Canon 24-105/4L IS USM

Until recently I had resisted the temptation to upgrade my perfectly fine Canon 28-135/3.5-5.6IS USM to the new 24-105/4L. In fact, there was no temptation as I was perfectly happy with the results my older, non-L lens delivered. Even in my warped logic, I couldn’t think of any reason to spend $1050 for a lens when my 10 year old, $410 lens turned out such great photos as below.


However, as the saying goes, “I can resist anything except temptation!” When a known, reliable member of posted his 24-105 for sale for $850, I couldn’t resist. I immediately sent the money via PayPal and received the lens the following week.

I haven’t really put it through its paces yet so I can’t comment too much on how it stacks up against the venerable 28-135 but I can tell you it’s a well built lens that’s heavier than the 28-135 (1.48 lbs vs 1.21 lbs). That 4.32 oz may not sound like much but it definitely gives the 24-105 a substantial feel and heft. The big deal is that the 24-105 is a constant aperture f/4 while the 28-135 is f/3.5-f/4 up to about 45mm and falls off to f/5.6 at 85mm. That means you lose a half stop of light after 45mm and a full stop after 85mm. Again, this may not sound like much but, just think, a stop is twice as much light (or half as much, depending on the direction). So, in low light conditions, an f/4 lens can capture images in half the light as an f/5.6 lens. This can be the difference between getting the shot or not.

Since I don’t have any comparable images made with the 24-105, I’ll work on that next week while attending the 1st Annual California Photo Festival in Los Osos, CA. I will have plenty of opportunities to photograph landscape, flora, fauna, people and anything else that wanders into my viewfinder.
