Hi everyone, looking for 1000x cards on Ebay reveals a few (very few) brands currently offering cards at this speed. There is the more common Lexar (often with the word 'genuine' attached, hinting the fact that there may be lots of fake ones out there?) but there are also toshiba, transcend, hoodman and Delkin just to name a few.
A 128 gb 1000x from a Brand called 'Komputer Bay' cought my eye as it costs 275$ (+- 500$ less then the Lexar counterpart), but the description states: 'NOTE: The Nikon D800 Camera's firmware currently only supports 128GB Compact Flash Cards manufactured by Sandisk or Lexar.'
Not that I really care what the D800 supports, nevertheless it made me wonder if there are this type of limitations for Canon DSLRs too, also I hear that not all the manufacturers actually deliver the promised speed, therefore I thought I start this thread in order for everyone to share their experience with different 1000x CF cards and avoid unpleasant issues when buying stuff like this online, thank you all for posting!
