I recently made the switch from scanners (Nikon Coolpix 9000) to using a digital camera to scan slides, transparencies and negatives. After watching a number of youtube videos and some lens tests, I've decided it's time to throw the scanners away. For 35mm slides, 120 medium format and 4x5 transparencies, I'm now using a Fuji GFX100, a Pentax Macro lens and a 5K light table. With this you can make 16bit B&W Tif files.
The results so far have been incredible, with fantastic shadow detail and resolution. I'm getting at least 2400PPI, but for 35mm and 120 medium format its more in the range of 4000ppi +.
I'm wondering if others have also started to make the transition to shooting film with digital to digitize slides and negatives.
