Sigma 10mm f/2.8 EX DC HSM Diagonal Fisheye
For extreme wide-angle shots, this lens is a great second-hand buy
Released (year): 2008 Price new: £600/$900 Price used: From £200/$250
Like other ‘diagonal’ fisheye lenses (sometimes confusingly referred to as ‘full-frame’ fisheyes), this lens produces an image circle that covers the whole of the camera’s image sensor. In this case, it’s for a DX sensor. Whereas circular fisheyes give a 180-degree viewing angle on both the horizontal and vertical planes, diagonal ones give a narrower viewing angle of 180 degrees on the diagonal of the frame. Even so, that still gives stupendous wide-angle coverage.
This Sigma is fairly compact and lightweight, and delivers very good image quality. The extremely short 13.5cm closest focusing distance and enormous depth of field make it great for funky close-ups (see page 42). The lens comes with a built-in ‘hypersonic’ autofocus system, compatible with your D5200, and a built-in lens hood that helps protect the bulbous front element. As with any fisheye lens, you can’t screw filters onto the front, but a gelatin filter holder is built into the rear of the lens.
