35mm f/1.4L USM I

CANON EF 35mm f/1.4L USM I

    • 35mm full-frame Canon EF L-series wide-angle prime.

    • Fast f/1.4 maximum aperture for low light and shallow depth of field.

    • Ring USM autofocus with full-time manual focus.

    • 11 elements in 9 groups with a floating optical system and aspherical element.

    • 0.3m minimum focusing distance and 72mm filter thread.

    • Classic Canon EF L rendering, colour, and contrast.

  • The Canon EF 35mm f/1.4L USM Mark I is the lens that pushed me into my prime-lens era. I sold my EF 24-105mm f/4L Mark I to buy it because I wanted to learn how to “zoom with my feet”. This meant I then only had two primes: a 35mm and a 50mm. It pushed me toward a more journalistic way of shooting.

    35mm is one of those classic storytelling focal lengths. This lens is not the newest or most corrected 35mm, but it has a strong look: contrast, depth, and a useful balance between context and subject separation.

    Its massive flaw for me is not really the softness wide open, but the strong purple fringing. Canon corrected a lot of that with the Mark II version, which, funnily enough, launched in the fall of the same year I bought the Mark I. Not that I would have been able to afford the Mark II during my college years anyway.

    The Good:

    • 35mm is one of the best all-purpose storytelling focal lengths.

    • f/1.4 gives strong low-light capability and subject separation.

    • Classic Canon L rendering with good colour and contrast.

    • Works well for environmental portraits, documentary work, weddings, and travel.

    • Still has a look that feels less clinical than many modern lenses.

    The Bad:

    • Mark I optics are dated compared with the Mark II and modern RF primes.

    • Purple fringing and chromatic aberration can be strong wide open.

    • Wide-open edges and copy variation can matter.

    • No image stabilization.

    • The Sigma 35mm f/1.4 Art has more modern optics, but some EF copies were known for autofocus calibration issues.

    • Get it if you value rendering and low-light feel over clinical perfection.

    • Get it if you want a classic Canon L prime.

    • Overall if you want to stay with EF, I would recommend the 35mm f/1.4 L II.
