Canon EF 50mm f/1.4 USM Review

Canon EF 50mm f/1.4 USM


Despite the fact that it was presented in June 1993, many years after the conception of the EOS framework, it can really follow its roots back much prior, being founded on the exemplary manual center 50mm F1.4 outline of 1971.

In that capacity, it is planned as a “standard” lens for the 35mm full outline position, with a point of perspective offering none of the “perspective distortion” connected with a wide edge or telephoto lenses. Later, with the promotion of APS-C as the predominant DSLR sensor size, it has tackled another part and carries on like a short “representation” telephoto on this configuration.

The lens utilizes a routine optical configuration for its class, and 6 groups with 7 elements, two of which are produced using high-refraction glass.

Focusing is accomplished with an ultrasonic motor system, with full-time manual override; yet not at all like Canon’s other mid-series primes, this is the miniaturized scale USM (instead of the ring) sort. The Canon brand claims the lens delivers an “excellent obscure of the background “, a vital characteristic for a quick lens fit for a high level of subject confinement. The organization is likewise quick to bring up that the lens’ shading equalization is for all intents and purposes indistinguishable to the ISO suggested reference values.

The Canon 50mm 1.4 USM has constantly involved a marginally unstable position in the Canon series, with the F1.8 lens offering striking quality for cash beneath it in the reach. So is this lens an out of date return to the silver halide period, or deserving of genuine thought in the high determination computerized age?

Technical Specifications


At F1.4, the lens isn’t sharp and perform badly, but it enhances quickly on ceasing down, with the middle fabulous by F2, and the corners making up for lost time at F4. Ideal results are acquired in the middle of F5.6 and F11, where it gives radiant sharpness right over the edge; halting down further gives a steady lessening in sharpness because of diffraction.

Chromatic Aberration:

There is something different here. You can see at first look that the modest and straightforward 50mm 1.8 lens’ development adapts to the chromatic aberration amendment superior to the more costly 50mm 1.4.USM To be reasonable we should include, be that as it may, that the hues do not achieve a foul level at any aperture and they can be controlled really well.

What is imperative, when you trade to the full frame is that the Canon 50mm 1.4 USM execution is still great.

The values close to the level of 0.07% may be considered quite low. The chromatic distortion will not be annoying in the photos from full casing reflex cameras beyond any doubt then.

Shading or ”Vignetting”:

At the point when totally open, the vignetting issue is quite serious in light of the fact that the brightness loss from the corners adds up to around 27%. I should quickly include this outcome was come to on a Canon 20D body, so the sensor 1.6 smaller than the 35 mm film outline the tried lens was intended for. We can presume that, on full frame, the vignetting at the greatest aperture will be tremendous in reality.

Luckily, there is some uplifting news as well. On halting down to F2.0 the light falloff is only 10% and by F2.8, it goes under 5%. The circumstance is essentially superior to that of a Canon 50mm 1.8 II which, by F2.0, had the vignetting at the level of 20%.

As we expected toward the starting, at the greatest relative aperture, this lens loses upwards of 72% of light (- 3.7 EV). On halting down to F2.0, the circumstance enhances fundamentally, however, the issue still stays enormous in light of the fact that it achieves 53% light fall-off. Indeed, even the F2.8 opening does not promise the full solace of work on the grounds that the shading still adds up to 30% there.

Just by F4.0 and F5.6, with the consequences of 15% and 11% individually, we can make sure we get pictures with the vignetting level not annoying or even imperceptible.


Distortion on the full casing is around 1.3% barrel. This is towards the top of the line for a 50mm standard prime, and can possibly be obvious in real-world shots.

Distortion on the APS-C format is low at only 0.5% barrel. It is a figure much too low to have any critical effect on true utilization.

Buy this lens if:

You need a quick, general-purpose lens that has a “normal” perspective and it is very suitable for a full-frame camera body.
Moreover, if you wish for a prime lens for portraiture and you have a camera body that has an APS-C sensor, this lens is a very good choice. Additionally, this is a great model that needs no readjustments, even if you fit a polarizer and/or a graduated filter.
Finally, if you are in search of a lens with good flatness of field, this should be your first decision.

Don’t Buy this lens if:

If you are in search of a lens with macro capabilities and close focusing, this may not be suitable for your photography results.
Moreover, if you need high resolution at all focal lengths good edge sharpness and minimal vignetting, then you should probably look into the other 50mm lenses from Canon.


Is the Canon 50mm 1.4 USM for everybody? Frankly, I really trust that I would prescribe it to everybody simply on account of the colossal picture quality consolidated with moderate cost, around $350, and generally not too bad quality. It’s on my rundown of best spending plan lenses. My most concerning issue with the lens is the moderate centering and the absence of an appropriate profundity of field scale.

Give me a chance to explain: lenses ought to work, and they ought to work legitimately. Any DSLR lens will not, however. You will have to micro-adjust them keeping in mind the end goal to accomplish an awesome focus. It is not a simple procedure, but rather once it is done you will be exceptionally content with what you get.

One More Thing.

In real-life usage, however, the Canon 50mm 1.4 USM will probably convey better pictures only for its unrivaled focusing operation. In the event that you are on a tight spending plan you will be more than content with the lower-cost offering, however, in the event that you can without much of a stretch manage the cost of it, the Canon 50mm 1.4 USM will be a more pleasant lens to utilize for your bohemian imagination.
