I am looking to purchase a moderate wide lens for 4x5. I have seen some examples of Fujinon lens on ebay - 120mm f8; and the 125mm f5.6. Can anyone with experience of these lens comment on their performance and what is the meaning of the letter code given for the lens - e.g. "W".

My work is general and not specifically architectural, so a lot of coverage is less of a concern, and I would prefer the faster lens for easier focusing.

Thanks for any comments.
