Advice on longer LF lenses needed

[henrikfoto]

I would like a longer lens for my Sinar P3 to have a litte extra distance between the object and the camera.

The longest digital lenses I have is 180mm.
I would like a lens about 200-300 mm.

What lens will be best in this category?
And how long will the bellow extention be with a lens like that?

Apo Fujinon 9/180, M Nikkor 8/200, Apo Fujinon 9/240,  and the Apo Ronar 9/300. The bellows extension will roughly have to be the focal length.

Good light!

+1 for the Ronars    240mm is also very good.

And the Ronars are even good with digital 80 mp?

I am using Rollei electronic shutters. All I can see of these shutters are size 0 and size 1.
Maybe that will be limiting for some lenses like the Apo Ronars?

Or maybe it is possible to buy the Rollei shutters in size 2 or 3?

The above-mentioned lenses are all in Copal 0 or 1 shutters. The Rollei controller works only with these sizes, not the larger ones. A good reference for large format lenses is http://www.thalmann.com/largeformat/

Rollei shutters are available in size 0 and 1 only as far as I know….  But the 240 Ronar is copal 1
