## Questions & Answers

**Q: does this card have the additional 6 contacts on the back?**
A: Yes it does.

**Q: How do the read/write speeds of this sandisk extreme "pro" compare to those of the sandisk extreme "plus"?**
A: Depends on use but if looking to keep up with the fast processors in the latest cameras then 70mb/s for the plus is no contest compared to the 260mb/s on the extreme pro. Have been using the extreme pro in an Olympus Om-1 and have never noticed any issues with buffering and is also very fast to download. Expensive but you pay for what you get.

**Q: Is this compatible with Sony a6000?**
A: Page 19 of the user manual for the a6000 says "Yes -  this will work for photo and video."

**Q: Is it compatible with canon 5d mark iii?**
A: Should be with all Canon models.
