Haven't heard a word. I have been watching to see what Pocket wizard says about canon adding wireless, but I haven't seen a thing at all.

A new member "diode" is wondering about this....??? Any new word?

My D4 destroyed five SanDisk CF-Cards the last months. I´ve got ERROR-Messages and there was no way to rescue the pictures files. Because of that I´ve lost a job and the customer. The last CF-Card I took out of the D4 was unbelievable hot.
First the NPS-Service in Germany told me, there´s no problem with the camera. Three months, a changing of the display and a repair of the autofocus system later, Nikon accepts the problem with the CF-card slot of my D4 camera. Now I want to change the camera. The D4 is very expensive. The camera should work in a professional way. But my D4 is the most expensive one, because it´s a instrument for loosing jobs and customers.

Regarding overheated cards in the D4....

I just got back from a trip to Sedona Arizona and ran into this problem with Delkin CF cards.
I had a 32 Gig Delkin card in the CF slot and I shot all day long with it then realized my camera was
acting odd so I turned it off then on and saw the message about "This memory card cannot be used" on the
screen. I then opened the card slot door to smell some burning type smell although not too strong...
I removed the card and it was almost about to melt but it didnt get that far. It was so hot I could not hold
it though.

I am worried that this might have damaged my D4 but I wont know until I get another card for it.
Im amazed that the camera would even let the card get hot like that. I do have other Delkin cards of
the same make but I wont put them in the slot for fear of damaging my camera if it has not already been.

Avoid Delkin cards. I had the same problem with my D300s believe it or not... but not with heat.. more like just
file corruption everywhere.

On page 443 of the D4 User's Manual it lists the "approved" CF cards. They are all Sandisk and Lexar. I have tried others, but have not found any that will work. Err blinks in the information finder and the camera won't focus or shoot. The XQD on the other hand, works great and indicates 1.4K images remaining at Large/Fine/JPEG setting. Very efficient, and maybe the future. Lexar CF cards format and work great also. Fortunately, I still have two D2x's and a D3 to use the CF cards that are "off brand" with. I suspect we will all find similar results.

I noticed cameras with a crapdial (Dx with auto modes have the lath issue as the camera can also determine when to use the flash too) The d7000 and above have a fully manual and more durable latch. (the flash can be opened when the camera is off too). I haven't an issue with mine but you will need to take it in...

XQD cards are so fast I will only use CF for backups now.

XQD is where it's at. I wish the D4 had two of them.

where did you buy the card ?
i gather there are a lot of SanDisk forgeries on e bay

Does the D4 work now with the QXD card in place? And was the CF card inserted with the camera on or off? Was there any problem getting the card in the slot? If off, and no problem getting card into camera slot, it certainly sounds like a warranty issue provided no other condition exists.

I inserted a SanDisk Ultra II CF card into my new D4. It didn't work ! Not only did it not work, but there camera went into some kind of "green light blinking/freeze mode." I turned it off, but light kept blinking. I removed the card and an electrical fire burned smell came from the card and camera !

WTF ???????

I am using those in my D4 without a problem, 32 and 16 GB are working fine. Sorry to hear about your problem, I hope the camera is fine.

So what caused the breakage? I would guess a bump on the flash housing in the direction of opening the flash or with the display cameras being forced open by dimwits would do it...

My D90 has had the same flash latch problem since March. My D800 arrives this week so I can now finally have the D90 repaired (or try to fix it myself).

My experience with Kingston and Transcend cards has been god awful. Transcend do overheat and melt (that was in industrial apps) that caused random data failures on files, and then on the whole card. I doubt a camera would cause that, but then again the heat on the cards has more to do with data transfer (more electricity pumping through it)than anything else. (Assuming you are not in a dessert.)

There are some photographers that say the card don't matter. I find people who say that either A: Have a lack of interest in learning the differences or B: Haven't had a bad experience yet.

So many threads on this but Lexar and Sandisk are the only two that are continuously suggested by most and I concur. Even if one get's corrupted, they both offer free software that you can recover almost everything.

Anecdotal cool story bro, but I have some 32GB Transcend 400x cards that seem to overheat or otherwise stop working right under heavy use (11fps) in the D4. You get a card error, and if you take them out, wait a few seconds and put them back in they are "okay" until it happens again. The card is very warm when you remove it. This is consistent across four cards. I'll be getting some Sandisk or Lexar cards shortly, this is just what I had laying around for now (the D4 was a surprise purchase).

I hope that Nikon does something like the new Canon speedlight and soon. I find all these third party products to be flaky at best. It would be so nice to have something built-in and not added ON.

I found the powering sequence is VERY important when using the mini/flex units. One always have to power the flash first, the triggers second and the last the camera. Powering off should be done in the same order.
One other thing causing trouble is blocking the SB900's filter sensor with any modifiers.

Sorry to take issue with your post Ofeqve, but Pocketwizard specifically suggest starting at the top and working down as you suggest, but powering off in reverse order. Camera-PW-Flash. This is the proceedure I follow and have never had a problem. Maybe you have?

@pictaker, me too. The AC3 is excellent.

So far my new Elinchrom D-Lite IT (400ws) units which have the Skylite radios in each unit are working great. While these of course need plugging in, if we are using off camera flash, indoors, this may not be a problem. My experience suggests the small battery operated units just do not have the power I have needed.....so.. maybe Nikon is not as excited about the new product as one might hope for. Of course, Canon may have changed all that.

I have found the mini can be temperamental using a Flex on the camera is more reliable

have you updated the Firmware you should have version 3.003 (~september 2011)

I do have the flex mini setup, and it seems everyone is happy with them but me. On my einsteins and elinchorms they seem to work great but with the sb900's, they seem very moody. I was actually thinking of getting rid of them. It seems i make an adjustment to my camera then all the sudden ill change a setting, then a flash will stop firing. Nobody else has had problems with them?

I'm another happy camper with the Flex/Mini arrangement and 3 strobes (900/910). I also use the tiny AC-3. Excellent arrangement.

I have the Flex/Mini setup with three strobes, and yes they work fantastically.. but I have to admit it'd be nice to not have to mess with adding "a middle man."

As nether the D800 or the D4, have a flash radio transmitter, it seems unlikely this year or even next

Are you using the Pocket wizard Flex and Mini, once you Get used to them, they are very
good, no more worrying if the flash is in line of sight
