PCPhoto Magazine has posted an interview with Canon's Chuck Westfall discussing the future.
Adobe has purchased Pixmantec/RAW Shooter with the intent of incorporating the technology into their new Lightroom product. Interesting, as Adobe already has a RAW converter in Photoshop. Here are some answers to FAQs on Pixmantec's site.

Canon EF 135mm f/2L USM Lens Review
As the 135 is compatible with Canon's extenders, the crop examples include with-extender samples. The review text itself received a minor makeover as well.
For those waiting for the Sigma reviews and for those I promised a Sigma 70-200 review this week ...
My third attempt to find a Sigma 70-200 DG lens that focuses properly was unsuccessful.
To keep things moving, I decided to evaluate the lens using manual focus only.
As it turns out, the lens also has an image quality problem in the upper right portion of the frame rendering
the ISO Crops (and everything else I shoot) quite blurred.
Preliminary results indicate that this is a nice lens but obviously I am running into some quality control problems.
Unfortunately, this has cost me a lot of time with no results to show for it.
I want the reviews to be accurate, so I will once again delay this review until Sigma fixes the lens.
Reminder: The Canon USA rebates end in a few weeks.
If you are in the market for a
Canon EOS 5D or a
Canon EOS 350D,
now is the time to act.
