I would assume tripod but only Daniel can say for sure. I didn't see anything that looked like camera movement in the colour file (but yes, self-timer of course is needed.) Ditto the different shutter speed; I assumed that was due to slight change in light, or different sensitivity of the sensors.
Ditto. Given the reduction of light reaching the sensor proper caused by the CFA, I'm not sure it will ever be possible -- or even desirable! -- to synchronize the shutter speeds for both cameras. So long as the shutter speed is high enough to prevent motion blur, the same apertures and ISO settings are used, and the resulting exposures are visibly similar, then that's plenty good enough for me and my purposes.
Speaking of which, mine here is only to determine whether the converted camera is likely to produce better results for me overall than a non-converted camera. I'm not looking to perform rigorous scientific research or prepare a scholarly review comparing the converted and non-converted cameras, but merely determine if there is a consistent, visible difference between the files these two cameras create in favor of the converted camera.
If there is, then I will buy another A7R, have it converted, use it for my photography and determine, over time, whether it provides a better solution for me and the photography I do or not. If it does, great; if not, then that's unfortunate, but because the type of photography I do is fairly unique, evaluations done by others are usually not very useful to me, so the only way I'm ever able to determine whether a piece of gear will work well for me is to actually buy it and try it.
I certainly wish this wasn't so, because I am not a wealthy man -- far from it, in fact! -- but my experience over the past nine years has shown that I have no other option, because I've been fooled too many times in the past when I rely on the opinions of others for anything but initially screening likely candidates. <sigh>
From my perspective, I have to remember how much I value being able to work with the colour channels, and how much I hated carrying around colour filters with black and white film.
This is my primary concern as well, although my issue isn't so much carrying filters around, but not being able to, in effect, create a custom filter to optimize the B&W conversion for each and every photo. If capturing more detail also means living with less-than-optimal tonality, then I'll grudgingly choose tonality. But as I said, this isn't something I'll be able to determine solely by experimenting with a handful of photos taken by someone else of scenes that differ markedly from those that I photograph.
All I need at this point is to see enough promise to justify taking the next step and acquire a converted camera so I can evaluate it first-hand and at length. And based on what I've seen so far, I'm very, very close to doing just that....
