Actually, a good product should simply be further developed and the new lenses should be fair with my Nikon 200-500 pump the focus so dermassen that an adjustment was not possible. and I therefore unfortunately sent back again.
Pro
Contra
The problem here is probably not so much the long focal length, but rather the limited amount of light that this lens already processes, with a maximum aperture of 5.6. With a converter, the best that remains is an 8.0, which is very little that the AF can still work with. In general, a teleconverter always results in a loss of quality, so the lens has to be very good to have enough left over.
Accordingly, the reviews are much better when using better lenses like the 70-200/f2.8.
