What a whopper!

I always loved this picture!

I wish it were larger.

The 132.9 F2 B&L Super Cinephor weighs 520 grams.

Thanks Daniel, added.

R. Knoll f5.5/360 Doppel-Rigonar. Not nearly as big as some but my largest lens. I recently finished machining the mounting flange and have it mounted to a 6x6 board.

Nice.

My daughter now off to college with the Dallmeyer 8D that I use for my 20 x 24 wetplate work

Wow. That certainly is a whopper I wonder what happened to the lens in this Dallmeyer 8D thread?

I've been using this 305mm Metrogon since 2010 on my 8x20. It weighs 6# without the red/yellow graduated center filter(s). I haven't seen a 305mm offered for sale in many years. The 75mm and 150mm versions are pretty common. The 305 fits on a 6" lensboard. To accommodate the weight I incorporated a strut to support the aged components of the Kodak 2D I converted to 8x20. Waterhouse stops are the only way the apeture can be controlled. There is no room between the lens cells to fit anything in there. I use an 8x10 darkslide as a shutter. The product sheet has most of the info you were looking for. The small view camera lens (for size comparison) is a 135mm Schnieder on a 4x5 Wista lensboard.

Do you fit the darkslide between the center elements as possibly Waterhouse stop and sliding shutter?

There is enough room for Waterhouse stop between the cells.
The darkslide shutter goes over the front element. The attached photo shows an identical application with a different lens and 4x5 darkslide. I don't have a photo of my darkslide shutter on the Metrogon, but the design is the same as the photo but using an 8x10 darkslide.

There is the possibility of a shutter between Metrogon middle cells. I had one on 8x10. Sorry I don't have more pictures but here is one. It fit. One fixed aperture but that was to maintain optimal resolution at infinity, a rule for certifying mapping lenses during its time.



I have another of similar design, but more complicated for very high shutter speeds.

Very smart. Simple, ergonomic.

For those 'on the other side of the pond' who might have missed it, how about this?
