    Question Quality with 2 equipment configurations

    I would like to focus on the question of sharpness and resolution in two photographic equipment configurations.
    (Angles, depth of field, distortions, etc. are secondary to this question).

    I'm going to photograph the same object (children) from the same place, the same ISO value, the same illumination, etc.
    The two equipment configurations are:
    A. Nikon Z6 with Nikon lens 24-120 at 120 mm (with suitable adapter of course).
    B. Nikon Z7 with the Nikon 24-70 lens kit at 70 mm.

    My question is:
    Will the image obtained in the A configuration, will be the same quality (sharpness, resolution) as the image obtained
    in the B configuration and performing the appropriate crop with PS ?

    Welcome aboard. Enjoy the ride.
    We look forward to seeing more posts and samples of your work.

    No way will they have the same sharpness and resolution. First off the Z6 is 24.5 Mp resolution vs the D7 45.7Mp, hence the D7 has almost twice the resolution of the D6. Second, with a subject as active as children, you will not be able to get the same pictures, try a still life of something that will remain stationary. Finally, I am pretty certain the 24-70 lens is sharper than the 24-120, plus I would recommend using the same focal length (say 50mm) on both lenses).

    It seems to me what you're really asking is, "Am I better off (or what are the differences, etc. (however you want to look at this)) shooting with a crop-sensor body (APS-C) and using full resolution images, or a with a full-frame sensor and and cropping the image in 'post?". Your specific question, I think, muddies the water significantly by introducing an additional lens into the equation. However, that being said, I suggest you watch this video which gets to the heart of the matter: FX with cropping vs. DX at full resolution:

    This is really about as far as I'm willing to tread on what I see a "down the rabbit hole" conversation.

    Thanks
    I meant to photograph one boy - a portrait. So I use a 120mm focal length.

    My answer remains the same.

    The New S Line lenses are the sharpest lenses currently on the market and FAR superior than any F Mount lenses ... So you will not get better results with an F Mount lens

    It is kind of an apples and Oranges. You are taking two full frame cameras and on the one withe the highest resolution you are using a good lens on the one with half the resolution.

    I could not tell you but my first thought is that the Z7 with the 24-70 f4 S would be better. I love the result I have been getting with the Z6 and the 24-70 f4 that I have.

    My suggestion is to rent the components and test it.

    I would guess the 24-70 f/4 is going to be sharper than the 24-120 regardless of which camera it is mounted on. Portraits are not as critical for resolving power as many other subjects, even with large prints a 24 mpx sensor is not going to be as limiting as the display medium, printer or screen. The appearance of sharpness is not that much based on the resolution as micro contrast, edge contrast, color gradient etc. If you do not have good light those suffer and will make the image seem less sharp. 12mpx is high enough resolution for very high quality of portraits....with good light.

    What will be the end use? If it's an 8x10 or 11x14print, I don't think you'll notice a difference.
