What lenses are noticeably softer with D2X

Discussion in 'Lens Lust' started by AFS, Jul 26, 2005.

  1. Hello....
    I've heard with the D2x comes a certain.....weeding out of lenses that do not have good enough performance for the 12.4mp DX sensor.
    Considering that the D200 is rumored to be 10mp+ (chasseurs d'images allegedly reported 10mp, sept. announcement and dec/jan release) and the interview with Mr. Goto of Nikon stated it would possibly exceed the D2x in some areas (near-equal resolution?), I'm wondering if some lenses will be outresolved by the D200.
    So my question is this....
    What lenses have noticeable softness on the D2X compared to previous cameras, film and digital?
    I know the 70-200 VR is not as sharp wide open on the D2X as it is on the D70 for instance. What else?
    I need to know what will be safe for current and future lens purchases...I want to be sure I have good image quality for the next couple of years with a top of the line set of lenses. I figure the D2x will be a good barometer for my time in the 9-12 MP arena...figure at least 2 years :)
    Feel free to tell me I shouldn't worry, that its all a figment of the D2x owners' imaginations, or its not as bad as it seemed before.....

    Hi AFS,

    None that I have. I shoot with AF-D type Nikkors and in fact have a problem with too much sharpness.

    Clients are not interested in seeing all their blemishs - they want to look good, thats what they are paying for.

    A 12 mp camera portrait is brutal in detail.

    I'm using 17-35, 35 and 50 mm and there's way more quality in there than I need.

    I disagree that the 70-200 VR is not as sharp wide open on the D2X as it is on the D70. It appears to me to exhibit similar sharpness and contrast when compared at the same image magnification. It is true that this lens is not as sharp on the D2X when wide open as it is at f/5.6-11. This same behavior is seen when using it on an F5 with film . In fact I do not know of any lens that is as sharp wide open as it is when stopped down a bit; the 70-200VR is better than most, and amazing for a zoom. Even when shooting at f/2.8, it has very little edge softness due to curvature of field and no significant chromatic aberration, and merely loses a bit of contrast and/or sharpness, particularly at the long end.

    I do have a Vivitar Series I 28-105mm f/2.8-3.8 manual focus zoom with serious edge softness on the D2X. In fact with the D2X I could measure the curvature of field of this lens when wide open by using the various focus brackets. I bought this lens in the mid-1980's (I think, for around $150-200) to use on my F2 when I got tired of constantly changing lenses while chasing my (then) young boys around the house and yard; it was my first zoom lens. I suspect that careful examination would show edge softness in my old slides and prints that were taken with that lens, but my wife would not care since her son's faces were mostly near the center of the frame. :)

    In addition to the 70-200 VR, I find the 17-55 f/2.8 DX is really excellent, again except for some minor edge sharpness loss when wide open, and a bit of CA particularly at the wide angle end. Neither of these are serious problems, and are hardly visible except in huge enlargements; this is now the lens I use most often on the D2X. My 60 mm f/2.8 Micro and 50 mm f/1.4 perform as well or possibly even better on the D2X with its smaller image circle, than they did on the F5. Also my old 105 mm f/2.5 and 55 mm f/3.5 Micro are usable when given enough time for manual focus. None of these lenses are perfect, but they have not shown any particular problem with the D2X that could not have been observed previously when using film.
