[3 x 2.95 x 0.8"] I love the fact that this stays in the camera and does not have to be changed with the lens. Saves lots of $, and helps with image quality. And the quality looks really great. I'm not noticing any color issues. I'm also not having any looseness issues. It's nicely snug, but easily removable. I was concerned after reading another review, but this copy was able to remain in place with the camera pointed straight down during lens changes. The ND 8 is the lightest filtering, but it seems like plenty for most situations. I'll be ordering more for my other cameras, but most likely all ND8 because unless I were in extremely bright light this seems like the sweet spot for me.

[0.085 lb] These are incredible because they can be used with any lens. Many people seem to be having issues with how they fit, and that's really because they aren't installing them correctly. The Kase text needs to be facing the sensor, if you put them in the wrong way, they are loose. If you put them in correctly, they fit nice and snug, on all Sony full frame cameras. I have the a7s III and a7 IV and they are not loose at all. I have a tech channel on youtube called Doubt Me Tech and I made a review/tutorial video on this set and you can see how to install them correctly. These are awesome and highly recommend them.

[IR Control] My friend has these and told me to get them. So I did no questions asked. I can't wait to point my camera directly at the sun and not be blinded. I think that's all I can ask

[3 x 2.95 x 0.8"] I have never used an ND filter before. Novice review: Every youtube vid I've seen on ND filters talk abut color shift or color cast. I don't see it here!
I'm thrilled to use 1 ND filter for all of my different lenses.
Examples probably do not truly highlight the benefit of ND filters but it was my first forray.

[IR Control] Shooting with the A7S3 @12800 ISO almost performs like a converted body for BW photography. I get nice results without slow shutter. Also love that I can use this filter with any lens. It really shines with the Sigma 14 1.8. Great entry point for IR if you have the a7S3. Check the customer images to see a few shot results.

[3 x 2.95 x 0.8"] This plate is so helpful for the Sony cameras. It has a small lip on it to prevent the camera from drifting when in the vertical position on the tripod. This is a must for Sony cameras. Bought two ( one for each camera

[3 x 2.95 x 0.8"] Glass seems to be high quality. Works as expected.

[3 x 2.95 x 0.8"] Fits great in my A7iii. Easy to install. Solves my dust issues without affecting IQ or autofocus.

[3 x 2.95 x 0.8"] Filter really makes a bold difference in astro imaging. Noting that the lens sun hood doesn't fit over the knurled edge of the filter. I can live with it since a sun hood is rarely needed at night... if I were to use this filter for artistic reasons during the day I might have another thought

[IR Control] This filter fits the A7R IV perfect. Be sure to place it in with the letters towards the camera and press the top until you feel the click. I have had no issues with it. It does a good job reducing the yellow in night photography and making the colors of light more realistic. Hard to beat for the price and convenience of using it with any lens.
