Congratulations on your purchase. I had an S2a for years and got excellent results. The Nikon optics that are available with this camera are very nice.
The one caution would be the 1/40th second sync. I sued mine regularly on a tripod, with or without flash. Even though faster speeds (e.g. 1/250th) are possible, due to the slow sync, handheld can lead to some distortion.
I had to sell mine, because my aging eyesight interfered with focusing. I currently have an RB67 with a diopter corrections in both my waste-level finder and my prism.
