Sigma's super multi-layer coating and Special Low Dispersion (SLD) glass provide excellent image quality for digital and film SLR cameras. The special fisheye design allows maximum creative expression.

Love this Lens! I bought this lens for Google Street View photography, and it works like a charm. It takes no time to focus, and gets 4 Inches to Infinity in perfect focus. Being a fisheye lens, it can be used very creatively, though it's main purpose I presume is to create Virtual Media like...

Expensive compared to what is available from china, but good build quality and chip works great with my D7000. Used for doing 360 panos and recognising lens data from PTGUi. Wish chromatic aberrations were a little bit less but I am sure this is as good as the best out there and probably just...

This lens is great, a good addition to my photography toys box, at least for the purpose I bought for, panoramas for Real Estate properties. It has a big flaw though, the auto focus is really sloooooow

bought as part of the google business views program. nice little lens for panoramas and lovely and sharp. This panorama was taken using it: https://www.google.com/maps/views/view/110595744246840784567/gphoto/6062789120376232706

The Sigma 8mm f/3.5 is a very well constructed lens. accidentally, it drop 2 times out of my camera bag from 50cm on a wooden floor and continues to work great.Being a circular fisheye, it shows vignetting on a cropped sensor camera and a full circular image on full frame sensors.

Very wide angle

Real Fun-lens - funky-punky.... optically very strong, sharp, complete circle (not that bullshitcercle from Peleng 8) nearly without flare (forget the cheepo-Pelengo....!). Very good construction, but take care of the frontlens.

Fantastic perspective - 360 = FUN - sharp; nice buildings; very few CA´s; NO FLARE

take care on the frontlens

Adds a flexibility to a wedding photographers kit. Have used successfully with a rayflash ring flash adapter to produce "Jarvie Window" images (look it up) at weddings and parties.
