Tilting Zoerk Multi-focus System Example

Discussing this unit in the Marketplace and found a photo that shows the tilt effect really strongly. Since tilt-capable lenses are a common topic here, thought I'd show the effect.

One of the benefits of tilt is that you can obtain focus on subjects that are different distances from the lens without stopping down. This increases shutter speed range and allows for photos in windy conditions. Basically you can have action stopping capability at the same time as deep focus from near to far.

Note that the depth of field based on f stop is not that deep--see how quickly the focus falls off underneath the bloom or beneath any sharp spot in the photo? Yet, by tilting the lens (and thus the plane of focus) you can get sharp focus on subjects that aren't the same distance away.

This was shot through a 67II on film, but works in a similar manner adapted onto my K5. This particular Zoerk Multi-Focus Unit has a Rodagon APO 105mm enlarger lens. It can work with a couple other Rodagons as well.

Is anyone playing with the new Schneiders?
