I bought this bag awhile back to carry a large medium format system or my 4x5 kit but never really used it. I went back to my time tested older bags. I bought used in "like new" condition or at the least ex+ condition. I compare it to a Tamrac 612 Pro System bag I use to have only slightly smaller. It could be a wonderful bag for any format - I just don't use it. Outer dim.- 18x10x10…..inner dim.- 17x9x9 inches. $80.00 plus shipping. PM with questions.
