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.
