I really only used these TC on the 300mm f2.8 AFS and 400mm f2.8 AFS.
Now I have the 200-500mm f5.6 AFS VR I dont really need them with the zooms where they degrade quality.
I have the following lenses all covering FX sensor - Sigma 12-24mm f4.5-5.6 HSM (AFS), Nikon 24-70mm f2.8 AFS, 70-200 f2.8 AFS VR and 200-500mm AFS VR so I am covered for the 12-500mm range with zooms.
Or I can use AFD primes that step from 14mm f2.8, 20mm f2.8, 50mm f1.4, 105mm f2.8 AFS VR, and 300mm f2.8 AFS or the 400mm f2.8 AFS so I still always end up with a f5.6 lens if I use the x2 TC.
At 600mm and 800mm focal lengths it is difficult to track wildlife if it is fast moving even when tripod mounted with a Wimberley gimbal. Also I tend to prefer to manual focus at these focal lengths.
When you then stick these lenses on an APSC sensored camera there is a further x1.5 apparent focal length increase. So essentially I am covered from 12-1200mm depending on camera body and lens combination.
This covers all my needs!
When you then add in a 21-24MP sensor either FX or DX you should have enough pixels to crop very adequately without appreciable image quality loss.
