The Sigma 8mm f/3.5 EX DG is a spherical fisheye lens that easily captures a full 180° view in all directions, in a circular image. Even the most familiar and mundane of subjects can be portrayed with startlingly fresh new expressions through exaggerated perspectives and unusual distortion effects.

Well suited for academic and technical measurements such as solid angle measurements, cloud cover measurements & virtual reality.

Note: Full circle can only be captured with 35mm format digital SLR and film SLR cameras.

Improvements
This improved version offers a brighter f/3.5 aperture, with a vastly improved minimum focusing distance of 5.3" (13.5 cm) and a maximum magnification of 1:4.6.
Circular Image
This circular fisheye lens can be used to create circular images with an angle of view of 180°. It permits creative expression through the exaggerated perspectives and unusual distortion effects.
DG Design

This lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.
Equipped with AF
This extreme fisheye lens is unique as it incorporates an auto focus system to get accurate focusing that might be difficult through finder due to extremely large depth of field.
Ideal for Scientific Applications
This lens is useful for academic/technical applications such as solid angle measurements, because it provides a quantifiable angle/area relationship. It is widely used in science and industry for cloud cover measurements, weather observation, astronomical studies, agriculture etc.
Gelatin Filter Holder
The lens is supplied with an insertion-type gelatin filter holder at the rear allowing the use gelatin filter.

    I would have kept the lens if I only knew that the lens cap attachment sleeve is removable!I put it on my full-frame sensor DSLR, expecting the image circle to nearly completely fill the vertical height of the frame, but it measured only 19 mm, which wasted a lot of space (and resolution). I also noticed that it was definitely not a full 180-degree angle of view, which was critical to me. There was also a lot of flare caused by the rings where the lens cap attaches.This was all very disappointing and I returned the lens to B&H [...]As it turns out, all three of these problems were the result of me leaving a sleeve on the lens that is used to attach the lens hood. This piece appeared to be an integral part of the lens, like a built-in lens hood, and it simply never occurred to me that it was removable! I wasn't being stupid; my other wide-angle lenses both have built-in lens hoods, and I somehow assumed that this one did too.The lens was otherwise perfect and I did snap a few pictures with it before deciding to return it, and it produced extremely sharp images at f/8 on a tripod with no chromatic aberration. If you plan to defish the image through software, you can expect good results. The only problem I noticed is that the distance scale ring is off by quite a bit, and shows 1 metre when actually focused to infinity. This is the only reason that I'm giving it 4 stars instead of 5. It doesn't mean that the lens misfocuses. Autofocus was quick and accurate.If you need a 180-degree image circle with high-quality results, then I recommend buying this lens, just know that you have to REMOVE THE LENS CAP ATTACHMENT SLEEVE before using it!

    Using this lens for only the purpose of stitching images together for panoramas. Works well, but I have not put it through much else. Crisp images.Cannot use a filter externally, only filter that can be used is to cut a gel to proper size for internal slot. Lens can trap dust at edge of glass because body stands slightly proud of glass, but this also gives glass better protection.

        Webought this lens to shoot Google Business Views panos as our secondary gear. At first use, we found that it has very little flares, which helps with our current use of it.
        It´s not as versatile as other fisheyes we own, but it is very robust and simple to use.

              Comments about Sigma 8mm f/3.5 EX DG Circular Fisheye Autofocus Lens for Canon EOS:

              On a full-frame camera this lens provides a circular image with all the distortion expected for a fisheye. The circular image will not fill the frame or reach the edges of the frame. The circular image can be cropped and "unfished" with the adaptive wide angle filter in photoshop. If you just want to get a super wide angle lens, the distorion might be a bit extreme with a fisheye. In this case the Canon 8-15 might be a better, though more expensive choice, as it allows a full frame image at 15 mm and a circular image at 8 mm with increasing distortion at intermediate settings. This Sigma lens has a detachable holder for the lens cap, filters or hoods, but virtually all including the holder will vignette the 180 degree image--forget it, slide off the holder before using.

                                      Using this lens for only the purpose of stitching images together for panoramas. Works well, but I have not put it through much else. Crisp images.Cannot use a filter externally, only filter that can be used is to cut a gel to proper size for internal slot. Lens can trap dust at edge of glass because body stands slightly proud of glass, but this also gives glass better protection.

                                            I primarily use this lens for virtual tours. Unfortunatly I only have the Canon 7D so I don't get the full fisheye effect that a full frame would give.
