I recently received my Nikon D800 and just for to pomp and circumstance I was quick to check it for the left focus issue, which was fine. Considering I bought a reconditioned unit I'd hoped it would be. The one issue I ran into that surprised me was the focus trap issue where when the cameras a1 and a2 settings were set to focus priority and the a4 setting was set to AF-On Only, fully pressing the shutter release button allowed the shutter to release without the camera being in focus and or indicating focus via the "Meat Ball" in the lower left of the view finder. I searched the web and this site, found the AF Rant ( http://www.photo.net/nikon-camera-forum/00bE7v ) And Thom Hogans note about the change ( Next up we have a doozy: you can take out of focus pictures when you've got the camera set to take only in-focus pictures! A setting of "Focus" doesn't actually mean what it used to. In fact, not only does it not mean what it used to, but it also removes a very useful capability that virtually all higher end Nikon models have had for 30 years: trap focus via the AF-On button. This change is so egregious that I made my complaint directly to Nikon: at least give us the option to restore the old functionality via a Custom Setting.) And a few other notes including a video on Youtube. Well, I contacted Nikon and after a bit of wrangling received this message.... ( Response Terrell S. via Email 01/28/2013 04:28 PM Dear Mr. Murphy Thank you for contacting Nikon. Sorry for the long delay in answering. Due to a server problem we had a large number of email responses that were not routed properly. We have solved the problem and are working to reduce the backlog. We hope to be back to normal 24 hour turn around soon. I have asked a technician to take a look at this incident and you will get a response with 48 hours. Sincerely, Terrell Nikon Customer Service ) For those of you that are stout of heart here is the last communication I sent Nikon: ( Hey Terrell, I have to say one thing, you're PDQ (Pretty Damn Quick). Okay, I see what you are saying about the a4 setting. Yes, if it is set to Shutter/AF-ON, the camera does focus using the selected focus mode ( Single / Continuous ) on the select focus point (s). Your statement here: "When custom setting A-4 is set to AF_ON Only,the shutter will release though your priority selection is set to focus and the camera is not in focus." goes totally contrary the what the user manual states and on camera help states. It is also totally different than the way the D700 and D7000 work when set: a1 Focus, a2 Focus and a4 AF Only are selected. Again which state, " Photos can only be taken when the in focus (O) indicator is displayed. So, this is where I see the problem lay. First, this is a change or as many are discussing it, a Bug. I'm not the only one talking about this, I'm just a little late to the discussion because I've only just received my D800. Examples: http://www.photo.net/nikon-camera-forum/00bE7v This is an segment of Thom Hogans review of the D800 where he expressly points this out as a change: "Next up we have a doozy: you can take out of focus pictures when you've got the camera set to take only in-focus pictures! A setting of "Focus" doesn't actually mean what it used to. In fact, not only does it not mean what it used to, but it also removes a very useful capability that virtually all higher end Nikon models have had for 30 years: trap focus via the AF-On button. This change is so egregious that I made my complaint directly to Nikon: at least give us the option to restore the old functionality via a Custom Setting." (Thom Hogan) Full link to Review here: http://www.bythom.com/nikond800review.htm And another Thread: http://www.photo.net/nikon-camera-forum/00aZ5a And there's even a very good youtube video that demonstrates the issue as compared to a D300. http://youtu.be/lRDEu038S4c The D300s manual has the information about Release and focus on pages 263 and 264. The one thing in every one of these conversations and reviews has missed is that Nikon has not changes the wording in the Users Manual or the Help Menu on the camera but the function has changed. Again, I can go back to my D200 (I still own) which also has that setting and works as I describe it and the youtube video describe it. Page 148 in the D200 Users manual. For some this may not be a big deal. Me, I've used this setting all the time as do many of my photographer friends. All the way back to my D200. This ability to limit random out of focus shots seems fundamental to me and many others. AS an example I lay the D800 on the passenger seat next to me when I was out shooting with it. The camera rolled over onto the Shutter Release Button. The Camera was set in Continuous Low Release Mode. With the lens facing the seat back it proceeded to take a series of non focused shots. I'm also having a hard time believing that someone at Nikon hasn't brought this up. So, I guess what I'm saying Terrell is I hope you understand the issue now and see that there is an issue here. While the literature and help manuals remain the same, something has changed and not in a good way. From the first message I stated I hope there is an update coming for this issue or Nikon will correct the way the manual and help messages are worded. I'd prefer correcting the issue. What I am looking for here is a bit of information as to whether this will be addressed. Because I need to make a decision whether to return this camera or keep it, hoping Nikon will correct this issue down the road. I would welcome the opportunity to discuss this with someone in the tech department.
