If you're on a 1.3x or 1.6x crop body (the XTi for example) will give you 112-480mm, which is nice for the extra distance, however, if your wanting to be up with your family and friends and get full body shots you have to be standing quite far away.

Excellent image quality while not an L series lens with a wide aperture it still rocks in cloudy/low light conditions; I've taken 2,000+ images with this lens and it has not let me down

Louder auto focus than other USM lenses, not by a lot though; Autofocus hunts in lowlight at 300mm

I've used the product to photograph landscape and some wildlife. The Canon 70-300L works very well on both my Canon 5D2 and my Canon 50D. the only problem is that you can't zoom with the lens shade reversed.

Quaility product; Fast focusing

Too expensive; Heavy

A bit too expensive than its tamron counterpart but they differ in quality. Amazing picture quality is given by this lens. Perfect zoom and sharp and fast focus. A nice lens to buy.

This lens is highly versatile and rarely requires me to change lenses. It is a genuine Canon lens with the packaging you would expect to receive if buying the same product in Australia.

I haven't had this lens long but have found it to be excellent. It is quite expensive so I gave it 4 stars for value. This is not a reflection of the quality but just the price. I did receive the money back from Canon quite fast this time in contrast to my previous experience.

This is an excellent mid level zoom lens for the enthusiast or cash strapped semi-professional who needs a decent zoom lens. I bought mine through Amazon Warehouse Deals in Like New condition for about half price, so I did really well price wise.

This lens has an auto and manual setting for focus adjustments and the adjustments give a good blur effect to the image, very nice lens indeed, very good to have this.

I was looking for a lens that could take shots of wildlife from a distance. This lens certainly fits the bill and the IS helps in low light. I was also looking at the 100-400mm lens but the negative comments about its barrel focusing system pushed me towards this one.

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Rugged; Strong Construction

Heavy; Poor in Low Light

I purchased this zoom lens from ZeeMo Digital at a very great price and it lived up to the expectations I envisioned.It was shipped out quickly and was also packaged nicely.

A bit too expensive than its tamron counterpart but they differ in quality. Amazing picture quality is given by this lens. Perfect zoom and sharp and fast focus. A nice lens to buy.
