Been contemplating getting the "new" metal lens hood for the 23 mm f/1.4. Rationally it is not the most economically sound decision but the emotional value is sky high. So, I after a demanding couple of weeks in my studies I decided to reward myself with a little treat.
I can for sure say that that this new hood is such a good fit on this lens and really completes it. If you have a 23 f/1.4, you should definitely get it. Amazing how a little bit of metal can improve the experience and usage so much.
