I bought this card for the Canon 90D. A lot of reviews say you need a faster card for faster shooting (sports photography, for example) and certainly for 4K video.
I have tested this card on rapid shot sports photography and it responded excellently and out-performed my expectations. Likewise, I have recorded 4K at 25fps and no lag or dropped frames. Audio perfectly in sync using built-in or input mics. 4K at 50p and higher DID drop frames and have issues. This doesn't bother me, but it might bother you.
I have often found that SanDisk out-performs its own specifications and so I'm glad I didn't spend an extra $200 for the ultra-extreme-pro-superman-marvel-DC-Hulkbuster card. This one does the job perfectly for my needs, which I would say are intermediate level.
