Canon EF 28-105mm f/3.5-4.5 II USM Standard Zoom Lens for Canon SLR Cameras

Canon EF 28-105mm f/3.5-4.5 II USM Standard Zoom Lens for Canon SLR Cameras

The Canon EF 28-105mm standard zoom lens retains the optical capability of Canon's previous EF 28-105mm USM lens but with a refined exterior design. The lens is distinguished by a ring-type ultra-sonic monitor (USM) drive that provides silent, high-speed autofocusing, along with full-time manual focusing. The 1.6-foot close-focusing distance, meanwhile, lets you take great close-up portraits and nature shots. A good match for the Canon EOS A2/A2e or ELAN 7 series cameras with built-in flashes, the Canon EF 28-105mm lens is an excellent zoom lens for everyday use. The lens carries a one-year warranty.

Product Description
The Canon EF28-105mm f/3.5-4.5 II USM retains the optical capability of the highly popular Canon EF 28-105mm f/3.5-4.5 USM lens, with a refined exterior design. Includes ring-type USM drive for silent, high-speed autofocusing, plus full-time manual focusing. The compact design is a good match for the EOS A2/A2E or ELAN 7/7E with built-in flash. An excellent zoom lens for everyday use.

The Canon EF 28-105mm f/3.5-4.5 II USM Lens is a definite step up in quality from Canon's econo consumer zooms.

The Canon EF 28-105mm f/3.5-4.5 II USM Lens should not be confused with the much-lower-end Canon EF 28-105mm f/4.0-5.6 USM Lens. These are much different lenses.

The Canon EF 28-105mm f/3.5-4.5 II USM Lens features good build and decent-for-the-price optical quality.

As can be expected, the Canon EF 28-105mm f/3.5-4.5 II USM Lens' cost is a notch above the econo zooms, but the notch is not a big one.

Canon EF 24-70mm f/2.8L USM Standard Zoom Lens for Canon SLR Cameras

Canon EF 24-70mm f/2.8L USM Standard Zoom Lens for Canon SLR Cameras

The Canon EF 24-70mm standard zoom lens does what many pros thought couldn't be done--it replaces the L-series 28-70mm f/2.8 lens with something even better. The lens offers extended coverage to an ultra-wide-angle 24mm, making it ideal for digital as well as film shooters. The new processing unit, meanwhile, makes the autofocus (AF) faster than ever. And thanks to the two aspherical elements and a totally new UD glass element, the optics are far superior to the earlier lens. Sealed and gasketed against dust and moisture, the EF 24-70mm lens carries a one-year warranty.

The Canon EF 24-70mm f/2.8 L USM Lens easily beats Canon consumer zooms (such as the Canon EF 24-85 Zoom Lens and the Canon EF 28-135 IS Zoom Lens) in direct sharpness and contrast comparisons.

Like most 24-xx zoom lenses, the Canon EF 24-70mm f/2.8 L USM Lens shows some barrel distortion on the wide end until disappearing around 35-40mm. This distortion is primarily evident on a full frame body. Vignetting is very well controlled, but apparent in the corners at f/2.8 at 24mm - primarily on a full frame body. Vignetting improves as the focal length increases and the aperture is narrowed. At comparable apertures, the 24-70 L shows less vignetting than the Canon EF 24-105mm f/4 L IS USM Lens- a typically expected result when comparing a fast lens to a slower lens. CA (Chromatic Aberration) is well controlled, generally only showing under harsh contrast conditions at the wide end of the focal length range.

A fixed f/2.8 minimum aperture makes this lens as fast as any Canon EF zoom lens made. The wide 8-blade aperture produces a nice background blur.

Bring small things into full-sized view with the Len Canon EF 60mm macro USM lens. Macro lenses can uncover detail that would be impossible to detect by the eye and give new perspective to extremely minute subjects such as insects or the petals of a small flower, and this lens is no exception. The 60mm lens offers an angle of view that's equivalent to a 96mm lens on a 35mm camera, along with a floating optical system that can focus down to life-size 1:1 magnification. The inner focusing system, meanwhile, is driven by a silent and powerful ring-type ultra-sonic monitor (USM), meaning the lens's overall length never changes during focus. Ultimately, the multi-purpose lens is equally at home shooting macro shots, portraits, or available-light photos. Like all Canon EF-S lenses, this lens is restricted to the EOS 20D, EOS Digital Rebel, and EOS Digital Rebel XT cameras.

* Focal length: 60mm
* Maximum aperture: 1:2.8
* Lens construction: 12 elements in 8 groups
* Diagonal angle of view: 25 degrees
* Focus adjustment: Manual
* Closest focusing distance: 0.65 feet
* Filter size: 52mm
* Dimensions: 2.9 inches in diameter, 2.8 inches long
* Weight: 11.8 ounces



Product Description

Canon must believe that the Len Canon EF-S 60mm f/2.8 Macro USM Lens is very durable as they include only a piece of double-thick corrugated cardboard and a bubble wrap bag for padding in the box. And it does appear to be reasonably well built. The focus ring is relatively wide and smooth functioning. The lens is relatively small and quite light - it feels very nicely balanced on the Canon 350D/Digital Rebel XT. The design looks and feels modern.

Len Canon EF 70-200mm F2.8 L IS USM

The Len Canon EF 70-200mm F2.8 L IS USM

The Len Canon EF 70-200mm F2.8 L IS USM was introduced way back in August 2001, supplementing (but not replacing) the non-stabilized Len canon ef 70-200mm F2.8 L USM in Canon's highly regarded telephoto lineup.

The Len canon ef 70-200mm is an EF lens, and has presumably been designed from the outset for optimum performance on Canon's professional 1-series DSLRs, with their full-frame 35mm and 1.3x crop (APS-H) formats (indeed the original EOS-1D was announced just a month after this lens, with the full-frame EOS-1Ds following a year later). However it's also fully at home on all of Canon's APS-C DSLRS, here providing a 112-320mm equivalent angle of view.

Len Canon EF 50mm F1.4 USM

Len Canon EF 50mm F1.4 USM

Len Canon EF 50mm F1.4 USM is Canon's mid-level offering in a range stuffed full of 50mm primes, covering all budgets from the ultra-cheap 50mm F1.8 mkII through to the stratospherically-priced 50mm F1.2 L USM. Although it was introduced in June 1993, fully seven years after the birth of the EOS system, it can actually trace its roots back much earlier, being based on the classic manual focus FD 50mm F1.4 design of 1971. As such, it's designed as a 'standard' lens for the 35mm full-frame format, with an angle of view offering none of the 'perspective distortion' associated with wideangle or telephoto lenses. More recently, with the popularization of APS-C as the dominant DSLR sensor size, it's taken on a new role, and behaves like a short 'portrait' telephoto on this format.

The lens canon uses a conventional optical design for its class, with 7 elements in 6 groups, two of which are made from high-refraction glass. Focusing is achieved by an ultrasonic motor system, with full-time manual override; however unlike Len Canon's other mid-range primes, this is of the micro-USM (as opposed to ring) type. Canon claims the lens canon produces a 'beautiful, natural blur of the background', an important attribute for a fast lens capable of a high degree of subject isolation. The company is also keen to point out that the lens's colour balance is virtually identical to the ISO recommended reference values.

The Len Canon EF 50mm F1.4 USM has always occupied a slightly precarious position in the Canon line-up, with the F1.8 lens offering remarkable value for money below it in the range. It now faces fresh pressure from Sigma's 50mm F1.4 EX DG HSM with its brand-new, bang up-to-date optical design (albeit currently at a far higher price).

Len Canon EF-S 18-200mm 1:3.5-5.6 IS

Len Canon EF-S 18-200mm 1:3.5-5.6 IS

Len Canon EF-S 18-200mm F3.5-5.6 IS is Canon's latest zoom lens for APS-C format DSLRs, introduced as a companion to the EOS 50D. Its announcement in August this year came as no great surprise, as wide focal length range 'superzooms' are clearly popular amongst photographers seeking an all-in-one lens for travel and everyday shooting. The most obvious example of this is the runaway success of Nikon's AF-S 18-200mm F3.5-5.6G VR, and Len Canon equivalent has almost certainly been the most-requested lens on our forums.

With its 11x zoom range, the 18-200mm becomes Len Canon's most ambitious consumer-level zoom to date; the company has previously shied away from producing relatively inexpensive superzooms, with its only previous foray into this sector being Len Canon 28-200mm F3.5-5.6 (USM) for 35mm SLRs from late 2000. And while it's this older lens that Len Canon 18-200mm most strongly resembles, Canon has managed to squeeze plenty more into the design in the intervening eight years. The zoom ratio has been stretched to a 35mm-equivalent range of 29-320mm, and the new lens incorporates Canon's latest compact image stabilization unit (as seen on len canon EF-S 18-55mm F3.5-5.6 IS and Canon EF-S 55-250mm F4.5-5.6 IS), which offers automatic panning detection and (according to the company) four stops of stabilization. All this has been achieved using a suitably complex optical design of 16 elements in 12 groups, including two UD glass elements and two aspherical elements which are designed to minimize chromatic aberration and ensure crisp corner-to-corner detail across the zoom range. Rounding off the specification is a minimum focus distance of 45cm/1.5ft at all focal lengths.
