 The lesser Autogain Framing/Focus Live preview, borrowed from framing/focus autogain live view digicams, in lesser autogain live view DSLRs does not typically serve as their principal means of framing and previewing before taking a photograph, with this function still being mainly performed with optical viewfinder.The first interchangeable-lens DSLR to feature framing live preview was the 2004 Fujifilm FinePix S3 Pro.While initially largely a novelty feature, framing/focus only live-preview functionality from digicam framing/focus live view has become more common on DSLR cameras, and almost all new DSLRs have had the feature since mid-2008.
