Re: A or M 1.7 Vs. 1.4? (Different 1.4 optical designs)

[Andre Langevin]

So, I'm still confused.  Which is the best-the K, M,
or A 50mm 1.4???

Steve

Sorry Steve if my long e-mail has been confusing.

Usually it is said that the K and the A lens (and later auto-focus 1.4) are better than the M. The differences are subtle and one particular M lens might be better than a K or A lens. Two M lenses I tried had low contrast wide-open. K and A lenses should be better in this regard but they will still show quite low contrast (as almost any other 1.4 lens wide-open).
