The Canon EF 35mm f/1.4 USM L is certainly an impressive piece of engineering but it struggles a bit on full format DSLRs - at least technically. The center resolution is excellent straight from f/1.4 but the borders and extreme corners are soft here. That said it is certainly capable of delivering images with a very shallow depth-of-field and that's the primary point of this lens after all.

The EF 35mm f/1.4 L is an excellent fast lens for wide field astrophotography and performs optimally at f/2.8. It is also a fast focusing lens when used for general photographic purpose. Performance is excellent at f/2 for non-astro photography.

As you would expect from a prime lens, especially one with Canon’s famous L suffix, the optical performance was good. You will see from the chart that a gentle curve is achieved with no wild jumps from one stop to the next, always the sign of a well-produced lens. It also manage to start from a decent wide open performance, showing that it has not been pushed beyond what it is designed for.

The Canon EF 35mm f/1.4 L USM Lens is slightly soft at f/1.4, but useable in my opinion. There is a noticeable improvement by f/2.0 (quite sharp). Some vignetting will be apparent to Full Frame and 1.3x FOVCF DSLR users until stopped down f/2 or so. Any distortion present is very minimal - FOVCF body users should notice none.
