Top Amazon Reviews


  • Best corrector for the quattro
If you have a Quattro. This is the coma corrector you want. Its not designed expressly for a range of focal ratios (though it will work), its designed for your f/4. Perfectly round stars all the way to edge of frame, though I did have to dial in the back focus first.
