Canon EF 300mm f/4L IS USM Telephoto Lens for Canon SLR Cameras – Review:
CANON 300 F4L OFFERS AMAZING PERFORMANCE!
I got this lens for shooting architecture from a distance–an unsual application. I’ve also found myself using it to shoot kids soccer games. It’s super sharp and very fast focusing. I haven’t done formal tests at all apertures, but images appear vivid and contrasty at a range of settings. Online reviews rank this lens very highly and my own experience supports those findings.
The Image Stabilization seems to work very well, although be sure to turn it off if you’re using a tripod–I’ve found that it can reduce image quality if you forget to turn it off in that application.
For shots where you’ll be standing around a lot with the lens to your eye, ready for a shot, it gets kind of heavy to carry. If you’re shooting sports, you might want to consider a monopod. For other applications, its weight is low enough not to be too big of a problem.
It comes with a canvas-like case that includes a loop you can use to attach it to your belt. I’ve found this works pretty well out in the field, particularly when combined with a photo-vest. The case also can be carried with a neck strap, but this gets in the way of your camera strap and is also thin, so it kind of cuts into your shoulder.
As I write this, the Amazon site has a link for 58mm filters for this lens. It takes 77mm filters.
