Best Starter Lens for Canon EOS R100
The Canon EOS R100 is a fantastic entry point into the mirrorless world, but its true potential is often masked by the basic kit lens it ships with. If you’ve found your indoor photos look grainy or your backgrounds aren’t as blurry as you’d like, the problem isn’t the camera—it’s the glass. I’ve tested dozens of RF lenses, and for the R100, I believe the RF-S 18-150mm is the absolute gold standard for beginners seeking versatility.

Best Starter Lens for Canon EOS R100: Detailed Reviews
Canon RF-S 18-150mm f/3.5-6.3 IS STM View on Amazon View on B&H
If you only ever buy one lens for your R100, make it the RF-S 18-150mm. I find this lens exceptional because it covers everything from wide-angle landscapes to distant wildlife without you ever having to swap lenses. On the R100’s APS-C sensor, the effective focal length is roughly 29-240mm, which is incredible for a lens this light. It features 4.5 stops of optical Image Stabilization, which is vital since the R100 lacks in-body stabilization. The STM motor is whisper-quiet, making it great for the occasional video clip too. While the aperture isn’t the widest, the sheer convenience and surprisingly sharp image quality outweigh the need for a faster lens in most daylight scenarios. It feels well-balanced on the small R100 body, unlike some of the heavier full-frame RF glass.

Canon RF 50mm f/1.8 STM View on Amazon View on B&H
The “Nifty Fifty” is a rite of passage for every photographer, and it shines on the R100. Because of the 1.6x crop factor, this lens behaves like an 80mm portrait lens, which is the “sweet spot” for flattering headshots with creamy, blurred backgrounds. The f/1.8 aperture is a game-changer for R100 users struggling with indoor lighting; it lets in significantly more light than the kit zoom. I’ve used this lens for evening street photography and the results are punchy and sharp. Its only real drawback is the lack of built-in Image Stabilization, so you’ll need a steady hand or a faster shutter speed to avoid blur. However, for the price, the optical quality is simply unbeatable. It’s tiny, lightweight, and transforms your R100 from a “basic camera” into a professional-looking portrait machine.

Canon RF-S 18-45mm f/4.5-6.3 IS STM View on Amazon View on B&H
If you bought your R100 body-only and need a versatile lens on a strict budget, this is the default choice. It is incredibly compact—when retracted, it barely protrudes from the camera, making the R100 almost pocketable in a large jacket. The 18-45mm range covers the most common perspectives, from group shots to light portraits. While the f/4.5-6.3 aperture is admittedly “slow” (meaning it struggles in dark rooms), the built-in 4-stop Image Stabilization helps significantly for static subjects. You’ll notice it’s very light, which complements the R100’s featherweight build perfectly. It’s not the sharpest lens Canon makes, and the plastic mount feels a bit entry-level, but for outdoor family gatherings or travel vlogging, it gets the job done without breaking the bank or your back.

Canon RF 35mm f/1.8 Macro IS STM View on Amazon View on B&H
For those willing to spend a bit more, the RF 35mm f/1.8 is my personal favorite on the R100. It gives you a “normal” field of view (roughly 56mm equivalent), which mimics how the human eye sees the world. This makes it incredibly intuitive for beginners to compose shots. What sets this apart is the 1:2 macro feature—you can get remarkably close to flowers, wedding rings, or food details. Unlike the 50mm, this lens *does* include Image Stabilization, which is a massive help when shooting video or working in low light. The build quality is a step up, featuring a dedicated control ring that you can customize to change your ISO or exposure compensation. It’s sharp, fast, and offers a level of creative freedom that cheaper kit lenses simply cannot match.

Canon RF-S 10-18mm f/4.5-6.3 IS STM View on Amazon View on B&H
If you’re using your R100 for YouTube or TikTok, you’ll quickly realize that the standard 18mm kit lens isn’t wide enough to show your face and the background when holding the camera at arm’s length. The RF-S 10-18mm solves this perfectly. It provides an ultra-wide view that makes small rooms look huge and landscapes look epic. It’s incredibly light—almost like a toy—but the optical performance is genuinely impressive. The Image Stabilization is specifically tuned for video, helping to smooth out those walking-and-talking shots. Just be aware that because it’s so wide, you’ll get some distortion if you get too close to people’s faces. It’s a niche lens, but for creators and architecture lovers, it’s a vital addition to the R100 kit bag.

Frequently Asked Questions
Can I use full-frame RF lenses on the R100?
Yes, you can use any RF lens on the R100. However, full-frame lenses (those without the “S” in RF-S) are usually larger, heavier, and more expensive. While they offer great quality, they might feel unbalanced on the tiny R100 body. You will still experience the 1.6x crop factor regardless of whether the lens is designed for full-frame or APS-C sensors.
Does the R100 have image stabilization?
No, the Canon R100 does not have In-Body Image Stabilization (IBIS). This is why it is highly recommended to choose lenses that have “IS” in their name. Optical stabilization within the lens helps counteract your hand movements, which is crucial for sharp photos in dim light and for keeping your video footage from looking shaky.
Is the 50mm f/1.8 good for vlogging?
Generally, no. On the R100, the 50mm acts like an 80mm lens, which is quite zoomed in. If you hold the camera at arm’s length, only your nose and eyes might fit in the frame! For vlogging, you are much better off with the RF-S 10-18mm or even the 18-45mm at its widest setting of 18mm.
Do I need an adapter to use these lenses?
No adapter is needed for any of the lenses listed in this guide. They all use the native RF mount. You would only need an EF-to-EOS R adapter if you wanted to use older lenses from Canon’s DSLR era. Native RF and RF-S lenses are recommended for the best autofocus performance and weight savings.
Which lens is best for blurry backgrounds?
The Canon RF 50mm f/1.8 STM is the champion for blurry backgrounds (bokeh). The large f/1.8 aperture allows for a shallow depth of field, which separates your subject from the background beautifully. The RF 35mm f/1.8 is a close second, offering a similar effect but with a wider field of view.
Final Verdict
For the vast majority of Canon EOS R100 owners, the RF-S 18-150mm is the smartest investment; it eliminates the need to carry multiple lenses while traveling. If you’re a budding portrait artist or want to shoot in low-light restaurants, the RF 50mm f/1.8 is a mandatory second lens for your kit. Finally, if you’re a vlogger or landscape enthusiast, the RF-S 10-18mm will provide that wide perspective you’re currently missing.
