Benro 150mm Filter Holder for Canon TS-E 17mm 4.0 L<\/figcaption><\/figure>\n

I am always looking for new photography related accessories that might be useful for what I do. Furthermore when holding a workshop or going out with other photographers I constantly have a closer look at other equipment that I wouldn’t have bought myself to see how it works in the field.<\/p>\n

Unfortunately every once in a while I come across a product flawed by design (sometimes deeply) and then usually the Team of phillipreeve.net has the misfortune of listening to my complaints.\u00a0They suggested to make a series out of this so others might be warned about these products. This is one of these flawed products.<\/p>\n

Benro 150mm Filterholder for Canon TS-E 17mm 4.0 L<\/h1>\n

I just recently acquired a Canon TS-E 17mm 4.0 L (great lens, there will be a review one day) and being able to use a polarizer is mandatory for me in landscape and architecture photography (yes, even on lenses this wide as I need it to eliminate reflections on foliage and windows).<\/p>\n

Researching my options I came across this Benro holder and a dealer on ebay who had it on offer for a very good price.
\nBenro is pretty new in the filter(holder) business but I nevertheless decided to give it a try.<\/p>\n

Something positive up front: the holder comes with a rich accessory kit featuring a 95mm adapter and a 95->77mm Step Up ring so you will be able to use it on most of your other lenses as well.<\/p>\n

The holder consists of two parts, one base part that attaches to the lens cap bayonet of the lens and then the actual filter holder which is held in place by two screw knobs.<\/p>\n

These two screw knobs are the problem of this holder. Underneath are washers that are used to clamp the holder to the base part. As I intend to use a polarizer I obviously want to be able to rotate the holder. To rotate the holder you need to loosen both screw knobs a tiny bit.
\nThe problem is: when rotating the holder – due to friction – you will tighten (rotating anti clockwise) or loosen (rotating clockwise) these screws.
\nIf they get a little tigther the holder simply gets stuck. If they become too loose it will also get stuck (jumps out of the groove) or even worse: your holder including filters will drop.<\/p>\n

In this video I made you can see the holder easily gets stuck:
