35mm lenses are in everyones mind those days. There have been some interesting lenses in this range that have been released in the last times. Think Canon's EF 35mm f/2 IS USM (price & specs), the amazing Sigma 35mm f/1.4 DG HSM (price & specs) and as last entry, the manual aperture and focusing Rokinon 35mm f/1.4 (price & specs). The last one a hot one with a price tag of $479. For featured reviews of the Canon and Sigma lenses see here, here, and here. For the Rokinon see here.
