A Lente HSM 4.5mm f/2.8 EX DC da Sigma é uma lente olho de peixe esférica que captura com facilidade uma visão total de 180° em todas as direções, em uma imagem circular. Até mesmo assuntos familiares e mundanos podem ser retratados com expressões novas através de perspectivas exageradas e efeitos de distorção incomuns. Ela é adequada para medidas técnicas e acadêmicas, como medidas de ângulo sólido, medições em "cloud cover" e realidade virtual.

Ter o HSM (Hyper Sonic Motor) incorporado na lente permite uma focagem mais silenciosa e mais responsiva. Além disso, o recurso HSM oferece a essa lente a capacidade de foco automático com todas as câmeras DSLR da Nikon (incluindo a D40 e a D40x). Esta lente oferece a faixa focal equivalente de aproximadamente 6.75mm quando utilizada com uma câmera digital SLR da Nikon (*).

Lentes DC foram exclusivamente projetadas para câmeras digitais SLR. O círculo de imagem (parte traseira 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, além de mais adequadas às câmeras digitais SLR.

A série EX de lente oferece excelência em engenharia e tecnologia nova.
O revestimento SML (Super Multi Camadas) reduz os fantasmas e os reflexos
O Vidro SLD (Special Low Dispersion) fornece compensação efetiva de aberração cromática.
O HSM (Hyper Sonic Motor) assegura uma focagem automática rápida e silenciosa. Além disso, ele permite a troca para foco manual a qualquer momento através da rotação do anel de foco.

      Comments about Sigma 4.5mm f/2.8 EX DC HSM Lens for Nikon Digital SLR:

      I'm using it in a research project on daylighting architectural space. The circular fisheye allows you to analyze the entire space in a glance...and it works seamlessly with my Nikon D5000. No down side.

        Comments about Sigma 4.5mm f/2.8 EX DC HSM Lens for Nikon Digital SLR:

        I purchased this lens to match a full-frame circular fisheye on a Nikon D300. This lens fits the bill.

        The images are stunning and sharp. This is the only circular fisheye for less than a full frame sensor, but that is not the only reason to recommend it. It is a well made lens that delivers great results.

        If you like fisheye photography and do not have a full frame camera, get this lens

          Comments about Sigma 4.5mm f/2.8 EX DC HSM Lens for Nikon Digital SLR:

          Sharp and light, but very expensive and too long (physically). The circle image is too small for the Nikon 1.4 magnification ratio as the lens was made for other models with a 1.6X ratio

            Comments about Sigma 4.5mm f/2.8 EX DC HSM Lens for Nikon Digital SLR:

            I get a full 360 degree pano with only three photos placed on a rotating pan head. Because it is a full 180 degrees using a DX type camera, you do not need shoot multiple rows with a QTVR head, thus saving you money. The picture quality is excellent. They have outdone themselves on this one.
