Due to a great planetary alignment I have had a chance to quickly look at the new EF-M 11-22mm f/4-5.6 IS STM lens in the flesh on an EOS M camera.
Like all the EOS M system lenses the build quality is impressive, I really think Canon needs to look at the EOS M lenses for the direction to go when designing and building their regular kit lenses. It is a combination of solidity and smoothness that gives the impression these are something special. However EOS M system lenses do command a price premium over regular EF-S kit lenses.
Locked up – keeping a low profileFirst thing I found was that the lens features a lock switch that is used to “compact” the lens for storage and when not in use. This ensures it maintains it’s compact dimensions, but means that there is one more step to “unlock’ the lens before you can shoot with it. Unlocking the lens to allow the zoom to move to it’s regular 11-22mm shooting range and causes the lens to grow in length.
As shown above the lens increases in length when unlocked; I’d estimate the lens to be around 25-30mm longer than it’s official 58.2mm in this position. When the lens is zoomed from it’s 11 to 22mm it also changes in length – like many zoom lenses do.
Quality bit of kit?
I was not able to shoot and keep pictures with the lens, but from on the camera LCD screen looks it seems relatively immune to flare and the edges also appeared to be free of chromatic aberration – though it’s much harder to tell that just on the camera LCD. I’ve been told that the quality of the lens compared to the great performing EF-S 10-22mm f/3.5-4.5 USM lens is not something to worry about and that the MTF chart for this new EOS M system wide-angle lens is pretty much a flat line from centre to edge.
