300mm lens 4x5" landscape

[Fermat]

Hi
What's the best lens 300mm for 4x5" with the following features:
- as much light as possible;
- for landscape:
- as much small as possible
- Black and White pictures
Thanks

"As much light" and "as small" are conflicting.

"Landscape" and "Black and white" are easy.

There are basically two types of 300mm lenses. The ones with a Aperture of 5.6 wich are big an heavy and the ones from f8.5-9. They are super light and small.

F/6.3 Tessars, like the Commercial Ektar, tend to come in larger, older shutters.

The f/5.6 Fujinon-L and Nikkor W come in a Copal 3, which isn't too large.

An f/6.8 Dagor would be a good possibility if you find one in a nice shutter.

My 150mm Topcor with 2x focal length converter is pretty light and small compared to the 300mm 5.6 I use on my 8x10 camera.

What does your teleconverter do to your viewable light?

Fermat, when you say "as much light" are you referring to weight or brightness of wide open focusing?

What can the camera accommodate for a 300mm Lens?
Does the camera have enough bellows and camera extension to accommodate a 300mm focal length lens?
