Marc Alhadeff from Sonyalphablog tested the new Tamron 11-20mm f/2.8 E lens:
The Tamron 11-20mm F2.8 Di III-A RXD (900 euros) is an exceptional zoom lens for APSC. It provide excellent results at all focal lengths with very nice bokeh, background blur, color rendition , AF, low distortion (except at 11mm) ….The only minus is the resistance to flare.
It will be ideal for landscape and architecture photography but also for video use, Vlog on the ZV-E10, gimbal usage
It is way above the Sony E 10-18mm F4 OSS and doing as good in the centre as the best APSC Prime for Sony Emount in the focal range.
A must have for Sony APSC bodies !
