irSimple wireless support built-in, which does up to 4Mbps:
"High-speed infrared data transmission system
The K-r is the first PENTAX digital SLR camera equipped with the IrSimple™ high-speed infrared data transmission system. Since this system allows the user to transfer image data to IrSimple-compatible digital devices with great ease, users can effortlessly post images taken with the K-r on their own blogs via a cellular phone. This system also makes the K-r a brand-new photo communication tool, as it also allows users to exchange their image data using a pair of K-r, and even let them engage in a simple match game using Exif data attached to the images such as aperture or shutter-speed values."
Perhaps that is one wireless evolution path for Pentax. Maybe the K-5 already has irSimple built-in, and just requires a firmware patch to enable it
To the photographerSimple (me) that sounds very much like a hardware thing.
I note from the IRSimple page: "Uses the FIR (Fast IrDA) specification for the speed of the physical layer (up to 4 Mbps)." That's
bits, not bytes.
If one assumes a 20 MB (upper case B) file (raw+ JPEG), one may guess at 200 Mb after the addition of parity bits, protocol/framing overheads, etc. On top of that, we may deal with turnaround time for ack/nack, retransmissions, and the inevitable latency caused by the lower speed of red light in a nitrogen-based medium.
OK, I made the last part up.
When I see phrases like "up to" and "physical layer", I start dividing by two - or ten. Sounds fine for small file sizes from, say, camera phones.
I'm afraid I don't understand how useful this tech would be. OTOH, I'm a devoted Luddite. Proof: instead of Falk's Web-enabled volume control, my audio system uses a ....... knob. I have to turn it. One way is louder, the other is softer. I need that intuitive UI.
