    Digital Lens on Film Camera , Film lens on Digital Camera

    I will post a detailed article from lensrentals.com.

    If you have a digital lens and if you use it at film camera , result will be bad. Why ? Because digital lens is optimized to to send light rays through the glass infrared mirror.

    If you attach film lens in to digital camera , glass infrared window will decrease the mtf %20 and increase the spherical aberration.

    Thats why , glassless BW Leica M9 is the best for accepting old lenses.

    I don't worry about such matters because I only use Canon FD cameras and lenses.

    Oh Hogwash!
    Also, the comparison is what between 2 or 3 lenses? Every system currently has at least twice that number. One could spend a lifetime comparing, if there was to be a "generalisation".

    Also, What you are suggesting is very local to cameras without AA filters? (is it?) If so - wouldn't it mean that all current MFDBs attached to older cameras (V series, etc.,) would be out of whack?

    One of the better things about the Nikon system (SLR, not mirrorless) is that you have compatibility for most things right back from somewhere in the 60s to now (at least mechanically).
    I have used a current Dx "G" lens on a Mechanical Nikon and images came out fine - incidentally I shot them all at f22 cos it's a "Gelded" lens.
    Have also used the 50 f1.4 AI on then current D90 and it sparkles.

    meh,, nikon seems to work fine for me

    tomAtoe-- tomahtoe

    btw ...

    the arguments that the plane of focus will be off
    is the same stuff that i always heard and was warned about
    when i was told NOT TO use my normal graflex 23 roll film adapter
    on the back of my graflex series d slr.
    so i put it on ( used black masking tape ) and took a few rolls, wide open
    with my tessar 21cm f3.8 ... focus sharp as a tack.
    people just like to claim stuff and once in a while i turns out not to be true...

    The whole thing seems a bit off to me. Adapters vary in equality, and fit.

    At the same time is every sensor, from a given camera maker, equipped with the same thickness and quality of glass in the stack?

    Did Nikon and Canon lock themselves into a set filter thickness/composition for all time and eternity?

    It would be interesting to know if filter stack thickness has changed as sensors have evolved?

    Then again, what about emulsion thickness? Which is optimal?

    Or, are the differences too small to matter?

    Erm... what??
    More likely (only as a possibility) it is chromatic aberration, not spherical. But infrared?? I don't think so.
    No, I don't believe the "decrease in MTF of 20%". How is this qualified, and in what specific circumstances?
    Articles like this are very generalised, vague and wordy. This should be better researched, published, subject to peer review, analysis and proof, and then cited. Some of us are not easily taken in by bald statements. And is it important? If proven, it might be. For what it's worth, all of my analogue lenses are totally functional on digital bodies (old and newest) without problem because they are from the manufacturer, not a third party — and that is where many lenses do give problems with bodies, especially digital (the marques do not licence metering and AF algorithms to third parties). And no, I don't have a digital to take those lenses because I do not use digital for my production (and never will).
