8x10 lens with 1/500th shutter speed ??

[chris jordan]

Hi guys, I'm collaborating with a friend on a project involving some aerial color photography with an 8x10 view camera. We would like to use a lens in the 300mm range, and to avoid fuzzy results due to camera vibration, we need a lens with a 1/500th of a second shutter speed, or even faster if there is such a thing. No camera movements would be necessary, but it would need to be a lens that gives a sharp iamge from edge-to-edge even if the aperture is fairly wide open due to the fast shutter speed.

Does anyone know of such a lens?

I'm sure you jsut sit at home thinking these weird lens questions up... :-)

I think that by nature, a lens with a 1/500 sec. shutter speed will have to fit in a fairly small shutter (unless we're talking about some exotic and expensive shutter), so if it's 300mm, the tradeoff will be that it's too slow to shoot at 1/500 sec.

What do the 9.5" square format arial cameras have? Why not just use such a camera made for the purpose?

Why not the Aero Ektar?

Hi Chris,

The only lens in that focal length, mounted in a Copal 0 shutter with a 500th of a second shutter speed is the Fujinon 300T (tele). However, it won't cover the 8x10 format. On the other hand, a Fuji 300C or a Nikkor 300M, will cover 8x10 at infinity. A copal 1 shutter with a top speed of a 400th of a second should be fast enough for aerial color work. You'll need plenty of light. Their maximum aperatures are f8.5-f9.0. Are you sure you want to use an 8x10 for the project?

Checkout http://www.ken-lab.com .

They sell and rent gyro-stabilizers for cameras to do such things as aerial photography. One should be able to use their large unit and a Copal 3-mounted lens for sharp photos. They brag of up to one second handheld shots being possible.

Use the right tool. Trying to do a specialized job with general purpose gear that happens to be at hand can be a bad idea. Rent a proper 9x9 aerial camera with a f0cal plane shutter, USCGS certified lens, and image motion control.

Doing a specialized job oneself is also often not a good idea. Why don't you have the job done by an aerial survey service?

Because I'm betting aerial survey services don't make art... !

a while back one guy posted about rigging a graphlex focal plane shutter up front near the lens. As you may know these go to 1/1000th sec...
