Hi all, I recently went on holidays to the UK and when I returned I downloaded all my pics and the majority were fine. Except the images I took around water as I like to have the feathered look especially when there is a waterfall. I took around 30 images in two separate locations spanning several weeks, used the same lens & tripod. Out of the 30 feathered images only one or two worked, the rest were partially blurred. Ive done this numerous times over many years and this is the first time this is happened. I'm hoping someone with more knowledge than me will shed some light on this disappointing issue. The only changes between this time and others was I purchased a new lens. My camera is old but still working fine, unless this is the first indication of it going bad. Its a Nikon D70S Any help or suggestions would be appreciated.
