[QUOTE="RocketCowboy, post: 476735, member: 25095"] Like [MENTION=31330]J-see[/MENTION] said, while jumping up to a 2x teleconverter sounds great ... that 70-300 is now a 140-600, the light that the lens lets in is also decreased to the point that autofocus no longer works. Image quality also suffer as a result of lower light and being an independent design (it's not designed considering all the specific design elements of your given lens). Consequently, in many cases you'll see a compromise with the 1.4 or 1.7x TC instead of the 2x. [/QUOTE]
