Best for
A serious astro-landscape prime - 20mm at f/1.4 is an unusually fast combination, well-suited to night-sky work, aurora, environmental portraits and interiors. Bulbous front element means no screw-in filters. On Nikon Z mirrorless via FTZ/FTZ II adapter, AF is preserved.
Frequently asked questions
Can I use front filters with this lens?
No - the bulbous front element makes a screw-in filter impossible. Specialist 150mm-class filter holders are the workaround.
Is this good for astrophotography?
Yes - f/1.4 at 20mm on full-frame is exceptional for night-sky work, with the Art line's coatings controlling coma and flare well.
Does this lens have image stabilisation?
No — this lens does not have image stabilisation.
