the G series.

http://nikonrumors.com/
http://www.sony.net/Products/memorycard/en_us/xqd/index.html

per this site backward compatibility is there. just probably not the speed though.

http://www.photographyblog.com/news/cfa_develops_xqd_2.0_specification/

trying to contact sony for an answer is frustrating to say the least. called through their tele tree after 3 minutes minutes of listening to junk got to a live voice that tranferred me to another live voice that then ended up with the individual at the other end muffled and unreadable after a total of 20 minutes in the Philippines.


nikon also had no idea idea either. but at least i could here and understand them.

maybe someone will have an answer at Photo Plus.

Would be great if we knew how fast they are [really] in use in a D4/D4s

i believe they will be limited to PCIe 1.1 capabilities as are the current cards. but this will only be determined once true backwards compatibility is factually established by both companies.

PCIe 1.1
Base clock speed- 2.5GHz
Data rate- 250MB/sec
total bandwidth- 8GHz/sec
data transfer rate- 2.5GT/s*

Nikon USA site says that they are compatible with current camera bodies.

thank you very much. here are the links:

this link is referring to the D4s only. last Updated 10/27/2014 10:23 AM

https://support.nikonusa.com/app/answers/detail/a_id/19058

at this time the link to the D4 has still not changed. last Updated 04/18/2013 11:38 AM

https://support.nikonusa.com/app/answers/detail/a_id/17780

so, yes, the new cards are supported by the D4s and now we need to see if there is any real difference other then proposed speed increases of the card and the price reductions. is there something under the hood?

ordered (2) 32GB G cards

I only had 4 xqd cards so I ordered two of the 32gb for myself.

It will be interesting to see what the real speed advantage is.

yes it will be if any.

if we moved to PCIe 2.0, or possibly 3.0. then there might be a "little" difference.

new G series card:
transfer rates card to computer:
via Lexar Workflow XR1 reader thru USB3- 169MB/s average
via supplied Sony USB3 reader: 222MB/s average

Due to this card there is a slight buffering increase so it adds ~15 or so shots to use before there is a hit on performance. buffer clears faster too.
