    E5+Zuiko 13-35 vs D3x resolution charts

    I just got 14-35/2 Zuiko and took some quick resolution chart pics.
    Also included d3x chart from DPreview
    What do you think? (5MB jpeg downloads)

    My test chart is just a page torn out of a photo magazine. Obviously because of the small size it must be shot from close up. Hence the difference from the clean dpreview chart look, which must be big and shot from far. But the trumpet lines coalesce just as fine at resolution limit.
    As a rule of thumb, MTF50 is where they are still seen very clearly/contrasty as separate, MTF30 where you manage to see them still separated, MTF10 they just mix together (although it's possible to count them--barely).
    It looks DPReview gives MTF 30 figures.
    DPReview gives the resolution of D3x here:
    http://www.dpreview.com/reviews/nikond3x/page32.asp
    Note "prime lens was used" at f9 (presumably the best lens).
    Frankly, I don't get what they mean with "extinction resolution", I see only grey there.
    My test was gun'n'run: the "resolution chart" in available light and E5+zuiko on tripod. The Zuiko is a zoom of course, this particular shot at 14mm/f4.
    But frankly , The Zuiko is very, very consistent and it looks the same at all f-lengths and f-stops until diffraction kicks in after f11.
    Can't wait for DPreview to show their resolution tests for proper comparison.

    thanks nugat

    can tell you right now they will use the 50/2 in the review
    and they usually shoot sub-optimal f6.3 where the lens performs at its very best at around f4. 50/2 will print around 47 lpmm at f6.3
    The 35-100 and the 14-30/2 exceed the resolution of 50/2 at f4 at around 52 lpmm

    I'm sure the IQ would be very good with E-5
    If weather is fine why not just go out and shoot with it
    I would
