<p>This optical formula patent is a good sign that we’ll see some kind of replacement for the PowerShot SX60 HS.</p>

f/2.3 to f/7 ???

I hope I read that wrong because if I didn't there are some folks at Canon Program Management that dearly need to smacked up side the head - both sides of the head!!!

I'm a Canon dude currently at 17 rigs, 15 actively used as tools for different gigs/clients. And a boat load of L glass. And yes I do have a couple of bridge rigs and Canon Cine rigs that I use.

But my purchase yesterday was a Panasonic FZ2500. Very happy with what I did.

Canon ...WTF (I sure hope I read that wrong)
