Acrylic Square Business Card Holder

This a great minimalist card holder for the tech or business professional!

I approached this purchase from a different perspective. I had the Lee filter system and on my first trip to Iceland, scratched the acrylic grad filters. I decided to replace them with Haida glass filters and bought both ND and grads so the color would be consistent and tried to use them with the Lee filter holder, which should work based on the reported size, but found that the 100 x 150 grads slipped in the Lee holder if they were vertical. If I applied the Haida gaskets, they were too tight to insert, almost couldn't remove them when i tried to force them in, so that is really a flaw with Haida. So, I decided to try this M10 filter kit. I had looked at this a couple of times but didn't really understand the drop in round CPF until i watched a couple of YouTube videos. Well, this is sooo much better than the Lee holder!! On Lee, you have to screw on the CPF on the outside and it can easily get too tight when rotating the polarizer making it difficult to remove. Also, takes a lot to get it screwed on to start with .... oops, missed the shot! The included CPF in the M10 kit just drops in place, then has a little wheel to adjust the angle. Awesome easy to use, install, and remove. Filters fit great now. Wish I had not waited to try this. Apparently, the older Haida filter holder is difficult to use and I would not recommend it based on the reviews, this is definitely worth the money, and it includes the CPF in the kit. Every once in a while you buy something that is so great you just love to use it. This is my new best photography gadget. Can't recommend it highly enough. Oh, and the color cast on the glass Haida filters is much less noticeable than the old Lee acrylic filters. Lee has a great reputation, but is living in the past. Time to move on from them.

This is a well designed card holder.

Perfect for Contax G2 lenses. Much better than using square type with a holder.

I had to submit a review because of the other review here that says this Matthews clamp (butterfly holder) doesn't open to 1" tube. It absolutely does. It opens to 1" with an extra 1/8" to spare. Square aluminum tube stock can be misleading. Depending on the thickness and ID vs OD, you could easily find a square tube that doesn't quite fit... BUT any normal 1" square tube... does. As for the other points on functionality... it's standard Matthews... built like a tank. So far so good.

This is my first attempt at a square filter setup. The V6 holder is very easy to install and has various step down rings for adjusting to different thread sizes. The included enhanced circular polarizer is ok and kind of limited on the polarizing effect. Definitely adds some weight to the setup but it's worth it.

I have an older P-type filter holder - large but very versatile. I have several round and 5 square filters that I use regularly and bought a new zoom tele and needed the larger ring. Was unavailable at several other photo supply places - can always count on B&H!!

I use this reflector holder to secure a 3-foot square foam core board, balanced along the center axis. It is well made and the counterweight helps with balance. Very pleased with it and would purchase again.

I've been using the canon EF 11-24 square filter holder with the 180mm square filters. The holder is not very secure and dropped the ND64 glass on to rocks (painful added expense) It fits both the canon lens and the 95mm Hasselblad lenses (with the 95mm to EF adapter) I mostly shoot with my Hasselblad and so graded ND filters are not required. These filters for Nikon fit perfectly on to the Hasselblad 95-112 filter adapter which gives me very fast swap times between filters. Love the new work flow, good with hiking, good with cold hands, less expensive and much more usable.

This is a great 100 mm filter holder for square or rectangular filters. It can hold 3 filters. Easy filter rotation with well designed rotation plate. The filters are held firmly, and yet, they can be slid and adjusted easily.
