Not to mention your angle/distance is not going to yeild very flattering photographs.
Perhaps you should just go and enjoy the game, maybe bring your cmaera and a wide angle to capture your friends/family and the atmosphere that you are a part of rather then trying to get "sports" photographs.
There is a reason the pros shoot from where they do.
The game is in the middle of the day. So even at f/8 I should be able to shoot at higher shutter speeds shouldn't I?
As far as just enjoying the game, that's what I plan on doing. I'm not trying to get pictures to submit to a magazine or even a website. Just pictures from my seat that are memories of Opening Day. That could be a zoomed in shot of the players as they circle the field for the Parade of Players, it could also be a wide angle shot of the stadium full of players (I guess you now know I'm not talking about the Royals).
So, if you have an opinion on whether or not this lens will do what I want, I appreciate your response.
