Canon EF 50mm f/1.8 II Dslr Lens preview


Canon EF 50mm f/1.8 II Dslr Lens preview



















Technical Details

  • 50mm standard lens with f/1.8 maximum aperture
  • Traditional Gauss-type optical design is extremely sharp
  • Focuses as close as 18 inches for extreme close-ups
  • Ideal for natural-looking shots; excellent color balance
  • Measures 2.7 inches in diameter; 1-year warranty
Canon EF 50mm F1.8 II lens: Highly Recommended
        The Canon EF 50mm F1.8 II may be one of the cheapest lenses currently on the market, but its optics belie its lowly price. As befits a classic standard prime lens, it's very sharp when stopped down (especially in the centre), shows minimal chromatic aberration, and has relatively low distortion; APS-C users will also benefit from extremely low vignetting. In most regards it comes very close indeed to its much more expensive bigger brother, the EF 50mm F1.4 USM, lagging marginally behind in corner sharpness at any specific aperture. The only real blight in imaging terms is the lens's bokeh, or rendition of out-of-focus backgrounds, which is anything but smooth with a distinct tendency to render bright highlights as obvious pentagons (it's a pity Canon didn't choose to use a diaphragm with 7 or 8 blades instead of 5).

Product Description
       Product Description Lightweight and affordable, the Canon EF 50mm lens--which offers a fast f/1.8 aperture--is an excellent lens for people who prefer a fixed focal length. Canon's lightest EF lens at a mere 4.6 ounces, the lens boasts a traditional Gauss-type optical design that delivers a sharp performance even when wide open. As a result, the lens provides an image that's extremely close to how your eye perceives a subject, making it excellent for portraits and images that require a natural depth of field. In addition, the lens focuses as close as 18 inches, helping you take extreme close-ups. Finally, the lens offers an excellent color balance. As with all Canon lenses, the lens carries a one-year warranty.

Nikon 35mm f/1.8G AF-S DX Lens: Highly recommended

The AF-S Nikkor 35mm F1.8G DX is a lens which certainly caused a degree of dismay on its release, with many Nikon fans disappointed by the decision to make it compatible with the DX format only. However the main benefit of that decision is plain for all to see - even at its introductory price the lens costs rather less than the venerable AF-Nikkor 35mm F2.0D, despite the addition of an AF-S motor to allow autofocusing on Nikon's entry-level D40 / D40X / D60 bodies. It's also less than half the price of the few other DX format standard primes currently on the market (such as the Pentax 35mm F2.8 Macro, Tokina 35mm F2.8 Macro and Sigma 30mm F1.4 EX DC HSM), so Nikon has managed with this lens to produce the first genuinely inexpensive (sub-$200) fast standard prime designed specifically for digital SLRs.
