Mary Square Business Card Holder

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

This is a well designed card holder.

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

great tripod, I use it to take great stills of my poodle mary!

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.

I bought them as a hail Mary... and they fit perfectly on my Benro!

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.
