Canon 50mm Lenses
Comparison of f/1.8 - f1/4 - f/1.2 and f/2.5 Macro Lenses

Looking for simplicity and sharpness? There are 4 Canon 50mm lenses to choose from. the 50mm lens comparison will help you decide if one of them is right for you. 

These 50mm lenses give you a "normal" perspective on a full-sized sensor cameras and a medium telephoto equivalent of an 80mm lens on an APS-C camera (crop factor of 1.6x), like the Canon EOS 70D, 80D, and Canon t7i cameras. Okay let's dive in to the comparison of these Canon lenses.

which Canon 50mm lens is best

Although these 4 different 50mm lenses all have the same focal length and angle of view, this comparison post will help you decide which is the best lens for you.

The Canon 50 f/1.8 II

Canon 50mm f1.8 II lensCanon EF 50mm f/1.8 II

This is the most popular and most affordable of this group of Canon lenses.  

First of all, it's the smallest, uses the least amount of glass and the mount is composed of plastic.  

The 50mm f1.8 II lens replaced the original f1.8 lens in 1990.

You have to decide if this is a good direction to go or not. There have been a significant number of buyers who have had this lens literally fall apart after not much use.  

With that said, it still has a high customer rating and outsells the other three lenses combined because it so so affordable. It is a great way to return to shooting with a prime lens at an entry price level. You do run a slight risk of getting an economy lens that might have durability issues even though the large majority of photographers have a great experience with this lens.  

If you are a more serious photographer, you might consider the Canon 50mm lens with the f1.4 maximum aperture and USM-Ultra Sonic Motor.

The Canon 50mm f/1.4

The Canon f1.4 version of the 50mm focal length gives you an additional 1/3 stop of low light level shooting and increased bokeh (pleasing out of focus background).  It's moderately priced and of high quality build.

It has superior smooth focusing over the f1.8 and has more aperture blades, 8 instead of 5 for the f1.8.  For Bokeh Geeks, this means even smoother, rounder out of focus highlights.

The Canon 50mm f1.4 USM also lets you do a quick auto-focus and then manually adjust (It's called Full-Time Manual Focuswithout having to switch the lens to a manual focus setting. The Canon f1.4 investment is about 3 times that of the f1.8 but is still quite reasonably priced for such a sharp lens.

The Canon 50mm f/1.2

I categorize the f1.2 version as one of the Canon specialty lenses.  

You gain only a fraction of an f-stop over the f1.4 and you gain a lot of weight and size.  

It weighs more than twice as much as the Canon f1.4 and costs about four times as much. It is only an appropriate buy for those Canon shooters that require or desire shooting at those very low light levels frequently or need the ultimate in shallow depth of field and bokeh capabilities.

The Canon 50mm Macro f2.8

Canon 50mm f2.5 macro lens

The Canon 50mm f2.5 Macro is the shortest macro lens that Canon offers. It's physically quite a bit longer than the other 50mm lenses.

The 50mm Macro doesn't don't get true 1:1 macro without an adapter, but it does get real close.

The magnification is not as good as if you fork out the extra money for a longer macro lens like the 60mm Canon f2.8 or the Canon EF 100mm f2.8.

Most macro photographers prefer to manually focus and an f2.5 lens isn't ultra bright for critical focusing.  It's minimum focusing distance is about 9 inches which is twice as close as the other three Canon 50mm lenses discussed in this article.

It's also of course the most affordable Canon macro lens you can own.  The biggest advantage of using  a lens like the macro f2.5 is that you have a good general purpose 50mm lens that doubles as an adequate "almost macro" lens still quite capable of shooting some great close-up photos.

what is a 50mm lens used for

These 50mm lenses are good for general purposes. They're all good for you to use as an introduction into the world of prime lens photography. They can be described as a good walk-around lens.

5 Benefits of Using a Canon 50mm lens

Why buy one of the Canon 50mm lenses?  

  1. PERSPECTIVE. The 50mm focal length gives you a very similar perspective to the one you get naturally with the naked eye. Prime (non-zooming) lenses get you out of the lazy photographer mode of standing in one spot to compose your photo.
  2. FAST. They all have a nice maximum wide open aperture (f/stop number). This means they are great for low-light photography. You can shoot using natural light without flash in dark situations, nighttime photography.
  3. BOKEH. That's the pleasing quality of the intentionally out of focus background you want to get when you want your subject to stand out, to visually separate from the background. This is very desirable when you're shooting portraits. The f/1.8 gives you very good bokeh. The f/1.4 gives you great bokeh. The f/1.2 gives you outstanding bokeh.
  4. QUALITY. Because their lens designs are simpler than zoom lenses, it's easier for the designer to come up with optics in the 50mm lenses that give you crystal sharp, high quality images.
  5. SIZE AND WEIGHT. These Canon 50mm lenses are relatively small and light. That makes them easier to handle, carry, and perhaps you'll be more likely to shoot your Canon. The more you shoot, the more you improve, and the better your photos come out!
