Build Quality

“Not guaranteed to be 100% dust and moisture proof, but all the seams are sealed, the buttons and switches have silicone rubber gaskets, and there's a rubber ring seal around the lens mount.” — Gerald Undone

“views now it's not the first general purpose zoom lens to reach 20mm at the wide end Panasonic introduced to 20 to 60 kit Zoom almost three years earlier albeit for L Mount bodies only so it's not an option for Sony owners however towards the end of 2022 Tamron launched a 20 to 40 mil for the Sony…” — Gordon Laing

“However with bit of googling it's easy to find authorized dealers currently as of February 2025 offering this lens for around €1300 and in my opinion that's a completely reasonable price.” — Jan Smid, MASTER QEP

Distortion

“So, having a look at the distortion and vignetting now at 20 mm wide open at f4, you can see some pretty heavy barrel distortion as well as some vignetting in the corners.” — Stefan Malloch
Vignetting

“But the vignetting on this lens when you go down to 20 mm is rough.” — Peter Lindgren
Chromatic Aberration
2 pos · 3 neu · 1 neg
“news at F4 very little color fringing on bcka Highlights is visible at all so it's not a real problem overall well can I be honest when I first received the lens I felt a certain cynical curiosity how could it possibly perform well at 20 mm and still make room for the rest of that Zoom range and how” — Christopher Frost

Filter Thread

“72 millimeter filter thread versus the 67 on the old one and a tiny bit heavier of course the new lens use a lot more Posh plastic in its construction the old one is like a metal Barrel which is nice and robust a new one even the thread is plastic but still somehow it feels quite premium I think” — Kai W
