Sigma EX DC HSM 4.5mm f/2.8 5mm
The fast f/2.8 aperture and 180-degree circular projection on APS-C sensors make this a specialized tool for low-light scenarios like astrophotography. Its equisolid angle projection method provides quantifiable data for scientific use, while the HSM motor enables quiet autofocus with full-time manual override. This lens is best for aurora photographers and researchers needing precise solid angle measurements of sky or vegetation distribution.
