Teleconverter for 70-300 F/4.5-5.6 aaaand polarizers
Any recommendations for purchasing and using a teleconverter on the Nikon 70-300 F/4.5 - 5.6
I am looking at either the 1.4X or 2.0X converter.
Also, any thoughts on circular versus linear polarizers?
For both items above; Nikon only or other brands and where to purchase?

None of the Nikon TC's will even mount on the 70-300mm f/4.5-5.6G ED IF AF-S VR.
The Kenko Pro 300 Series TC's will work in good light.
Given that the 70-300mm is at f/5.6 at 300mm, with a 1.4X TC it will provide f/8 at 420mm. The AF system of the D600 is rated to f/8.
If you mount a 2X TC it will give you 600mm at f/11. The AF will be slow in excellent ambinet light. As the ambinet light level drops AF performance will drop until it stops working. At f/11 the viewfinder will be very dark making manual focusing difficult if not impossible in all but the best light.
I use Nikon Circular Polarizer II's and highly recommend them.
While they cost more than the cheap ones, they are multi-coated which helps reduce flare and ghosting.

Some metering and AF systems require circular polarizers, as linear polarizers confuse their beam-splitting systems. Most Nikon DSLRs are OK with linear polarizers, but apparently not all of them. These days it is just simpler to get a circular polarizer and not worry about whether or not your camera(s) is one of the ones that works with linear or not. Circular ones work for all current cameras.
I have a fairly wide range of CP, and to be honest I seriously doubt anyone can tell results from the Nikon ones from the Rodenstock (high end pro) or Marumi (multicoated, but far less expensive than either). I am likely to get Marumi in the future if I add new filter sizes to the working set. They're probably a third the price of the Rodenstock and half of Nikon and they're quite well made. Others have commented that they are a bit more difficult to clean, and while that may in fact be true it certainly isn't vastly different and overall it doesn't bother me.

As Marty suggests, with good lighting a teleconverter may give you passable results with the 70-300. But I would not recommend it. The 70-300 is a good lens, but if you need a teleconverter it will be at the softest part of the lens - 250-300mm. You'll need to stop down for reasonable sharpness in most circumstances. I find the percentage of keepers to be 10% of what I get with the bare lens - not enough to be reliable. I have a Kenko teleconverter for the 70-300 that has not been used in several years.
I do find extension tubes work well for closeups of insects and flowers. The Kenko extension tubes and 70-300 make a good combination.
