Canon EF 100-300mm f/4.5-5.6 USM Telephoto Zoom Lens for Canon SLR Cameras for

Customer Rating :

List Price : $470.00 Price :

Product Description

Highly practical and portable telephoto zoom lens. The five zoom groups make the length only 4.8 in. (121.5mm). With rear focusing, the lens does not change length or rotate during focusing. Any filter effects therefore remain intact. It also makes autofocusing quick and quiet.

Hairong Shi (Iowa City,IA USA) - See all my reviews

This review is from: Canon EF 100-300mm f/4.5-5.6 USM Telephoto Zoom Lens for Canon SLR Cameras (Electronics)

This lens is very good. Picture is very sharp with 100-200 mm. and it's perfect for head&body portrait. I love this lens. In 300 mm area you can see softness but it's not much.

And I compared with 28-105,this one is sharper at 100 than28-105 @105, and it shows much less distortion.

Compared with 75-300mm USM, this one seems sharper than 75-300, with the focus speed almost the same.

Of course, there are other better ones(like 70-200 f2.8L or other fixed focal telephoto lenses), but look what you pay for, it's really a good deal for amateur photographers.

Best tele-zoom in its price range, June 14, 2004

By A Customer

This review is from: Canon EF 100-300mm f/4.5-5.6 USM Telephoto Zoom Lens for Canon SLR Cameras (Electronics)

Very light and compact. This makes a great "traveling" lens. I take about 15% of my pictures with this lens, mostly out on hikes where I don't want to haul around my expensive & heavy 70-200 f/2.8 L. This lens paired with an EF 28-105 f/3.5-4.5 USM or EF 28-135 f/3.5-5.6 IS USM will give you a compact, light-weight package that you can take along on trips or nature hikes, and cover all of the useful focal lengths.

Much better image quality than Canon's EF 75-300 lenses. Ring USM for fast auto-focus, but no image stabilization. Good build quality for the money spent.

Sharpness drops off noticably past 200mm or so, with some flaws around the edges, but images are still acceptable for the most part. Great lens for 10D/Rebel/300D digital cameras, since the 1.6x cropping will eliminate the flaws at the egdes of the picture at the longer focal lengths, and make this lens effetively a 150-450mm.

Best used stopped down to f/8 or f/11, in good light or with fast film (or... Read more

Great value for price; some caveats on performance, November 15, 2004

Richard B. Williams "huge nerd" (Los Alamos, NM USA) - See all my reviews

This review is from: Canon EF 100-300mm f/4.5-5.6 USM Telephoto Zoom Lens for Canon SLR Cameras (Electronics)

I bought this lens along with a 28-105mm zoom to get a wide coverage of focal lengths for as little money as possible. At the same time, I wanted to maximize my sharpness at 300mm for bird and astronomy photography. If this is your goal, then this is the perfect lens. It is significantly sharper than the 75-300mm lens at 300mm, while still staying under $300. If saving money is your absolute priority, then go with the 75-300mm.

In the end, I have become dissatisfied with the sharpness at 300mm. As stated in other reviews, it really drops off after about 200mm. At full zoom, I am finding the softness intruding on my pictures so I have started using it only as a 100-200mm zoomer. The 1.6x crop on my Canon 300D makes up for this somewhat, but it's still a bit of a letdown.

Another aspect of this lens that I have found aggrivating is the tendancy for the lens to zoom/unzoom itself if mounted vertically. The weight of the forward elements is suffient to... Read more

Bang for few bucks..., May 14, 2005

Careful Critic (Lexington) - See all my reviews

This review is from: Canon EF 24mm f/2.8 Wide Angle Lens for Canon SLR Cameras (Electronics)

This is a cheap lens - old design, very plastic - that can prove terribly useful for those on a budget who want a wider perspective, especially on 1.6x crop factor dSLRs.

I learned about "cheap" with this lens - broke the focus ring the day after delivery. But I blame myself too, and the replacement's given me no trouble, though I think my first one was a bit sharper than the second. (Update: calibration of the replacement optimized my performance to match or exceed that first one that I broke. It now performs *very well* wide-open at f/2.8, and beyond belief at f/5.6.)

By many standards, this lens will match or exceed zoom lens of comparable price (as a prime lens should). Autofocus is a little buzzy, but the main time you'll notice is when it loses its bearing and suddenly lurches way off target. Mostly, focuses quickly enough and well. Some chromatic aberration in worst-case scenarios, but nothing awful or unexpected. Vignetting, even on a 1.6x crop,... Read more

Mr. A. Pomeroy (Wiltshire, England) - See all my reviews

This review is from: Canon EF 24mm f/2.8 Wide Angle Lens for Canon SLR Cameras (Electronics)

I was on the lookout for a good-quality autofocus wide angle lens for my Canon 5D MkII, and this seemed to be the best option. Canon's telephoto lenses are generally superb and they make some good zooms, but the company has traditionally had trouble with the wider focal lengths. I can't justify the expense of a 24-70mm f/2.8 or the 24mm f/1.4, and the 17-40mm and 16-35mm seem either underwhelming or too specialised for what they are. The 28-135mm didn't appeal to me, ditto the 20-35mm f/3.4-4.5, the 24-85mm didn't impress me when I owned a copy. The non-L wide primes include the 20mm f/2.8, which no-one seems to like; the 35mm f/2, which lots of people like but doesn't seem great in the full-frame corners; the 28mm f/2.8, which I have tried and hated, and the 28mm f/1.8, which doesn't appeal to me at all. The 24mm f/2.8 seemed to be the dark horse, based on the tests I have seen, and so I found one cheap and snapped it up.

It is surprisingly good. Not excellent, but... Read more

If only vigneting could be reduced..., December 6, 2005

Gabriel Massip Fons (Catalonia) - See all my reviews

This review is from: Canon EF 24mm f/2.8 Wide Angle Lens for Canon SLR Cameras (Electronics)

I bought this lens to have a fixed, light lens to use with my digital EOS 10D (due to 1.6 crop factor it has the same viewing angle than a 45 mm lens, in the "standard" range). I use it in "keep it simple" photographic sessions.

Resolution and overall image quality are quite decent; but it has one main drawback: vigneting is non-negligible at f/2.8, even inside the digital cropped frame (so I can't guess how bad could it be in a full 35 mm frame). At f/4 it becomes usable. I've done a very informal comparison with Canon EF 17-40 L and both lenses give comparable results at f/4.

Design is old, but effective; it has a depth of field scale. I'd like it to have a more silent focus engine, or a somewhat more robust build, but it does its job.

erugifog "erugifog" (Seattle, WA USA) - See all my reviews

This review is from: Canon EF 24-70mm f/2.8L USM Standard Zoom Lens for Canon SLR Cameras (Camera)

I've owned the 24-70mm for almost a year now. This lens has been a favorite of many since it replaced its well-regarded predecessor, the 28-70mm. It shoots images that are very sharp and have excellent contrast and saturation. It's sharp wide open and only gets better when stopping down. The USM (Ultrasonic Motor) focuses very fast, and full-time manual focusing is allowed. I've thought about buying a 50mm f/1.4, but the results from this lens are so good, I'm having a hard time justifying the purchase. I've been nothing but pleased with the pictures I get from the 24-70mm. The constant f/2.8 aperture is great for shooting indoors and produces a very nice bokeh (background blur) when shooting portraits. This lens is much heavier than comparable consumer-grade zooms, but I don't object to the weight. I actually like the heft and feel of this lens on my 20D. The only feature I wish it had is IS (image stabilization).

The one thing preventing an unqualified... Read more

Eric Strate Photography (Spokane, WA United States) - See all my reviews

This review is from: Canon EF 24-70mm f/2.8L USM Standard Zoom Lens for Canon SLR Cameras (Camera)

UPDATE - October 3: Wanted to update my review on this lens after using it for a couple weddings and portrait shoots lately. Normally, these wouldn't warrant an update for a lens that is so obviously well-suited to these roles, but this lens literally saved the day. I was shooting a wedding in one of the most difficult type of circumstances - never seen the location before, had 15 minutes before the ceremony to scope things out, had no chance to get my basic flow figured out by watching a rehearsal and this place was an exposure nightmare - black tuxes, white dresses in a very poorly lit chapel. I was shooting with a backup camera (50D - great camera, read my review, but it doesn't perform well enough at high ISO for me to trust it for a wedding shoot as I don't want any noise introduced into things.) So I knew I was going to be limited to some extent in terms of the freedom I'd have to play with different F-stops - I was going to need to be wide open to shoot at an ISO that I... Read more

You will not be sorry you bought this!, February 11, 2006

Larry Kottraba (Phoenix, AZ USA) - See all my reviews

This review is from: Canon EF 24-70mm f/2.8L USM Standard Zoom Lens for Canon SLR Cameras (Camera)

In April of 2005 I bought the Canon 20D with the 18-55 kit lens, my first SLR camera. After getting used to properly taking pictures with the camera I bought the 24-70 as a lens upgrade - and what an upgrade it is. All the positive stuff you read about this lens is true ... the color, the contrast, the sharpness, it's unbelievable how well this lens performs compared to a consumer grade lens.

A lot of reviews complain that the 24-70 is too heavy, and it is heavy for a lens, but it's not "too" heavy to carry around all day. I also regularly use my Canon 70-200 f/2.8 IS - that's a lens that is maybe too heavy for regular use but it's also A LOT bigger than the 24-70.

A note about debates you'll find everywhere comparing the 24-70 to the new Canon 24-105 f/4 ... These lenses are not built to be an either-or, they are different lenses targeted at different uses. The main complaint I found online about the 24-70 is that it lacks Image Stabilization, a complaint I... Read more
