What's the difference between Fuji SLR cameras S3 and S2?

S3 is an upgraded product of S2. S2 doesn't have a Chinese menu, but S3 does. S3 has higher pixels than S2. At that time, or these two modes were the main modes of photo studio or photography studio. However, these two machines are too old now. S2 and Canon 10D are almost products of the same era. Now the Canon series has been published for 80 days. S3 is about the same as 20D or 30D. There is an S5 in the back, which was also a good opportunity at that time.
