Best Prime Lens For Portrait Photography

1. Canon 50mm f/1.2

Canon EF 50mm f/1.2 L USM is a weather-resistant lens with the closest focusing distance of 0.45 m and autofocus with a full-time manual option. It packs a 72 mm filter size and an ultrasonic motor.

The 50mm f/1.2 is designed to make the bokeh creamy and the colors pop out. The autofocusing option is speedy; however, it might take you some time to get used to it if you shoot at the maximum opening and target the specific area.

It is wide and narrow enough for a great crop on a full frame. The color rendering is superior compared to the competition. Shooting in dim lighting conditions is a piece of cake thanks to the wide and fast aperture.

Since the lens is super-fast, you will be able to shoot in low light without mounting a tripod. The distinction the lens offers in terms of aperture compared to more narrow lenses is worth the extra money spending.

Although I mainly used autofocus, manual focusing is excellent and does a superb job. Despite the lens’s weight, it feels useful in hands and is designed to withstand harsh conditions.

The “L” ring is enough to convince some to buy the lens, but even as you investigate deeply, you will find out how excellent this macro lens for Canon EOS 5D Mark III is.


  • Superior color rendering
  • Excellent low-light performance
  • Creamy bokeh


  • Weight

Best Wide-Angle Lens For Landscape Photography

2. Sigma 24-35mm f/2.0

Sigma 24-35mm f/2.0 ART DG HSM has a large-diameter aspherical lens that allows a stunning level of brightness. The matter’s lens is the first full-frame f/2 zoomable lens designed for a zoom lens’s excellent performance and versatility.

The construction of the lens is solid. It feels heavy and bulky, yet it is nice to hold thanks to a solid finishing touch. The focus and zoom rings are designed exceptionally well.

I could compare them to Leica lenses with a butter-smooth but dialed inaccuracy; they move with comfort and stop at the very spot you intended. In terms of sharpness, the lens provides outstanding results.

I tested around with an aperture ranging from an f/2 to an f/2.8 and got impressive-looking images. The f/2 aperture is fantastic and provides beautiful bokeh. It’s sharp and fast.

Even more, the sharpness increased when I stopped down to an f/4, but the lens is quite sharp even at the maximum opening. Its low light capability handheld is second to none. It is on par with the finest prime lenses on the market.


This wide-angle lens works great when paired with Canon EOS 5D Mark III.

Colors are vibrant and natural, and sharpness is outstanding at all apertures, corner to the center. Although it covers a narrow focal length range, it is so versatile that it can replace two prime lenses.


  • Excellent performance
  • Great focusing and zoom rings
  • Beautiful bokeh


  • Narrow focal length range

Best All-Around Lens For Everyday Photography

3. Canon 24-70mm f/2.8

Canon EF 24-70mm f/2.8 L II USM has a constant f/2.8 maximum aperture with an f/22 at the minimum. Its ring-type is an ultrasonic AF motor with full-time manual focusing. The lens packs 82 mm filters, with the closest focusing distance of 0.38 m and a diagonal angle of view of 84° – 34°.

It is a perfect fit for new photographers looking to buy their first “big-boy” lens. No matter how well versed you are with focal lengths, you can utilize the lens to achieve the best results.

In terms of design, the lens is excellent, with the ability to take the beating and withstand harsh weather conditions. The 24-70 is mm plenty sharp, particularly at its wide end, where I use it a lot, and I value the versatility more than the increase in sharpness.


If one aims to do astrophotography, the calculus changes, but you can achieve concrete night sky photos if you use a tripod even with the matter’s lens.

The focus is super sharp, and the lens locks on to focus quickly with no noticeable motor noise. Paired with 5D Mark III silent shooting mode, you can take pictures of living things without disturbing them.

The general image quality is outstanding, with vivid colors and sharpness all across the frame. Although this all-in-one lens is heavy, it is worth every penny.


  • Weather resistant
  • Excellent image quality
  • Super sharp focusing


  • Heavy

Best Telephoto Lens For Wildlife Photography

4. Sigma 150-600mm f/5-6.3

Sigma 150-600mm f/5-6.3 Sports DG OS HSM comes with one SLD and four FLD elements, accompanied by a super multi-layer coating. The lens packs a hyper-sonic motor autofocus system and optical stabilization.

One of the first things I noticed about the lens is the lens hood, which is enormous. It is made of metal, and it is quite big, which means it slides over the front of the lens. The lens provides an excellent optic experience.

It delivers superior results at the maximum opening while stopping down to an f/8 improves image quality, and at f/11, the quality is also quite good.


Image stabilization does a beautiful job of achieving tack-sharp images. I was able to pull out beautiful images at 1/40 s at 600 mm using the Sigma dock.

The focusing system is another great selling point of this telephoto lens for Canon EOS 5D Mark III. It is fast, responsive, and sharp, although there is a slight defocusing at 600 mm.

One feature that I thought was useful was a focus limitation switch, which allowed me to specify the ranges at which the autofocus would work and when it would not. The simple fact helped ward off some of the hunt issues.

The great thing is setting micro-focus adjustments at the long and short end of the zooming range. The zoom ring is a little tight, but I would rather have it like this as being too slack.


  • Excellent optic experience
  • Image stabilization is great
  • Fast and responsive focusing


  • Zoom ring is a little tight

Best Macro Lens For Macro Photography

5. Canon 100mm f/2.8

Canon EF 100mm f/2.8 Macro USM comes with a closest focusing distance of one foot. It has a secondary diaphragm that blocks stray light at an f/2.8 for increased contrast.

It comes with an ultra-sonic monitor that provides fast autofocusing speed at all distances while still retaining a full-time manual option. It has a three-group floating system for an impressive close-up performance.

The macro lens in the matter is a dedicated macro lens, yet it can perform double and even triple duty as both portrait and fast medium telephoto lens.

Since I mostly tested it as a macro lens, I noticed how well the lens manages flare and ghosting thanks to a second diaphragm. It also has a fast focus when the limiter switch is set to keep it out of the macro range.

This macro lens is extremely sharp from edge to edge with minimal chromatic aberrations in terms of sharpness. Though there is slight vignetting, it is much less present compared to the competition.

A full-frame sensor produces 1:1reproduction, which means objects that you shoot at the closest focus distance will be the same size on the sensor as they appear in reality.

Last but not least:

The design feels sturdy even with plastic. It feels great in hands, and it looks like it is ready for harsh environments.


  • Perfect images
  • Weather-sealed
  • Excellent build quality


  • A bit on a heavy side
