This compact and lightweight EF 75-300mm telephoto zoom lens is ideal for shooting sports, portraits, and wildlife. The lens is distinguished by a newly developed micro ultra-sonic monitor (USM) that makes autofocusing quicker and quieter, along with an improved zoom mechanism that includes a silver ring on the front for a luxurious touch. The micro USM makes this version of the lens particularly suitable for applications that require a fast autofocus, such as sporting events or wildlife shoots. Best of all, the USM version shares many of the same features that makes the non-USM lens so popular, such as a compact size, a close focusing range, and accessory compatibility. As with all Canon lenses, this unit carries a one-year warranty.

Developed to succeed the EF75-300mm f/4-5.6 II this compact, lightweight high- magnification telephoto zoom lens covers medium telephoto 75 mm to super telephoto 300mm. Like the EF75-300mm f/4-5.6 III USM, it has a metal ring at the front of the zoom ring to give it an upscale image. It uses a DC motor as AF drive actuator. The optical system and controls are the same as those of the EF75-300mm f/4-5.6 III USM. For environmental protection, only lead-free glass lens elements are used.

I am a novice and beginning to enjoy picture taking. This lens is a capable lens. It can capture some great images but in low light it requires a tripod since my hands are kind of shaky. For the money is is a great tool to have in your bag. If I were to do it over again I would have saved my money and gotten a lens that had image stabilization and maybe a faster aperture. Also this lens does allow me to capture images from a further distance. That way I don't have to get right into my 8ft boa's face to get some good close ups.

For a very reasonable price you get pretty good quality. not bad for a novice like me.I suppose if I was a pro this would not be good enough but the lens is as good as this user is and I have enjoyed the pictures I have taken with it.

I was between this lens and the IS (image stabilization) model. For the price I tried this model, as I have gone this far, about 40 years, with out IS. I am very pleased with the overall quality. In full sun I have hand held it at about 250mm, with great results. Otherwise I'll use a tripod. No big deal. I use the lens on a Rebel XTi and find the balance to be very pleasing. Shooting wild life in lower light conditions, it would be nice to have another f stop, but now you are talking a lot more money.

Great lens. Very smooth manual focus and zoom, and autofcous is seemless. Well worth the money.

If you are looking for a lens with this sort of focal length, it is going to be your cheapest option. It focuses slow. Really really slow. I have the 5D with the 24-105L, and it is almost painful to switch between the two. If you are trying to shoot a kids soccer game in broad daylight this will suit you fine. If you are taking pictures of your dog on a Sunday afternoon. This is not a focal length I use a lot, so it suits me fine. If you are serious about sport or wild life photography, you aren't going to buy this anyway. I would suggest saving your pennies and buying the 70-200 f/4L for just over $500. Kinda wish I had done that, but I had already dropped enough on the 5D.
