I’m thinking of getting a 210mm f/5.6 for my 4x5 camera and assumed that the brand would be immaterial: SK, Rod or even Nikon. ButI think this may not be quite right. From spec sheets, looks like the Sironar has a smaller diameter rear group so is less likely to foul the bellows. What do you people prefer for your 4x5 field cameras? THanks.
