Product Description

Product Description

With extra low dispersion glass and original lens coatings, this lens is superior in contrast, clarity and edge-to-edge sharpness.

Amazon.com

Boasting such features as super-low-dispersion optical elements, extra-low-dispersion (ED) optical elements, and Pentax original lens coatings, the Pentax DA* 55mm f/1.4 lens delivers crisp high-contrast images even at the edges. The lens is outfitted with a water- and dust-resistant seal for reliable operation in inclement conditions, along with a Pentax Quick-Shift Focus system that allows you to instantly switch between auto and manual focus. The objective lens surface, meanwhile, is treated with Pentax original (Super Protect) SP coating, a special fluorine compound that's applied through a vapor-deposition process to create a surface that effectively repels dust, water, and grease. The combination of special lens coatings, ideal curvature, and superior positioning of optical elements optimizes a host of digital imaging characteristics while effectively minimizing flare and ghosting. Other features include an Aero Bright coating for maximum light transmission, rounded diaphragm blades that create a more circular aperture, a fast f/1.4 aperture for outstanding depth-of-field control, and a 1.48-foot minimum focusing distance. An ideal lens for portraits, still life, or low-light photography, this Pentax 55mm lens carries a one-year warranty.

For example, they mention that it gives far more natural colors, the bokeh is smooth and dreamy, and the focusing is almost silent. That said, they say it's well worth the price. Customers are also impresseded with the weather resistance, build quality, and sharpness.

Pentax 55mm Prime
I am a pro-amateur photographer and this is the first prime lens I've ever purchased. I currently own an all-Pentax system, including a K200D body with all the other SMC DA* lenses except the 200mm. My intention in buying the 55mm was to have a razor-sharp lens for candid and formal portrait photography. I've shot close to a hundred pictures with this wonderful lens over the course of the past couple of weeks, and it's ability to capture images in low light is awesome at f/1.4, but not quite as sharp as when set to f/2.0. It has marvelously creamy bokeh in the low f-stop range, including a truly magical ability to capture shading and colors not perceived by the human eye. Although I really love this lens, it probably gets a little less time on my camera than others, due to the fact that I still like the flexibility of zooms (the SMC DA* 50-135mm being a magnificent example!)I highly recommend this for anyone wanting to experience the minimalist pleasures of a prime lens. That is, if you're willing to shell out for the SMC DA's amazingly quiet motor and superior build quality as compared with it's less glamorous brother, the 50mm f/1.4. Believe me, after trying both, the SMC DA* is worth the expense, and it capably delivers absolutely gorgeous image quality in the right hands. Five stars all the way, and kudos to Pentax.

Un objectif ouvrant à f/1.4 et tropicalisé pour être paré aux imprévus.
Que demander de plus.

Pour rappel, un 55mm "Full Frame" est équivalent approximativement à un 85mm sur la majorité des Reflex (Capteur APS-C).
Si vous avez besoin d'être très proche de votre sujet lors du shooting, cherchez plutôt un objectif grand angle.
Si vous pouvez prendre un peu de recul (2-3 m), cet objectif fera votre bonheur !
