Hi anyone ever compare the image quality of the Leica Apo extenders to the non Apo version or other brand extenders? Thanks Dennis
The APO extenders are superb. They do degrade the image quality, but it is by quite a small amount. They are completely usable, however and they provide a great addition to the kit. These two photos are both taken with the 180/2.8 APO and the 2x APO converter. I have not used other converters that maintain the image quality as well. Here is a 100% crop from the second. I believe this was around f/4 on the lens (so f/8 overall) I believe that is also without sharpening.
