When I first held the Canon EOS R100 in my hands, I was thrilled. Its compact size and user-friendly interface made it the perfect entry point into the world of mirrorless photography. I remember that initial excitement, the feeling of endless creative possibilities right at my fingertips. My first few shots with the kit lens were decent, capturing everyday moments and landscapes during a family trip to the northern areas. However, I soon realized that to truly bring my vision to life, I needed to explore the world of interchangeable lenses.
Like many beginners, I was initially overwhelmed by the sheer number of options available. What did all those numbers and letters even mean? Aperture? Focal length? Crop factor? It felt like learning a whole new language! But I was determined to learn and grow, and that’s where my lens journey with the Canon EOS R100 truly began.

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.
I recall using this lens extensively during a weekend getaway to Murree. It was lightweight and compact, ideal for carrying around as I explored the hilly terrain. 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. It taught me about composition and how different focal lengths can dramatically alter the perspective of a scene.
Why it’s great for the EOS R100:
- Compact and lightweight: Perfectly complements the R100’s portability.
- Versatile zoom range: Covers a wide variety of shooting scenarios.
- Image stabilization: Helps reduce camera shake for sharper images and smoother videos.

- Affordable: An excellent value for its performance.
Stepping Up the Sharpness and Speed: Canon RF 50mm f/1.8 STM

Oh, the nifty fifty! This lens is a game-changer for any photographer, regardless of their camera body. The Canon RF 50mm f/1.8 STM is incredibly sharp, offers a bright f/1.8 aperture, and is surprisingly affordable. This was one of the first prime lenses I purchased, and it opened up a whole new world of creative possibilities.
I remember the first time I used it for portrait photography. The way it blurred the background, creating that beautiful bokeh effect, was simply stunning. It made my subjects stand out and added a professional touch to my images. I even used it to capture some low-light shots at a local cultural event, and the f/1.8 aperture allowed me to capture bright and clear images without having to crank up the ISO too much. This lens truly taught me the importance of aperture and how it affects depth of field and low-light performance.
Why it’s a fantastic addition to your R100 kit:
- Exceptional sharpness: Delivers incredibly detailed images.
- Wide f/1.8 aperture: Allows for beautiful background blur (bokeh) and excellent low-light performance.
- Compact and lightweight: Maintains the R100’s portability.
- Fast and quiet STM autofocus: Ideal for both stills and video.
- Extremely affordable: Offers incredible value for its performance.
Zooming Further: Canon RF-S 55–210mm f/5–7.1 IS STM

As my interest in photography grew, I found myself wanting to capture subjects that were further away. This is where the Canon RF-S 55–210mm f/5–7.1 IS STM came into the picture. This telephoto zoom lens provides a significant reach, allowing you to photograph wildlife, sports, and distant landscapes.
I vividly recall using this lens during a cricket match. Being able to zoom in on the players’ expressions and the action on the field was a fantastic experience. While it might not have the widest aperture, the image stabilization helped me capture sharp shots even at longer focal lengths. It also proved useful during a trip to a bird sanctuary, allowing me to photograph various bird species without disturbing them. This lens taught me about compression in photography and how telephoto lenses can bring distant subjects closer.
Why it’s a great telephoto option for the R100:
- Extended zoom range: Perfect for capturing distant subjects.
- Image stabilization: Helps to minimize camera shake at longer focal lengths.
- Compact and relatively lightweight for its reach: Doesn’t add too much bulk to your bag.
- STM autofocus: Provides smooth and quiet focusing.
- Affordable entry into telephoto photography.
Exploring the Wider World: Canon RF 16mm f/2.8 STM

For those breathtaking landscape shots or when you want to capture the grandeur of architecture, an ultra-wide-angle lens is a must-have. The Canon RF 16mm f/2.8 STM is a fantastic option for the EOS R100. It’s incredibly compact, lightweight, and offers a wide field of view, allowing you to fit more into your frame.
I recently took this lens on a trip to Lahore’s historical sites, and it was perfect for capturing the vastness of the Badshahi Mosque and the intricate details of the Lahore Fort. The wide perspective created a sense of immersion, making the viewer feel like they were right there with me. The f/2.8 aperture also allowed me to experiment with astrophotography, capturing the beauty of the night sky. This lens opened my eyes to the dramatic possibilities of wide-angle photography and how it can transform a scene.
Why it’s a compelling wide-angle choice for the R100:
- Ultra-wide 16mm focal length: Ideal for landscapes, architecture, and vlogging.
- Bright f/2.8 aperture: Good for low-light shooting and shallow depth of field for creative effects.
- Extremely compact and lightweight: Perfect for travel and all-day carry.

Looking Ahead: My Future Lens Aspirations
My lens journey with the Canon EOS R100 is far from over. I’m constantly researching and dreaming about my next acquisition. Perhaps a dedicated macro lens to explore the intricate details of the natural world, or maybe a higher-end zoom lens with a wider constant aperture for even greater versatility.
The beauty of the Canon EOS R system is its growing ecosystem of lenses, and the RF mount offers incredible potential for future innovations. The Canon EOS R100, despite its entry-level status, is a capable camera that can produce stunning results when paired with the right glass.
