Canon 75mm-300mm 4-5.6 vs Sigma 18-300mm Lenses

If you are looking for a versatile lens that can cover a wide range of focal lengths, you might be interested in comparing the Canon 75-300mm Zoom Lens to the Sigma 18-300mm Macro Zoom lens for Canon. These are two popular telephoto zoom lenses that can be used for various types of photography, such as wildlife, sports, portraits, and landscapes. However, they also have some significant differences that you should consider before making a purchase. Here is a brief overview of their main features and performance.

The Canon Offering

The Canon 75-300mm Lens is a budget-friendly option that offers a 4x zoom range from 75mm to 300mm. This is equivalent to 120-480mm on an APS-C format camera, which gives you a lot of reach for distant subjects. The lens has a maximum aperture of f/4-5.6, which means it is not very bright and may struggle in low-light situations. The lens also lacks image stabilization, which can make it hard to get sharp images at longer focal lengths without a tripod.

Canon’s offering uses a DC motor for autofocus, which is relatively fast and quiet, but not as smooth or accurate as a USM motor. The lens has a minimum focusing distance of 1.5m and a maximum magnification ratio of 0.25x, which means it can also be used for some close-up shots .

Who is Sigma? The best (biased) third party

The Sigma 18-300mm Lens is a more expensive option that offers a 16.7x zoom range from 18mm to 300mm. This is equivalent to 28.8-480mm on an APS-C format camera, which gives you both wide-angle and telephoto perspectives in one lens. The lens has a maximum aperture of f/3.5-6.3, which is slightly brighter than the Canon lens at the wide end, but similar at the telephoto end.

It has optical image stabilization, which can help you get sharper images at slower shutter speeds or longer focal lengths. The lens uses a HSM motor for autofocus, which is fast, quiet, and accurate . The lens has a minimum focusing distance of 0.39m and a maximum magnification ratio of 0.33x, which means it can also be used for macro photography .

Both lenses have some advantages and disadvantages that you should weigh according to your needs and preferences. The Canon lens is cheaper, lighter, and more compact than the Sigma lens, but it has less zoom range, no image stabilization, and lower image quality .

The Sigma lens is more expensive, heavier, and bulkier than the Canon lens. Though it has more zoom range, image stabilization, and better image quality . Both lenses suffer from some optical flaws such as distortion, chromatic aberration, vignetting, and softness at the edges. That can be corrected in post-processing or by stopping down the aperture.

Zoom zoom conclusions

The Canon 75-300mm Lens and the Sigma 18-300mm Lens are two telephoto zoom lenses that can offer you different levels of versatility and performance for your Canon camera. Depending on your budget, style, and expectations, you may prefer one over the other. However, if you want the best image quality possible from a telephoto zoom lens. You may want to look at other options that have faster apertures, better optics, and higher prices.

My Workhorse

However, the Sigma 18-300mm is my workhorse.

What makes this lens even more impressive is its macro capability. The Sigma 18-300mm Macro lens has a maximum magnification ratio of 1:3. Which means you can get close to your subjects and reveal stunning details in Macro. The lens also features a Super Multi-Layer Coating that reduces flare and ghosting.

A Hyper Sonic Motor that ensures fast and quiet autofocus, and an Optical Stabilizer that helps you avoid camera shake.

What can all of those fun features do? Get you to take amazing zoom and landscape shots… and also, macro work that is incredibly detailed.

The Sigma 18-300mm Macro lens is a great option for photographers who want to travel light. Though the lens is heavy, it’s one lens that does a lot.

It is compatible with Sigma’s USB Dock and Mount Converter, so you can customize and update your lens as needed. It also comes with a lens hood and a padded case for extra protection. If you want to learn more about this lens, visit the Sigma website or watch some reviews on YouTube.
