ingrid, you can't use the lenses from the s3 on a dslr, full stop. The lenses for the s3 are a screw in type. I made the mistake of buying both lenses, and then getting a dslr. If you are in any way semi serious about photography, and want to get better etc, save the money you would spend on the s3 lenses, and use that towards a dslr. I can't believe how much difference it made to my photography! Also, different dslr lenses have different filter threads. One of mine takes the 52mm, the other a 58 and also a 77! Bottom line, how much are you prepared to spend for your hoby? example, canon 400d, aprox $1200 body only, add about $400 for kit lenses, or get the lenses you want seperately, which is what i did. My initial outlay was $3000, but you don't have to spend that sort of money. Your 2 lenses for the s3 and tube will put you back somewhere near $500 anyway. I'd put that towards a dslr, the wide angle does not make that much a difference, but the wide angle on the dslr sure does!! Same for the tele!
