New Canon Patent for EF 180mm f/3.5L IS, Lens in the Works [Rumor]

By Anthony Thurston on March 13th 2014

Canon has several new patents out, one of which is a new EF 180mm F/3.5L IS. According to the rumors, this lens is in the works and could be announced anytime (or not at all, it is just a rumor).


Among the interesting features of these new patents, which include the 180mm, 200mm, and 300mm variants, is the addition of a new ‘Hybrid’ IS. What exactly that means, we’re not sure, but it is an interesting addition to say the least. I am silly and totally overlooked the fact that apparently the Canon 100mm F/2.8L IS Macro has this new Hybrid IS in it, and the description is available on Canon’s website. “This is the first lens on the market to incorporate Canon’s new Hybrid Image Stabilization Technology. Hybrid IS effectively compensates for both angular and shift camera shake during close-up shooting”


The following patent information is courtesy of Google Translate, so please bare with me if anything does not make sense. It is likely just a translation flub, if you happen to speak Japanese, you can find the full patent details here.

    Considering how aswesome the Sigma 150mm f/2.8 EX DG HSM OS Macro is, I’m surprised Canon and Nikon haven’t bothered to compete in the macro scene any longer than 100/105mm. This is a long overdue focal length! I only wish it were f/2.8. Sigma has managed to pull off f/2.8 for both 150mm and 180mm, without really breaking the bank or going overweight. Meh, Canon.
