The problem I have with answering that is I do not own the 600 so I can not know.
But it does a really good job. I did quit a bit of research before I bought it. I am archiving my old family photos and wanted to do the best I could do.
What was impressive is I have quit a few small pictures, like 2" x 2" that were probably contact pictures from the negative.
I haven't had time to mess with it since April. I have the supplies and equipment to do wet scans and I am going to go back and scan all of the old negatives. I have the negatives from family photos going back to the 30s.
