Polaroid is a 37 mm close filter set (+1, +2, +4, +10) is a set of 4 close-ups that can achieve macro-like results, with almost any lens that are paired. Close filters are basically diopter, which places the lens to reduce the minimum focal distance with the value specified on the filter. You can combine the filters to increase their strength and fine -tune their close settings.

- Filters reduce the minimum focal length of any lens so they provide macro -like results
- Strengths of +1, +2, +4 and +10 allow you to change and change the amount of close -ups you want
- Double marching allows combining filters or pairing with other types of filters
