Best camera for the canon ef 28 135mm f 3 5 5 6 is usm?
The Canon EF 28-135mm is a good walkaround zoom, and I'd pair it with a full-frame body so it frames the way it's marked. My everyday pick is the Canon EOS 6D Mark II. On full frame you get the full 28-135mm range, and the lens is stabilised, which helps when you're handholding.
If you want a smaller, more affordable body, the Canon EOS 80D is a solid APS-C choice. On it the lens works out to roughly 45-216mm, which gives you more reach for wildlife or sport but loses some wide-angle coverage. If you want more full-frame power, the Canon EOS 5D Mark IV is the one I'd look at.
Not sure which framing suits you? The focal length guide explains what each range is good for.
