Just bought a Canon EOS 1N HS off Ebay with a view to having a camera suitable for landscapes in bad weather. Trouble is I have no EOS lenses left. I have C/Y, OM and M42 adapters for EOS but am guessing any legacy glass I put on this camera will be a weak point when it comes to shooting in the rain? Would I be right in thinking I'd need a Canon L lens for a watertight system? If so, what would you go for. I don't want to spend too much. On a different note, what b&w film would you use? It needs to be C41 process so I can just stick it in Asda for developing..
