SX50 w/ Canon 500D attached...
Thanks for the new no-Lock vs Lock material. It really shows that it has a big difference in output and details quality, not mentioning that without this new feature, several shots wouldn't exist.
Your no-Lock vs Lock video is really good:
Yes, but Rich wrote "To try and simulate what..", so guess that the video just is an attempt to simulate what happens to the LCD/EVF image when pressing the 'lock' button.
You can also check this video from a Chinese review site:
Here you can check the complete review:
The Lock button is reviewed at 0:59, it shows the sever movement of a handheld attempt at full zoom of a very distant subject, then Lock is activated at 1.10. Pay attention to the little focusing frame before and after. Where before reminds me when I tried my Raynox 2.2x TC with my present SX30, and then I even asked Phil to consider an option to increase IS with his CHDK for those purposes
