New book on Sigma Lenses


There is a new book from Ammonite press by Andy Stansfield called 'Sigma Lenses The Expanded Guide'. It contains 231 pages on Sigma lenses (mostly current, but there are some new ones that did not make it in, such as the 50-500mm OS version). There are MTF charts and a brief analysis (highlights) on each lens with examples. The book retails for 19.95USD or 14.99English Pounds (it is available from Barnes and Noble on-line at further discount).

I would say it is worth the price.
