Nikon Lenses help. Which Nikon Lenses is the sharpest from these? Nikon 35mm f/1.8, Nikon 50mm f1.8 or Macro 40mm?
I know 40mm one is a macro one…
Just wondering which lens would be the sharpest for day to day work…
What are the disadvantages of using macro 40mm for day to day work? ALso is it DX or FX?
I know 50mm is FX
and 35mm is DX
Define "sharpest"…
Also, I wonder if you understand the difference between DX and FX

Most lens sizes come in both, depending on where you want the maximum sensitivity (I prefer FX lenses, but that. A personal choice). Look at the fill name of the lens -- if it has DX in it, then it's a DX lens; if FX then it's an FX lense
'Macro' lenses essentially allow you to get a 1:1 ration between image and object, usually at the focal distance, so it depends on what you are doing for "day to day work". Most of the time, unless you have a very large number of 1:1 image close-ups, the macro feature makes no difference.
In general, macro lenses are going to provide the highest resolution images.
All three lenses are going to be very sharp when you use an aperture that is two stops down from wide open
The depth of field is going to be shallower, the longer the focal length of the lens at any given lens aperture, so apparent sharpness may appear different from lens to lens under the same lighting conditions.
The macro would be the sharpest for extreme close-ups, such as insects or postage stamps.
Otherwise it would depend on your conditions of use, chiefly the aperture (f-number) in use. All of those lenses will give sharp pictures if used well. Note, of course, that they all have somewhat different angles of view.
I assume that you would be using them on a DX (crop-frame) camera body.
They are all very close as can be seen by going to photozone.de. Photozone.de provides numerical values in their sharpness chart making it possible to now only know which lens is sharpest, but also by how much. Why spend $100 for a 3% increase?
The depth of field with a lens is not a straight line - it's curved which is why corners are not as sharp as the center. Not so with macro lenses which have a nearly perfectly flat depth of field. This will provide sharper corner sharpness. Of course, you can see if this is true or not by looking at the sharpness charts at photozone.de
