On this review photographer Christopher Frost looks at the Canon EF 70-300mm f/4-5.6L IS USM lens to see if it can deliver.
The Canon EF 70-300mm f/4-5.6L IS USM was announced in mid 2010 and is one of the more expensive versions of this lenses in its category (even more expensive than the already pretty expensive Sony FE 70-300mm f/4.5-5.6 G OSS Lens – although to be fair it is a bit faster on the wider side).
The lens is very well built but it does extend when zoomed and is quite heavy (around 1kg). It does cover both APS-C and Full Frame and has a very good image stabilization system and is weather sealed. The zoom ring is the further away (the focus ring is closer to the camera) which is kind of strange and not that convenient design.
The lens is super sharp on Full Frame with very good results all across the frame on almost all apertures (below f/11 at least) this is also true on APS-C – this is impressive but is kind of expected given the price.
