亚博国际网址tokina opera represents a series of next generation, premium full-frame lenses for high-end dslr cameras. the new series perfectly matches recent high-resolution full-frame dslr cameras that demand the highest quality optical designs. built on the award winning heritage of tokina's at-x line, the new opera series will offer an ever-expanding, premium line of full-frame lenses that meet the growing demands of high-performance dslr cameras.
in modern society the word "opera" is commonly used to indicate stage art works that combine drama, music and dance. in italian, it means work or work of art. as an omitted art genre definition, opera comes from "opera musicale", which means a piece of music work. in latin, opera comes from "opus" that is still used in contemporary language meaning "great literary, artistic or intellectual work" (e.g. "magnum opus", "opera magna"). we chose the name opera for our new premium full-frame dslr lens series with the idea that it will help the photographer in creating real "works of art".
"The most important challenge for every lens gear is going through extremely different and severe climatic conditions: whether it is crazy hot or freezing cold.
I tested opera 16-28mm F2.8 FF in quite severe cold conditions of Arctic and the lens showed great results. Fast and accurate focusing confronted low temperatures. Very high contrast and sharpness even at aperture wide open. The only thing that this lens faced difficulties with was manual switching from manual to auto focus modes. When shooting an aurora in the North Pole the One Touch Focus Clutch mechanism of the lens was moving tight, but that did not affect much my overall workflow."
"An excellent all-around ultra wide angle lens, with bright constant f/2.8 aperture and a very usable focal length range that can be used with great results in many different genres of photography, packed in a premium and robust, although a little heavy, body."
opera 16-28mm f2.8 ff is a super wide zoom lens featuring super wide angle at 16mm and traditional wide angle at 28mm that stands at the border where the standard zoom angle range begins, thus providing the photographer practically full wide angle coverage with only one lens.
亚博国际网址super wide angle, superior resolving ability coupled with high contrast and beautiful bokeh rendering, fast f/2.8 constant aperture throughout the zoom range and accurate af drive system make this lens attractive for photographers who specialize in landscape, interior architecture, street snap, documentary, environmental style portrait and night sky/time lapse photography genres.
opera 16-28mm f2.8 ff is available for nikon f and canon ef mounts.
亚博国际网址the new tokina opera 16-28mm f2.8 ff incorporates a complex optical design with 15 elements in 13 groups, 3 of which are of aspherical type including large aspherical p-mo element and 3 are glass low-dispersion (sd) elements for effective suppression of chromatic and spherical aberrations.

this optical design performs just optimal resolution at the aperture wide open that greatly increases by stepping down to f/4 and narrower. to make the lens suitable for landscape shooting and bw photography, engineers made maximum efforts to realize high level of contrast and rich color gradation in the image.
亚博国际网址The "bulb-like" shape front element cannot allow to attach photographic filter, but greatly contributes to low distortion and low light falloff. Superior color rendering will allow the photographer to capture the nature scenery in rich blue colors without using C-PL filter, and the in-built hood petals will serve as a protection from accidental damage of the front element.
due to well handled spherical aberration, tokina opera 16-28mm f2.8 ff creates gentle bokeh rendering at 28mm tele side, making this lens standing apart from other super wide angle lenses.
the new tokina opera 16-28mm f2.8 ff has been designed to provide the photographer comfort and confidence during the shooting. the lens comes in a sophisticated, gorgeous but yet simple and slim housing with well balanced zoom and focus ring arrangement. opera 16-28mm f2.8 ff is designed to fit top class dslr cameras and by no means meant to be light-weight and compact. it is the lens that, once hold in hand, makes the photographer realize himself involved into the shooting process and is suggested for those who are serious about photography.
the directional rotation of the focus ring matches the direction of proprietary nikon and canon lenses.
亚博国际网址the lens uses silent drive module that allows the lens to focus speedy and quietly. this dc motor, coupled with a new gmr magnetic af sensor, works together to increase af speed and accuracy.
亚博国际网址Tokina's exclusive One-Touch Focus Clutch Mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the lens mount for manual focusing.
