Hello to all of you and many thanks for attention.
I am getting used with a borrowed 90mm (on 4x5) before the purchase of a new one. It is a Rodenstock Grandagon f6.8 not MC.
1/ I was surprised how different is the viewed image on my screen from what I knew (with longer lenses such as Schneider f5.6 120 or 150).
In addition to the 1/2 stop difference, the images comes much less evenly lit, in the way that I have to constantly move my head under dark cloth only to compose my shots (focusing with loupe more difficult as well).
Does it come with this particular lens ? Does it come from angle of view ?
As I may purchase a second hand 90 mm, I thought getting a f4.5 would minor the issue. And still hesitating to turn that investment into a Schneider 110 XL, would this one solve the issue ?
2/ Then, it may also come from the focusing screen I am using. (I couldn't even imagine the use of shorter lenses !!! ). It is a Beattie Intenscreen (used on Gandolfi Variant 4x5). Would this screen source the pb of dim viewed image « pain to compose » ? Should I come back to regular fresnel ? — thinking it would increase the problem. Or should I go to another enhanced screen ?
This lens will be the widest of the set (!) for architecture pictures — often in dim light. But I know many other photographers use mainly widest lenses (such as 72, 58 … ) with great results and accurate composition. Therefore I couldn't imagine them shooting with such bad viewing conditions. And I suspect the pb to come from my own configuration.
I would deeply appreciate anyone to enlighten the subject ! I'll be much interested in your experience of shooting architecture with wide lenses. Is it that hard to compose without moving head ?
Thank to all of you.
