The Rapid Filter System is a hinged lens filter adapter designed for all levels of photographers & videographers. Engage & disengage your lens filters in a fraction of a second and keep up with ever-changing light conditions. This standard RFS features a fixed lens diameter and filter diameter. For example, an RFS 67 will have a lens thread diameter of 67 and a filter thread diameter of 67.The RFS & RFS+ are the streamlined solutions to a commonly experienced problem among photographers and videographers. Keep your filter accessible at all times via the revolutionary hinged design and enjoy the fastest way to engage and disengage your lens filters.Both are precision machined from aerospace aluminum and include a built-in light shield, preventing light leak. Choose from either the RFS (fixed lens and filter size) or the RFS+ (integrated step-up) for optimal performance when paired with your lenses and filters.Get the Solution. Get the Shot.

I just found a really cool new use for my RFS+.  Place some sticky double sided tape on the outer surface of the upper ring, then place the sticky side of the ring on top of a sheet of Baader Solar Filter Film that is slightly larger than the diameter of the ring and cut off the excess film.  Voila!  You have a really easy "quick deploy" solar filter for your lens for shooting eclipses, etc.  Much better (and safer) than stacking ND filters.

Versatile product with which you can even make your own solar filter!

Exactly as in the description and well made.  If you really want to have your filter flipping around, then this is great.  It's particularly useful for an ND filter when you are in changing light, such as indoor/outdoor shoots.  It functions just how you imagine it will.

Great

I live in an extremely sunny climate and like the idea of simply raising the lens if it is not needed for the shot as opposed to taking it off and losing it. 

It works well with a circular polarizer or other type of filter that may be needed outside, but not required inside.

It is sturdy and well made. It comes with all the tools needed for adjusting, albeit I have not had to use them. The packaging itself is attractive. The first one tends to take a few minutes to add to the lens, but afterwards it is extremely simple. 

I have ordered several more of these lens mounts and strongly recommend it.

The perfect way to add a filter to your lens

Very nice device.  does what it is supposed to do.

works as expected.

I had a hard time figuring out how to get it on my lens, but once it was on, it worked well to flip my ND filter up to focus and down to use, which saves time and hassle. It seems like a good quality product and I?m happy with it.

Innovative filter ring

Does what it says. Made of metal. Durable. Sucks you have to choose between this and a hood.

Quickly use 2 different filters

Quickly use 2 filters

Excellent product when I use a IR filter. I can easILY flip the IR out of the way to focus then flip is down to shoot. No light leaking

Great for IR filters

Great quality.  Mades using a circular polarizer much easier to adjust by using the hinge and opposite magnetic closure to rotate the polarizer.

Makes Using Polarizers Easier

I was pleasantly surprised at how well this filter holder was built. It arrived in a fancy, round box. Inside, the box contained the filter holder, tools for adjusting, and a rubberized pad for gripping the holder to loosen or tighten once it is on the lens. The price was fantastic too! ($12.95 on a one-day sale)

A nice filter holder!

High quality flip up filter holder that can be used with a filter or like I am doing- with a screw on lens cap in order to have a flip up lens cover.

Excellent product.

Amazing! Just what I needed. The material and overall build quality are impeccable! I highly recommend it for photo/video work! My only regret is not having purchased it sooner!

I LOVE ALTER!

I am seriously in love with the Alter RFS! I do a lot of run and gun work and it is so nice to be able to quickly put my ND filter up and out of the way. I use a Ronin S and it doesn't effect the balance of the rig at all. Definitely recommend.
