Hey fellas, I am a noob at least in terms of the experience you guys have and the knowledge you guys ooze out at this forum :thumbup: ...I was gonna go down to the San Fran Bay and try to get some shots of the planes...more details @ www.redbullairrace.com and my gear is as follows: Canon EOS 20D 17-85 mm lens 2 gig mem card Tripod So now I know the lens is rather pathetic, but being a student and all, I really have no means to get the 70-200 mm f2.8 IS USM lens from Canon (which is next on my buying list anyways)...my question to you all is...how do you think I would be able to maximize the quality of photographs I would take of the planes performing high speed stunts? I realize that cloud cover and direct sunlight will definitely change some settings on the camera like WB and ISO. Do you think it would be wise to use the manual mode and fire off a few shots first? Keep that aperture open as wide as possible, use 400-800 ISO and high shutter speed? Would that be a good setting to start off at? And also, would it be more convenient to use Manual focus or Auto focus at that time? Because the focusing system will depend on how fast the lens is, and this is not a fast lens, hence the dilemma. Hope my questions have made sense. THanks a lot for your time.
