+ Extremely cheap (the price already justifies everything fas)
+3 Filter and a bag
+ Scratch resistant mineral crystal
+ Metal edging (stable)
+ Filter can be another screw (to combine them)
-NO Antireflection coating, which is why only in lots of light good imaging performance
real buy rating to lose for infrequent users, as a substitute or temporary solution, or for the holidays to no expensive filters. For the price, nothing is broken.
