thanks for the input John_T, since the softness is occuring in all three lens, I'd have to agree.... but it occurs to me that I wonder if the UV filter is effecting this too...
Did you do any post processing on your image?
with some post process, I can get it close (I think)....
Agreed, hardly a qualitative difference between your shots. There is a muddiness in the colors and contrast too which is likely the camera.
The sharpening you did doesn't appear to have done much more that give you artifacts and the illusion that it is sharper, typical of when there isn't much there to sharpen in the original.
Depending on the quality of your UV filter, it will affect your images in two ways, one, reflections on and in the filter, and two, altering your colors. I don't use a UV filter at all, except maybe on hazy days. The lens shade and reasonable handling is more than adequate protection for a lens, so I find no merit for a UV filter on that score. Try the same shots without the filter.
The dragonfly shot is just any old shot I grabbed with no processing other than crop and jpeg cut down for the 100k limit. It is a 100% crop.
