The first interchangeable-lens DSLR following ES-LV capabilities of Canon's Powershot G1 (maybe, Canon Powershot Pro70) was in early 2005 with the Canon EOS 20Da, a special version of the Canon EOS 20D with exposure simulation live view modifications for astrophotography, which included a similar focus preview feature, plus first ever for any DSLR the new exposure simulation live view allowed capture of star exposures to selectable brighness 'effects' (Canon ExpSim LV). The first general-use interchangeable-lens DSLRs with live view for both exposure simulated live preview (ExpSim LV) and framing livepreview were the Canon 20Da of 2005, followed by Canon EOS 1Ds Mark III and Canon EOS 40D of 2007. The first general-use interchangeable-lens DSLR with live view for framing preview only like most fixed lens digicams was the Olympus E-330 of 2006.
