I shoot a lot of plane pics. I swear I can tell the 200mm shots with the smaller lens vs. the goliath. They are always in focus while the 100-400 are 60% of the time. I use the center focus point so I don't get influenced by the ground. Anybody see a problem? I am getting tired of the big$$ not comming thru. I need to do a test , but thought I'd ask.
That 70-200/4 is a damn clear little lens !!!!!!!!!!!!!!!
cheers
