 p.1 #9 · p.1 #9 · Suggestion for critical manual focusing pls. | |
While focusing you will never see the full pixel detail from the D800 because the camera omits rows of pixels. That affects LiveView and anything external that sees what LV shows it, including cameras and zacuto finder.
You can enhance contrast and sharpness settings to "improve" the LV image but if you go too far then everything will look sharp even when it really is not. Plus general image previews will look way overcooked.
I have not yet tried shooting with a tethered computer. I'm guessing that it offers a better pixel view but I don't know if it does so before taking a shot or only after taking a shot (in which case you would not see the effects of any changes until you take another shot).
A magnified viewfinder image only helps for seeing the middle of the image, which is not the best way to judge the setting up of a PC-E lens.
I've tried a DK-17M magnifier and found that the bottom and top of the viewfinder image were not focused the same, as if the magnifier was not mounted incorrectly. Not sure what is wrong, but to see best overall focus I have to lower my viewpoint off-axis and then I cannot see the whole viewfinder image. I've abandoned the DK-17M option for now but one day I will try it out on my D3s for comparison.
An external accessory that has its own focus assistance in the form of flashing highlights at areas of high contrast - which we would hope indicates critically sharp focus - is probably the best option if you cannot see it for yourself in the viewfinder.
Unfortunately there is no optional focus screen from Nikon that would work better with a specific lens than the default focus screen. MF with anything wider than f/2.8 or perhaps f/2 is more difficult than it ought to be because of the focus screen DOF characteristics. So too at f/5.6 or f/8 because the focus screen tends to go disproportionately darker.
