Yet, such filters usually produce worse results. Note that quality of glass and coatings must be much better than for large front filter to keep same MTF. Also, it places glass with much worse coating (compared to rear element that is specially designed for such) and much closer near the sensor and sensor is quite reflective, so contrast will suffer. MTF will also drop just from the fact that any glass is added. Can check that even variation of glass sensor cover affects lenses performance.

STC’s latest announcement is certain to delight filmmakers and photographers alike as the new range is compatible with not only the Panasonic Lumix M4/3 camera system but also the Blackmagic Pocket Cinema Camera 4K (BMPCC) and the small-yet-perfectly-formed Z Cam E2 4K Cinema Camera. This, fifth-generation series from STC focuses on superior quality with its manufacture, producing imaging results that speak for themselves. With more than a decade of market-leading R&D leading to the series, the structure of these Clip Filters has been improved and optimised to perform better than ever. The Panasonic M43 Clip Filter is designed to sit on the front side of the shutter mechanism and as such, will not affect the Ibis anti-shake function and with its perfectly sealed structure, will also protect the camera’s sensor from dust.

The new Clip Filter Series for Panasonic LUMIX, Blackmagic Design Pocket Cinema Camera 4K (BMPCC) and the Z Cam E2 4K Cinema Camera Includes:

• Sensor Protector Filter
• Neutral Density (ND) Filter​: ND16 (4-stop) – ND64 (6-stop) – ND400 (9-stop) – ND1000 (10-stop). ND8 (3-stop) coming mid-October
• Infrared (IR) Filter​: 590nm – 720nm – 850nm
• UV-IR Cut Filter​: 625nm reduction
• Astro Filter​: Multispectra Multi-Band Interferometric Filter – Duo-Narrowband Bimodal Narrowband Filter​ ​- Nightscape Starscape Filter

One Filter – Any Lens!

As with all of STC’s stunning Clip Filters, the new range of Panasonic LUMIX M43 Clip Filters are completely safe and extremely simple to use, giving users the option to shoot with the lens of their choice. This, by its very nature, demonstrates significant cost savings, completely eliminating the need to purchase multiple filters in differing sizes to fit various lenses. Opening up a world of greater shooting opportunities, the new Panasonic LUMIX M43 Clip Filters from STC can be combined with STC’s traditional circular filters to give creatives a broader palette of artistic and practical possibilities.

Built for Professionals

All STC Clip Filters are manufactured in ​high-quality​ SCHOTT® B270 Optical Glass and​ A2 stainless steel, which is virtually non-magnetic, and finished with double-sided NANO Anti-smudge coating to guarantee excellent water and grease-proofing​ ​performance.

Innovation in Imaging

Since their first arrival, STC’s Clip Filters have been causing a stir within the global image-making community. The brand’s superior coatings and optical qualities are second to none. Couple this with the cost-saving that comes with the product’s ‘One Filter – Any Lens’ message and the result is hard to resist!

William Wu, CEO and Lead Design Engineer, STC, said: ​

“We are excited to watch as both photographers and videographers use our new Clip Filters for Panasonic LUMIX M43 camera systems for the first time. Whilst many photographers see in-body filter systems as new technology, the filmmaking industry has been using these kinds of filters for many years. We believe that producing Clip Filters for Panasonic LUMIX’s M43 mount, and by default, the Blackmagic Pocket Cinema Camera 4K and the Z Cam E2 4K Cinema Camera, we are delivering a perfect solution for videographers who are opting for these small-form camera systems. The benefits are huge, with the ability to ‘pair’ filters, or to simply use traditional circular filters on the front of the lens, coupling with our sensor protector Clip Filter. Whichever you choose, the creative possibilities are endless.”
