I've always had a 50mm lens in my bag. It doesn't get a ton of use but it always got used. I'm thinking abut the Samyang f:1.4 MkII. The price seems to be a good price point just wondering about the lens it's self and please don't tell me to get the $2000 Sony f:1.2 I had that happen in another forum elsewhere. It's not in the cards for that price and what I would use it for.
