The Minolta Dimage 7, 7i, 7Hi series is a "pro-sumer" line of digital electronic viewfinder cameras from Minolta. These are also known as bridge digital cameras. They are capable of capturing images in the 5-megapixel range.

The Dimage 7 was announced 11 February 2001.[1] The line uses a 2588 × 1960 pixel sensor coupled with a permanently attached optical 28–200 mm (35 mm equivalent) f/2.8W – f/3.5T zoom lens with a macro switch (16 elements in 13 groups, includes two AD glass elements and two aspheric elements)
The Dimage 7/7i/7Hi series cameras were powered with four AA batteries, which discharged quickly; the 7-series was replaced by the DiMAGE A1 in July 2003.
