Has the M-Series Arrived?

[Kayaker72]

I haven't yet found what I would call a reputable review of the EFM 18-150. I have seen a couple of videos from people I am not familiar with and the IQ does look pretty good. Most of my interest actually comes from the MTF chart:

What I see is pretty impressive. Starting at 90% transmittance wide open both at 18 mm and 150 mm, but getting into rarefied air by f/8 (I am assuming the light blue line is hidden by the thicker lines above). Not only at the center, but the theoretical transmittance is pretty even across the frame.

Compare that to the EFm 18-55, which is my current main lens on my M1 (and I am happy with)

The EFm 18-150 is just better. Period. Across the board.

Compared tot he EFm 55-200:

Again, I would take the EFm 18-150. The 55-200 isn't awful, but edge of from is going to have issues and even at the center of frame, f/8 is at ~90%.

But, the EFm 11-22 still reigns:

For a small UWA lens, no wonder Bryan's tests came out like they did.

Anyway, the MTF has me very interested in the EFm 18-150. We will see, but if I choose to keep my M kit, I could see swapping out the EFm 18-55 for it.
