Pros
- Offers a 75-300mm (120-480mm equivalent on APS-C) telephoto zoom range for reaching distant subjects.
- Weighs 1.12 pounds, making it portable for a telephoto zoom lens.
- Priced in the $150-$299 range, making it an accessible telephoto option.
- Can achieve professional-looking background blur and compression at longer focal lengths.
Cons
- Lacks optical image stabilization, making sharp handheld shots difficult, especially at 300mm.
- Autofocus motor is slow and noisy, described as an old DC motor from 1999.
- Images are soft, particularly at 300mm and wide open at f/5.6, requiring stopping down to f/8 or f/11 for sharpness.
- Exhibits significant purple fringing at longer focal lengths (200-300mm).
- Focus ring and front element rotate during autofocus, hindering handling.
Dimension Scores
Images are notably soft at 300mm and wide open, and it exhibits significant purple fringing at longer focal lengths.
The lens uses an old, basic electric DC autofocus motor from 1999, resulting in sluggish and noisy performance.
The noisy autofocus motor makes it practically unusable for video recording with an on-camera microphone.
At 1.12 pounds, it's relatively lightweight for a telephoto zoom lens with a 75-300mm range.
Best For
- Budget-conscious photographers needing extreme telephoto reach for occasional, well-lit shots.
- Users with Canon R-series cameras featuring In-Body Image Stabilization (IBIS) to compensate for the lack of lens IS.
- Experimenting with telephoto compression and background blur without a significant investment.
Not Recommended For
- Anyone needing fast, quiet, or reliable autofocus for sports, wildlife, or video recording.
- Photographers prioritizing sharp images across the zoom range, especially at 300mm.
- Beginners without IBIS, as getting sharp handheld shots at 300mm will be a struggle.
Watch Out For
- No image stabilization means you'll need shutter speeds of 1/500s or faster at 300mm for sharp handheld photos, even with good technique.
- The autofocus motor is loud enough to make it unusable for video with an on-camera microphone.
- Image quality at 300mm and f/5.6 is notably soft, requiring you to stop down to f/8 or f/11 for better sharpness, which demands more light.
- This lens is a re-housed version of a 1999 EF lens, meaning it uses outdated optics and a slow AF motor.

What Buyers Say
Many users express disappointment, noting that this lens is essentially a re-housed version of a very old and poorly performing EF lens, not a modern RF design. The most frequently cited issues are the lack of image stabilization, making it hard to get sharp shots, and a slow, noisy autofocus motor that's particularly problematic for video. While its low price is appealing, the compromises in image quality and performance are significant, especially at the longer end of the zoom.
“Dude, I bought this 'cause it was cheap and I needed a long lens for my R50, but holy cow, it's so soft at 300mm and the AF sounds like a dying robot. My pictures are blurry unless the sun is blasting and I'm shooting at 1/1000th. Should've just saved up for something better.”
Common Praise
- The 75-300mm focal length provides significant reach for distant subjects.
- It's one of the cheapest telephoto options available for Canon RF mount.
- Lightweight at 1.12 pounds, making it easy to carry.
- Can produce background blur and compression for a 'professional look'.
Common Complaints
- Images are soft, especially at 300mm and wide open, requiring smaller apertures for sharpness.
- Autofocus is slow, noisy, and uses an outdated motor.
- Lack of image stabilization makes handheld shooting at telephoto lengths very difficult to keep sharp.
- Exhibits noticeable purple fringing at longer focal lengths.
- The focus ring and front element rotate during autofocus, which is annoying.
Ownership Tips
- You'll quickly learn the importance of fast shutter speeds or a tripod to compensate for the lack of image stabilization at 300mm.
- The noisy autofocus motor becomes very apparent when trying to record any video, making it a non-starter for vlogging or quiet environments.
- You'll find yourself consistently stopping down the aperture to f/8 or f/11 to get acceptable sharpness, especially at the long end, which limits its use in lower light.
- The rotating front element during autofocus is annoying if you use polarizing filters or other screw-on accessories.
Frequently Asked Questions
Does this lens have image stabilization?
No, this lens does not have built-in optical image stabilization. You will need a camera with In-Body Image Stabilization (IBIS) or very fast shutter speeds to get sharp handheld photos, especially at longer focal lengths.
Is this lens good for video?
No, it's not recommended for video. The autofocus motor is very noisy, making it unsuitable for recording video with an on-camera microphone.
Is this a new lens design for Canon RF mount?
No, this lens is widely reported to be a re-housed version of the old Canon EF 75-300mm f/4-5.6 III lens, using the same optical formula and an old DC autofocus motor from 1999.
How is the image sharpness?
Image sharpness is a common complaint. It's described as soft, particularly at 300mm and wide open at f/5.6. Stopping down the aperture to f/8 or f/11 can improve sharpness.
Will this lens work well on an APS-C camera like the R50?
While it provides an equivalent focal length of 120-480mm on APS-C, its flaws, such as softness and lack of stabilization, are often magnified on crop sensors, making it even more challenging to use.
Buying Guide
When looking at telephoto lenses like this, you need to think about how far away your subjects will be and how much light you'll have. A long focal length, like 300mm, lets you zoom in a lot, but it also magnifies camera shake, making image stabilization crucial. Also, the maximum aperture (like f/5.6) tells you how much light the lens can gather; a smaller number means more light and better low-light performance.
75-300mm focal length
This range lets you zoom from a moderately tight shot (75mm) to pulling distant subjects much closer (300mm). Think of it like binoculars for your camera, bringing far-off birds or athletes into view.
f/4-5.6 maximum aperture
This indicates how wide the lens opening can get. f/4 is wider than f/5.6, meaning it lets in more light. Since this lens gets 'slower' (f/5.6) at its longest zoom, you'll need more light or higher ISO settings to get a bright, sharp image at 300mm.
No Image Stabilization (IS)
IS helps reduce blur from shaky hands, especially at longer focal lengths. Without it, you'll need to use much faster shutter speeds or a tripod to keep your photos sharp, which can be tough in dim lighting or with moving subjects.
Alternatives
If this lens doesn't cut it, look for a telephoto zoom with built-in optical image stabilization (IS), a constant or wider maximum aperture (e.g., f/4 throughout the zoom), and a modern, quiet autofocus motor.
