Short answer: Which lenses are best for the Canon EOS R100?

The guide covers the kit RF-S 18-45mm, the RF 50mm f/1.8 STM, the RF-S 55-210mm and the RF 16mm f/2.8 STM. It starts with the kit lens and then suggests sharper, faster upgrades.

Its compact size and user-friendly interface made it the perfect entry point into the world of mirrorless photography.

What did all those numbers and letters even mean? Aperture? Focal length? Crop factor? It felt like learning a whole new language!

The Versatile Kit Lens: Canon RF-S 18–45mm f/4.5–6.3 IS STM

Let’s start with the lens that likely came bundled with your EOS R100. The Canon RF-S 18–45mm f/4.5–6.3 IS STM is a surprisingly capable little workhorse. Its zoom range covers everything from wide-angle shots to short telephoto, making it perfect for everyday snapshots, landscapes, and even some casual portraits.

The image stabilization (IS) was a lifesaver for capturing sharp photos and videos, especially in lower light conditions. While it might not have the widest aperture for creamy bokeh or the longest reach for wildlife, it’s an excellent starting point and a fantastic lens to learn the fundamentals of photography with.
