Picture quality was verleichbar with the "L" ??

Although as yet no way had the 50 / 1.2L .... but try to soooo much better
as the little brother here, it may not be.
I use this lens very happy at my new 5DM3 and just as happy at the 1DMK. 4
Both cams eye candy in terms of image quality.
The AF is fast enough thanks to USM and also sits precisely.
Weight pleasantly light and therefore also good haendelbar.
Low-light indoor shots even by candlelight are possible field easily.
That's all there really is not to write.
The price is acceptable for that quality in each case.
Lens Hood is primarily for outdoor scenes egg must!
Unfortunately, this is - on wages separately - as with all Canon L NON-products.
From me a full purchase recommendation.
