The next item reviewed is the Canon 24-105 4.0L. This is obviously a mid range lens. It is my "On the camera" lens. This lens being a L series is incredibly sharp and well built. Interestingly there is nothing really special about this lens. It isn't very wide or very long. Its f/4 aperture, while constant is not that fast. If I were to pick out a defining feature the closest thing I would say is its all round functionality.
This 24-105 has weather sealing which is good for me! And 3 stops of IS. I like IS but only as a extra feature, something as a safety net to catch important shots.
I briefly considered the 24-70 2.8L but its limited zoom was a turn off for me in regard to nature photography. Also no IS :( In retrospect I could have made it work while enjoying the f/2.8...
I think the perfect solution to this dilemma would have been a 24-105 f/2.8 L IS USM. But unfortunately that for the moment is not happening.
As it is the only time I need a wide open aperture is dark places... And that is what a speedlite is for.
In conclusion I use this lens as an every day shooter, wildlife, landscape, portraiture, occasions, and weddings. This is a great lens.
