i borrowed my fren's tamron 18-270mm and i compare to my 55-200.. 270mm and 200mm seems to be same also...
if you need range longer than 420 (which usually do), 300 f2.8 with a 2x TC is probably the lightest you can go and get away with sharp images with a resonable fast focusing (which is useful). Try getting AFS ver II, it is only 2.6kg and with a 2x TC just under 3kg.
TS states that he can only go 2kg... but whether that includes the bags to carry all the lenses, he never specified... Or he would just go without the bags and all... I doubt he can carry 300+TC III without putting a heavy strain on his back.. not to mention adding the body will hit somewhere close to 4kg! And if I'm not wrong... more birders would carry a tripod/monopod to assist weighty lenses, which of course will add to even more kgs!
How far where you focussing?
Most of these zooms breathe when focussed close.
Strongly recommend Nikon 300mm f4 plus 1.4 tc ( kenko will do) . Previously I was having sigma 150-500 OS . After testing out the Nikon 300mm f4 with 1.4 tc . It was very diff in contrast and IQ! Very surprising is sigma at 500 mm and Nikon with 1.4 tc at 420mm got no diff in picture size! Comparing bokeh, Nikon 300 f4 is amazing! Check out my photo to see the iq as got both len picture . http://www.flickr.com/photos/50237629@N08/
You might also want to see if you're fine with the IQ if using 1.4x and 1.7x TC with your 70-300mm.
The aperture would be quite horrible, but not much worse than the sigma 150-500mm.
Nikon TCs won't work, so you might want to check Kenko or other third party.

Thanks fmeeran, but me understood TC will not work with 70-300 VR lens, hv you come across other band that will work?
Since most of the time I use F8....so it ok if it work and I can save 2K+ with same IQ .
@ Ckianh2000
So nice that you have the same cam body as me, it's a straight forward.
Thanks alot, have seen your photo....IQ really beat my Sigma 120-400mm "hands down".
BTW did you use a tripot or shoot handheld ? cos it's not light either.
I have got quote for both but SLR do not carry NIKON.
Price yesterday : Nikon 300/F4 = $2087, TC-14 eII =$ 610
Where it you bought yours, understand TC14 has ran out of stock here.
Thanks

chrisxtremes said:I'd say get a monopod and it can be a walking stick for u. wanna shoot, turn the stick to stabilize your cam.
I'm a no pro here, but isn't shooting birds should use a bigger aperture to capture max dof. Let's say with the tree and stuff, maybe an f/5.6 or sth? This way will have faster shutter and decrease blur = sharper picture. Please correct me if I'm wrong as I've never shot birds before and I wanna learn from the pros here![]()
Sorry....sorry.....I clarify
2kg for my cam body + lens alone ( I can managed)
My streetwalker pro = 1kg
My SIRUI T2205X = 1kg
+ a bottle of water+ flash
all in all = 5kg maximum ( for short walkin distance) as most of the time I don't carry tripot and flash.
Thanks lol.

I am using the D7k with AFS 300mm F4 plus 1.7TC to get 500mm F6.7. There are many reviews that this combo has IQ degradation but I am satisfied with it so far. I choose this setup after finding some reviews of users successfully getting good results. The only downside for this combo is slow AF and hunting in low light. The following link shows an example of some pictures taken with this combo.

I also have the kenko 1.4TC which I used when the need for faster AF arises, e.g. BIF. There is little/no difference in IQ between the 300mm F4 or the 300mm F4 with 1.4TC.
Hope this helps.
The Kenko 1.4x TC "does" work with the Nikon 70-300mm VR but IQ is not OK and AF is next to terrible. I would not recommend this combo.
