So I'm not sure if this is buyer's remorse but I literally purchased the 60mm f2.8 for macro stuff and general walk-around. The min focusing distance was a big advantage for me over my 50mm 1.8 for food and general exploration around town.
The 60mm 2.8G is quite nice, an excellent lens!
Now I hear about the 20mm f1.8 and it also claims a 7.x" min focusing distance. Should I just return the 60mm and go for the 20mm?
No! At MFD, (minimum focusing distance,) these two lenses will "see" a vastly different image! An ultra-wide angle lens helps the shooter compose interesting images, by having something of interest in the foreground, in focus, along with objects in the background being in fairly clear focus. (These can be reversed, of course.) Or, a fairly close subject, and the background, can both be in sharp focus. This is possible because ultra-wide lenses have such deep depth of field. (All else being equal, longer-focal-length lenses have progressively shallower depth-of-field.)
Planning on getting an FX body in the future but am shooting DX now.
A 20mm lens is ultra-wide on FX, and on the wide side of normal on DX, an a 30mm-equivalent angle of view.
A 20mm lens has, if I remember correctly, a 70-degree angle of view on DX, and 94-degrees on FX. If you have a kit lens that starts at 18mm, you can test the 20mm focal length, and see if you like it on DX. This new 20mm 1.8G should have less distortion along the borders than your kit lens at 20mm, though how much less remains to be seen, when reviews and images are posted.
