    The 1.4x III looks noticeably sharper in the center, but looks noticeably less sharp in the mid-frame and corners. So, overall it seems to be a wash. Based on one quick look, not worth the extra $. The 2x III also does not seem like a big improvement (in fact, contrast seemsnoticeably lower than the 2x II). So much for the idea (not mine, but proposed in other posts) that the 2x III + 70-200 II would magically be a perfect 140-400mm f/5.6 IS zoom lens...

    Your right I took a look again, the 1.4x III is a little sharper in the center. This might be a little improvement in that the long Tele

    Doesn't the way your gear looks improve your photos? The new MkII supertele primes will have, "A highly durable white leather-tone coating ... This is a new, more neutral shade of white compared to earlier lenses. It is intended to indicate that the IS II lenses have evolved..." The white paint on the new MkIII extenders matches the paint on the new supertele primes. Do you really expect people to use an extender with that old, outdated white paint when they can pay $200 more for almost equivalent optical performance, but get a paint that matches their new lens?

    Camera anything is absurdly expensive but I guess that's what kind of makes it an exclusive club. When camera gear prices come down and IQ still goes up everybody thinks they can start shooting professionally. I just have to remember that the best photographs come from the photographer and not their gear.

    Ok, the first lens to review didn't look like much of an improvement.


    But the new charts for the 300mm F2.8 L....even the 2x III is looking alot better, this is making it a lot more attractive

    Interesting to see the difference. I certainly appreciate being able to assess these sort of things in advance. I
