Trying to obtain my first 90mm lens. Had a couple of dissappointments from the auction site, although fortunately managed to get my money back, so I'm thinking of just biting the bullet and buying new.
I notice from the landscape lens review on this site that both John Sparks and Kerry Thalmann chose the Nikkor as their preferred 90mm lens, with no mention of Rodenstock (or indeed Schneider).
I've tried to get some information on the Nikkor, but there's not a lot out there. One of my main questions is the size of the front filter thread. I've got several 67mm filters which I use on my 210mm Rodenstock and also on my MF Rollei lenses. I know the Grandagon 6.8 has a 67mm thread, but what size is the Nikkor?
Weight is not so much of an issue for me, so I just want to know which gives the best results - or indeed if they're as good as each other (in which case I would probably opt for the Grandagon due to it being a tad faster).
