New Sigma 4.5mm lens for DSLR's
Just found out that Sigma are launching a 4.5mm lens for Canon and Nikon DSLR's with the APS-C sized image sensors.... (eg the Canon 400D)
Looks like it's going to be a fun lens which will deliver some quite stunning results... Not to everyones tastes - but it's something that interests me...
Sigma are actually launching two wide lenses - this press release covers the 4.5mm - but there's another one coming as well... I don't have my copy of Amateur Photographer handy at the time I'm writing this - it's in the boot of my car - but there's detail in there of another Sigma lens about to come to market.... It's a 10mm...
From the Sigma press release on the 4.5mm:
4.5mm F2.8 EX DC CIRCULAR FISHEYE HSM
The first 180 degree circular fisheye lens designed specifically for APS-C size digital SLR cameras
Fast F2.8 maximum aperture making it ideal for low light photography
Minimum focusing distance of 13.5cm and a maximum magnification of 1:6
SLD glass minimizes color aberration
Equipped with HSM with full-time manual focus override
Equisolid angle projection method is possible for art and scientific use
The Sigma Corporation is pleased to announce the launch of the new 4.5mm F2.8 EX DC CIRCULAR FISHEYE HSM lens.
This autofocus circular fisheye lens has an angle of view of 180 degrees in all directions. It is exclusively designed for digital SLR cameras with the APS-C size image sensor. When used in conjunction with digital SLRs with APS-C size image sensors, it produces circular image within the frame.
The F2.8 large aperture value produces a bright image in the viewfinder and allows photographers to take pictures in low light conditions, making it an ideal lens for Astrophotography and Aurora photography. Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific and arts applications such as solid angle measurements of cloud distribution over the sky or vegetation distribution of the forest.
The minimum focusing distance of 13.5cm/5.3inch and maximum magnification of 1:6 make it particularly useful for close-up photography. SLD(Special Low Dispersion)glass provides effective compensation of chromatic aberration. Sigma’s Super Multi-Layer Coating minimizes flare and ghosting. It is equipped with an inner focusing system that creates high definition and good image quality over the whole frame. The HSM (Hyper Sonic Motor)ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring.

At the moment they're around £450 for the 10mm and £600 for the 4.5mm....
