I am new to LF (and film), and just got into it about a month ago. I have a Toyo 4x5 monorail that I borrowed from a friend, which has a xenar 150mm lens. After using it for a while, I sprung for a Zone VI wooden field camera (Although, I think it's one of the older rebranded Wista's, I'm not sure...) that came with a Caltar II 210mm lens. I really like this new camera, but was thinking of getting a wider lens for it. I plan on shooting a lot this summer in Isle Royale and Alaska, and will have to pack everything with me, so weight is at least a consideration in lens choice. I was thinking of something around 90mm, but I'm really not sure, and wanted to ask for suggestions. Budget is the main consideration, I don't know that I would want to spend much more than $300 on the lens.
