My sole beef with built-in extenders is that they add length to gear. Sometimes space isnt an option especially on handcarry.

Thanks for the correction!No other than Chuck Westfall confirmed it. As to when we can expect a 100-400mm DO was not answered.
Hello Osbourne Effect.
Nowhere does Mr Westfall or the article state the 100-400 will use DO.
If I understand the article correctly, there are two issues- replacement of the aging tele zoom, and developing DO and bringing the tech into cheaper lenses.
Of course, whatever works for a professional, he or she will use it- these rigid boundaries are merely theoretical.CFast is the designated replacement for CF cards. CF cards are based on the PATA bus so are constrained to 167MB/s of UDMA 7 spec. Now CFast on the other hand uses the SATA bus that is currently limited to 600MB/s
I am not very familiar with CFast. They seem to have been around for a while, why hasn't any major manufacturer started using it yet? What about the Nikon XQD cards?- I believe they can write as fast as 500MB/s (the newer version might be even faster)
While not as fast as the CFast, SDXC UHS-II cards can now reach 250MB/s write speeds.SD form factor is suitable for consumer and space-constraint application.
Both the 7D and the 7D2 use the same AC adaptor kit.... so that means that the battery is the same physical size, has the same pin-out, and uses the same voltage.... but the new one has the capacity increased from 1800maH to 2050maH (according to rumoured specs). The two batteries can be used interchangeably in cameras, but rhe new version needs the new charger to chargeJust like the 1D X's battery I do not think a new charger will be required all the time. Reliability of fully charging may not be guaranteed all the time but it did work with me.
