  1. You could just add a WR-R10 + WR-A10 to the 10-point connector and it performs the following functions: - triggers SB-5000 flashes by radio, with full functionality, flash control settings in the menu (I have them in my menu, very quick to access). Fires the flashes very reliably indoors and outdoors, unlike optical triggering, no frequent eye closures like the pop up gives, no long recycle times, you can fire at the pace of the remote flash which in the case of the SB-5000 is very fast - allows one to trigger the camera remotely without a cable (using WR-T10 which comes with the WR-10 kit) - allows one camera to trigger other remote cameras. - you can continue to use your old flash in the hot shoe together with the radio triggered remote(s). The SB-5000 is expensive, admittedly, as a new unit, but it does have advantages: the flash is surprisingly small, compared to SB-910/900, it has a fan so it keeps itself cool, and allows fairly rapid firing at or near full flash energy. It has the radio receiver built in and so since the WR-R10 doesn't need a battery either the radio triggering is carried out entirely without requirement of maintaining extra batteries for the triggering devices, just keep the flash itself and the camera charged, and you're good to go.
  2. Since this would require completely immobile subject over time (or expect artifacts), I find very limited interest in such technologies. I'm used to reconstructing stuff from incomplete data and it really is a crap shoot - it can work, or not. Thus it is essential that the process is not done by an automated in-camera algorithm but with plenty of user control on a real computer.
  3. That could be very complicated as Nikon seems to change the protocol quite often to accommodate different lens types. And these protocol specifications are not public. Furthermore, I am sure that Sony wants to make money by selling their own lenses instead of helping Nikon or Canon make money. I believe to achieve good AF performance on a mirrorless camera, it is essential to provide a motor that can perform small adjustments to focus precisely and reproducibly. Ultrasonic motors perform large focus movements quickly but they seem to stutter about a lot when used with contrast detect AF. The new Sony 70-200/2.8 FE includes two focusing motors: one is the ring ultrasonic motor, and the other apparently a linear motor. My interpretation is that the ring motor is used to fast changes over long distances and the second motor performs precise fine adjustments. To get this kind of performance Nikon lenses would need to be revised with similar motor configuration, or at least a stepper motor in place of the ultrasonic. Nikon have been introducing a few "AF-P" lenses with stepper motors but so far they are consumer entry-level zooms. The live view AF on compatible Nikon DSLRs becomes suddenly very similar in performance to mirrorless cameras: no stutter, no noise, the focus just snaps silently in place. I think Nikon made this change to support better live view and video AF but also it is something that is likely needed to support good AF on any future mirrorless platform (through adapter or not). Canon's STM lenses are similar and they also have made several primes with that technology. Sony is definitely thinking out of the box in their numerous new technical solutions but I don't know if the advancements help users of existing non-stepper motor equipped DSLR autofocus lenses. I suspect all-new lenses are required for best performance.
  4. I think shooting at high frame rate is completely pointless at an event like White House press conference. I think 3-5 shots should be enough to capture the spirit of the event visually. There isn't much happening. The noise problem is created by numerous photographers shooting at high frame rate and accentuated by poor positioning of microphones.
  5. There are no native fast superteles (300/2.8, 400/2.8, 200-400/4, 600/4 etc.) available for the mount (with adapters, full performance is not available) so I find it difficult to believe photographers who specialize in sports could switch (not to mention the cost of switching, if the lenses were available). If Sony had launched at least a couple of those lenses at the same time, it might have made a different impression of who the are targeting with this camera. However, for other applications where silent operation is a significant benefit, and fast long lenses are not required, this camera seems very interesting. I imagine some wedding, music, theatre, dance photographers would love it.
