Processing of the brackets is so-so. The polarizing filter looks shaky and rattles slightly when it is mounted on the lens. The filter itself is perhaps interesting for newcomers to understand and try out the effect of a polarizing filter, but can not compete with high end products of its kind.
The holder of the UV filter is OK., Because he does not have to be moved as the circular polarizer.
The Sonnneblende can be relatively difficult to lock, no comparison with the original accessories. The "groaning" sound of my lens when locking the bayonet lock reminds me, and I'm concerned about whether a permanent up and down the diaphragm is good for focusing. But sitting aperture fixed times, makes them what they want.
All in all, I find the set interesting for beginners who want to see and understand the effect of a polarizing filter.
But quality has its price now times and then it has a reason ...
