Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens for Canon SLR
By : Sergiy Beketov "apollinaris"

I have Canon's 75-300mm telephoto zoom lens for almost a year and have examined it inside out. Unfortunately, I cannot admit that it's a good lens.

First of all, it doesn't have USM (Ultra Sonic Motor) and though having built-in AF motor, it is anyway VERY slow. And since telephoto lenses in general are for capturing high-speed events (like sport, running animals etc), its low-speed focusing makes it no good.

Secondly, its light-factor is quite low (4.0 for 75mm and only 5.6 for 300mm) what forces you to use either high-speed film (not lower than ISO400) or to shoot in the bright light (what's not possible everytime you shoot).

And the last, but not less important thing. I'm not good in mechanics, but what I know for sure is that Canon's 75-300mm lens produce unsharp pictures. No matter if you use a tripod or not, the pictures still are very unsharp which is very bad for images, being zoomed by 300mm.

Anyway, I'd recommend you to buy the lens of the same focal distance but in another configuration: Canon EF 75-300 F/4.5-5.6 IS USM. Although it's a bit expensive and as you see, the light factor is a bit lower, too, it has an USM and IS (Image Stabilizer) what makes focusing drastically super fast and the pictures become more sharper with the help of IS. This lens deserves a high attention. But not this one...
