Let the hive mind of Engadget get that for you.
"I love my little computing companion but I often find myself missing a full sized keyboard. I have been looking at several of these portable and flexible keyboards, but I can't seem to make up my mind about which I should buy. I don't want the keyboard to be overly expensive, but I want it to be good quality. Also, how difficult is it to type on these keyboards? Thanks!"
I want a 14mm (35mm Equivalent) rectilinear lens. For the full frame Canon, there's the 14mm F/2.8L, or the Sigma 14mm, Or the Tamron SP 14mm F/2.8. In for the APS-C format K20 there's... nothing. Well, okay, I guess you could do the Sigma 10-20mm, but that's a Zoom. I want PRIMES. :-)
That said, all you Canon users really get the shaft too. How is it I have wireless TTL flash control with my $800 Pentax body, and y'all get a big fat nothing at 3X the price? I mean, I get some of the reasons why they didn't include a pop-up, but would it have killed them to fix mold one into the body like they do with their compacts? Canon owners tend to be pretty loyal, you'd think at the price of the 5D they'd throw y'all a bone. Pretty disrespectful to such a huge and loyal userbase if you ask me.
