I have a lens to add to the list:

Petzval,No 2482, incl "cup" with one washer stop screwed onto it.

I measure focal length to be 187mm and image circle 205mm at infinity. This likely makes it...

I'm not sure if you're interested in a serial number that falls in the middle of your range. But here goes:

Aplanat B No 4 10x8- serial number is 4468. "Allen Bros. sole agents."

I used a screwdriver in the slot and got an extra quarter turn of tightening. That made a big difference - no movement so far. Thanks for the suggestion.

Even more great advice. Thanks for all the suggestions. Now I definitely don't feel alone!

I think my first solution will be to add some material between the plate and camera (latex perhaps?) and...

Thanks for all the responses. At least I don't feel alone now!

I'll take a look at the Manfrotto plates.

I had thought about screws - but didn't want to mess up the base of my camera (even...

I have a B&J Commercial 8x10 that I am using on a Bogen 3050 tripod with a 3047 head. I have a problem with the camera moving when I am inserting or removing the plate holder. I try to tighten the...

Your first equation is fine. Another way to look at it is to say that the images look like they're around 4x life size on the negatives. That is 1:4 macro. That means the image is going to be 5 x...

Sure it's obvious. They shoot an 8x10 interneg of the original and then scan and print that.

Right??

If I wanted to make a lens shade I would start by making a cone that had the same angle at the apex as the angle of coverage of the lens. A quick search suggests that this is 72 degrees for the...

If you can mount your 210 lens on the 8x10 camera, it will cover that format at 1:1 and larger magnifications. The image circle gets bigger as you focus closer. You'd then need less than half the...

I have been making stitched photos using digital on and off. You certainly can stitch to create a rectilinear image, the same as, say, a 165 SA on 8x10. I do this routinely. The problem for me isn't...

I think it's worse than that. Judging by the examples in the video the images seem to be roughly 4x life size. That means the exposure would need to be multiplied by 25. With your example the...

Out of curiosity I ran some numbers on the depth of field for this camera.

Given the size of image and subject placement I come up with a depth of field of around 8 inches at f/32. That seems...
