65mm lens on Shen-Hao 4x5 ?

[Alexz]

My Shen-Hao 4x5 is now clearing at our Customs, hoping to release it within few next days.
The question is dealing with wide angle choices.
I know, 90mm would be my natural choice for 4x5, and 28mm lens is what I used to as widest one for 35mm which is fine for me (perhaps though 24mm would not be lesser).
However, besides of 4x5 I intend to shoot roll film on Shen-Hao, most certainly 6x9. Since regular focal lengthes for 4x5 produce longer take on smaller formats, I thought adding some superwide (in terms of 4x5) will solve the wide angle coverage for 6x9. I.e. using 65mm lens will produce about 28mm equivalent (of 35mm format) on 6x9.
The question is whether Shen-Hao 4x5 will handle 65mm lens allowing movements and full raneg focusing ?
What I was offered is Rodenstok Grandagon-N 65mm/4.5 for 750 US$. The price sounds to be a bit high probably (not sure), what do you think ?
Also, what is the coverage of this lens (circle) ? I suspect it may be very limited for movements on 4x5, however perhaps better on 6x9 ?

Will be glad to hear your opinions. (and Shen-Hao experienced wide angle users in particular )

Alex, the shortest lens I have in my 4x5 bag is a 65mm Nikon. It just barely covers this format, but it does. If you don't have a bag bellows, your movements will be restricted, but it will allow plenty of movements in 6x9. Hopefully the 6x9 back you have won't have the film plane too far back from the normal position of the ground glass. I'm not overly fond of the lens, as I don't have a center filter to go with it and the fall-off at the corners is severe with this focal length (more than 1/2 stop at the corners in 4x5). tim

A 65mm lens will work and focus fine on the Shen-Hao. I have the bag bellows and even with it the movements are restricted by the camera body with the sort lenses. Of course the movements are restrivted more with my 65mm Super Angulon because of lack of coverage.

Thank yuo guys.
Tim, you rouse another issue I forgot to ask about dealing with 65mm lens: light fall-off and the necessity for center filter. Does the 65mm/4.5 Grandagon-N needs center filters to allow adquate movements ?

The center filter corrects for light fall-off effects as you move towards the edges of the image coverage circle with any wide angle lens.

Center filters have no effect on the size or resolution of the coverage circle - hence no effect on camera perspective control movements.

Thanks. That is what I meant to asked about.
The question now is whether one indeed needs center filter for 65mm/4.5 Grandagon-N for 4x5 to exploit the movements that it allows, i.e. how severe is light fall-off in practice.

Can't help from experience, but Paul Butzi has Rodenstock data sheets on his website here: http://www.butzi.net/rodenstock/rodenstock.htm
