Hi Rob! Again, I envy your opportunities for combining excitement and photography! I have another idea to help with camera shake. I was talking to an aerial photographer at a trade show recently and he told me about a gyroscopic tripod. Their website is http://www.ken-lab.com/.
He swears by it. Says it will stabilize small, medium and large format cameras (three different models). He uses the medium format model with his 35 mm camera. He shoots from a Cessna 172 by opening the window at 1000 feet and about 80 knots. Uses an 80 to 200 mm zoom lens, usually near 200 mm. He claims that suspending the camera by the tripod is much better than using a fixed tripod that transmits the vibrations from the airplane to the camera through the tripod. It uses a waist mounted battery pack to power it. I'm thinking about getting one to use at weddings. He says you can swing it at about 10 degrees per second and capture a steady image. Just another idea.

The scans I get now are "decent" enough for me, but they could be better. All these terms are relative. :) > The best 35mm lens will have trouble making a really > good 11x14.

See above about "relative". :) I believe you absolutely as far as a "really good" print from the point of view of a Pro photographer. But for instance I have a 30"x20" photographic print (as opposed to inkjet) at home which everyone raves about. It was printed in 1981 from ordinary Kodak 100ASA colour negative film, and taken with a Voigtlander 35mm rangefinder camera dating from about 1950. But I take your point. > It's the lens quality of a poor lens that would show up in a scan.

I was pleasantly surprised to see that some Pentax lenses rated very well on that site. I thought I might have to change cameras to get a better lens. > Rob, plan on spending a moderate amount of money on lenses (you > don't need the most expensive, simply stay away from the cheap > ones). Check out www.photodo.com before you buy a given lens. Makes sense. > Shoot the lens under optimum conditions. If only that were always possible! My photos taken from ultralights are under pretty challenging conditions - no chance of a tripod, vibration and wind buffeting, hand held... but at least the bright conditions make a high shutter speed possible! :) Again, I take your point. > Don't spend your money on a lens based on the > brand name. Good advice - there seems to be a lot of variations in lenses. > Plan on buying a 4000ppi scanner someday. By the time I can afford it maybe they'll be 6000ppi. ;) Thanks for the suggestions. Rob PS Thanks to others who have responded with their experiences of scanning and what impact the lens used has had. Rob Geraghty [EMAIL PROTECTED] http://wordweb.com
