Generally, some of the advantages of the Panasonic DMC-GF1 compared to entry-level DSLR competitors include: it has slightly more focus points (23 vs 11), is much smaller (mid size (119×71×36 mm) vs prosumer size (124×92×85 mm)), is slightly less expensive ($899.99 vs $1,195.00), is thinner (1.4" vs 3.3") and is significantly lighter (330 g vs 598 g).
However, on average it records lower quality movies (720p @ 30fps vs 1080p @ 30fps), has a much lower resolution screen (460k dots vs 1,040k dots), doesn't have image stabilization (none vs sensor shift), takes much lower resolution photos (12 MP vs 17.9 MP) and doesn't record movies in 24p.
