Owner reviews: Cosina AF MC 75-200 mm f /4.5 Macro
Wide open is sharp lens , internal focus , cheap for day lights photography not bad .
The start aperture f4.5 , the focusing motor is noisy and slow , personal i dont use it .
if you love manual focus lens and you wanna be sure you have one sharp lens for about 10$ it can be one option .
