Sorry K-H, really don't want to let you down here ...
But how or when do you qualify an image as 'tack sharp' ?
Thanks Bart for asking. You be the judge for your images.
I don't want this to be a thread for arguing about whether an image is tack sharp or not. There is already such a thread on FM.
My own criteria are pretty simple. Most of my images are not tack sharp.
I know it when I see it, whether shot with Canon, Fuji, Leica, MFT, Nikon, Sony or any other brand of camera. That's why I placed this thread in the brand agnostic part of the forum.
But a few of my images don't show any subject movement fuzziness and the intended focus area is sharp with other areas OOF due to a narrow DOF used. I also consider the lens being used to be capable of delivering in principle sharp images pretty much from center to edges as most Pro lenses do.
How is this for a description of what I was thinking?
Please, let's have some fun and not get too scientific about this.
