RECOMMENDED by industry expert TITO FERRADANS in this review:


Diopters are an increasingly important part of the modern cinematographer’s toolkit. They allow any lens to focus closer while maintaining its character and can be particularly useful when shooting close-ups requiring a shallow field depth. Diopters are especially useful with anamorphic lenses, which usually have limited close-focus abilities, but can also be used with spherical lenses to significant effect.


The Simmod Lens 95mm screw-in +0.5, +1 and +2 strength diopters are manufactured to the highest tolerances using premium grade Schott BK7 glass with an index similar to cine lens elements. Each side of the lens is coated with 14 layers of Multi-Resistant Nano Coating (MRC), which, combined with high-grade glass, results in a diopter with exceptional performance.


Each diopter is built for professional use, with the ring constructed of electroplated brass. This reduces the likelihood of the ring getting jammed into the lens. Inferior filter rings often use aluminum, which is softer than brass and can deform, is more likely to pick up dirt, and can result in galling or binding with the lens thread.


The diopters are 95mm threaded front and back, which allows for the addition of further filters, or stacking for transport. This versatility in mounting, combined with relatively light weight, makes the Simmod Lens 95mm Diopters perfectly suited to mid to small sized Cine lenses, as well as the vast majority of photo lenses.
