It seems that the Afs 300mmf4 will autofocus with new tc17e II.
Wow, 1.52 from D70 + 1.7 from tc17eII + Afs 300mm/f = 775mm at around f6.
Quote from B&H :
NOTE: Due to the high-quality design of this converter (7 elements/4 groups), the teleconverter will only fit and work with a select range of lenses, but with limitations. Only the following lenses are compatible:
AF-S 300mm f/2.8D ED-IF (II)
AF-S 300mm f/4D ED-IF
AF-S 400mm f/2.8D ED-IF (II)
AF-S 500mm f/4D ED-IF (II)
AF-S 600mm f/4D ED-IF (II)
AF-S 70-200mm f/2.8G ED-IF VR
AF-S 200mm f/2G IF-ED VR
AF-S 80-200mm f/2.8D ED-IF
NOTE: Autofocusing only possible when used with D1, D1X, D1H, D2H, D100, F5, F100, N90s, N80, N75 and N65 AF SLR Cameras (or any newer models).
Note: Only limited AF with AF-S 500mm f/4D ED-IF (II) and AF-S 600mm f/4D ED-IF (II).
And from another supplier :
I do not have a TC17e II in stock. I can order from Nikon, but it might take a very long time to get it. Nikon is very slow in shipping. It might take a month to get it, or it might take 4 months to get it, I do not know.
TC17e II will autofocus with any autofocus lens.
But to be safe better bring your Afs 300mm/f4 down to try before buying.
Note : Checked with cathay & they have no idea when new stock will arrive.
