This is the crop without Smart Deblur, about 100%

Unfortunately it won't. :banghead:


What aperture and shutter speed were you using? The image appears to have had the EXIF data removed so unfortunately I can't tell for myself.

If you had taken that same image with a Nikkor 180mm f2.8 or a Nikkor 105mm f2.5 the image would be very different and we would be discussing how sharp it was.

Zoom lenses and ultimate sharpness do not tend to come in the same box. I venture to suggest the sensor can out-resolve your lens.

I am assuming it's hand held, the finial on the church has much detail and is against the bright sky. I would say that is as good an image as you can expect under those conditions. The definition of fine, backlit objects is very dependent on aperture and exposure, small changes in aperture make a big difference to the captured image, because the subject/background contrast is extreme.

http://www.naturfotograf.com/lens_zoom_01.html#AF24-120

Notice that Bj¸rn's tests were made with a D1X and D1H with no more than 5Mp and DX, I suspect he would need to revise his conclusions for an FX 24Mp camera.

If you can get A3 prints which are satisfactory when viewed from 1.5 times the diagonal than I would be very happy, zooming in in the minutia on the screen is pointless unless you intend to make extreme crops or print wall size images. And even then I am sure when viewed from 1.5 times the diagonal it will be tack sharp.

It was taken with a Nikkor 24-120 f/3,5 on auto focus at 110 mm and 1/350sec. at f/8 with my D600. The church was at infinity. The crop of the steeple shows my infinity focus concern and the same crop after a quick run through with SmartDeblur, a new program I've been trying out. It must be remembered that these concerns are only for large prints or extreme crops, as this technical quality of picture could be easily hung as a Super B 1(3x19 inches) with minimal post processing.
What point/object did you use to focus in the shot?
How far away from you is the church?
Whats the detail like in the car (right mid distance next to lamp post) registration plate when similarly cropped?

I was set at 11 auto focus points locked in the center with center weighted metering of 15. Iso 200 1/350sec f/8 110mm Nikkor 24/120 f/3.5-5.6G with VR on.

I think this plate crop is at 100%. I would estimate the distance at about 100 meters to the church.


The full pix that I posted had the EXIF data included but SmartDeblur seems to remove it on the crops.


Interesting, I just downloaded my pic and it had the EXIF removed. Is this normal or did I slip up?

Need to take the same picture with camera on a tripod.

I dont have that lens but the lens can also make a big difference.

I used to be able to hand hold at 1/20 with a 200mm but now it is not the case. Digital is much less tolerant (sharper) than film. At 24MP the camera is much much better than film ever was even Kodachrome 25.

Next time I'm out that way I'll use a tripod, do the mirror lockup and remote release, and also take my 70-200 2.8 VR Sigma and compare the lenses.

Given the lens data you posted (Thanks) I feel it simply the sensor out resolving the lens.

I don't see camera shake in that image.

I will post a JPEG later to see if the forum software strips the EXIF data but the image size data survived? o.O

An image I took earlier this year walking the boys to school one morning:

JPEG with the EXIF intact when it left me.
