New Canon Patent: 17-40 f/2.8-4 Lens

Japanese site egami (Google translation) spotted a Canon patent for a 17-40 f/2.8-4 lens. She successor of the highly popular EF 17-40 f4L USM lens? Looks like. With the new 5D Mark III available in the near future it wouldn’t be strange if Canon decides to upgrade the EF 17-40 f4L USM lens. Surely a good lens for a full-frame camera, and, btw, the cheapest of Canon’s L lens.

    Won’t be cheapest for long then…

    but i don’t think it will be cheap anymore if it renew…. especially for F2.8-4….. (it maybe cheap if keep it at F4….)

    I wonder what Canon’s plans are. Everyone will expect this lens to be more expensive, but the current price of the 16-35 doesn’t leave that much room. Get too close and the biggest advantage of the 17-40 will be gone.

    Will have to think about this a bit, since I’m considering replacing my 17-55 EF-S with the 17-40.
