The new EF 1.4x II extender replaces the previous highly regarded EF 1.4x extender. When combined with the EOS-1V & the EF supertelephoto lenses with image stabilization, near imperviousness to weather extremes is acheived thanks to the new rubber gasket seals. Improved antireflective internal coatings also increase transmissivity & performance in backlit conditions.
Purchased with to go with 70-200 f2.8 (on my 10D) to shoot wildlife. Gives me excellent 'reach' in a relatively light, compact package and minimal loss of quality from an excellent lens. A monopod, at a minimum, is required for sharp images in most situations due to weight and magnification
Strength
very minimal loss of image quality, light & compact
Weakness
not inexpensive

This converter worked extremely well with my 200 mm 2.8 and 70-200 2.8. Pictures were very sharp and I am extremely pleased with the converter.

Summary
Optical quality is up to par with its previous counterpart. AF speed is undiminished-much better than the previous version.
Strength
AF speed of attached L lenses is essentially unaffected. Razor sharp photos.
Weakness
none

Summary
I got this as part of a Canon promotion when I purchased an EOS 3. I could not have afforded it otherwise. The price is acceptable if you are using it with the very expensive L-series telephoto lenses but very over-priced if using it with the 'inexpensive' 70-200 f4L.
Using it with the 70-200 f4L I have had some very impressive results, although the resulting 280mm f5.6 lens isn't exactly fast which has limited the opportunities for its use.
The image is clear and crisp with 200ASA slide film, no apparent vignetting at the edges and just as sharp as using the lens without the extender.
The build quality is equally impressive although the improved weather resistance is only of any real use if you have an EOS 1V and the new telephoto lenses.
Top marks!
