That might depend on what type of budget and birds you're talkingabout. The basic mantra of most bird shooters is "More length! Morelength!" Some people here, such as Raymond Barlow, are big advocatesof the Nikon 200-400; but, you're talking $5000.00. Others recommendthe 300 f/2.8 with TC, but again, an expensive proposition...

Yep that indeed would be the context of a "teleconverter"..

They are available as 1.4X, 2X, or 3X..

IF you put the 2X on the 300mm f/f2.8 .... the result is 600mm at about f/5.6..

So notice that while the focal-length was doubled ... you lost lens speed, and thus need a longer shutter speed. (you also lost resolution).

So it is a CHEAP(er) entry towards a longer lens .... but not always practical because of the loss of light, and loss of resolution..

(not to mention the loss of "resolution" resulting from camera shake resulting from a longer shutter speed).

Thanks for reading .... JoePhoto.
