I took this shot today while on break at work (yeah I even take my camera on break). This is the original only cropped and saved for the web. The lens in question is a Nikkor AF 70-210 f4-5.6. Shot with Nikkon D100, settings - RAW, Exposure Auto, 1/1250 @ f8, Exposure Comp: 0-EV, ISO 800, WB Auto, sRGB, Sharpening Low, Noise Reduction Off Magick Michael

This is the PS'd version. Niether seems to be sharp. I have tried everything I can find and this is one of the best shots I have gotten with this lens. Help! If it is my lens, anyone have any suggestions on a replacement? Keep in mind I am poor (again).

So many possibilities for fuzziness... With in camera sharpening "low", did you then do any sharpening within PS?

Yeah, hard to say Michael..... I'm certainly no expert on lenses..... One idea that did just pop into mind was the choice of ISO at 800..... There is a lot of grain in the sky areas (which really can happen at any ISO) but I'm wondering if that choice of 800 introduced so much grain that you cannot get the bird sharp because of it. Took your original and tried sharpening it up a bit but I'm not sure if there is a noticable difference between this and the second postworked version?

I am, therefore I create.......

Did you have the AF set to servo or single shot? It is very hard to catch a bird in flight in low light. I have had my best results in bright day light sun to my back shooting high speed 1/1000 or faster like you did f 9-11 with the AF set to servo. Even with these settings 1/2 of the shots are soft.

Hmmm ... really can't say with that shot to really tell. Kind of a tough shot all around. After cleaning the grain up a little and then sharpening it, I think it is a bit softer than I'd expect from a D100. I'd still like to see it with a little better subject. -=>Donald

Not sure it is a good comparison to sharpen a jpeg... But the results so far indicate that some more photoshop sharpening on the original image should help quite a bit. Digital sharpening is always needed; it does not indicate any fault of the lens.
