I normally scan 35mm at 3200dpi and medium format at 2400dpi. The scanner has a higher optical scanning ability, I believe, but I keep it at those resolutions just to keep file sizes manageable.
That means a 6x4.5 MF image comes in at around 20MP, a 6x6 at around 26MP, and a 35mm image is around 14MP. They could all go higher, but since I'm mainly just putting them on the web there's no real point in it.
I've never had a problem with artifacts, but that could just be a matter of my own lack of powers of observation. Somebody else might look at them and spot something.
I do use it for both negatives and slides, and the software that ships with the scanner works quite well, although more slowly than interfacing with a third-party application such as VueScan.
