Good point. However, the 600 is almost twice the weight of the RF 100-400, and I guess twice the size since it needs to be extended to be used. And no zoom.

The 600 is about 8 oz more than the 100-400 (32.8 to 24.4 oz) which is almost exactly the weight of the 1.4x extender. So the weight of the combo is the same and the pack size is the same. But the MFD on the combo is 3 feet vs. 15 feet for the 600. And the combo has a macro magnification of .6. And it zooms. The main advantage to the 600 mm is that it costs a lot less than the combo. $1150 vs $700. I am thinking it might be worth it for the versatility, but I am not quite there yet.

Yes, you are correct. I hadn't realized how much the extenders weight.

As always, it's a tradeoff between IQ and size/weight/convenience. Zoom vs prime, etc. Both are nice options to have.

I went for the zoom, but I'm still on the fence on whether to get the 1.4X or the 2X for it (I'll probably go for the 2X, but need more convincing that the IQ is still acceptable for real life shots. In shooting charts, it doesn't look that great).
