To all- Up until now I've known exactly which lens I've wanted to add to my collection, it was just a matter of getting the right price. However now I'm really stuck and indecisive. I need a 50 mm prime for my summer vacation next month. I was really hoping Nikon would have a 50 1.4 AFS out soon but no such luck. My options are the Nikkor 50 1.4 now at $309.00 (Canadian) or take a chance at the Sigma 50 1.4 which is being released in two weeks. I've been really really happy with my Sig 30 1.4 and if the Sig 50 is even close it would be my first choice. BUT the MSRP here in Canada is a whopping $649.00! Why the $150 premium up here just baffles me. Common sense would say go with the Nikkor and sell it if and when an upgrade comes out. The problem is I rarely sell anything and hate the hassle. Another option would be the 50 1.8 at $129.00 as a stop gap. The recent thread by The Dude made me salivate over the Nikkor, Obviously a guy that can great results from a 50 buck P+S still I was really impressed. So any and all help, advice, thoughts would be greatly appreciated.
