I would trade my 50A for something optically equivalent but smaller/lighter. The Canon RF 50 f/1.2 is the former, but not that latter (plus...RF mount).
Note that I accidentally put the Sigma 35mm f/1.4 Art in place of the 50mm Art in the RF 50mm f/1.2L comparison images. I uploaded a fixed version of the sans-hood and with hood images, but... it takes forever for the server nodes to propagate the change (I fixed the error hours ago and the correct picture still isn't showing).

Anyway, the RF 50 is definitely larger than the Sigma 50A, but... the difference isn't quite as large as the original comparison shows.
