Sigma 4.5mm f/2.8 overview

  • 1Description

Offering creative distortion and exaggerated perspectives, the Nikon F-mount 4.5mm f/2.8 EX DC HSM Circular Fisheye Lens from Sigma produces a circular image with an expansive 180° angle of view. Benefitting the unique look of the lens is an advanced optical design that utilizes one SLD glass element to reduce color fringing and chromatic aberrations for improved clarity, as well as a Super Multi Coating to suppress lens flare and ghosting. Additionally, the lens also features a Hyper Sonic Motor for quick and accurate autofocus performance for working with subjects as close as 5.3" away.

Unique 4.5mm f/2.8 circular fisheye lens is designed for DX-format Nikon F-mount DSLRs where it provides a 6.75mm equivalent focal length.
Expansive 180° angle of view pairs with the fisheye design to render circular imagery within a black frame. This design also renders scenes with exaggerated distortion and curved lines for a creative, true "fisheye" aesthetic.
One SLD glass element is featured in the optical design to reduce chromatic aberrations and color fringing for improved clarity and color accuracy.
Super Multi Coating has been applied to individual elements to suppress flare and ghosting for improved contrast and color when working in strong lighting conditions.
Hyper Sonic Motor autofocus system, and an internal focus design, offer fast, precise focusing performance for working with subjects as close as 5.3" away.
Rear slot accepts cut, insertion-type gelatin filters.

    Sigma 4.5mm f/2.8 reviews

    4.5mm f/2.8 EX DC HSM Circular Fisheye Lens for Nikon F is rated 4.7 out of 5 by 7.
    Rated 5 out of 5 by from What fun! 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

    Rated 5 out of 5 by from Makes shooting panos a snap 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.

    Rated 5 out of 5 by from A fun lens This is a grat lens that you can have a lot of fun with and be very creative. Crop the image and it get's even better. Excellent quality. Nice to see a circular fisheye for less tahn full frame camera's.

    Rated 4 out of 5 by from Beautifully made, sharp and lightweight 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

    Rated 5 out of 5 by from Oooo! This is so cool! 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.

    Rated 4 out of 5 by from Not your everyday lens, but lots of fun I'm delighted with many of my photos taken with this lens. It is difficult to pre-visualize the results, but the effects can be great.
