24-120mm Nikon VR Consistancy

In using my 24-120mm over several days, I find that do have more shots that look “soft”. But most are sharp and plenty contrasty.

Once I started getting this feedback, I began to realize that I’ve been trying to push the lens past its limits. I try hand holding the lens zoomed out to 120mm and using shutter speeds of 1/4 second. It’s amazing how good some of these images actually are.

I also find that many images have shallower depth of field than I expect. I presume that it’s partly due to having been shooting with my 24mm for so long that I forget that at 80mm and f/5.6 the front and side of a tree trunk won’t both be in perfect focus. Moving up close with the 24 mm and it’s floating CRC element gives a different rendering regarding front to back focus.

So I need to be more conservative in what I ask the VR in the lens to do. And I need to gain an intuitive feel for DOF across the 5x zoom of the lens.

I became fascinated with how people actually make decisions based on the science of decision theory and emerging understanding of how the brain works to make decisions. My passion now is this deep explanation of what has been the realm of philosophy, psychology and self help but is now understood as brain function. By understanding our brains, I believe we can become happier, more successful people.
