Wow, I can't believe I have to explain this.
Check the heading up top "Post your camera set up" not "Post your school's set up"
I wasn't pwning your pic, just merely stating that the 200 would suffer a great deal from adding the 2X compared to the 400. The 400 pwns the 200 converted, not my pic pwning your pic. Pics can't pwn, poeple can.
"and then i would just find someone around here with a 600/4 and you would have no chance. ha"
You flat out pwned yourself with the last comment. The 200 1.8, 400 2.8, and 600 4 are completely different lenses for different applications. 200 is solid for indoor, close range, low light, 400 for long range indoor low light, and 600 for long range outdoor. None of them pwn each other on their own because they don't overlap focal lengths. when you convert one to match the other an obvious pwnage will occur.
If you have access to a 600, why didn't you use it when you were shooting surfing?
I would have no chance of what? No offense, but are you really that high in the clouds to think your the only one with access to gear?
Isn't it funny, whenever somebody says "no offense" its always followed by something offensive. ha
