Canon EF 70-300mm f/4-5.6 IS USM Telephoto Zoom Lens

Canon Ef 70-300 f/4-5.6 IS USM

Strengths: Lightweight, IS, and sharp.

Weakness: A bit loud, and built quality is average.

I had been looking for a zoom telephoto lens for shooting wildlife. Thinking of getting a Canon EF 70-200 f/4L, but found this new lens from Canon. After doing some research, the sharpness of this lens seems to be comparable to the EF 70-200 f/4L, plus this lens has the extra 100mm zoom. Furthermore, the IS on this lens seems to be performing better than my EF 28-135. If you want a mid-level...

Light Weight, and the IS works

Strengths: Light Weight, 2 Modes of IS, Small Size, Sharp

Weakness: Slow (f/4-5.6), Slow focusing, Build Quality

This is not an L-Series lens. It doesn't have the feel. The focus speed is not fast. However, the lens is less than the price of an L lens with similar zoom range. The IS works very well. I got many successful hand held shots at 300mm with 1/40s shutter speed. I like the 2 modes of IS, it lets me shot bird in flight with ease.

A Great Lense

Strengths: Easy to use and understand

Weakness: None

Used it for the first time-easy to use and work. Took great photos of kids sports/action. Bought it becuase of price compared to a 2.8 lense. Used in low light and it did the job

Terrific IS Performance, OK Built and Sharp Image.

Strengths: IS, IS, still IS, and maybe the extra 100mm focal length, too.

Weakness: No FTM, No Lens Hood, No IF.

Just got this lens and tried it out for 2 days. Very surprised by the image quality this lens can produce. I can shoot at 1/15 sec handheld at 300mm, that's pretty amazing IS performance. Although it's a little soft at 300mm wide open, but stop down to F8, then it's very sharp. Some of the picture can even match to what I got from EF 100mm F/2.8 Macro. The 300mm is extremely helpful when shooting...

Canon's hidden L lens

Strengths: Image quality (!), 2-mode image stabilizer (IS), zoom range, light weight

Weakness: Average build quality, slow (f5.6 at 300mm), lens barrel extends when zoom, no lens hood (as usual from Canon)

Unlike its predecessor the 75-300 IS, this lens consistently produces very sharp images even under conditions when IS is not needed, which means by itself the lens design and quality is already an improvement. With the 2-mode image stabilizer (Mode 1 for stationary subjects; Mode 2 for tracking a moving subject) together with this good price (an unusual practice from Canon), it is not difficult...

Canon EF 70-300 IS USM Rocks!

Strengths: Lightweight; excellent IS with 2 modes; auto-focus fast; black finish; locking tab at 70mm for transport/storage

Weakness: None (not don't expect weight/feel of an L lens)

I purchased this lens (Canon EF 70-300 IS USM) for my Canon 20D, primarily for extended distance sports photos (soccer). Initial assessment is EXCELLENT - and a great value. The pictures are sharp, stunning and impressive. The autofocus worked flawlessly - even when taking fast action shots during soccer matches. And, the ability to hand-hold the camera at the 300mm extended range and get great...

Outstanding long range zoom with updated image...

Strengths: Lightweight, excellent build quality, great zoom range

Weakness: Front focusing ring a bit of a pain to use with a circular polarizer.

I just purchased this lens for my Canon Digital Rebel XT puppy and I'm extremely pleased so far. The pictures are sharp and stunning even when hand holding down to 1/60 sec. This lens is an updated version to Canon's 75-300 IS that's been out for quite some time. The major differences with this version are improved optics/glass and a 2 mode image stabilization, as well as the wider 70mm. Other...

A very good lens out there

Strengths: IS, range 70-300

Weakness: slow at 300, F4-5.6. rotating and extending front. manual focus is hard (not damped).

I bought this lens along with my 30D. I have to say this is a great lens, even compared to 70-200F4 or F2.8. Images are sharp, auto focus is dead on and reliable. IS rocks. I managed to shoot a Chinese evening perform from back seat at ~1/30, ~200-300mm, ISO 800-1600 with acceptable images. IS is really a plus. without IS, at 200 range, you can only in direct sun light, never in doors or at night...

Outstanding Zoom Lens, Excellent Value

Strengths: Very sharp lens, IS is terrific, fast auto focus speed, lightweight, inconspicuous black finish

Weakness: No lens hood, case, but to be expected for a non-L lens outfit.

I was considering the 70-200mm 4L lens but choose this instead because of: 1) Image stabilization 2) Light weight, compact lens. 3) Inconspicuous black finish compared with white L lens With the IS set on the "tracking" mode I was able successfully take a shot of a hawk flying overhead at the maximum 300mm zoom. Using my Rebel XT this was equivalent to a 480mm (1.6 crop) zoom!! Image detail was...

Canon Zoom Telephoto EF 70-300mm f/4-5.6 IS Image...

Strengths: Excellent in both setting of the IS. The USM is also very good.

Weakness: A little to bulky in the 300mm with the lens cover on it and in poor light not as clear as I would like however Adobe can correct that.

I use it for wildlife photography and it is excellent. I tried the 100 mm setting for portrait and was very pleased with the results. Would I sooner have had an "L" series lens? No, it produces too sharp and image and doesn't look natural. For the price I think it is an excellent lens
