Canon Canon RF 75-300mm f/4-5.6 Lens, Black Review

So you're looking for a budget telephoto lens for your Canon RF camera? The Canon RF 75-300mm f/4-5.6 is probably on your radar. It promises a lot of reach without a lot of weight, and at a price that won't break the bank. This lens is designed for photographers who want to get closer to the action, whether that's wildlife, sports, or just compressing scenes while traveling. It's a simple, no-frills zoom lens that covers a useful range. If you're wondering if this is a good starter telephoto lens, the short answer is: it's complicated. It gets you the focal length, but you have to know what you're giving up.

Let's talk numbers. The autofocus lands in the 48th percentile, which means it's just about average. It's not slow, but it's not the lightning-fast system you might hope for with fast-moving subjects. In good light, it's fine. In lower light, you might find it hunting a bit. The optical performance is in the 32nd percentile. That translates to decent sharpness in the center of the frame, especially when stopped down a bit, but the corners can get soft, particularly at the long end. There's no image stabilization, so you'll need a steady hand or a fast shutter speed to avoid blurry shots at 300mm.

This lens sits in the $210 to $239 range, which makes it one of the cheapest native RF telephoto zooms you can buy. That's the main draw. You're paying for the focal length and the Canon badge, not for exceptional optics or features. For the same money, you could look at used EF-mount lenses with an adapter, which might offer better image quality or a constant aperture. But if you want a brand new, native RF lens that's super light and gets you to 300mm, this is pretty much your only budget option.

It's tricky to compare this directly to the listed competitors like the Viltrox 35mm or Meike 55mm, as those are prime lenses for different camera mounts (Z-mount, E-mount) and serve completely different purposes. A more relevant comparison would be against other budget telephoto zooms. For Canon shooters, the older EF 75-300mm lenses are optically similar and often cheaper used, but you need an adapter. For other systems, lenses like the Nikon Z 50-250mm or Sony E 55-210mm offer similar reach with potentially better performance in their respective ecosystems. The key trade-off with the RF 75-300mm is that you're choosing extreme affordability and portability over optical performance and build quality.

Should you buy this? Only if your top priorities are low cost, light weight, and getting to 300mm on an RF camera, and you're willing to accept significant compromises everywhere else. It's a lens for very casual use, like occasional travel or zoo trips in bright sunlight. If you're serious about wildlife or sports, the slow aperture and mediocre autofocus will hold you back. For most people, I'd recommend saving up for something like the RF 100-400mm, which is a bit more expensive but a much better lens overall. This one feels like a stopgap solution.
