Canon EF 70-200mm f/4 L IS USM Lens for Canon Digital SLR Cameras |
| Product DescriptionCanon EF 70-200mm f/4L IS USM lens offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 200mm without having to decrease shutter speed. Developed for use with a Canon SLR camera, this autofocus telephoto zoom lens offers optimized use with the Canon EOS series digital cameras. Of particular note, Canon has introduced an image stabilizer (IS) that adjusts to meet the demands of professional photography. IS reduces dramatically the image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane. For shooting immobile subjects, Mode 1 corrects for movement in the image along both the horizontal and vertical axes. For shooting while panning horizontally to follow a moving subject, Mode 2 turns off vertical correction and prevents the effect of dragging the subject back through the frame. The lens' Ring-type USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. A powerful CPU and improved AF algorithm contribute to speed performance. The EF 70-200mm f/4L IS USM includes distance metering information, providing compatibility with the E-TTL II flash system of late model cameras such as the EOS-1D Mark II, EOS-1Ds Mark II, EOS 5D and EOS 400D. When used in conjunction with Canon's range of EX Speedlite flash units, the lens passes distance information to the flash algorithm for markedly improved flash exposure metering. Includes Lens hood and soft pouchAmazon.com Product DescriptionCapture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 70-200mm telephoto zoom lens. The L-series lens offers an Image Stabilizer that provides up to four stops of shake correction--a first for Canon IS lenses. The use of fluorite UD lens elements, meanwhile, produces an excellent optical performance in terms of resolution and contrast. Add in a sturdy housing with water- and dust-proof construction and you have a lens that's both portable and high performing. Other details include an f/4 maximum aperture, a ring-type ultra-sonic monitor (USM) that enables quick and quiet autofocusing, compatibility with circular polarizing filters, and a lightweight body. The lens carries a one-year warranty. - Focal length: 70-200mm

 | | MTF Charts | ReviewsI got this lens for less than a week and have shot about 300 pictures with it. So far I'm very happy with it.
This is my very first L-lens. The only other lens I've got is the 28-135 f/3.5-5.6 IS kit lens that came with my 50D camera. So here, I'll try to give you my impression of this lens in comparison to the 28-135 lens.
Construction quality - This lens is cream white with black stripes where the focus and zoom rings are. It is solid and doesn't wobble like the kit lens. The first time I turned the zoom ring it almost freaked me out...it was so smooth and without any friction. I still have trouble believing it can be physically made that smooth --> impressed...it's like driving a Mercedes after years of driving a Camry (which I also did)...no actually even better...Similarly, the switches (e.g. focus distance, AF --> MF, ...) are much smoother.
Picture Quality -- So far, picture quality is really good but to be frank, it isn't improved by leaps and bounds compared to the kit lens (in the zoom ranges that are comparable)...it didn't wow me like the mechanical construction did. I guess the kit lens is very good in this area.
Portability -- this lens is quite small and light (it is slightly skinnier than the 28-135 kit lens but a few inches longer and very long with the hood on). Today I walked 6 miles with it on the 50D and didn't feel tired due to its weight at all. One thing I noticed, the leather bag that comes with the lens is way too big.
Image Stabilizer -- The IS appears to work quite well. It makes a lot more noise compared to the kit lens which was a surprise. You can hear it working (starting up and shutting down) quite distinctly. I guess it has something to do with the 4 f-stop capability versus 3 or less of other lens. I haven't tried the IS Mode 2 yet so I can't report. I panned with Mode 1 and the result was quite OK.
The autofocus -- There is a switch that allows you to switch from 1.2m-infinity and 3m-infinity. The default was at 1.2m-infinity. I shot about 150 shots of birds in flight at 200mm with the switch at the default and the camera on AI SERVO and high speed (6.3fps)...Out of these 150, the lens couldn't focus on the bird in about 30 shots. With the kit lens (no such switch and at its max 135mm), it only fails in about 5 out of 150. I was disappointed until I remembered there was this switch. After switching to 3m-infinity, I shot about 50 pictures and I had zero focusing failures...I'm happy with this discovery. The lens manual says switching to 3m allows faster focusing and it wasn't kidding...so my recommendation is to do so. I'd only switch back to 1.5m if I need to focus objects closer than 3 meters. The USM motor is faster, quieter and much smoother than the kit lens's.
Prior to getting the 50D DSLR, I used a Canon 10SX-IS that has an 35mm-equivalent 600mm zoom. I miss the reach...This lens is only 200mm, even with a crop camera body (equivalent 320mm), sometimes it didn't have enough reach for these darn birds...they are too small and far away :). Other than that, this lens is a clear winner. Like someone said...once you own an L lens, you'll never go back.
I purchased a Canon 50D beginning of this year with the kit lens (28-135). My first step up from a 35mm Pentax ME Super and boy am I ever enjoying photography more now! No more worries about enough film. After that purchase I next purchased a 17-55 2.8 lens. Never having a lens that fast before put me at another level. I always spend a lot of time researching before I buy camera equipment, or anything for that matter, and my next wish was a "L" lens. Since I started in photography back in 1984 I've found this hobby to be very addicting. This 70-200 4.0 IS zoom is awesome. I've only had it 3 weeks and I've shot over 400 pictures and I love it. When I've used it the way I'm supposed to the pictures are awesome in the camera. Canon prices are very expensive but ....... quality comes with a price. I highly recommend this lens if you can afford it.
All the good praise given for this lens is deserved. This is my 7th L lens, and it immediately has become my favorite. I like it much more than my f2.8 28-300L IS, which requires a tripod for me to use. I thought that the extra stop in the 2.8 version of this lens might be useful enough to warrent the extra expense, but after reading the reviews of the f4, I gave it a try. I am glad that I did not spend the extra money for a feature that does not seem to be needed. The quality of the pictures taken by this lens is just wonderful. My only regret is that I did not make this my first L lens.
Much deserving praise has been heaped on this lens, and I can't help but contribute more, but I'll also try to explain why in the vast world of telephoto zoom lenses, this is the one you should pick.
First off, compared to its non-IS cousin, this lens offers an amazing four stops of stabilization. If the rule of thumb for shooting 200mm says shoot no slower than 1/250th of a second (the nearest stop above the reciprocal of the focal length), and four stops slower is 1/15th. Obviously this is slower than you'll likely need to go, but that's how good this IS is. It is among the best Canon offers.
The other obvious choices for comparing this lens are the 70-200mm f/2.8 non-IS and f/2.8 IS versions. Without IS, the f/2.8 price is the same, yet even if you can afford the $2,500 version, this f/4 IS is still, in my opinion, the best choice. Yes, the f/2.8 versions give a full extra stop of aperture, an advantage which should not be discounted, but the drawbacks of using those lenses are their far greater heft. For one stop of aperture, you'll be toting up to double the weight. The f/4 version can still fit in camera bags, the f/2.8, not so much.
Other options you may be considering are the Canon EF 70-300mm f/4-5.6 IS USM Lens for half the price, or the Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens which goes for about the same price. While these lenses do give a little extra "reach" going to 300mm, you'll not miss it. On the contrary, with the 70-200mm f/4L IS you will greatly appreciate the much greater image quality (including sharpness and contrast), the aperture that doesn't change with zoom amount, the amazing easiness of use, and the lens barrel that doesn't change in length when zooming that come with this nicer lens.
This non-changing lens length should not be discounted -- using it is like a breath of fresh air, and you will never go back. Not only does the focal length never zoom on its own, but you never have to "store" the lens at a set focal length.
This is my absolute favorite lens for nature and event photography. It comes with the lens hood, and I personally have accessorized it with a Janco Metal Tripod Collar Mount for ease of use, and a B+W 67mm UVA Haze MRC Filter #010.
