Lens review
Canon EF 100-400 mm f/4.5-5.6 L IS USM
11. Summary
Pros:
- high build quality,
- splendid or very good image quality in the frame center at all focal lengths and apertures,
- very good frame edge performance,
- low chromatic aberration,
- negligible distortion,
- low coma,
- low astigmatism,
- low vignetting at all focal lengths,
- silent, quick and accurate autofocus,
- rich accessory kit included.
Cons:
- weak performance against bright light,
- image stabilization not efficient by today’s standards
If the Canon 100-400 mm USM IS was equipped with the second generation stabilization system, allowing to work with 4 EV efficiency, and a bit better coatings we would pronounce it to be an ideal lens – for many applications even unique. I think the rumours about its withdrawal from the market and launching its successor are very real. We would have a move similar to the case of an L 70-200 f/4.0 lens, where Canon added IS to the old model and very good optical properties transformed into outstanding optical properties. Here the changes can be even smaller – a slight optics and stabilization improvement will give you a market hit for sure. Of course as long as Canon don’t go over the top with the price…
