Air Ministry 36inch f6.3 lens

The shutter issue is problematic I have just used this lens with wet plate and paper negs My improvised shutter is a top hat but a lens cap would suffice. I follow a rule of two second exposures So with paper negs in the sun Im having to step it down to achieve the 2 second expo.

Maybe in front of a 7x5 Graflex, or find a 10x8 focal plane shutter they were made by Thornton Pickard. I have 2 half plate FP shutters one goes to 1/1000, but the slit width is fixed and narrow so it's going to be hard to use

Essentially what you've made was what I saw at the camera fair but with a 5x4 reflex camera on the end, and of course it's effectively longer on 5x4 rather than 10x8.

Bet on the 5x4 format its a horror for those hand held shots

My assistant will help drag it he's very strong

It's interesting shooting subjects like this with LF and telephotos, I have the advantage of living 5 mins walk . . . . and knowing the best vantage points as well further up the line. A 36" lens looking down on Arley Bridge (used for the Robert Powell version of 39 Steps were he hangs under the bridge) would be easy and amazing.

Sounds a most delightful spot you have in mind Though the assistant will need the strength for no three legged tripod will support it

No problem he has four legs

More seriously the size (but not the length) could be more manageable and smaller if shooting just g 5x4, the big Bertha cricket camera I saw was smaller. People buy old Speed Graphics and just use part of the case and the FP shutter, sometimes using the shutter behind or in front of a lens so they can shoot a much larger formats. THat may give you food for thought.

It is food for thought as taking this out is a mission and a halve Perhaps one day I make her abit smaller Though its tempting to also go larger as her image circle is most generous

Re coverage, the lens was made for cameras that shot 9" x 9" on 10" roll film. It has to cover ~ 325 mm.

That would be at infinity and perhaps double at head shot distance?

Just for the record.
