I often shoot at f/4 though for a little more smoothness in the bokeh and a bit more sharpness.

Thanks for the info on your setup and the cross bar and such - that looks like an interesting piece of the puzzle. I don't have that on mine, and haven't seen it on others before.

Custom cams seem fairly common for users of these cameras I think. I recently made one for myself, using 2mm aluminum and making it with various hand tools. It's not the prettiest but it does work well. The precision needed on these is fairly tight, basically all surfaces (edges) of the cam come into play at some point on it's usage, not just the inner slots.

For my 150 custom cam pictured, I wanted a closer close-focus distance than the stock cam. Basically I just traced out the stock one and then extended the length of it a fair bit more. After some adjustments, it's working fine, quite smooth in operation.

Mine is aluminum but I think the stock ones are made out of chromed brass.

Hello Cambo TWR owners and connoisseurs

I have recently become the happy owner of a Cambo TWR. I'm thinking of making copies of the
2 cams I have (150 + 210 mm) and, like EdSawyer, providing them with extended extension for close-ups. Am I right in assuming that the parallax correction is no longer given? Has anyone investigated this or measured how big the deviation is?

Another question:
Has anyone tried 3D printing instead of making the cams in metal?
