, but I am thinking that manual is not the way to go here, at least for racecars in action. What would you suggest? I'm not necessarily opposed to Lensrentals or purchase. I would prefer to pick up the lens used, so something that's relatively available and affordable on the secondary market would be great. I like cheap and I'm not trying to take pro photos here.
