"Re: D7000 soft?" Wed 06-Apr-11 11:24 AM by billgreen
I guess I'm left scratching my head over all the discussion about the D7000 and soft images. Last weekend I took this image of the flag on a windy day. While there is nothing outstanding about the image I did notice while processing that it is ultra sharp. It may be hard to appreciate at this size but at 1:1 (after being cropped by 33%) the stitching is clearly and sharply visible between the stripes. I used minimal capture sharpening and minimal processing. This image is anything but soft. So for those thinking about buying a D7K and are worried about it being soft, in my view there is simply nothing to fear.

Bill, It appears that your shutter speed tells the tale. I have noticed that the d7k can be used for static objects in any form you like, yet with moving objects or shooting free hand you need a faster shutter speed. Experiment with your 7000 to find out just how slow a shutter speed you can shoot and still achieve quality images. Don

A starting point for shutter speed for hand held images with a DX sensor is 1 / (focal length * 1.5). This approach comes from the 35mm film cameras that used 1 / focal length of the lens.
The above also assumes good hand holding technique, breath control, and gently squeezing the shutter release.
After that as Len has mentioned DOF has a big impact. And sharpness with respect to DOF has a number of subjective decisions like the viewing distance and what one considers acceptable focus. One also has to be careful about the size of the aperture, as any f stop over about f/11 can add diffraction to the image. This diffraction arises from the small opening acting like a lens.
And then there can be issues caused by filters.
Some Exif reader used with lenses that register focused distance, one can even be provided with the DOF values for the image since the focal length, f stop, and focused distance are all recorded, and the CoC (Circle of Confusion) for the camera model is known.

In response to reply 1 the OP was about how sharp the image was. Sharp images are often at least as much about enough depth of field and a fast enough shutter speed as the sensor. I would expect 72mm on DX at 1/2500 to be a good combination to show what a D7000 can do even with a moving flag - the OP confirms a very good result.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
