The EF 50mm F1.4 USM is The canon eos mid-level providing in a variety packed complete of 50mm primes, protecting all costs from the ultra-cheap 50mm F1.8 mkII through to the stratospherically-priced 50mm F1.2 L USM. Although it was presented in July 1993, completely seven years after the beginning of the EOS program, it can actually track its origins back much previously, being in accordance with the traditional guide concentrate FD 50mm F1.4 style of 1971. As such, it's developed as a 'standard' lens for the Negatives full-frame structure, with an place of perspective providing none of the 'perspective distortion' associated with wideangle or telephoto contacts. More lately, with the popularization of APS-C as the prominent DSLR indicator dimension, it's taken on a new part, and acts like a short 'portrait' telephoto on this structure.
The lens uses a traditional visual style for its category, with 7 components in 6 categories, two of which are made from high-refraction cup. Concentrating is obtained by an ultrasound engine program, with full-time guide override; however compared with The canon eos other mid-range primes, this is of the micro-USM (as compared to ring) type. Cannon statements the lens is a 'beautiful, natural cloud of the background', an important feature for a quick lens able of a greater level of topic solitude. The company is also eager to point out that the lens's color stability is almost similar to the ISO suggested referrals principles.
The Cannon EF 50mm F1.4 USM has always filled a a little bit unsafe place in the Cannon line-up, with the F1.8 lens providing amazing value for money below it in the variety. It now encounters clean stress from Sigma's 50mm F1.4 EX DG HSM with its brand-new, hit up-to-date visual style (albeit currently at a far greater price). So is this lens an outdated throwback to the gold halide era, or worth serious concern in the great definition electronic age?
