STC Optics, an Asian brand that manufactures various kinds of filters, said that clip-in filters for Fujifilm X series cameras are “comingsoon“. In the video above they also show a clip filter for GFX, but so far no indications about it on their website.
As far as I know, STC Optics would be the first brand to release such filters for Fujifilm cameras. Other well known brands include Astro Hutech and Astronomik.
The fact that you attach the filter in front of the sensor instead of on in front of the lens, gives several advantages:
This is a good news for Fujifilm users, because Fujifilm cameras are very good for astro work, due to their superior sensitivity to some wavelengths (like hydrogen alpha, that most of the nebulae are made of) and good ISO performances.
The DJI Ronin S is a very popular 3-Axis Gimbal stabilizer (check out the AmazonUS customer reviews), and so it is no surprise that I keep up getting questions about if it finally will support Fujifilm cameras.
Finally today I can give you an answer. :)
FR-reader Mario (Instagram at @ummario) informed me that DJI now officially said on their forum, they are working on a firmware update to add Fujifilm X-T3 support.
