Get Canon EF 35mm f/1.4L II at B&H Photo.
This page looks at far field performance, a challenging test for any lens, particularly on the 50-megapixel Canon 5DS R, which mercilessly reveals optical flaws.
The Canon 35mm f/1.4L II used here appears to be a “good sample”, that is it shows symmetry in performance across the frame.
Includes images up to 24 megapixels from f/1.4 through f/11, along with extensive crops and detailed analysis.
The results give exellent insights into the lens performance across the aperture range, field curvature, color correction, contrast and sharpness.
I’m prepared to recommend the 35/1.4 L II for Canon users. It is no Otus, but it is very fine lens. For what its price and size/weight and autofocus, those looking for a 35mm lens will want to upgrade to this new model and it will be the AF lens of choice for Canon users. Note that while my Canon 35mm f/1.4L is for sale, I won’t immediately be buying the Canon 35mm f/1.4L II at my budget does not allow for it at present. And while it is a lens I’d like to own, my priority is the unique Canon 11-24mm f/4L.
The Canon 35/1.4L II is likely to be used for people and groups, so I also took a detailed look at an environmental portrait. For me, a 'group' is any number more than myself, since I usually travel and photograph alone.
The discussion should be useful to those that intend to employ the 35/1.4L II for similar shots.
