This is a set of the TTArtisan 35mm f1.4 prime lens for Fujifilm X-mount and a Kenko Black Mist No. 05 filter. I used this combination on an X-T2. There is a small amount of dust inside the lens, but there is no mold, fogging, or balsam separation, and it can be used without any problems. The exterior is also in good condition overall, but there is one scratch on the outside of the lens's filter frame. The filter has not been used very often, so it is in almost perfect condition with no scratches. *The Black Mist No. 05 is a filter that gives a cinematic texture, and I personally recommend it because it can be used in various situations from morning to night. The lens has a filter diameter of 39mm, and the Black Mist No. 05 is for 49mm, so a step-up ring (conversion filter) for attaching the filter is included in the set. How about this for a Fujifilm X-mount beginner?
