By Andrew Liszewski A lot of high-end DSLRs still use compact flash cards instead of the ever-more-popular SD and its smaller cohorts. (The Nikon D3 comes to mind.) But that doesn’t necessarily mean you have to buy a CF card which are getting harder and harder to find these days. These handy adapters from PhotoFast allow to use standard SD and microSD cards in your camera via a CF type II compliant adapter. And I particularly like the model in the lower right-corner which actually comes with a built-in RAID controller allowing you

to use up to 4 microSD cards at the same time, theoretically giving you about 64GB of storage with 4 x 16GB microSDHC cards. All 3 of these adapters appear to be available from the PhotoFast website and range in price from about $25 for the SD to CF adapter to about $30 for the microSDHC to CF adapter. Though the microSDHC model with the RAID controller won’t be available until mid-July. [ PhotoFast CF Adapters ] VIA [ Akihabara News ]
