Just before Christmas I sold my D90 for a good prize and bought a D7000 as replacement. The advantage being that I now could use all my old Nikkor lenses as well. Well, TBH, all the AI's have been sold now (except for the Kiron macro) and I bought some new lenses (AF D and AFS).
So far with the dogs I have tried the 18-200mm (already had this one, but good for action), the 12-24mm and the 50mm.
Results are really different each time and it is fun to go out with the limitation of just one lens (in the case of the 12-24mm and the 50mm; the 18-200mm just covers it all) and look at the differences afterwards. Especially Bokeh is very different and I find the 50mm does this best. Almost like a watercolor.
Here are some examples:
This the 18-200mm at 200mm uncropped (just lucky with the framing this time). ISO 100, F5.6 at 1/400sec.
Second one:
This is the 12-24mm at 12mm, uncropped. ISO 5000, F9 at 1/320sec and -1/3 EV. Vivid colors.
Same lens. At 12mm uncropped, ISO 5000, F9 at 1/6400sec and -1/3EV. If you wonder about the colors, I was experimenting with Vivid mode in camera. This is a bit too strong, but it is fun to use now and then.
And finally:
This is the 50mm F1.8. Uncropped at ISO 1600, 1/250sec and F5. I like the bokeh here and although the head is blurry , the nose is sharp (is that the point of rotation when they shake?). Great focusing with this D lens.
Same lens. Uncropped at ISO 1600, 1/250sec and F5.
And one from inside the house, without flash (love the light of this lens.
50mm again. Uncropped at ISO 6400, F2 and 1/100sec.
The 18-200mm is the easiest to use of course. Close focusing is possible and it covers all lengths with one turn of the hand. Quality wise I like the 50mm best. Very sharp, good bokeh, but doesn't focus as close as the other two lenses.
Finally the 12-24. The sharpness is less evident is these pictures, but it is good. Bokeh is almost non-existent. This lens is great fun if you get really close (10cm or less) to your subject.
Would like to here any comments.
