sneak preview: Canon EF 28mm f/2.8 USM IS

Why IS in a 28mm lens but not the 35, 50 or 85 primes or indeed the 17-40 or 24-70 zoom? I have the 17-40 and it doesn't need IS IMHO. Look forward to the test and your opinion of the value of IS in a WA lens.



BTW Klaus, are you preparing for Oktoberfest, or what?

This lens is specifically meant for dslr video, as is the 24 F/2.8 IS. And it being F/2.8 brings IS into the realm of possibilities (relatively small lens elements). The fast primes are built rather tightly, especially the fast ones (little to no space left between elements and groups), and have very large glass elements. Adding IS would require a complete redesign, add elements and groups, and the question really is how easy it would be to do, and how cost effective, apart from potential issues with decentering (larger with larger elements), bokeh, etc.



Kind regards, Wim
Gear: Canon EOS R with 3 primes and 2 zooms, 4 EF-R adapters, Canon EOS 5 (analog), 9 Canon EF primes, a lone Canon EF zoom, 2 extenders, 2 converters, tubes; Olympus OM-D 1 Mk II & Pen F with 12 primes, 6 zooms, and 3 Metabones EF-MFT adapters ....
