The Canon EOS R7 is a fast APS-C body built for action and wildlife, and it uses the RF mount with a growing set of RF-S crop lenses plus full-frame RF glass. The best choice depends on whether you want reach, a compact travel kit, or bright low-light primes.
We compared native RF-S zooms, long telephotos, and affordable primes, weighing sharpness, autofocus, and how each balances on this compact but capable camera.

Detailed Reviews and Top Picks
1. Canon RF 100-400mm f/5.6-8 IS USM
89/100
Best for Wildlife
Key spec: RF telephoto zoom, stabilized, full-frame RF.
On the R7 this lens gives a massive effective reach that is ideal for birds, wildlife, and sports, yet stays light enough to carry all day. Stabilization and sharpness are impressive for the price. The narrow variable aperture means it prefers daylight, so photographers shooting at dawn or dusk will need to raise ISO to keep shutter speeds up.
- Long reach for wildlife and sports
- Light and easy to handhold
- Effective image stabilization
Pros
- Huge effective reach on APS-C
- Very portable for a supertele
- Sharp for the price
Cons
- Slow variable aperture
- Best in good light
2. Canon RF-S 18-150mm f/3.5-6.3 IS STM
87/100
Best All-in-One
Key spec: RF-S superzoom, stabilized.
For travel and everyday use, this RF-S superzoom covers wide-angle to long telephoto in one compact package, making it the grab-and-go lens for the R7. Stabilization helps both stills and video. It has a slow variable aperture and softer extreme corners, so low-light and critical-sharpness shooters will want a prime or the pro zooms alongside it.
- Wide to telephoto in one lens
- Stabilized for handheld and video
- Compact for the range
Pros
- Enormous everyday flexibility
- Great travel and family lens
- Light and easy to carry
Cons
- Variable aperture is slow
- Corners soften at extremes
3. Sigma 18-50mm f/2.8 DC DN
85/100
Best Value Zoom
Key spec: RF-S standard zoom, constant f/2.8.
Sigma brought its compact f/2.8 zoom to Canon RF-S, and it is a superb value upgrade over a kit lens for the R7, with a bright aperture and real sharpness. It is a great everyday and low-light option. The lack of stabilization and short range mean it is best paired with a longer or stabilized lens for full coverage.
- Bright constant f/2.8
- Compact and sharp
- Great value
Pros
- Fast aperture in a small body
- Sharp everyday range
- Affordable
Cons
- No stabilization
- Short zoom range
4. Canon RF-S 10-18mm f/4.5-6.3 IS STM
82/100
Best Wide Angle
Key spec: RF-S ultra-wide zoom, stabilized.
This tiny ultra-wide is the go-to for landscapes, interiors, and vlogging on the R7, adding a genuinely wide view in a pocketable size. Stabilization helps handheld and video work. The slow aperture limits low-light use and there is some distortion, so it is a specialist companion rather than an all-day lens.
- Ultra-wide view for the crop sensor
- Very small and light
- Stabilized
Pros
- Great for landscapes and vlogging
- Extremely compact
- Affordable ultra-wide
Cons
- Slow variable aperture
- Some distortion wide open
5. Canon RF 50mm f/1.8 STM
80/100
Best Budget Prime
Key spec: RF standard prime, f/1.8.
On the R7 this 50mm acts like a short portrait lens and is the cheapest way to add real low-light ability and background blur. It is tiny and fun to carry. Autofocus is fine for portraits but slower than USM lenses for action, and the build is basic, so sports shooters should not rely on it for fast subjects.
- Bright aperture for low light
- Tiny and light
- Natural portrait-length view on APS-C
Pros
- Superb value
- Nice background blur
- Pocketable second lens
Cons
- STM focus is slower
- Basic build
6. Canon RF 85mm f/2 Macro IS STM
77/100
Best Portrait
Key spec: RF short telephoto prime, f/2, stabilized, half macro.
This 85mm becomes a longer portrait lens on the R7 and doubles as a half-macro, which makes it a creative two-in-one with helpful stabilization. Rendering is pleasing and the price is fair. The effective focal length is quite long on APS-C and autofocus can slow on low-contrast subjects, so it suits deliberate portraits more than fast candids.
- Portrait-length reach on APS-C
- Half life-size close focus
- Built-in stabilization
Pros
- Flexible portrait and macro lens
- Stabilization aids close-ups
- Reasonable price
Cons
- Focus can hunt in low contrast
- Long effective focal length on crop
