This is more of a statement than a question I tried all 3 cards in my SX50HS and all 3 cards worked all 3 cards had a max picture capacity set by the camera at 9999 with the big difference being the amount of recording time... 256GB had 856 hours 56 minutes 128GB had 451 hours 30 minutes 64GB had 219 hours 47 minutes I don't think for me there would be any reason I'd need more than the 64GB card. Of course those will vary somewhat with settings etc.
