Believe it or not, but here you get for little money a properly into the filter thread 52mm matching lens hood made of metal, which I do not at 50 mm at full frame but with the 40mm 1: 2.8 STM by Canon with an APS-C sensor ( Cropfactor 1.6) use. This thus actually a bit too short, but not too bad. Gefält me anyway better than the original part, which is more than the usual one annular orifice tube. which then goes also with a UV filter which would otherwise again exposed to the indirect light. A tulenförmige panel for exactly this focal length would obviously be even better, because the front lens does not rotate, but I have not found.
