Ya, for sure, this isn't a travel lens, nor a lightweight option. A pancake would have been f2.8 for sure. Lot of difference between f2.8 to f1.4. Either way, like the 58mm f1.4 nikon just released. Some will love it and others will look for other options.... like this sigma.
I guess if you're not satisfied with the current options then that would be a good reason. I believe Sigma is simply updating all their lenses to the new A1 lenses and it was just time to do the 50. It weights a pound and has a 77mm filter thread which will be too big for my liking. I personally would have considered it if it was a pancake design, then it would replace my current 50mm pancake which is an AI-S lens.
