Wow, had no idea the 1635CZ also had so much distortion. I always thought it was a really good lens. Seems like every UWA on he A7 suffers this issue
This is keystone distortion.
Point any WA lens upwards and this is bound to be.
If you want to avoid it, you got to shoot straight w/o pointing up.
Else use a tilt shift lens.
Or use PP
