RF10-20mm f/4L - thoughts?

[keddy]

Advice/Reviews: Who here has / has used the RF10-20mm f/4L? I would love to see some sample images at 10mm. Canon are suggesting the distortion is minimal which I can’t quite wrap my head around. Currently using the lovely Samyang RF14mm f/2.8 AF, which I thoroughly enjoy however it has a pretty significant amount of distortion. The 10-20 f/4L is significantly more $$ so thought I would ask some real people for their thoughts rather than rely on paid reviews online. Thanks in advance!

I've seen some great examples on Canon Rumors, but would love to see some examples here, as I'm also interested in this lens.

There is no comparison between a Samyang and a Canon lens. The Canon although it is a zoom and the Samyang is a prime, the Canon wins hands down every time. IMHO, of course as always. There is more to a lens tan just IQ.
