Assuming that they have gotten rid of the horrible shutter vibration and noise of the old A7 series, which they say they have, and with the EFCS which they have added it would be a much lighter alternative to my beloved D810. I am no longer strong enough to carry the D810 and 2-3 lenses all day long.

Does anyone know what the advantage to having a backlit sensor is? They say it's going to have even more DR than the current lineup of SONY/Nikon sensors... but I'm ot sure that this is due to the backlighting or not.

I have use the A7II and it's ergonomics are much better that the A7... but the SONY menu system is horrid. If they can't clean that up it would be a deal-breaker... assuming my knees and back don't get worse.

I think thjat given Nikon's success with SONY sensor's the next Nikon will have something close to the A7rII but tweaked to Nikon's specs.

One worry for me would be how to clean a 5 axis sensor without destroying it.

BSI sensors moved the circuitry off of the front of the sensor to the back--well, at least beneath the photodiode layer--leaving more surface area to collect light since that area is no longer being taken up by circuitry. The smaller the chip, more significant the gains since the circuitry took up a much larger percentage of the surface area on a small chip compared to a large chip. The stacking technology is getting the circuitry into its own layer rather than a substrate of the same layer as the diodes. (The layers are then stacked together.) Supposed to lead to less crosstalk / interference and therefore less pollution of the photon data.

It allows for a slight increase in sensitivity, all else being equal, but in this case probably more importantly, much faster sensor readout. That last part has always been a handicap, especially for larger sensors. They claim a factor 3.5 improvement over the 36MP sensor in the A7R (and D800) in terms of read out speed. Which probably explains why they now incorporated on sensor phase detection (which requires fast readout) and claim fast AF, even with native DSLR lenses (using adapters).
 
Very exciting. Can't wait to see what Nikon will do with that and how they plan to compete in the next couple of years.

The A7rII has a vibration-reduced shutter rated for 500k actuations and even better, a fully-electronic shutter mode as well like the A7s, the latter which was made possible by a 3.5x increase in read-out speed of the sensor by moving to BSI.

Are you sure about that one? That's a global shutter! I don't think it's possible on 42Mp BSI FF sensor. Not at the current tech level anyway. Maybe in 5-10 years.

It's not a global shutter - just a much faster rolling electronic one. My guess is it can read the full sensor somewhere between 1/50 to 1/100, based on the A7s's 1/30 readout rate.

This sensor might be to close to the D810 in terms of resolution, DR and high ISO sensitivity. I think it is more likely that we will this sensor in a Nikon FF mirrorless system with F-mount.

The next high-res DSLR (D820 or D900?) potentially will be based on a new sensor also used in the speculated A9 camera and will deliver resolutions beyond the Canon 5S/R sensor. It´s still to early for a D810 successor...

Sony just dropped a monster cam on the market, the A7R II. 5-axis stabilization and a 42MP full frame sensor with 5fps and 4K video. Not bad Sony.

Is this the sensor that might show up in a D900? Or will Nikon match or exceed Canon's 54MP

Hope so, I would like, if I am still around, to pick up a Refurb D810 or D810A in a year and a half or so, for about USD 1,700.

And the release of more new amazing cameras with people clamoring for them, will help drop the price.

It may well be a Toshiba sensor in the D900 and a Nikon designed amd contracted sensor in the D5. Tje Sony Nikon relationship on sensors may well slpw down now.. The new wave of tech coming from Nikon with 173 point AF will allow Nikon to seperate itself again from the mirrorless gains.

While I really liked the Sony A7 line when I've played with it at trade shows, it's always been demonstrated with the small, light lenses: a prime and the 28-70mm kit lens.

Once you put something "real" on it, it's just as heavy, although slightly smaller in most cases, as the equivalent Nikon lenses.

The Sony 70-200 f4 is 29.7 ounces (1.86 lbs). The Nikon is 1.87 lbs. Sony's 28-135mm f4 PZ G OSS takes 95mm (!) filters and weighs 2.7 pounds. It really makes the body size and weight hardly relevant. If I were to go with Sony, the equipment would fit in the bag a little easier, but it wouldn't make it much lighter. I'd have fewer lenses, but that's because Sony doesn't make equivalents to all the Nikon models I have and use. I'd love a lighter kit, but Sony doesn't really get me there unless I give up some lenses. As to the picture quality, that's a wait and see. If the Sony got truly superior images, I'd have to consider it, but at $3200 for the new body, I wouldn't be happy about it.
