Tiffen has begun adding 39mm filters to its lineup, starting with the popular Black Pro-Mist filters as well as UV protection filters and circular polarizing filters.
Adding a full-blown matte box to a camera rig is not for everyone’s taste, budget, or workflow. Therefore, screw-on filters are often a smarter choice.
Some lenses for APS-C formats (e.g. XF 27mm F2.8 R WR for FUJI X-mount) and other lenses with even smaller sensors to cover use 39mm front filter threads, so there seems to be an increasing demand for such filter sizes.
Tiffen’s extensive array of professional filters is made from optical glass with waterproof and scratch-proof multi-coating, which reduces reflection while maintaining clarity and color fidelity.
These new filters are available via Tiffen’s authorized dealer network or from Tiffen 39mm screw-in filters. Using step up/down rings to fit an existing filter to the thread in question is not always possible or practical, so working with native filter sizes is recommended. Especially since these smaller sizes are not exactly super expensive. The Black Pro-Mist ones sell for $65 each (strengths available: 1/8, 1/4, 1/2, 1 & 2) while the circular polarizer (in 39mm) sells for $20. Lastly, a 39mm UV protection filter is yours for a mere $10.99.
While the black pro-mist, UV, and circular polarizing filters are among the most popular, it would be nice to see more filters added to the new 39mm category. Especially Glimmerglass, Pearlescent and regular ND filters.
