Wednesday September 21 2011
A couple of days ago, we released the measurements for the Canon EF 70-200mm
f/2.8L IS II USM. With its wide aperture, its image stabilizer and its fast
auto-focus, this telephoto zoom lens is definitely one of the favorite
equipments of sport photographers. It is also ready to face difficult
weather conditions with its solid and watertight build.
Let’s see how it behaves in term of image quality compared to its
predecessor.
Canon EF 70-200mm f/2.8L IS II USM vs its predecessor :
If we compare these 2 generations of L series telephoto lenses on a Canon 5D
Mark II, we can see the following:
These 2 lenses are very similar in term of transmission, distortion and
vignetting
The version II gives slightly less chromatic aberration
The Canon EF 70-200mm f/2.8L IS II USM offers slightly less resolution
with 51 lp/mm compared to the excellent 61 lp/mm of the Canon EF 70-200mm f/
2.8L IS USM
The slightly less good resolution result of the Canon EF 70-200mm f/2.8L
IS II USM comes from less homogenous behavior across the field.
To conclude, these 2 lenses are both excellent telephoto lenses, but the
overall scores come out slightly in favor of the previous version of the
Canon EF 70-200mm f/2.8L IS USM, especially for Travel and Sport photography
, which are the main use cases of these telephoto zoom lenses.
Please note that if we compare the same lenses on an APS-C camera, the
results are much closer thanks to the smaller sensor: for example, here is
the comparison on a Canon EOS 7D. So, be sure to always compare lenses in
combination with the body on which you will be using it. |
