This is my personal love letter to Canon's engineering

:
I love to read Roger Cicala's blog, in particular before making a new investment. Over many years it does tell one story which IMO is more important than any lab tests: on the prosumer/pro level, Canon delivers exceptional quality. As a birder/wildlife photographers (amateur), my wife and I really mistreat our gear, we use it in heavy rain in the mountains, in sand & saltwater spray on winter shores etc., and I always experienced: my Canon simply works. Once my then already old and therefore a bit misused 7D swallowed sand in its thumb wheel, it crunched for a few weeks a bit and then the sand was milled out, but the camera never gave up to shoot. And my old battered EF 500mm crashed on rocks, was crusted with salt, banged against trees, but it still works flawlessly. Shooting side by side with comparable cameras and lenses, my wife's Nikon gear, unfortunately, proved many times to be much less reliable, we had a lot of repair so far.
This is the main reason why I still use Canon, despite the fact, that they lost some of their technical leadership on the camera side within the past ten years.
