Schneider 72XL vs Rodenstock 75mm/f4.5

[Thingy]

I currently own a Rodenstock 75mm/f4.5 wide angle lens with the correct Rodenstock centre filter. I find that it is quite dim when I am using it for architectural photography and was wondering if I would be better off trying to replace it with a (secondhand) Schneider 72XL instead. I have noticed that those Schneider lenses I currently own (the 58XL and 120 Macro HM) are quite bright viewed through my Maxwell screen. Is the 72XL brighter, or should I just stay as I am and carry on saving up for the Cooke PS945 soft focus lens

Am I going mental, but if your f/4.5 lens is too dim then how is getting an f/5.6 lens going to help you?

Is the centre filter soaking up 1 or 3 stops? Some say that the 72mm is not so critical as to need the filter. I certainly don't have too much trouble with the Schneider 75mm f5.6 although I occasionally use a linear (as opposed to circular) ND grad if I have a lot of shift or rise.

Save your cash for the Cooke

I must admit I kinda assumed people take their CFs off to focus/compose.

The screen makes all the difference.

I've been using an 75mm f8 SA on a Crown Graphic and I can focus & compose easily since I added a fresnel. The screen/fresnel needs to be right for a Wide-angle and some work far better than others. Some manufacturers made different screens for wide-angle use.

Ooops.... That might be a good explanation why I have been having problems...

I'll save for the Cooke instead!

Thanks everyone.

The design of the super angulon means that the light fall off is a lot less than standard lens designs so it is quite possible that a 72XL SA would be brighter than a 75mm of a standard design (assuming the Rodenstock is standard).

However, I'd save up for the Cooke!! and then let me play with it

Cooke PS945 on order with RW. Their first batch have been received and sold; I'm awaiting their next batch. Getting very excited!
