SVBONY Filter for Photography Broadband CLS Filter for Astronomical Observation Photography CCD Cameras and DSLR (EOS-C)

Fast shipping. Arrived 2-3 days before estimated delivery date.👍🏾Perfect fit for my Canon T3i (see picture). I Did not had to adjust the little brackets. I just slipped in and it fits.😊Do not forget that this can be paired with EF lens. Lends with the red dot (see 2nd picture).Next step is to test it. See if it holds well into the cam and it's overall performance.If only the weather would cooperate.Good service.

Works great with my Canon 90D. Make sure you re-focus because infinity will not work with this filter. Also, I used a little tape in the corners to keep the filter from sliding. Other than that, works great.

No matter what focal length lens, 10-20mm/24-70mm/70-300mm etc, no matter the aperture, or ISO, image stabilization on or off, autofocus or manual... nothing I could do could bring any image into sharp focus with this filter installed. Even with my workhorse portrait lens, Canon 24-70mm L f/2.8, the images are consistently incredibly soft across the entire frame. That means no small details! Reviews that say this filter retains the details, obviously don't care about detail. Without this filter, even my kit lens, 28-135mm f/3.5-5.6, produces images that are far sharper than my L series lenses with this filter. Save yourself the frustration.... BUY SOME OTHER BRAND. Any other brand would probably be better.

Very well made... the pass band is tighter than an Optolong CLS CCD on the green spectrum with more reds... cuts much more the blue and it is an excellent option for fast achromat lenses or telescopes. ORION nebula pic made with Tamron Di Ld at 200mm F2.8 ( a lot of chromatism removed. ) North america nebula made with Samyaang 85m Xp.The picture added of the Dumpbell nebula was made on an Red zone in Mexico city just 56X5 seconds ( without polar allingment ) with ISO 3200 with a 6" Achromat.... I did not has a Bahtinov Mask so.... focus is not very good.

Didn't fit in my Canon T6s even though it claimed it worked for the T6i (exact same camera) sent it back and bought an Astronomik. Had the same problem. Sold the T6s and bought a T7i. Astronomik still wouldn't fit. Went to the neckberds on Reddit, and i discovered you just have to (gently) bend the aluminum prongs out just a hair and it will snap in.Long story short, it would have been a good filter had I actually tried to make it fit.
