You can compare the full EOS-R5 and S1H on that special BH comparison tool page. I guess Panasonic has to answer soon with a new S2H camera with 8K video…possibily 60p!

Photographyblog tested the Panasonic 16-35mm lens and concluded:

In its own right, the Panasonic Lumix S 16-35mm F4 PRO lens is well made, handles like a dream and it produces sharp images with minimal distortion. You’ll get decent portraits in the environment with it too.

You get the new Trioplan 100mm lens at BHphoto.

Fotodiox launched the new Canon EF to L-mount autofocus adapter. You can get it at BHphoto.
