This lens is STURDY; Very high quality optics; Crisp, clear, and wide every time :D

Price :

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

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...

An updated version of Sigma's 8mm f/4 spherical fisheye, this is the field's widest circular fisheye with autofocus. It's also among the last Sigma film-era lenses to be upgraded with coatings that suppress reflections from digital sensors ("DG").

This circular fisheye lens from Sigma is the world's only 8mm lens with full autofocus capability. With some speciality uses as well as the novelty images it can produce, we take a look at it's capabilities.

High optical resolution; Good control of aberrations; Compact size and weight

Restricted uses (but it is a specialised lens; Expensive if only being used for the fun element

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.
