You're right, real video isn't needed for EAA viewing but it's a nice default capability that makes working with the camera in real time very easy. I don't see it as crippling the A7s but it's certainly not the be all and end all of using the camera. The A7s can obviously do more than real video for EAA type of viewing but so far it appears that the software is the limiting factor. I agree 100% with your desire to see the workflow, as many folks know (and are probably tired of me saying) this is a pet peeve of mine for many of the images presented here in this forum
I don't know if I'm really representative of a "typical" (whatever the heck that is) EAA viewer but I want to be able to easily view images as they come from the camera. I don't want delays in presenting the images (but understand the issues of large amounts of data on USB2 interfaces). I would like to adjust the images for brightness and contrast and perhaps some color (individual color histogram control for example). I want to be able to adjust the exposure length and perhaps the gain of the camera. I want all those capabilities on the screen at the same time, I don't like to go hunting for stuff in various menus. I simply want the images coming off the camera to get as close to the simplicity of live viewing at the eyepiece as possible (a few mouse clicks are ok as well) ... it comes down to viewing over manipulating. I also want to occasionally capture what I see on the screen, but I'm not really interested in spending a lot of time capturing and managing various images to create pretty pictures.
The fundamental problem is that software that fulfills my needs is very rare. It has normally only been associated with astronomy oriented video cameras but something like the Starlight Xpress Live software also appears to meet my needs with a USB connected imaging oriented camera. So far I don't see anything similar for the A7s ... but something like BYEOS appears to be a step in that direction for DSLRs, so perhaps there's hope. The other direction is the AstroLive software you mentioned that started out on video cameras but has been designed from the outset to handle a much wider variety of cameras. Kyle's software certainly also gives me hope ... but I too wonder about the business model (the amount of work to add new camera support vs. the revenue it generates).
So simply put I love the technology of the A7s (I really hope it soon drives lots of similar but lower priced alternatives) but beyond an expensive and impressive video configuration I don't see the whole package (camera and control/display software) being appropriate for my type of EAA viewing ... yet.
