Delkin Devices 128GB CFexpress Type B Reviews

Captures subtle light

By Jeri
Rated 5 out of 5

I purchased my first Delkin card (512 GB) when it was on sale last year and recently used it. I was amazed by the subtleties of light that it captured when taking pictures with my Canon R5–there was minimal post work. Since the price of SD cards continues to climb, I decided to purchase the 128GB in the hopes that I will always have an Delkin card available. I agree with a previous reviewer—Delkin cards make the R5 shine as a creative instrument.

Great quality fair price.
