large format camera lenses - Schneider 150mm

The Apo-Symmar-"L" series of lenses replaces the well-proven original Apo-Symmar. As some glass types have been phased out for environmental reasons, newer designs with substitute formations were necessary. Seizing the opportunity, Schneider-Kreuznach has now completely re-designed this successful, all-purpose lens to bring it up to the current state-of-the-art of lens design and fabrication. The covering power has been expanded in nearly all cases and the imaging performance further optimized. The current focal lengths and the principle technical specifications are shown in the table below. Used according to the maximum photo format, the focal lengths between 120 and 480 mm offered by the "L-Series" deliver normal perspective pictures without wide angle or telephoto effects.

Instant film.

This image is part of a 15 hour photo outing, which included a trip to the phsc.ca outdoor camera market, feeding Matt some espresso with beer chasers to keep him awake, a trip to High Park, and then a couple of hours around Yonge and Dundas. I should mention that we carried around 2 large format 4x5 cameras, a Bronica SQ-A with a few lenses, a modded Infrared D50, and a 35mm Pentax. The temperature was 35 degrees Celsius. Great times.

Update: Replaced the 405 Instant film holder. Feeling better now.

large format lens on a 35mm SLR

This has nothing to do with my other projects (scanner camera) but yesterday I was playing around with some lenses and I tried to mount a large format enlarger lens on a 35mm reflex using a macro bellows and some adapters, and this is the result.
It can focus from infinite to about 30cm (1ft.) and with some other tweaks maybe it's possible to tilt/shift the lens.
I wish I had a digital SLR to test the resolution... :(
