    The points in the video were lost on me. He was attempting to compare bokeh of a 1.2 lens to a 2.8 lens. Bokeh is created by several factors such as the separation and distance of the background and distance to the subject. It is a narrow set of circumstances that a prime lens like this is optimum. For instance I love to shoot with the 35 F/1.4 L II, but there is a narrow range that you benefit form the faster prime. Close subjects with a bit of separation and it works miracles. Outside that range the 24-70mm will perform equally well. For portraits for years I have always thought my 180mm f/3.5L Macro was the best lens, a close subject with the creamy bokeh that lens could create I thought was awesome.

    Curiosity of the comparison to the old version has found its hold.
    I was hoping not to do this...but now I feel compelled. I will probably be setting up a test to compare just to see if there is any major variation from my EF versions.
    I bet they are similar and will not see much difference at all.

    First test will be the IS, its dark outside and some indoor shooting should provide a good test tonight.

    Perhaps I shouldn't have linked just that one video. You are absolutely right, it is not an apples to apples comparison. The only point I was going for was that here was an impression that the RF 70-200 f/2.8 was approaching prime quality in terms of sharpness/bokeh, etc, in addition to the size/weight advantage. The RF does have 9 aperture blades vs 8 in the EF. So, in addition to the latest optics/lens coatings, there is reason the RF should be providing better bokeh. Just something else to consider. I'd say the size/weight are the biggest advantages for most people.

    But, I'd be interested in your impressions/comparisons.

    Years ago I carried all primes because they were sharper than the zooms. With these lenses the only advantage of the prime IMO now is that they are faster. They really have become more of a "specialty" lens.

    I did a few comparisons of the RF 24-70mm and the EF 24-70mm L II last night. I would say the IS does matter. The IQ seems to be just a better but not enough that most people would notice and really is not a factor. The specs on the RF 24-70 are misleading, the lens is actually bigger by volume than the EF 24-70. It is fat all the way through, most likely to allow for the IS system. It gives you the feeling that you are carrying a bigger lens.

    I took shots at 1/80 at 70mm to get a comparison. In retrospect I should have probably shot slower to get a real comparison for the IS. The EF was the best of the group shot. But hand held with multiple shots the RF did better. You can see if you can tell which is which:

    Which is which is tough. But I do think the first image (0619) is sharper.

    Also interesting, if the settings were the same, but the first image is also brighter.

    Now...please excuse me, I am suddenly in the mood for hot chocolate and whipped cream.....

    Strange I noticed the brightness to right away. All were taken the exact same spot and lighting just minutes apart. I had it in AV mode with Auto ISO. The camera choose different settings on each lens, one is ISO 1600 and the other is ISO 2000. 0619 is the RF lens. The difference in sharpness is my shaking and unsteady hand and IS.

    For us non Pro's my personal opinion on all the RF lenses is they are not worth the upgrade cost if you live on a tight budget. You are a paying a substantial amount for the upgrade to get a very small fraction of improvement, if any.

    I really like Pye, he is a great photographer and a good teacher. I liked his ring of fire video.
