You have a Sigma 30mm f/1.4, right? Why not Canon 50mm f/1.4? Was focal length the biggest deciding factor? I’m considering the 50mm f/1.4 and wanted to get your viewpoint.
Thanks for asking, Chris! I figured it be more helpful to post my answer here for all to see.
I wanted a lens that got close to representing the field of view from the human eye (50mm). On my Canon EOS 40D cameara, with a 1.6x crop sensor, a 30mm lens would have an effective focal length of 48mm. That’s the primary reason I chose the Sigma 30mm f/1.4 EX DC HSM lens.
The Sigma 30mm lens stays on my camera most of the time.
Why ditch the Sigma 30mm f/1.4 lens? That specific Sigma lens was meant for crop sensors, so there would be slight vignetting.
Of course, I’ve tried both lenses and I love them. I think you’ll be happy with either purchase.
I hope that helps, Chris! If you have any other feedback for him, please leave a comment.
