My lens when I turn it all the way to the right should be focused well at infinity, but I have to turn it back about 2mm for it to be completely sharp. Is this normal, or do I need to get it repaired. Thanks
check if your other lenses work as you expect them to.It may not be the lens but the focus screen in your camera that needs an adjustment. this was the case with my Mamiya 6.anywaymy newAF50f/1.4 does focus at infinity at the infinity markAS ONE WOULD EXPECT.
