Just a couple of follow-up questions:
        a. What is your base plate material? Does it seem that it will be rigid 
enough?

I forget what it is called, but it is basically corrugated plastic. At first I didn't think it would be, but the prototype has worked very well.

        b. Will you secure the base in your bag in some way?

It seems to fit rather snugly. I had considered velcro.


I am thinking about the situation with four heavy lenses attached, the bag is 
sitting (or being carried) at less than 90° vertical, and the weight of the 
lenses might torque the baseplate out of position...

Good point. In my use case, I just use it for my smaller primes and carry the big lens in the compartment designed for carrying lenses, with dividers and all.


And a design-change thought:
        It might be useful to glue a few velcro strips onto the open areas of 
the base plate. To be used when the occasion calls for a flash unit or other 
accessory that you want to have in the bag without having it rattling around.

Yup, that's where I usually carry my filter wallet. Once the glue has set, I'll get some photos of the whole setup. I'm also thinking about making some plates to go into my Rigid brand carrying cases from Home Depot.

As much for a stable place to hold them at home as an easy way to carry them. It would have the side effect of protecting my gear from minor home catastrophes that involve lots of water.

My fotodiox back caps arrived today. I just made a lens carry plate using them, 
as the other caps I had been using didn't hold my lenses quite as securely as 
I'd like. It actually pretty much worked, and would be fine in a drawer or 
something.

One thing I realized was that I want the bayonet tabs all oriented the same. I marked 
them with a silver sharpie, in this orientation the lens will go on with the red dot 
facing "the bottom of the screen".

I apologize to my non-USAian friends for all of the measurements being in 
inches, but those were the measuring devices that I had handy. The base plate 
is cut for a Fastpak 350 (even though they have been discontinued there are 
still some left at good prices btw). The spacing of the caps is not even 
because my DA*55 has a rather large lens hood. For that matter, so does my DFA 
50 macro.

And, yes, I know, the measurements are very rough, and don't necessarily all 
add up. Making the proper adjustments in the design is left as an exercise for 
the student.
