I always look to Kickstarter to see what innovative people are offering me. As a rule, these articles do not come from reputable manufacturers. So you don't have to look for new specials every day. Usually, they copy something else.


Know your age. It is a fast filtering system (RFS) that can turn the lens on and off as needed. Includes Alter RFS RFS, ring assembly, tire key, hex and wrench tools and instructions. It is made of molten aerospace aluminum.


It looks like a ring meeting filter, but that's how RFS stays in place. As a filter twist and strap your camera lens on the front. There are holes in the ring when you try to tighten or loosen the ring to prevent your hand from slipping.


The Alter RFS connects to a universal filter thread that fits your lens and then into an ND or CPL filter (filter thread size 40.5 mm to 105 mm). It depends on the folding system. There are three magnets that hold the panel tight to hold it in place.


You can use the included filter key to secure the ring connector to your lens. You can tighten or loosen the ring handle as you wish. If you let go of it enough, you can hold the fold up or to the side. Make sure you don't overdo it.


Once the ring joint is connected, go straight to the filter you want to install and you can go.


When you roll or rotate the Alter RFS, you can still get the full magnification and focus ring.


In this photo I have a Canon 5D Mark III EF 70-200 f2.8L IS III CPL filter. The CPL filter is a little thick and does not bend completely.


Here I have a Canon 5D Mark II EF 16-35mm f4L IS with Andy filter. The Andy filter is a bit thick so it can stay in the camera lens for a little longer.


One of the key features of using Alter RFS is that you can still use the lens cap to secure filters and lenses, as you do not have to constantly remove the filter. Even if you don't have a filter, you can use Alter RFS to hold the lens cap. When shooting, simply copy it. Take out the cover and keep it in your pocket without putting it in your pocket.


Conclusion In general, change the RFS instantaneous filtering system. It's like any other brand of magnet, but it brings the filter closer to the lens. Easy to install and easy to use.

One of the great things I've seen is the ability to use a lens cap to drive people away. The bend interferes with the fitting of the lens cover. There are also some wedges, but they can be easily adjusted with simple rings.
