It looks like (fingers crossed) I will be spending 5 days in Costa Rica over Christmas. All I have is a 127mm lens for my RB67. I would very much like have a 65mm and 180mm (or 250mm) to take along as well. I checked the usual suspects (Adorama, Calumet, Helix Photo) and all they rent are RZ equip. I cannot really justify buying the lens at this time, money is a bit tight. (The trip is virtually all on airline/hotel points.) Any help would be appreciated. Jason.
