Five Lens rigorous test with Kenko Pro 300 1.4x and 2.0x Telextenders


On this and other forums the question is often raised as to how well the Kenko Pro telextenders work with this, that, or the other lens. Since these telextenders are often purchased for use on other than top-of-the-line lense, I thought it might be useful to show how the combination of lens with these telextenders does, versus the lens alone, and how the combinations with different lenses/types of lenses might work out. Accordingly I designed and shot a pretty rigorous test for this purpose and have posted it in pBase, here:

http://www.pbase.com/hflphotos/nikon_300mm__300_420_600mm

The lenses tested are:

Nikon 300mm f/4 AF
Nikon 70-300mm f/4.5-5.6 VR
Nikon 80-200mm f/2.8 two-ring

Sigma 70-300mm f/4-5.6 APO DG Macro
Sigma 18-200mm f/3.5-6.3

In all there are fifteen combinations: all five lens cover 300mm (approx) and 400mm (approx); three of them also cover 600mm.

Take from these whatever you may learn; I\'d be interested in your comments here.
