Sigma 20mm f/1.4 DG HSM ART lens assessment

- Advertisement -

Quick lenses, just like the Sigma 20mm f/1.4 DG HSM ART lens, aren’t all the time low cost. And low cost lenses aren’t all the time good. The paradox is that astrophotography generally is a spendy recreation – it’s not simply the digital camera gear you want, it’s the star monitoring accoutrements as nicely, which suggests each penny counts in relation to lenses.

Key Specs:

Sort: 20mm prime lens for full-frame and APS-C sensor cameras.
Compatibility: Out there mounts: Canon EF, Nikon F-mount, Sony E-mount, Sigma SA-mount.
Focal vary: 20mm fastened focal size.
Aperture vary: f/2.8-f/16 fixed.
Thread measurement: No filter thread.
Weight: 1kg

Drawback is, an affordable lens goes to inform in relation to star images, wide-field or in any other case. Distortion, comatic aberration, purple fringing – should you penny-pinch on optics you would be setting your self up for long-term disappointment.
