I leave Yellowstone in a few weeks so I've been practicing with my 60mm lens. I am not able to produce sharp images, some are better than others, and I don't know why. The attached image is the best of four. It is not sharp; see the 'halo' on the side of the bolt? This shows me that I am not getting a sharp image or at the least there is an error somewhere. Or am I expecting too much? With reference to the scale shown on this screen capture on ViewNX, this image is 1:1.
Gitzo 3530 tripod with a RRS pano base with a RRS long lens support package. Nikon D3s Nikon 600mm lens Focus Mode: AF-S AF Area Mode: Single Shutter Release Delay: ON 1/500; f/6.3, ISO 400 Spot metered. I am rolling my finger over the shutter release My hand is resting on top of the lens I am pausing for a moment before rolling my finger over the shutter release.
What I am I missing? I see images posted here of birds in flight that are tack sharp and I can't get a bolt on a swing-set sharp. At this rate I'll come back from Yellowstone with no sharp images. If that happens, my gear goes up for sale and will find a new hobby.
