I was trying to shoot a kid's soccer game and found myself wanting a little more reach than the 300mm I was holding.

I'm wanting to get a teleconverter, but remember seeing some rationale for going for a specific manufacturer, but can't remember which one or why.

Any suggestions?

Thanks

The sigma TC's work best with the Sigma lenses. I'm not sure if the Nikon one will work.
1.4 is quite sharp, and the 2.0 is a bit soft, but better than nothing if you need to get to 600mm.

Nikon AF converters are engineered for Nikkor glass and Sigma converters were engineered with four specific lenses in mind. The 120-300/2.8 is one of them. I wouldn't call it a matched converter exactly but I think you'll find superb performance with it and the price is attractive.

The Kenko Pro 300 series 1.4 TC is quite good with some lenses and not so much with others. I've had mixed results. On my Nikkor 300/2.8 it created rather harsh CA on some images but with my Sigma 400/5.6 it works quite nicely if I concentrate on good technique.

I have the sigma 1.4 for my 100-300 f4 and to be honest you have to pixel peep close up to see a real difference.

D200 sigma 100-300 f4 1.4x @ 420mm f13 1/200

I use both the Sigma 1.4 and 2x on my 120-300 and I am very pleased with the results.

Here are 2 examples at 600mm

Thanks for the support guys, I ordered the Sigma 1.4x teleconverter from Canoga Camera with 2d day UPS air shipping for just $2 more than the base price from B&H.

Should have it here by the weekend!

So, instead of a 120-300mm f2.8 I know have a 168-420 f4 lens!

B&H is follows the Jewish holiday schedule which can be a hindrance to many photographers who need something right away. In either case I have been happy with Penn Camera in DC, as well as Roberts Imaging in IN.
