Nifty fifty was playing up last night, return of the old err01 fault.
So thinking of taking the opportunity to replace.
Something along similar lines...
standard / short tele perspective (I'm on APS-C)
Likely options... Canon 50mm f1.4, Sigma 50mm f1.4, Canon 35mm f2.0, Sigma 30mm f1.4, Samyang 35mm f1.4, not got zeiss money just now, don't mind manual lenses. Think the shorty forty might be at least a stop too dark (and want to avoid duplication, already have an f2.8 zoom that covers 40)
I don't want to hear about how great the 50mm f1.2 or 35mm f1.4 are. I'm not going to buy them, so save your typing.
