I still havent made a deciscion on a zoom lens I saw some pictures on airliners.net, and I found out they were from 100mm-400mm lens, the author hasnt gotten back to me on the F stop on it. The other thing, the images were huge, extremley clear. I seriously doubt that he has one of those 7,000 dollar lens, so that leads me to believe that he has a normal F stop on his camera. I am looking forward to his reply to see what the F stop on it is. Anyways, I was thinking, Would a zoom lens, with a F4.6-5.6, achieve the speed I am looking for with high speed film, like 800? But the dilema is, I still need quality. I know, I know, I am asking for everything for a decent price lol, aren't we all? So do you guys think I could achieve success with this: Nikon 65 Camera With NIKON LENS 70-300 F4-5.6 D ED (62) Using 800 or 1600 Speed Film Through a dedicated negative scanner. BTW, here are his pics: http://www.airliners.net/open.file/423364/L/ http://www.airliners.net/open.file/423365/L/ http://www.airliners.net/open.file/423366/L/ http://www.airliners.net/open.file/423368/L/ http://www.airliners.net/open.file/423367/L/ Oh, I forgot to mention, In San Diego, all most every single picture I was taking, was on manual. Because it would try and auto-focus while the plane was moving, which meant it never focused. So, if I got a manual only lens, can you get a lower F stop?
