On note que la distance minimale de mise au point en près de moitié moins importante avec le 70-210 mm qu'avec le 70-220 mm (post suivant) : 0.9 m contre 2 m. En revanche, en mode macro, la distance minimale de mise au point est plus courte avec le 70-220 mm : 57 cm avec ce dernier contre 90 cm avec le 70-210 mm (la même que la distance minimal en mode classique). En se limitant ici à ces deux objectifs, il faut également tenir compte du rapport de reproduction. En photomacrographie le rapport doit être de 1 : 1. Ici, et pour l'ensemble des zoom Osawa, le mode macro est un mode de photo rapprochée. Et ce, plus ou moins. Avec le 70-210 mm, le ratio de reproduction est de 1 : 3, alors que pour le 70-220 il est de 1 : 6.

Pentax Lenses HD Coating Technology for Pentax K-Mount cameras


Pentax recently introduced its newly developed HD Coating technology – a multi-layer lens coating process – for all new HD (High Definition)  Pentax lenses for Pentax K-Mount cameras.

Compared with conventional multi-layer coatings, the new multi-layer HD Coating,* exclusively developed by  Pentax, offers much improved light transmittance and a much lower refractive index. Because this advanced coating minimizes reflections, the lens delivers sharp, clear images free of flare and ghosting, even under demanding lighting conditions such as backlight. This coating assures optical performance almost equal to Aero Bright Coating, another  Pentax-exclusive lens coating process made possible by advanced nanotechnology and applied to higher-class lenses.

Also introduced last week by Pentax is the new K-Mount HD  Pentax DA 560mm F5.6 ED AW interchangeable super-telephoto lens and the new HD  Pentax D FA 645 Macro 90mm F2.8 ED AW SR interchangeable lens for the medium format 645D – the first lenses to feature this exclusive  Pentax HD Coating. All future interchangeable lenses for Pentax digital cameras that feature this new coating will bear the “HD PENTAX” name.

Pentax' HD Coating technology Features include:

- 50 percent reduction of reflections in visible spectrum
The coating reduces reflections by more than 50 percent over the entire visible spectrum, compared to conventional multi-layer coating. 

- High rigidity coating layer
Since the HD Coating has a stronger bond among its coating materials and a higher packing density, this coating layer ensures exceptional high rigidity for extra durability.

- Accurate reflection of design concept to actual coating layer
In conventional multi-layer processes, the coating layer is produced by the vacuum evaporation method, in which coating materials are dissolved and deposited in a vacuum. This method, however, sometimes causes coating unevenness great enough to affect image quality. 

The HD Coating* effectively solves this problem by employing a Pentax-exclusive manufacturing process, while optimizing the density of its coating layer and controlling the thickness with the accuracy of one nanometer (one millionth of a millimeter). As the result, the original design parameters for the lens coating are accurately applied to the coating layer to optimize anti-reflection performance of a lens.

* HD stands for High Definition, and signifies the lens’s capacity to reproduce images that excel in transparency, definition, resolution and rendition.

Comparison between conventional multi-layer coatings and HD Coating:


The coating reduces reflections by more than 50% over the entire visible spectrum, compared to conventional multi-layer coating. The new coating allows an ideal control of color balance thanks to stable Reflection at Wavelength.

Carl Zeiss New CP.2 Super Speed lenses presented at NAB 2012

Three new Super Speed cine lenses are presented by Carl Zeiss at NAB 2012 : the Compact Prime CP.2 35/T1.5, Compact Prime CP.2 50/T1.5, Compact Prime CP.2 85/T1.5 Super Speed

Available with a fast T1.5 aperture and in focal lengths of 35mm, 50mm and 85mm, the new Compact Prime CP.2 Super Speed lenses offer filmmakers new opportunities for shooting in low-light conditions. Like the other Compact Prime CP.2 lenses, the new Super Speed lenses cover a full-frame sensor format and are equipped with the interchangeable lens mount system for use with a variety of cameras ranging from HDSLR to professional cinema cameras.

“With the new Compact Prime CP.2 Super Speed lenses with a fast T-stop of T1.5, we expand our family of CP.2 lenses with an even more powerful choice of lenses”, says Michael Schiehlen, Sales Director of the Carl Zeiss Camera Lens Division. “This opens up new creative possibilities in low-light situations, especially with the new high ISO HDSLR’s and HD video cameras. The Super Speed name has a long history at Carl Zeiss and these new lenses are a fitting tribute to their legacy”.

The faster T1.5 aperture is one of the key advantages to the Compact Prime CP.2 Super Speed lenses, especially for night-time shots or under low-light conditions. This helps to limit the need for artificial light, delivering more natural looking scenes with less effort and expense.

The cinematographer Sebastian Wiegärtner has tested the Compact Prime CP.2 Super Speed lenses and was very enthusiastic about the faster aperture while shooting a short film: “We filmed for three days in outdoor locations, with about eighty percent of the shots being taken at night. During the medieval-looking filming of two actors, the faster aperture was particularly effective by using lighting accents in the form of torchlight. The resulting images achieved the desired look and were appropriately stylish and soft.”

As with the rest of the CP.2 family, the Compact Prime CP.2 Super Speed lenses feature a 14-blade aperture, which creates a round iris opening and a natural, out of focus rendition. The standard cine-style housing with gearing allows the attachment of any standard follow-focus system. A long, 300 degree focus rotation and smooth action provides fine control, which is especially important given the shallow depth-of-field when using these lenses at wide open aperture. By using the interchangeable mounts for PL, EF, F, MFT and E, the Compact Prime CP.2 Super Speed lenses can be easily adapted to numerous camera systems and ensures compatibility with future cameras as technology changes. Carl Zeiss T* anti-reflection coating ensures the maximum contrast and color rendition by minimizing stray light and ghosting within the lens.

The Compact Prime CP.2 Super Speed lenses can be purchased individually, or combined as set with other Compact Prime CP.2 lenses in the product line.

The lenses will be shipped in August 2012. The recommended retail price for the Compact Prime CP.2 35/T1.5 Super Speed is €3,700 or US$4,900 (excluding VAT)*. The recommended retail price for the Compact Prime CP.2 50/T1.5 Super Speed and Compact Prime CP.2 85/T1.5 Super Speed is €3,300 or US$4,500 (excluding VAT)*.  * Status: 16 April, 2012

Nikkor Brand - Nikon's Photographic Lenses name explaining

Nikkor is the brand name for Nikon’s photographic lenses, which was created by adding an "R" to "NIKKO”, an abbreviation of Nippon Kogaku K.K., the original company name of Nikon Corporation at the time of its founding. In 1933, Nikon marketed its first camera lens under the NIKKOR brand name, the "Aero-NIKKOR” for aerial photography applications. Since then, Nikkor has been used as a brand name for Nikon’s lenses that symbolizes durability, high image quality and optical excellence.

With a comprehensive assortment of FX and DX-format lenses and focal lengths, from the ultra-wide 10-24mm to the super-telephoto 600mm VR, Nikon photographers have come to rely upon the Nikkor core technologies.

Canon produces 30-millionth EF lens

Canon announced the achievement of a new lens-production milestone as production of the company's EF lenses passed the 30-million mark
Production of interchangeable EF lenses for Canon EOS-series AF (autofocus) SLR cameras began in 1987 at the company's Utsunomiya Plant. Canon produced its 10-millionth EF lens in August 1995, its 20-millionth in February 2001 and, a mere five years later, has now reached the 30-million plateau. This achievement reflects users' high level of satisfaction with the performance and quality realized by EF lenses, as well as the service offered through Canon's marketing operations.
Canon's proprietary EF (electro-focus) lens, which combines a large-diameter fully electronic lens mount and an internal autofocus motor, was born in 1987.
In November of the same year, Canon introduced the industry's first [1] Ultrasonic Motor (USM)-powered lens: the EF 300mm f/2.8L USM.
In September 1989, the EF 50mm f/1.0L USM, featuring the world's largest aperture [1] of f/1.0, was launched and in September 1995 the EF 75-300mm f/4-5.6 IS USM, equipped with the world's first [1] Image Stabilizer to correct for the effect of camera shake, made its debut.
Further, in December 2001, Canon delivered the world's first super telephoto lens incorporating a diffractive optical element for camera lenses [1]: the EF 400mm F4 DO IS USM.
In conjunction with the launch in September 2003 of the highly acclaimed EOS Kiss Digital SLR camera, which has achieved outstanding success worldwide with sales to date surpassing 1.2 million units, Canon expanded its EF lens lineup with the introduction of the EF-S series of lenses, optimized for use with digital SLR cameras that incorporate APS-C size (22.2 x 14.8 mm) image sensors.
Canon's current EF lens lineup comprises 60 [2] models, the most comprehensive selection*3 in the industry. Canon EF lenses span the gamut from ultra-wide 14mm to super-telephoto 600mm lenses and include standard and super-telephoto zoom models, large-aperture lenses, and TS-E lenses, which are equipped with a special tilt-shift mechanism that permits the manipulation of image perspective and distortion. Canon EF lenses have garnered high praise from a wide user base, from professional and advanced amateur photographers to novice photo enthusiasts, and earned Canon top share of the interchangeable lens market.
Also, as EF lenses are ideally suited for use with Canon's EOS D-series of digital SLR cameras in addition to its 35mm film SLR cameras, the company aims to continue developing the lineup as the core of the EOS system.

New Lenses for Bronica Cameras presented at PMA '97

New Lenses for Bronica Cameras presented by Tamron at PMA '97

In a significant enhancement of the Bronica camera line, Tamron has added three innovative new lenses incorporating Tamron technology.

The new additions include the world's first medium format camera zoom lens to offer Internal Focusing, the first full-frame fish-eye lens in the Zenzanon P-series, and the first new lens for the Bronica GS-1 camera in 10 years.

For Bronica ETR-Si users, they now have at their disposal a lens that's unique in the medium format category. Developed by Tamron, the new PE100-220mm F/4.8 Aspherical (IF) zoom lens is the world's first medium format camera zoom lens to offer Internal Focusing. The lens also provides the outstanding optical performance of the renowned Zenzanon lenses while incorporating Tamron's state-of-the-art design technologies, such as the use of a Hybrid Aspheric element.

In addition to the Internal Focusing (IF) system, which allows focusing to occur without changing the overall length of the lens, the PE100-200mm features a new "Double-Speed Focus Cam" system developed by Tamron that widens the rotation angle of the focusing ring, making delicate focus adjustments easier. The new lens provides close-focusing with a 1.0 meter M.O.D. (Minimum Object Distance) throughout the zoom range and provides maximum magnification ratio of 1:4.9 at the 220mm setting.

The lens' compact size is also attributable to the use of Tamron's Triple-Cam Zoom and Integrated Focus Cam systems. These advanced technologies are used in this PE Zenzanon zoom lens to insure true zoom capability over the entire focal length range.

In other news for Bronica users, Tamron has introduced the first full-frame fish-eye lenses in the Zenzanon P-series for Bronica medium format cameras. The Zenzanon PE-30mm F/3.5 and PS-35mm F/3.5 full frame fish-eye lenses are for Bronica ETRSi (6x4.5) and SQ-Ai (6x6) medium format cameras. The lenses have a 108° diagonal angle of view and are capable of producing images with exaggerated special effects.

Both lenses have inherited the Zenzanon optical characteristics of high resolution and contrast. Flare and aberrations, especially problematical in fish-eye lenses, are suppressed through the use of an internal lens hood and the application of Tamron's exclusive BBAR (Broad-Band Anti-Reflection) multi-layer coating. The resulting images are high-contrast with sufficient corner illumination and enhanced light transmission for crisp color rendition.

Close-focusing for special effect photography with exaggerated perspective is realized with a minimum object distance of 10.6 inches (0.27 meters) for the PE-30mm lens and 11 inches (0.28 meters) for the PS-35mm lens.

Finally, underscoring its renewed commitment to the popular Bronica GS-1 camera system, Tamron recently introduced the first new lens for the GS-1 camera in 10 years. The new Zenzanon PG-80mm F/3.5 lens was made available this past Fall by Tamron.

This slightly wide-angle lens for the 6x7 format has a 35mm format equivalent focal length of 40mm, with a 58.6° field of view. Its compact size and modest weight allow the lens to be used comfortably in the field for all applications. The F/3.5 maximum aperture lens is as bright as the standard 100mm F/3.5, providing a bright viewfinder image for easy focusing. Like all PG lenses for the GS-1, the apertures are detailed with full and half-click stop detents, and the leaf shutter, a Seiko #0, provides shutter speeds from 1/500 second to T (time exposure), and B (bulb).

The GS-1 is arguably the most versatile SLR medium format camera produced, with the capability of shooting 6x7, 6x6 and 6x4.5cm, as well as Polaroid. Because of this, the new 80mm PG lens has other implications for this system. The GS-1 camera is used by a number of professionals with a 6x6 film back for candid work, as it obviates the need to turn the camera for vertical shots, and it provides an easy square print for a different look in a wedding album. Now, the GS-1 has a "normal" lens for this format, and a "nearly normal" one for 6x4.5cm, increasing an already versatile camera's utility.
