To this was hardly what to say basically, is only a piece of plastic ...
Fits like a glove to the EF-S 17-85mm IS USM. Since nothing wobbles because nothing stuck and the aperture can be smoothly up and turn off.
An opposite tightening the diaphragm is also possible without problems. However, this is recommended only for the conveyance or protective use, because you can zoom with twisted iris barely.
The inside of the panel is a bit rougher than the outside to reduce the light reflections in plastic.
In a patch panel but it is unfortunately almost impossible to use the originals lens cap from Canon because of this, the handles on the outside.
People with Grosen fingers will have problems there.
For Profox but yes settled a lens cap, in which the handles are on the inside.
This is not made so high meienr opinion. The two clamps hold the filter thread on the lens just outside completely on the last tooth. I would have liked to have liked more food for better grip.
Because you just have to weigh up whether it is hoping to use the high-quality Canon lid, or the more comfortable Profox cover.
All in all, you can not complain for the price but.
