On batteries -- I've run across a post elsewhere relaying one person's experience with apparently much improved power pack longevity if the camera is put in "Airplane Mode". Has anyone here tested that?
Shutting off WiFi and NFC in the pursuit of every day power conservation is something I can live with easily.

Yes, raw images converted with Iridient Developer with no adjustments apart from input sharpening and noise reduction (according to Iridient's default A7R camera profile).
My understanding is that input or capture sharpening was to offset the blurring effect of the AA filter and therefore is not necessary for images made with sensors that do not have AA filters. Since I've never had a digital camera that did not have an AA filter, I thought I would see how others feel about this.

I hope that there are some cases when the A7R is better, because I have one in front of me, not yet opened...
I think it's most cases Philippe
I chose A7R too, I want some improvements, not exactly the same quality I already have with my RX1R.
I'm planning to use it with the best glass for the best resolution I can get. Sure it would be great if it worked
perfectly with all my lenses, but even if it does with most of them, it's gonna work better than anything.
BTW my 19R is gonna be here in a couple of days too

It's been here since Friday evening. I need to say good-bye to my trusty NEX 7 first, and get ready for what to do next, else disappointment beckons. Should I expect my Elmar 24 to work as a 28 or keep it as a 36 on NEX?. Should I try my Contax C/Y 25? Should I buy a Leica R 28 vII, or an Elmarit vIII?
Actually, truth is, we've had absolutely the ugliest autumn light, and I just wasn't inspired to pull shots that would just totally suck...

Apparently some folks have self-control which I myself do not possess!
I'm trying to figure out how I can charge some of my spare battery packs so I can open the thing up at the shop when I pick it up this week. I want to head outside with it immediately... if not sooner.

I think someone else tried inserting a fully charged battery before a battery had charged in camera and had some menu issues because the internal battery had not charged. Go ahead and try it, but if you have issues that will most likely be the problem.

Airplane mode can be found at:
Menu > Wireless > Airplane Mode > On/Off
The account I read spoke of shooting > 1,000 frames during the course of a concert, a mix of manual focus adapted lenses and native FE35 lens, with lots of experimentation as the camera was new to the photographer, and having 1/4 battery capacity free at the end.
Sounds awful.
Jeff - thanks for that reminder about the internal battery.
What drives me just as crazy as Sony not including a cradle charger in the package is Sony didn't arrange to have their new charger available before the camera ships.

Not really, capture or "input" sharpening is objective sharpening. Making the original, before any contrast or other post-processing, as sharp as the recorded media/data can realistically carry or "show". Square pixels have their limitations...
When physical resolution was lower like in the Kodaks, the M8/9, the older MF digitals, the original was often already to sharp for its' own good. You had pixel errors in the form of aliasing and moire already before trying to sharpen, since the image data was severely undersampled. Some people think this "looks good" though, but it's really just adding digital crap on top of the ideal image data. Kind of like how you can make an image look sharper by adding noise to it.
So capture sharpening is meant to compensate for ANY kind of blurring induced in the capture, and from a strict PoV you should also do it on the "neutral" image as close to raw linear format as possible.
The distinction between this and "output" sharpening is that the output sharpening has nothing to do with the translation from reality to image, output sharpening is a translation from image to presentation; adaptation. Making the image look sharp(er) visually, or adapting the image to compensate for either on-screen or print presentation.

One can use the camera, but will have to enter the date and time, which will not hold after the camera has been turned off. This is due to the internal battery requiring to be charged, which can only be done with the USB charger
Cheers

WiFi and NFC turned on by default considering that <1% of users will ever use them actually maybe not so surprising considering it's Sony.

Regarding focal length and FE35mm...
Again strictly speaking, focal length is ONLY defined for the optical center. And the Sony FE35 is about 35.3-35.4mm... The focal length has several practical definitions depending on how you want to practically measure it. On a bench I do it with a collimated light source and the Cornu method.
Then you also have distortion. Distortion will either contract or expand the image as a function of distance from optical center, and this does of course change the field of view - but not the focal length! Barrel distortion "pulls in" more object space into the image and makes the lens seem shorter. Pincushion distortion pushes object space out from the center, and makes the focal length seem longer.

That's interesting and from both a practical use and from a teaching perspective, I have never heard it explained like that. I suppose one could think of useable focal length (what's left after distortion correction occurs that might crop the image and give a narrower angle of view) but that would not be technically accurate to how it's measured scientifically as you do at the center of the lens. Angle of View has always been associated with focal length and format size from a working photographers perspective (and that's how it is also taught in photography classes) but technically what you are describing makes obvious sense. http://www.unique-photography-concepts.com/images/I-2A-Picture-of-Angle-of-View-Graph.jpg

Unfortunately it doesn't improve battery pack longevity to shut off WiFi and NFC. I have tested it and found no difference.

I'm definitely sceptical that it could make as big a difference as was reported in this one case. A little testing and logging is in my future. Maybe... I might just shoot the darn thing.
Clear and crisp weather approaches the Pacific Northwest at the same time my camera is due to land. Serendipity!
