Canon EF-S 17-55mm f/2.8 IS USM Lens

The Canon EF-S 17-55mm f2.8 IS USM Lens is unarguably one to the best mid-range “walk-around” zoom lenses one can get for their non-full frame EF line of Canon cameras.  With an image quality at par with some of Canon’s full frame L lenses and a three-stop image stabilization feature unheard of in its line, there isn’t a lens in its class that could possibly rival its versatility and range of features in terms of professional shooting standards.

The crop-optimized Canon EF-S 17-55mm f/2.8 IS USM Lens is well tailored to fit smaller image sensors on APS-C cameras.  This is clearly perfect for the EOS line with 1.6x crop sensors (like the 20D, 30D, 40D, 50D, 7D, etc.), the Rebel XT and Rebel XTi model cameras.  This S series lens is the key to making your APS sensor bodies capable of taking excellent professional level images.

Canon’s 17-55mm S lens, however, will not suit full frame and 1.3x digital cameras nor 35mm film cameras.  This lens will only fit Canon cameras with EF-S lens mounts.  Seeing a possible problem with this, Canon has thoughtfully provided a rubber ring in the rear that prevents inadvertent damage in case someone tries to jam the lens onto an EF mount.

Canon’s 17-55mm price is no joke but it does live up to the its reputation as the best kit upgrade or even perhaps, as the only lens you may ever need for your non-full frame camera.   Here is why:

Fantastic Image Quality and Wide Aperture:

Images are brilliantly crisp and absolutely sharp.  The Canon EF-S 17-55mm f2.8 IS USM serves up higher contrast pictures with vivid colors.  It takes far better photos than the Canon EF-S 18-135, one of those lenses in the same line it is so often compared with.  Images are also comparable to some full-frame L lenses like those of the 24-105/4L and the 35/1.4L as the EF-S 17-55 incorporates similar components as these high-end full frame lenses.

The aperture, f/2.8, is generously wide all the way through and makes for faster, extremely well taken shots in low light conditions.  Indoor shots are more natural looking as this lens eliminates much need for the flash feature.  Wide angle shots in the daytime are likewise superb with the lens’ Super Spectra coating which minimizes flare and ghosting.  Canon’s exclusive coating technology allows the sensor to absorb more light while reducing reflections to produce sharp, undistorted images with very good color balance.  Outstanding picture quality in many situations just proves that the EF-S 17-55 may be the only lens you may actually need in many situations.  Its acceptable weight is a plus as well over the heavier L lenses.

The wide aperture also allows you the versatility of creating beautiful bokeh, an aesthetically pleasing background blur that draws attention to the sharply detailed subject up front.  This produces wonderful portrait shots, with the best qualities you can squeeze from a midrange digital zoom lens.

Image Stabilization:

The Canon EF-S 17-55mm f2.8 IS USM Lens with its Image Stabilization feature, makes handheld photography a cinch.  No other lens in the EF-S line has been endowed with the three-stop IS feature, another advancement that makes the EF-S 17-55 a stand-out in its class.

Image Stabilization makes for an effectively faster lens, enabling you to shoot great pictures in dim light at low shutter speeds, provided the subject is still.

The IS feature basically corrects blurring caused by camera shake.  It compensates for vibrations and camera movements by maintaining a steady image plane, ensuring clear, intense images even under low light.  This does not rectify blurs, however, from fast moving subjects.

Full Time Manual Focus:

The Full Time Manual (FTM) focusing feature of the Canon EF-S 17-55mm f/2.8 IS USM Lens gives full control to the shooter.  You may move from auto-focus to manual focus instantly by simply rotating the manual focus ring.  You don’t need to switch auto-focus off or restart it after a manual override.  This is a nice feature that saves time and lets you progress from shoot to shoot without stopping for this adjustment.

The Ultrasonic Motor feature (USM) uses ultrasonic frequency vibrations to drive a super quiet, fast auto-focus motor.  In fact, USM is known as the fastest and most quiet auto-focus technology.  This is another edge this Canon lens has over other brands in its category.

Build Quality:

Not too heavy and not a feather weight either, Canon EF-S 17-55mm f2.8 IS USM is somewhere in the middle at 645 grams or 22.8 ounces. It is however, the largest EF-S lens in the market now at 3.3” x 4.4” or 83.5 mm x 110.6mm; but it balances well on camera bodies it was made for.

With a top-notch build quality, this lens is not much to worry about it.  Users who have continually used this lens over time attest to its durability in some weather conditions. The solidly constructed plastic body makes this a much lighter choice over the heavier metal-bodied L lenses which could weigh as much as 940 grams.

A lot of shooters from the huge fan base of Canon EF-S DSLRs have already taken to the Canon EF-S 17-55mm f2.8 IS USM Lens.  It’s a stellar lens that combines very good zoom range, low light capability, fantastic image quality, wide aperture for control on field depth, fast and whisper quiet auto-focus, a trove of features which sets it apart from all lenses in its class.

Known for its versatility, the EF-S 17-55 is a keeper.  There is hardly any lens out there in its category that can truly rival its features; so, as a sure high resale value lens, the EF-S 17-55 would  be a wise investment should you see a full frame camera upgrade in your future.

Having invented the world’s first 80-200mm f/2.8 in 1982, Nikon has become a byword in lens technology.  Every five years, they come up with better and better opticals so that today, we have one of the sharpest, fastest telephoto zoom SLR lenses with more focal accuracy and the least distortion-prone issues ever produced.  We are talking about the Nikon AF-S 70-200mm VR II.

The lens may be the most important purchase a serious photographer can make as it has perhaps more effect on the quality of the photo than the camera itself.  The best advice a serious amateur with a budget can listen to, is to think of the best lens he can get first before considering his camera.  SLR lenses can make or break your whole photo set-up, so don’t settle for cheap, average lenses if you can afford better ones.  Camera bodies lose value after several months and get upgraded often.  SLR lenses retain their value for quite some time and remain functionally current for a decade despite all the new camera models churned out.  This is why we should flesh out what makes the Nikon 70-200mm AF-S f/2.8G ED VR II a good decision.

Its predecessor, the VR I, has already proven its merits especially with professional wedding photographers.  The VR II, while heavier and about $500 more than its ancestor, boasts further refinements.

Photos from the Nikon AF-S 70-200mm VR II are ultra sharp and the colors, fantastically vivid and dynamic. Sharpness extends to the corners of a shot for superb landscape photography and even portrait shots when shooting off-center rule of thirds.

This much vaunted degree of sharpness is aided by the VRII’s Image Stabilization technology.  This Vibration Reduction enhancement optimizes every shot by effectively minimizing image blurs from camera shakes and allowing optimal shooting at low shutter speeds in challenging light conditions.  This feature is the lens’ best offer as it does spell out the difference in being able to shoot at maximal focal point without a monopod or tripod support.  There are two modes for this: Normal for everyday shooting conditions and Active for effectively decreasing vibrations when shooting from a moving vehicle or while on the run.

Nikon’s exclusive Nano Crystal Coat on this lens combats flares and ghosting to produce beautiful, high contrast images shot even in low-light environments.

In addition, there is a marked bokeh improvement in this model over the VR I.  Color and contrast is also much better with the Nikon AF-S 70-200mm VR II lens especially when subjects are backlit against the sun.

Focus is fast and silent.  This newest Nikon lens complements the latest auto focus technologies.  The Nikon 70-200mm AF-S f/2.8G ED VR II offers three modes: A/M, M/A, and M. Its fast response makes it marvelous to use for wildlife and action shots.  VR II also flaunts closer focus ability rated at 1.4 meters or 4.6 feet versus other Nikon f/2.8 SLR lenses of which the close focus limit is 1.5 meters or 5 feet.   Most full-time pros would not mind the extra cost of getting a half foot closer as the ability to shoot at a closer distance is worth the convenience, especially if they shoot for a living.

Built for serious shooting, the Nikon AF-S 70-200mm VR II sports a strong magnesium body, extremely sealed well against dirt and moisture to a withstand a wide range of weather conditions.  The shorter, more compact length and hood vis-à-vis the VR I’s makes it easier to pack and tote around in crowded spaces.

It is also a versatile choice for most Nikon bodies.  It works perfectly on those in the DX line and especially those in the FX family, as this is primarily a telephoto zoom lens for full-framed digital cameras.  It will also do very well on those of the D series (D40, D40x, D60, D3000, and D5000) and surprisingly, even on AF film cameras such as the F6, F100, F5, N80 and N75.  Just don’t push it with really older and cheaper film camera models.  Although it will work, you will lose some features.

Whether you’re a demanding pro or a serious amateur, you won’t go wrong with the Nikon AF-S 70-200mm VR II.  This high-performance lens addresses many image challenges inherent in sports, travel, portrait, wildlife, landscape and journalistic photography.  With all the features crammed into Nikon’s latest pro workhorse, this lens will be one of the best equipments you can ever own within the decade.
