alpha - go for kenko, the 1.4x is quite good as I've heard (and it's cheaper than Nikon one)
This One? (It works with AF-D lenses, right?)
Thanks a bunch adamz :^)
New products - The 300 2.8 and 2X Teleconverter rumour is true.

They talked about delivering for the Olympics and it certainly seemed like they did. Makes me wish I were a sports photographer with means. I'm still looking for a trust fund btw...
I wouldn't be surprised if the images from this Olympics are unprecedented. The Nikon gear shivaswrath mentioned makes new things possible. It will be exciting to see.

Here's just a curious question. Unless I'm mistaken, with a 2x teleconverter, you increase the image circle area by a factor of 4 (hence, 2 stops of light lost). My question, then, is whether you can put the TC on a DX lens like the 85 3.5 macro, which does 1:1 macro reproduction, and get bigger than 1:1 on an FX camera. Does anyone know if that's possible? Or does the TC also affect the minimum focus distance? Just wondering.

They don't affect the closest focusing distance. I think.

They don't recommend the TC's on their macros at all.

The new TC does list the 105/2.8 VR lens as compatible, but without autofocus.

That's true, but a TC will multiply the reproduction ratio of a lens that they do recommend the TC on.Yup it does.. but its better to use extention tubes with macro lenses as that way you don't introduce image degradation that the TC does. A 2xTC doubles the faults of the base lense in most cases.

TC magnify the macro's flaws in the same amount as the Extension tube at the same reproduction, but with a TC you add the flaws of the TC's optics on top of that, and you lose more light through the TC's glass (but you get extra working distance compared to extension tubes). Extension tubes are preferable in most cases, but there's nothing wrong with using a TC if you need the extra working distance. Nikon even used to recommend using the TC-201 (or was it the TC-301?) with the 200mm f/4 AI-S Micro to get it to 1:1.

Yes it does work on the AF-D lenses. I use this exact combination occasionally. However, you will notice a loss of sharpness, sometimes a lot! Also, your metering will get a little screwy, especially if you're one who likes to use matrix or spot metering. Stick with center weighted. Also, exif data is not updated. When I use the kenko 1.4 or 1.5 (don't ask why they made a 1.5 lol) it still says 300mm. Here's a shot I did with my 300mm and 1.4:

Like I said there's some trickiness to it but it can work. You will just need to spend a bit more time PP then without it.

alpha - yup, that's the one
as for using TC - TC20 is extreme, but there are also the TC17 and TC14, and as far as TC17 it doesn't affect IQ too much (acceptable level), as for macro work, I've been using TC17 with extension tubes on 70-200/VRI and it works very nicely - the image is bigger :) (that's obvious) and the focus distance is not changing (due to TC17) - would like to try it with the 105VR

Thanks for the help hearty, Gentoo, and adamz :^)
How troublesome do you find the combo Gentoo? Hearty, do you have similar problems with it?
Do you think it would be worth it to get the Kenko TC maybe next year, or wait a few years until I've got that AF-S version and get the real NIkon TC?
