以前、少しだけ使ったCANON EF50mm f1.4を再び手に入れた。 cweb.canon.jp キヤノンの一番古い現行レンズじゃないのかとさえ思える。EFレンズの"大粛清"が始まってるね。 標準レンズ=50mm f1.4とするのなら、今浮かぶのはこのEF50mm f1.4かニコンのAI 50mm f/1.4Sかなと思う。 とりあえずどちらか選べば不満は
The EF 50mm f/1.4 is a fixed length lens, and the 18-55 is a zoom lens that can shoot at any of the lengths between 18 and 55. The reason someone would want to get a fixed 50 when they already have 50 covered in an 18-55 lens? Much brighter lens. The f/1.4 lens is 3 stops faster than the zoom lens. Includes lens hood. Canon RF 50mm f/1.2L USM. Sony FE 50mm F1.8. It comes with a lens hood so that you don’t have to buy it separately.

– Canon offers the EF 50/1.4 USM plus the EF 50/1.2L USM (see Gordon’s Canon EF 50mm f1.2L USM review).
