Worth getting the Canon 40mm STM?

[mithrandir]

Anyone have one of these lens and is it worth getting if I already have the 50mm f1.8 MkII?

Initial reviews indicate it is sharp and quick (moreso than the 50mm) and being 40mm seems better for a crop DSLR.

Looking to use it for general walkabouts and to take pics of my little one as he grows.

Thanks for the info cokecan72. (I'm using a 450D as well)

Thanks for the comments guys!

After looking at the thread in POTN...this lens has changed my mind on what it can do!

Thanks for the reminder, I forgot to check POTN (was looking on TP but not much there).
