I bought a Kenko Pro 300 DGX 1.4 TC from B&H ($127), primarily to use it with my D610 + Nikkor 200-500mm 5.6e long lens.
I was asked by Elliot87 to try it out on my 70-300mm Tamron. I have the SP F/4-5.6 VC USD version that I bought new about a year ago. He mentioned that his wife shoots with a D3200 with the 70-300. I don't have a D3200 but do have a D5100 so tried that one. Could have tried my D90 but didn't.

These two are done without the TC
Shooting from the same spot - both done hand held I shot these with the TC attached.

The files were converted from RAW to JPG with no post processing.
These were shot at the max zoom (300 & 420 with the TC attached) at F 8 & F 10.
You can draw your own conclusions about shooting a stationary item, in good sun. (sorry WB was left on cloudy - the sun came out for the shot and I missed resetting the WB).
I could live with the IQ if I really needed the extra reach.
BUT when I tried some birds and bees (pardon the pun) I was disappointed. These two are the best - and I shot a couple of dozen shots that I thought the focus point was dead on the bird or bee.

Now I'm used to shooting bees with a dedicated macro (105 2.8 and others, with extension tubes, and a magnifying lens - often on my D610) maybe I'm spoiled but I'm not happy with that bee shot. And I'm really spoiled with my 200-500mm when it comes to birds. But I expect better.
I will not be putting the TC on my D5100 with the 70-300mm I would rate that pairing as a "D" grade. Maybe, good light, and stationary object, but na.
I could try this lens on my D610 but doubt I would use it that way.
I do want to see how this TC works on my 70-200 2.8. Will give that a go on both my D610 and D5100. Anyone want it tried out on the D90???
