Both have pluses and minuses, they are both full frame, have dual card slots SD and CF, 100 view finder coverage, weather sealed body, both have a somewhat similar Continuous Shoot Speed, both have excellent auto focus systems, and both now have new headphone jacks.

Dave Dugdale reviewed both Canon 5D Mark III and the D800. He shoots with both of these camera for awhile and have been taking them both everywhere .. go trying them in side by side in different lighting conditions, cloudy, mixed lighting, extreme low light, swimming pools, silhouettes, even time lapses, comparing skin tones, slow motion, landscapes, and pictures styles, and he founds some interesting stuff about these cameras that no one else is talking about.

I didn’t believe my buddy when he told me that his brand new Nikon D800 viewfinder was always out of focus. I assumed that he had the diopter out of whack. It wasn’t until I used the camera myself that I realized there was a serious problem. The camera was sent back to Nikon for repair and he received the camera back last week with the same issue. After sending it back a second time, Nikon has admitted that “a run” of D800s have an issue with viewfinder alignment.

Steven’s camera (serial number 3003228) seemed to have 2 separate issues; focusing, and viewfinder alignment. Sometimes autofocus worked properly, other times it was way off. When the camera did focus properly the scene still looked slightly out of focus through the viewfinder. After doing some tests with live view and then comparing his D800 to another, Steven confirmed that there was something very wrong with his copy.

Steven ordered his camera the day that it became available for preorder and was one of the first to receive it in the US. He got his camera weeks before me and I’m an NPS member. He has now spent $250 shipping the camera back to Nikon twice for repair. Nikon claims that the autofocus issue has been fixed but to repair the viewfinder will require parts that will not be available until next month. They are willing to refund his money for the camera so he can buy another (not including the $250 in shipping he has spent) but he knows it could be months before he receives another camera because he will be in the back of the line.

If you have a D800 give your viewfinder a second look. With Steven’s camera you could autofocus, and then lean in toward your subject and the scene would finally drop into focus. Does anyone else have this issue? Luckily my D800 is working fine.

Update: About an hour after this post went live Steven got a call from the head of Nikon Service and Steven will be receiving a new camera directly from Nikon tomorrow. Sadly, they will not be refunding the money he spent to insure and mail the lens back to Nikon twice.

Another interesting note is that one of the commentors below claims to be having this exact same issue with his D4. We will keep you posted as we learn more.

Nikon has announced the D800 and D800E 36MP full-frame DSLRs. The pixel count of the long-awaited replacement for the D700 means it also trumps the D3X as the highest-resolution camera in Nikon’s lineup. As well as the ‘stock’ D800, Nikon has also revealed a more expensive model, the D800E that will be free from the effects of an anti-aliasing filter. Aimed at studio and landscape professionals the D800E should theoretically begin to rival medium format digital equipment in terms of resolution.

Over the last couple of weeks we’ve covered every aspect of the Canon 5D Mark III “light leak” issue. Starting initially as a rumor, Canon eventually confirmed that the camera’s top LCD did, in fact, alter the exposure reading by 1/3 of a stop in dark environments. A week ago the company even put shipments on hold while they investigated the issue more extensively.

That investigation culminated in a press release earlier today. Besides specifying that only 5D’s with a serial number whose sixth digit is “1″ or “2″ are affected by the issue, the press release also claimed that while the LCD does change the display exposure, the image will only be affected in “extremely dark environments,” and even then not “noticeably.” Those customers who are still concerned and want further peace of mind will have the opportunity to send in their cameras for an inspection free of charge starting in mid-May.

On the other side of the dispute, Canon customers might find it hard to believe that the issue is being brushed off so nonchalantly. With so many 5D owners complaining and claiming obvious before-and-after evidence, users may not entirely trust Canon’s judgement on the matter. By admitting there’s a problem and specifying the serial numbers affected, 5D owners may rightfully expect a recall — but it doesn’t seems as if Canon have any intention of going down that road.

Let us know what you think in the comments down below. Is Canon brushing off the issue too quickly? Or is the company doing enough by offering free camera inspections?

Here are few more details about the rumored full frame Nikon D600 DSLR camera. As I already mentioned, any information so far in future cannot be considered as reliable:

• The price of the D600 is rumored to be very low – maybe as low as $1500.
• The sensor inside the D600 will probably be 24MP (made by Sony, modified by Nikon).
• The D600 will probably not have an internal AF motor, which means it will work only with AF-S lenses (just like the D3200 and D5100).
• The D600 will have HD video.
• Announcement before Photokina (September 2012).
• One or more low-priced f/4 lenses will be announced with the D600. For example, Nikon recently filed a patent for a 24-70mm f/3.5-4.5 full frame lens which seems to be designed for a cheaper FX DSLR body.

The above image was published earlier on the Chinese photography forum xitek.com - it could be fake, I don’t know.

For some reason Google has captured several appearances of the phrase “Nikon D600″ on the main nikon.com website:
