You may recall my stating that I recommend 3 times focal length of lens as minimum shutter speed for hand-held shots-And many here argued, quoting shutter speed=reciprocal of focal length, was right-(Although there is no trace of the origin of this formula) Well I was going through my photography library at home,the other day,and here it is-straight from the Master-Ansel Adams-a quote from his book, "The Camera." (Published by Little,Brown & Company 1980) page 116:

" A test I conducted some years ago,photographing leafless trees against a sky, indicated that, using a normal, (50mm) lens on a hand-held camera-The slowest shutter speed that ensured maximum sharpness was 1/250th sec." So he recommended 5 times lens focal length as minimum shutter speed for maximum sharpness hand held.

Are you going to argue that Ansel Adams got it wrong? regards, Ken
