Rank #3 in Best 70-200mm Lenses 2026: 9 Ranked, and Five Aperture Fields That Don't Add Up
Canon EF 70-200mm f/2.8L IS III USM
Price and rating as shown on Amazon when we collected them. Both change.
The Canon EF 70-200mm f/2.8L IS III USM is the third entry in our guide to 70-200mm lenses. It is an EF-mount telephoto zoom for Canon EOS DSLRs, listed at £1,694.99 with 4.6 out of 5 from 205 ratings. Canon positions it for event, sport and wildlife work, and the listing's own bullets point to a 3.5-stop image stabiliser, fluorite and UD optics, and a ring-type USM motor.
The spec table is where this fiche gets interesting, and not in a good way. It gives "Maximum Aperture: 32 f" and "Minimum Aperture: 2.8 f" — the two fields are the wrong way round, because f/2.8 is the widest opening the lens has and f/32 the narrowest, exactly as the product name and the first bullet ("f/2.8 maximum aperture") say. Other fields are loose in the same style: a zoom with a "Fixed Focal Length" of 70 millimetres, a "Screen Size" of 19.9 centimetres, a "Lens Colour" of Black against a "Colour" of White, and a compatible-camera entry written in Italian. Nothing on this page was measured by us — every figure comes from the Amazon listing, including the ones that disagree with each other.

Questions people ask
What is the maximum aperture of the Canon EF 70-200mm f/2.8L IS III USM?
The listing's spec table says "Maximum Aperture: 32 f" and "Minimum Aperture: 2.8 f". That is the reverse of the product name and of the first bullet, which describes an f/2.8 maximum aperture, so read the two fields as swapped.
Is the Canon EF 70-200mm f/2.8L IS III USM weather-sealed?
The bullets say protective seals guard against dust and moisture, and that the front and rear elements carry a fluorine coating that is easy to clean.
What filter size does the Canon EF 70-200mm f/2.8L IS III USM take?
The listing gives a photo filter size of 77 millimetres.
Which cameras does the Canon EF 70-200mm f/2.8L IS III USM fit?
The compatibility bullet names Canon EOS DSLR cameras with EF/EF-S mount. The separate compatible-camera-models field is written in Italian: "Tutte le fotocamere Canon con attacco EF".
How much light does the f/2.8 aperture let in?
The listing states that a fast f/2.8 aperture lets in twice as much light as an f/4 lens, and that the 3.5-stop image stabiliser guards against camera shake.
How is the Canon EF 70-200mm f/2.8L IS III USM rated by buyers?
It holds 4.6 out of 5 across 205 ratings, with 85 of those ratings at five stars and 6 at one star.
