If you are out in the marketplace trying to sell a product, it is generally best not to insult your potential customers, i.e., photographers who are concerned about maximizing image sharpness and those that shoot verticals.a two part design, the L-plate bolted to the base. to get more port access, slide the entire unit over by loosening the clamp bolt.
port doors can be opened in either spot.
battery access only in normal location
the design has a fairly large cavity in the base, making it light. should any shutter vibration forensic detectives want more mass, i can offer a steel insert, filling the cavity and adding some mass
material is black anodized aluminum, finely machined and finished and will fit arca and RRS clamps in landscape and portrait orientation.
these will sell for $150
FWIW, I think this comment is an over reaction. It's clear that Jim feels most customers prefer to keep the weight down on their L plates, but for those that want more mass he can make the plate heavier. I think that kind of flexibility should be applauded and he made the comment in a humorous way and added a smiley face to boot. Anyone who takes offense at that is too thin skinned IMHO.If you are out in the marketplace trying to sell a product, it is generally best not to insult your potential customers, i.e., photographers who are concerned about maximizing image sharpness and those that shoot verticals.

First, you have to decide if you want to 'couple' or 'de-couple'. Since the audio industry can't decide, it would be hard to be definitive about this.Has anyone ever looked into using an anti-resonant compound in the base of the L-Plate, similar to the material used in Audio component cones and feet? Just wondering if this would help. I am not an engineer.

First, you have to decide if you want to 'couple' or 'de-couple'. Since the audio industry can't decide, it would be hard to be definitive about this.
On the other hand, the audio industry has made an entire realm out of folklore and mysticism, so why not get that going in here, too? I personally have produced photos with much higher fidelity and clarity, and a more stable and distinct focus when I have had Shun Mook dots taped to the body. Three wasn't enough, though. I needed at least four evenly distributed to produce a pleasing effect.
In all seriousness, this shutter slap effect is not resonance, so I don't think any of these approaches will be useful.
Mass and adequate support stability will address it. I have yet to see a person with a well-mounted camera that will suffer much from the shutter. K-H is doing some pretty extreme tests and the slap is visible, but I believe that there are ways to address this for the very long focal lengths that he was testing.

couple of things:
i have no idea why hcubel felt i was insulting anyone, certainly not my intention. there have been several suggestions that perhaps the most endearing feature of the A7/A7R is the light weight and small size and i can endorse that.
those extra holes are fixturing points for machining and anodizing
and the little slots indicate the lens centerline (will be on the L-plate as well).
i avoided adding tripod holes, problematic in this design, since the point is to offer an L-plate; the main function being quick change from portrait to landscape and more or less assuming a clamping plate, not a screw.
finally, i tend to keep one of these on my camera all the time if i am using a tripod for even 25% of the time. the base has to feel good in the hand; so it is full length, smooth and rounded and even the L-plate is a gripping assist
re tripods: a while back on this forum there was some testing of vibration of aluminum, wood and CF tripods; guess which came out on top?
