Re: Lens Focal Length vs S.U.8 (pro)

Images attached showing...

1. Initial SU screen view set up with SU 50mm lens
2. SU screen view after opening Twilight, clicking on camera tab and changing lens to 50mm

In 2. the VCB still shows 50mm but if you click Zoom in SU the VCB changes to 72mm.

Hope that helps.

Lens Focal Length vs S.U.8 (pro)

I've just set up a view in SU and set the F.O.V to 50mm. Twilight shows the Lens Focal Length (mm) as 34.722mm. If I change Twilight to 50mm the image in S.U. expands off screen and S.U. reports the focal length as 72mm! Is this a bug as the differnece in the renderings is a very slight change in sh...
