The gf recently got a new dress, so I got a new lens to match the occasion. After going back and forth for quite sometime, I ended up purchasing a Sigma 50mm 1.4 over the Canon 50mm 1.4. It's kind of a gamble when you buy third party lenses, but I feel like this one paid off. The images are awesomely sharp, the bokeh is very creamy, and the lens feels nice mounted to the camera(bigger/heavier than the canon). I have shot with the Canon 50mm 1.4 multiple times and have nothing negative to say about it, but lets face it, after almost 20yrs, Canon should consider an update:)
Among other lenses considered were the Ziess 50mm 1.4, and the Canon 50mm 1.2L. I had almost decided on the Ziess, but its straight aperture blades and manual focus were a bit of a killer, especially since it retails for $300 more than the Sigma. I briefly considered the Canon 50mm 1.2L, but realized that with that much cash($1350), I could purchase a lens, a tripod, and a plane ticket out west:) This was a no brainer with my current photography habits:)
Here are some images of my wonderful girlfriend Ashley:) All shot with the Sigma 50mm 1.4. And all shot mostly wide open. Enjoy...
