new stuff from Canon (EOS 77D, 800D, M6, 18-55mm f/4-5.6 STM IS) - Arthur Macmillan - 02-16-2017

Wait, what?  This is the same lens tested on a 15mp APS-C isn't it?  The same one that came with my D70?  Yes, I am the proud owner of three different versions of the EFS 18-55mm Kit lenses.  I think they all work pretty good, and are virtually weightless.  Have decent close focus.  Ironically I used the older two quite a bit.  By the time I got the 18-55 STM, I had The EFS 60 Macro, and the EFS 17-85, so no reason to use what is probably a decent lens!

For a pentaprism, look at the heavier 80D.

 

They cheapen the xxD line with this move!  Is there a shutter speed difference too, or have they morphed the consumer and prosumer models into slight of hand feature swap?

No. This is the Canon EF-S 18-55mm f4-5.6 IS STM. Not the EF-S 18-55mm f3.5-5.6 IS STM.

 

New lens:
  • 215 grams
  • 67mm diameter
  • 62mm length
Old lens:
  • 205 grams
  • 69mm diameter
  • 75mm length
They shaved 1/3rd of a stop at the wide end for a 20% size reduction. As far as I can tell, the MTFs for the new one are slightly better at the wide end, and slightly worse at the long end?

Anyway, the optics have changed dramatically:
