"chunk down" meaning the ridiculous extra cost of IS... Here's a prime example...
80-200 F2.8 AF (push-pull version): >300$ used,
*this version is also lightyears better for video on Nikon (or Canon for that matter) because it has an aperture ring, and can change aperture during live-view.
80-200 F2.8 AF-D (faster focusing 2-touch version): 500-900$ used.
70-200 F2.8 AF-S VR II: ~2400$ new, ~2000 used...
80-200 F2.8L ~700-900 used.
70-200 F2.8L IS ii ~2500$ new, ~2100 used.
(also per B&H)
Hell, the F4 IS/VR versions of both lenses run you well over 1000$ and they aren't even close to as good as the cheaper, full stop faster F2.8 lenses that cost well under the price... and in the case of Canon, the cheapest L lens is the ~500$ 70-200 F4 L non-IS, which is under half the price of the IS version... and from what I remember, sharper.
Have a nice day, Bluename.
