I dont have a x1.4 or x1.7 teleconverters, only the x2 and x3 Kenko DG 300 Pro units.
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.
That's true for fast moving subjects ...but 800mm lenses are often used in many wildlife situations.
This was 500mm with kenko 1.4 on D300 ....1050mm.....
