CMOS doesn't really require UV filter or any color filter for B&W photography, the only use is maybe for IR. 99% of the photographer use filter is for protection nowadays. Personally feel the filter is a gimmick than practical usage. Probably better off with a good tempered glass for protection.for now really like the 13 ultra. changeable lens cap so can swop filter! i hoping for thread mount came true so possible have more lens/filter extension in near future
bit worry on durability of faux leather.
hope to see more image samples from real world users!
