Canon EF 35mm F1.4L II USM Lens
One of the most popular lenses in a professional portrait photographers bag is a 35mm prime. A good 35mm will render a sharp subject while slightly distorting the space around the subject in a way that many fashion and portrait photographers find appealing. Canon recently announced an update to their wildly popular 35mm f1.4L with the Canon EF 35mm f1.4L II USM. It takes everything professionals have come to rely on with the first version, (such as sharpness, critical focus accuracy, and tank-like build) and made it even more sharp with the benefit of weather-sealing!
Where the first version was sharp, the II redesign is now the sharpest 35mm lens on the market, bar none. For a not-so-modest $300 premium, Canon has turned one of its most popular professional lenses into an absolute MTF, a chart that plots sharpness across a range, champion. Canon has achieved this record by incorporating a new optical element formula that includes their new Blue Spectrum Refractive Optics. This is a fancy new organic element material that features more efficient light refracting characteristics and the end result is a significantly sharper image than what was previously possible.
If you want the crme de la crme 35mm lens, there is nothing currently on the market that can match the Canon EF 35mm f1.4L II USM, but be prepared to pay for the privilege of using it!
