I really need some more focal length in my photography bag. And I cant afford a 300,400,500 OR a 600mm lens! Im a very poor guy. So I thinking of getting a Nikon TC 1,7 so my Nikon 70-200 2.8 VR becomes 340mm. Which I hope, will help me to get some hard to reach shots. The only thing that concerns me is the loss of quality and AF. I have read some posts where they say its sucks to use a TC, the quailty of the image is very bad, and its impossible to get focus, with Autofocus. I dont want to be one of them. I want to have sharp images, and Good AF. So. I would LOVE to know how many here thinks its sucks to use a TC with the 70-200 VR lens. I would also like to see some review, if there are any that tests 70-200VR woth 1,7TC. One more question. I also have a Nikon 105 VR bug lens. Will I get more Magnification then 1:1 when using a TC with it? AND more working distance? I would love to hear both negativ and positive comments about 1,7 TC with 70-200 VR, and 105 VR bug lens. Or should I sell my car and get a 400 2,8 instead?? Nah. I like my car.
