sigma apo 135-400 mm

On the site of Japanese company sigma appeared the information about two long-awaited telephoto lenses. Long-awaited, therefore as about their fast release it was known still during November 2005, but are only now promulgated the periods of the beginning of sales, price and precise specifications.
For well-off telephoto is proposed the apochromatic telephoto lens sigma APO 135-400 mm f/4,5-5,6 DEG. For obtaining the high optical characteristics in entire range of focal lengths and reducing to the minimum of chromatic aberration in the optical diagram of objective are used one aspherical lens even three elements of the low-dispersion glass (SLD, Special low dispersion). Application of the new multilayer clarifying coating to called decrease the appearance of specks of light and moire, and also to attain natural color reproduction.

In sale lens will enter on 16 March on the price of approximately 700 dollars.

Technical characteristics Of sigma APO 135-400 mm f/4,5-5,6 DEG:

Focal length: 135 - 400 mm
Minimum diaphragm: f/32
Construction: 13 elements in 11 groups
Viewing angle: 18,2Â° - 6,2Â°
Quantity of lobes diaphragm: 9
Minimum focusing distance : 200 - 220 cm

Maximum increase: 1:5,3
Diameter under light filter: 77 mm
Sizes: diameter - 88,5 mm, length - 183,6 mm
Weight: 1245
Versions: Sigma AF, Canon EF, Nikon AF, Pentax AF, Sony AF

But here the second new product - the telephoto lens sigma APO 300-800 mm f/5,6 DEG HSM. This by an order more expensive monster is characterized by a constant candlepower f/5,6 in entire range of focal lengths and the presence of ultrasonic HSM- motor (Hyper sonic motor), which ensures noiseless and rapid focusing. In the optical diagram of objective are included two elements from the glass (ELD, Extraordinary low dispersion) for the minimization of chromatic aberrations.

In combination with teles-converter sigma 1,4x EX DEG APO either 2x EX DEG APO (they are supplied separately), user will be able to obtain the ranges of focal lengths 420 - 1120 mm with f/8 or 600 - 1600 mm with f/of 11.

Sales super-tele-Vicat sigma APO 300-800 mm f/5,6 DEG HSM also will begin on 16 March. Tentative cost - 7200 dollars.

Technical characteristics Of sigma APO 300-800 mm f/5,6 DEG HSM:
