Re: Progress on the incognito case

[Daniel J. Matyola]

I've never driven a train, but I had an experience that came close.

On one of our trips to Switzerland, we took the Glacier Express to Zermatt
and then local trains to Montreux.  My travel agent friend had connections
with German Rail, and booked me on the Crystal Panoramic Express from
Montreux.  The trains on this route are special trains with bigger windows
that are almost completely transparent so one does not miss any scenery.

https://www.trip.com/blog/there-is-a-journey-called-the-panoramic-train-journey/
https://en.wikipedia.org/wiki/GoldenPass_Line

Our tickets had the car and seat numbers on them;  I found what I thought
was the right car, but there were no seats to match our tickets.
Eventually, the conductor looked at our tickets and opened the front of the
car, which I had assumed was the engineer's compartment, where there were
four seats in the absolute front of the train, with nothing but glass
ahead, to the sides, and overhead.  (The engine was in the rear of the
train.

There we sat, mesmerized, as the train zig-zagged up the mountains, with
views of Lac leman, Mont Blanc, the Alps, the Jura, and one quaint Swiss
ski resort after another.  There is no rail to compare with Swiss Rail, not
even the Rocky Mountaineer.

I once recited (a version of) that poem to a friend, but as it turned out it 
was his job to drive the train.  He has even taken me for rides in the 
locomotive on a couple of occasions.  It was very fun.

It's not my job to drive the train,
The whistle I can't blow.
It's not my job to say how far
The train's supposed to go.
I'm not allowed to pull the brake,
Or even ring the bell.
But let the damn thing jump the track
And see who catches hell!

Re: Progress on the incognito case

[Larry Colen]

On the subject of going full engineering nerd, my brain keeps coming back to 
how to make one of these as a “real product”. I really ought to be wasting my 
time in a more productive manner.  Some of y’all might be amused by the thought 
experiment.

I’ve been doing more tweaking on the design ideas.The Pentax 645 mount has 
a diameter of about 61mm.  That means that you could make plates with p645 
mounting flanges, then make Pentax K-mount back caps that have 645 lens side 
flanges on them that would lock into the plates.  You could also make back caps 
that fit other lens mounts, Nikon etc. that also mounted into the plates.

I’m beginning to realize that you would want the mounting plates to be of 
different sizes and hole spacing depending on the diameter of the lenses and 
sunshades.  Probably half inch increments from 2.5”-4.5”.  You might also want 
some sort of way of elevating the lenses, maybe the equivalent of extension 
tubes, maybe something that is just a storage area under the squares (store 
filters?). There would also be a need for spacer plates to make up the 
difference when having mounting plates of different sizes adjacent to each 
other.  

It would ultimately also need ways of holding lenses on their sides, and 
ideally ways of making them pretty much drop ins for pelican cases.

Ive made progress on my incognito lens case. Im not completely 
thrilled with the layout but it seems to be pretty close to workable. Id 
like to improve the mounting of the tray for the small primes so there is more 
functional storage underneath it.

https://photos.app.goo.gl/4xx9sQvo2FUeL6kNA

I should figure out how to make dividers, and maybe put some soft foam on the 
underside of the lid to help keep things in place.

What Id really like to do is 3-d print back caps that had tabs on the 
outside, and basically make bayonet mounts for them, so that I could latch them 
into the hard case, but when I wanted to put them in a smaller camera bag, 
Id take out the lens, back cap and all, and just go with that.

The famous, largely unschooled, English Canal Engineer, James Brindley, 
designed his canal systems mentally while sitting in a darkened room. 
His famous Bridgewater Canal featured aqueducts over rivers which 
ultimately ended the monopoly of the river boat transporters in the 
Birmingham area. Then came the railways which put paid to the narrowboat 
traders but the canals live on for recreational purposes!

That’s an idea, though if I were doing that I could glue a body cap to the back 
side of the back cap, and that way I could latch the lenses in with either the 
custom cap, or directly without the custom cap.

It turns out that 3-d printing isn’t too expensive if you have a friend that 
can do it for you.

Re: Progress on the incognito case

How about this...use a bayonet body cap mounted bayonet up in the case 
and use a double rear lens cap on the lens.  Lens fits into one side of 
the double cap and the other side captures the bayonet body cap.  Will 
probably cost about $20/lens but might be cheaper and certainly more 
available than something 3D printed.
