medium format is just like 35mm..just that you get more film coverage and detail on the negs...u can get a holga for a start..or the seagull...for b/w i suggest using kodak tri-x 400..and perhaps you want to start shooting fuji E-6 slide film first..the velvia 100 is good for shooting landscapes..if u want portraits..u might want to try astia...slide is also cheaper
