APM MS 16x70 ED Apo First Light Impressions (Daytime)

I took delivery yesterday of the new APM branded magnesium 16x70 ED binocular, and today I had a brief opportunity to compare it with my Lunt 16x70 magnesium.  A small modification to my Uni-mount facilitated mounting the binoculars one on top of the other, ideal for fast switching from one to the other. Physical characteristics are all but identical so I'd conclude the only differences are in the optics. This becomes evident when switching from one to the other. The APM is just that bit brighter and more colour neutral. Chromatic aberration is evident in the Lunt under certain scenarios, although that said,  it's very well controlled and far from objectionable. In comparison the APM is remarkably colour free.  More to follow when the weather cooperates and I get it under the stars.

Sort of expected if less light is being lost into the spectrum, especially off-axis. Have you yet been able to assess how much brighter it is on-axis?

Not as yet Steve. Between work commitments and the weather conditions continuing to be far from ideal when I do manage to get a few minutes, I haven't really had any quality time with it. I've a few days off over the coming weekend, so fingers crossed by then the weather will have improved and I'll get back to it.
