Canon EF 70-300 mm f/4-5.6 L IS USM
1. Introduction
That’s why I was so surprised when I heard about a next Canon launch in that segment – that of the Canon EF 70-300 mm f/4.0-f/5.6 L IS USM. There are really a lot of lenses in the Canon line-up which would need refreshing (like, say, the elderly EF 100-400 mm f/4.5-5.6L IS USM which stabilization system is far from what a modern optical construction should have). Meanwhile the company just gives us a new device in a segment featuring already a lot of other lenses to choose from; a device which can be easily substituted by a set of equally priced and of the same quality – I think here of the EF 70-200 mm f/4.0L IS USM and a 1.4x converter.
It is not my role to weigh up pros and cons of such a solution, though. Somebody working for Canon took such a decision and no other; the lens was launched on the market and I, as a tester, should simply check whether the designers of new Canon optics performed well or badly.
