Sigma Lente 18-50mm f/2.8 EX DC Macro para Olympus (Sistema de 4/3)
- No Longer Available
A popular lente Sigma 18-50mm f/2.8 EX DC Macro foi aperfeiçoada com recursos de focagem mais próxima ¿ proximidade até 7,9 polegadas (20cm) - e possui uma taxa de ampliação máxima de 1:3, ideal para fotografia close-up. Esta lente foi projetada exclusivamente para atender as características das câmeras digitais SLR. As características das câmeras digitais SLR foram levadas em conta durante a criação do layout de potência de lente. O avançado design da lente corrige diversas aberrações. Esta lente oferece a mais moderna correção de aberração cromática lateral, que é um sério problema para câmeras digitais SLR.
Esta lente também é revestida especialmente para obter o melhor balanço de cor com uma câmera digital, reduzindo também os reflexos e fantasmas causados por reflexos do sensor de imagem digital e da lente. Oferece correção para vinhetas, além de garantir um brilho periférico superior. Ideal como uma lente zoom padrão de qualidade com capacidade macro incluída, essa lente oferece uma faixa equivalente de aproximadamente 36-100mm quando utilizada com uma câmera digital SLR da Olympus (*).
Lentes DC foram exclusivamente projetadas para câmeras digitais SLR. O círculo de imagem (parte de trás da lente) é projetado para combinar com as menores dimensões usadas para o sensor de imagem das câmeras digitais. O resultado é que essas lentes também são mais compactas e leves, e são mais adequadas às câmeras digitais SLR.

Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
Good general purpose lens. A little darker than a fixed lens, but a small price to pay for the flexible zoom range. I'm very happy with the macro clarity. Solid build and good bang for your buck. I use this lens for everything now.

Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
I have only used the lens for a couple of weeks but I have been impressed so far. The macro shots are vivid and clear with no distortions. I used the lens for a group of family shots and they turned out very well. I also took the camera on a trip to Mackinac Island with our Boy Scout troop and received great shots. The lens is very quiet, much quieter than the lens that came with my olympus kit.

Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
This is a great lens. the f2,8 over the full range is wat I like most about it. Very sharp and fine color match. One thing that aren't so good is the AF-motor. It's quite loud and sometimes it scares animals away...

Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
This is a great lens for nature photography. Floral photos and the inscets on them are easily captured with this lens. Using a 2x teleconverter this is also a very good lens for wildlife photos.

Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
This lens is very quick and sharp. I use it as my general all purpose lens, and for indoor sports and am amazed at the pictures i get. I was a little unsure on it at first because i have never owned a sigma before but after reading reviews bought it and love it. For an all purpose lens it doesnt get much better.

Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
Excellent glass. I use this lens for general portrait/wedding photography. Also for macro work of wedding details. The manual focus ring is a little loose, but the zoom ring is good and tight. Very fast lens, good for on the fly photojournalism style photography that I use. Slightly heavy, but has a superb feel overall to it. I also keep it on as an all around lens. Price a little high compared to what is made for other brands, but, as 4/3 gains popularity, price will come down. I use and E-500 and E-510, both from B&H, with another Sigma lens, the 30mm f/1.4, another great choice for discerning photographers of any skill level.

Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
Bought this for an olympus e510 body. Impressed with the build quality and love the pictures it takes.
Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
...in spite of its constant maximum aperture. What elsecould you ask for? Weather-sealing? So far I haven't neededit with either my E-510 or my brand new E-3.It's become my walk around lens. With the E-3 it snaps intofocus immediately. It is the ideal combination for indoorsas well as for landscape photography.

Comments about Sigma 18-50mm f/2.8 EX DC Macro Lens for Olympus (4/3 System):
I bought this lens instead of the Zuiko 14-54, because I wanted the constant F2.8, and the macro part was just a bonus.I have been nothing but happy with this lens after 6 months. I would recommend to anyone.

Clear glass. Works great with the Evolt-500. Love the manualfocus ring. Much faster than the floating manual focustypes. Great build quality. Heavy, but feels good.
