Yeah...I see your points guys. Especially when it comes to cost, if money wasn't issue I'd probably have a Canon 5D and 50 1.2L
I just wish there was option at least, most people I know shoot Canon and depending on what they can afford for example they either have a 50mm f1.8, f1.4 or f1.2L nice to have the options I guess.
And I could care less about ISO research, I never shoot above 400 maybe 800, I'd rather have the shallow DOF personally.
The sigma 30 and 85 1.4 sound great but I just can't get excited about 3rd party lenses for some reason.
