The S3/S5 sensor was one of the best crop sensors ever, it thrashed the pants off the Nikon 10mp sensor in the D200. I had an S3 and if it was not for the blinding price I got a Canon 5d for would still be using it. I only used 2 lenses on her though a Sigma 18-55 2.8 and a Tokina 24-200 for the very rare time I wanted longer, I loved the results with the former. Great call if you have some nice Nikon glass, I wish they made a full frame version of her.
