If you want to see some results from Ektar 100 in medium format, I posted some scans of my Ektar 100 work in my gallery here - shot with a 1956 Rolleiflex that has damage to the coating on the taking lens. The photos were taken at twilight, with multiple light sources in the frame.

No sharpening or other filters applied - this is just a straight scan, with minimal exposure correction to get it where I wanted it. Scanned at 2400 dpi on an Epson V750, then re-sampled down to 72 dpi for web use.

Here's another from the same location. Details are the same - I just burned in the sky a bit.
