Sigma 10mm f/2.8 EX DC HSM Fisheye Lens for Sigma Digital SLR Cameras Review
First off, bear in mind that I purchased this Sigma fisheye to replace Nikon’s 10.5mm f/2.8 fisheye. While I was happy with the Nikon’s optical performance, I was disappointed with the AF design. Nikon’s lens relies on the AF motor in the camera, which makes for noisy AF. In addition, this design precludes full-time manual focus touch-up. And finally, the lack of an in-lens focus motor precludes AF on the existing D40/D40x and new D60, as well as future Nikon DSLRs lacking an in-camera focus motor.
In any event, when Sigma announced their fisheye lens a few months ago, I decided that I would purchase one. And I am very happy with it! The HSM provides autofocus performance as fast as the Nikon (at least on my Nikon D300 DSLR), while being eerily quiet.
As for the optical quality, it appears to be virtually identical to Nikon’s, which is to say excellent. Both lenses are slightly soft wide-open (i.e. at f/2.8), but sharpen considerably when close down one f-stop. Indeed, both lenses are almost as sharp at f/4 as they are at f/5.6.
Besides the built-in autofocus motor, another difference between Nikon and Sigma’s fisheye lenses is the field-of-view (FOV). Sigma’s lens is 0.5mm wider, and provides a small — but definitely noticeable — increase in the angle of view.
So, it all comes down to this:
* Do you currently own a D40/D40x/D60, or plan to purchase one?
* Do you prefer super-quiet AF to the noisy mechanical variety?
* Do you prefer a better-built lens?
The one advantage that Nikon’s lens has is size/weight. While arguably not as durable and well-built as the Sigma, it is lighter and more compact. If this is important to you, then you may prefer the Nikon. (See the comparison photos I posted to see what I mean.)
As for Cons, there is one. Sigma’s lens is, unfortunately, not weather-sealed. I was hoping that Sigma would at least utilize a gasket around the lens mount, but that is not the case. As such, I recommend against using this lens in rain/drizzle — or in a super-humid environment. (It is important to note that Nikon’s fisheye lens is not weather-sealed either, and also lacks a lens mount gasket.)
Apart from the one aforementioned complaint, I highly recommend the Sigma 10mm fisheye lens. It provides all of the performance/quality of Nikon’s fisheye lens, while providing fast and quiet autofocus to owners of ALL Nikon DSLR’s, including the D40/D40x/D60. You will not be disappointed!

Sigma 10mm f/2.8 EX DC HSM Fisheye Lens for Sigma Digital SLR Cameras Overview
This autofocus fisheye lens is designed for use with digital SLR cameras equipped with APS-C size image sensors. The Nikon version produces a diagonal angle of view of 180� (154�for Sigma, 167� for Canon). The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective and distortion. The minimum focusing distance of 13.5cm/5.3inch, and maximum magnification 1:3.3 allows subjects to be as close as 1.8cm/0.7inch from the lens’ front element. This close focusing capability allows close-up photography and also it is possible to make use of large depth of field that covers wide range of subjects. The Integral hood blocks out extraneous light and the Super Multi-Layer Coating minimizes flare and ghosting, creating superior image quality. The HSM (Hyper Sonic Motor) ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring. This lens is supplied with a gelatin filter holder at the rear, allowing the use of gelatin filters.
