Huib,

The Lee filter system that I am familiar with has 100mm square 
filters (oblong in the case of grads but 100mm wide). Please remind 
us what the filter diameter is on the 90mm SA f5.6

The easy way to tell if you are going to have a vignetting problem is 
to try the filter system out on the camera with the lens of interest. 
Take the camera back off see if you can see the edges of the filter 
holder.

For extreme wide angle lenses I have trimmed the front of Cokin "P" 
size holders in the past to give only one slot rather than the normal 
two or three.

It seems likely that you are trying to find out the answer to your 
question before buying so this may not help too much - well at least 
I tried :-)

Inany event, it is a lot more cost effective to use the Lee or Cokin 
type systems with adaptor plates and makes your back pack a lot 
lighter if you have lenses with various filter thread diameters.

Cheers,
