Summary: Canon's EF 75-300mm f/4-5.6 III...
Review: Canon EF Lenses Have A Built In AF Motor..Compared To Camera Body-Based AF Motors, Lens-Based Motors Have Driving Energy With Lower Transmission Loss...The AF Operation Is Therefore Quick, Quiet, And Highly Precise...All EF Lenses Also Have EMD (Electromagnetic Diaphragm) To Control The Aperture Electronically...The Aperture Can Be Set Either With An Electronic Dial Or With The Electronic Pulse Signal Sent According To The Exposure Reading...The Aperture Control Is Therefore Precise And Umnatched...To Go With Canon's Reputation, They Introduce A Lens That Is Truely Immaculate...Its Telephoto Zoom From 75mm-300mm Is A Great Addition To A Current Setup With A 28-80mm Lens And Is Ideal For Shooting Sports, Wildlife, Or Portraits...It Can Compress An Image To Give Dramatic Effects...The Optics And Construction Are Compact And Lightweight (Compared To My Nikon FM Setup) And The 4x Zoom Is Great...A Very Steady Shot Even At Maximum Zoom...The Apature Stops Are Adaquate, Being f4-f5.6, But Could Be Wider...All In All An Awesome Lens For The Money...Another Canon Hit... *Specs Taken From Canon's Catalogue...

Summary: Makes every photo look like a prizewinner
Review: I bought this lens about six months after replacing my 20 year old SLR with the Canon Rebel G. I didn't think photography could get any better. It did. The first day I used this lens, I was shooting photos of a biplane plummeting at an airshow. Having been used to my older equipment, I thought, "No way can I hold 300mm still enough, but what the heck, film is cheap." I was wrong. That photo was crystal clear, and instead of a tiny blur in the midst of sky, I have a very clear image of the plane filling the frame. The lens has been responsible for getting me up close in many places since, most recently capturing Al Gore and his entourage on the pilot house of the riverboat that travelled the Mississippi the day after the convention. If you are looking for a versatile lens that gives great results under many conditions, this is it. It really is hard to take a bad photo when using it.

Summary: Another Great Canon Lens
Review: I bought this lens for my Rebel 2000 camera and have been very pleased with the results. I never use autofocus, but the AF feature when I played with it was very fast and accurate. I got the best pictures by using an all-around 800 Max film with this lens.

Summary: low-class lens
Review: I have Canon's 75-300mm 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...

Summary: First Time Zoom lens
Review: I'd just got into SLR photography and the first few months with the 35-90 lens that came with the Canon Rebel 2000 were outstanding. I never realised there was SO much difference between a point-and-shoot and an SLR. After reading p on some of the books about photography, I reaslied an important point was getting the right framing and getting close to the subject. So I set out to look for a cost effective zoom lens that would give me that flexibility. I tried the cheeper rip off lens in the loal camera store and found their mechanisms stiff and slow focussing. I stuck my neck out for a canon make lens, and this one jumped out at me. It's perfect, the shot are crystal clear, the zoom is smooth and the autofocus is just as good as with the smaller lens. How do they make these lenses so cheap when competing lenses are more that twice the price? highly recommended for a novice like myself whodoesn't want to sped too much for telephoto zoom capability. I'm now looking for a canon 2x teleconverter to add to my range.

Summary: Great Lens!
Review: I'm using this lens with a Canon EOS Elan IIE camera, and have been thrilled with the results. My pictures are all clear, and look like I was up close! It is very easy to use, and is the lens that "lives" on my camera.
