Re: Worm gear reducer

The lens is nikkor 18-105 at a little bit more than 35mm. 1/30 sec, iso 400, f13, monochrome preset with sharpness set to +6, 1080p 30 frames/sec, all enhacers like d-lightning, denoise etc. shut off, wb set to flash preset. Now I can not show you the live scene 'cause the scanning is already done.

I use Nikon via blackmagic shuttle usb3.0.
