Title: Excellent 1.4X tele converter
Review: I used this 1.4X TC for 135mm f/2L lens. The lens + 1.4X TC becomes a 189mm f/2.8 lens, which is excellent! Raw Image quality out of the camera is already very good, only slightly softer than the 135mm raw image. Post processing easily corrects that softness.Hightly recommended!
