Manual Focus is available for use when autofocus or focus lock is not desired. It is possible to use the focus ring for focusing just like an SLR camera. It is also possible to magnify the display to ensure precise focusing.
Dpreview則是寫"The SD1 DSLR will now be know as the SD1 Merrill, in honor of the Dick Merrill, inventor of the Foveon sensor technology on which it is based. The price will also be revised, falling to what should be a street price of around $2,299, which Yamaki attributes to work conducted to reduce production costs of the sensor. Despite these changes, his letter promises the performance and characteristics of the sensor have not changed. To avoid disappointing existing SD1 customers, Sigma will offer a support program with 'points' that can be exchanged for Sigma products.
($2,299 is the Minimum Advertised Price quoted by the Sigma Corporation of America - the price that suppliers agree not to publicly advertise the camera below - and can be expected to be the street price shortly after cameras become available)"
