Albeit designed with Fujifilm X100VI and Ricoh GR IIIx in mind this close-up lens can be used on any camera/lens with 49 mm filter thread and is adaptable to 52 mm and 55 mm - specially with analog walkabout SLR setups carrying 35, 40, 45 or 50 mm normal-wide lens.

Ocular Perceptual +7 (OP7)

OP7 is an invitation — and a reminder — to look closely. 
Designed primarily for Fujifilm X100V/VI, it is a +7D achromatic close-observation lens that reduces the interruption between noticing something and encountering it close up.

OP7 does not create the richness it reveals.
It makes it easier to come closer — and easier to stay with what you find.
