Has no one noticed the sticky Adam has posted yet, which mentions that he will have the information released at 10am tomorrow for
"SMC Pentax-DA 18-135mm F3.5-5.6 ED AL [IF] DC WR"
I think that has leaked more information that we've had before. Both ED and AL glass in it, plus internal focusing.
But what can "DC" possibly be
The only thing I could think off hand would be something like "direct control"--i.e. it allows for aperture control, etc. in video recording. Of course, it could just be a typo, with Adam having a Sigma lens in mind. Do tell, Adam
Let the final speculation begin!
Edit: Just had another crazy idea: DC could be related to the focusing system the lens uses.
