I just got lucky on eBay last week and won an auction on a Korona in fairly decent condition. I think it's actually a 5x7 camera but it has a 4x5 back. Anyway, first order was to take my lenses I use for my Cambo and get them mounted on the lens boards. The Nikkor 210 mm works nicely, no problems there. The Schneider 90 mm on the other hand wants to be much closer to the film plane than the Korona will go. It will not focus to infinity and it seems like it doesn't want to focus even 10 feet away.. Don't know for sure right now where it will focus to but I know for sure this lens won't work. On the Cambo it wants the bag bellows anyway other wise its even too close for bellows. You cannot do any movements on the Cambo without the bag bellows. So... now I'm wondering what I can get for the Korona, wide angle wise. I'm a relative newcomer to large format so I lack the benefit of day to day working knowledge on all the different lens offerings out there. So I'm asking the community here to help me out by providing some pointers as to which lenses I should consider. As I am most interested in landscape work I would very much like a super wide, a wide and a normal lens. I've got the 210 Nikkor so I've got portrait lens covered.
