When Canon updated the EF 24, 28 and 35mm they added IS at the expense of an F-stop or so but it was a good update in the intermediate lenses. It feels like the same update process should be coming for the EF 50 1.4, EF 85 1.8 and EF 100 2.0 as they are getting quite long in the tooth. I love my 50/1.4 and don't think I want the new 1.8 as I would prefer a photographic lens to a video lens. The STM lenses are great for video on my 70D but it's not my focus (pardon the pun).
You are mistaken, sir. No IS refresh lens was slower than it's predecessor.
The EF 24 f/2.8 was obsoleted by the EF 24 f/2.8 IS USM.
- The EF 28 f/2.8 was obsoleted by the EF 28 f/2.8 IS USM.
The EF 35 f/2 was obsoleted by the EF 35 f/2 IS USM.
All are like for like speedwise. What confuses folks is that there is ALSO an EF 28 f/1.8 USM, so folks thought that the new 28 IS was a slower lens, when in fact both are still sold side by side.
And all of the above were
entry level lenses
without USM -- they had squeaky terrible AF motors and a host of issues.
The
intermediate non-L, non T/S primes all have USM -- the 20 f/2.8 USM, the 28 f/1.8 USM, the 50 f/1.4 (Crappy) USM, the 85 f/1.8 USM, the 100 f/2 USM, etc. We still haven't seen Canon's plans for refreshing those, but the 50 is screaming for replacement.
