The following equation works for compensation in f-stops: Compensation=(bellows extension/focal length)*Log2

I use an emulator for an HP programmable calculator on my cellphone, so it was pretty...

A used lens, as they aren’t being made new anymore.
Shutter condition is by far the most important aspect to consider. If the shutter that comes with the lens is not damaged or obviously faulty,...

With all due respect, you aren't getting half answers. Because you don't understand the answers you have received does not mean people are misleading you.

You need a Series VI adapter that has a...

15/32 is likely 1 15/32 inches. You need a series VI adapter that matches the outer diameter of your lens. Based on other posts I’m seeing, that’d be 1 1/2” or 38mm

If you have an iPhone, I recommend an app simply called Viewfinder. You can set the film format, focal length, and there’s even a rudimentary light meter (although I would never use it). You can also...

Good question! If you have a spare ground glass the size of the film, you could hold that at the correct distance from the back of the camera (whatever the 3x4 filmholder T-distance is) and see what...

Hopefully less than the going rate for Foma 400 ;)

I believe that Frankenstein is the same as Foma / Arista 200. The box looks identical to the Foma boxes I've seen, and the given development times are very close.

I'd be more inclined to believe the serial number in question is an assembly sequence number.
I have two 7x11 Eastman No.2's and one is stamped 492 on the back side of the rear standard (directly...

The answer depends on the age of the lens. Early 355 G-Clarons are threaded for Compound #3 shutters and won’t directly thread into either Copal 3s’ or MOST Copal 3 shutters. I say MOST Copal 3’s...

Not image circle, but angle of coverage. The image circle depends on focal length, lens design, and magnification / focus distance as well.
Fuji terms the SW series as 'super wide' because of their...

It seems that what you're referring to as field of view is really angle of coverage. The 75mm lens would have a larger field of view given its shorter focal length.

Hard to say. The bellows extension in that photo does not seem very long. Assuming the photo wasn't posed and the camera was actually focused on the landscape, maybe something in the 150mm range?

That looks to be a Phillips Explorer, the design of which inspired the construction of the majority (if not all?) of Chamonix's cameras.

The home page of this very site may have the info you're looking for. ;)
While it is not an exhaustive list of lenses that cover 8x10, it should cover the newer ones:...

I can vouch for the SP-810 as well. I've gotten great results with everything from 4x5 to 8x10 (I haven't tried 7x11 yet - it may be just a hair too long). Quick to rinse and reload, as there's no...

I can't speak to shipping costs to BC, but you can get 8x10 sheet film from online retailers here in the US like B&H and Freestyle Photo.
Unless you're speaking more about film emulsions than actual...

I believe it would fit, but the only way to know for sure would be to unmount the Optar from the lens board and measure the resulting hole. I have a 135mm optar on an anniversary speed graphic, and...

Try sliding the front standard further back into the body once it's horizontal.

When I replaced the beamsplitter glass in my Speed Graphic, I was able to loosen the adhesive from the edges of the glass by gently chiseling at it with a very small flathead screwdriver. The...

I just replaced the bellows on my 45A a few months ago, so the process is pretty fresh in my mind.
I used my set of small screwdrivers, some small/medium-sized binder clips, contact adhesive,...
