On Pentax 645 135/4 LS for nature photography

[stefano_kustermann]

Hello,

I'd like to know if I must cock manually the leaf shutter every time

I shoot a picture in the LS mode.

My intention would be to shoot pictures of owls flying back to their

nest at night. I need 1/500 or max. 1/250 sec. otherwise the bird

will not turn out sharp. So i need the LS function. But can you

imagine the hustle of climbing up a tree at night after every shot?

Triggering the camera from far away is not a problem because I

managed to adapt the cable switch A to a gate remote control which I

use also with my Pentax LX.

All the pictures I've seen of this kind are taken with Hasselblad

cameras, but since I'm faithful to Pentax and own a Pentax 645, so

I'd love to stick to it.

Stefano, you have the camera and remote trigger in hand. Shouldn't take but a couple seconds to verify how it works.

Yes Frank, I've got the camera and the remote trigger right with me, but I haven't got the 135/4 LS lens, so I cannot try...

As you probably know, you can set the camera in the LS mode only with a LS lens on.

Stefano:

 

Unfortunately for your intended use, the 135mm/f4 leaf shutter lens for the Pentax 645 must be manually cocked each time it is fired. That is accomplished by turning a ring on the lens barrel.
