Excerpt: I warn you, this review is going to be a little biased. Why? Because, as one of those die hard D700 fanatics, I won’t be able to help but compare the new Nikon D610 to the D700. You see, when Nikon introduced the D700, they struck gold. They invented the perfect DSLR , at least to all of use shooters who demand pro quality imagery and performance, but didn’t need or want to carry an oversized, heavy, battery grip body like the D3s or the new supremely awesome D4s.
Conclusion: While smaller, lighter, full-frame mirrorless cameras might be an inevitability, the D610 is as good as enthusiast-grade full-frame shooting gets for the time being. That's not to say that the D610, and DSLRs like it, couldn't take a page from Sony's book. For instance, why not shrink the D610 to the size of the D7100? We've seen rugged, durable crop-sensor DSLRs like Pentax's K-3 come in at a way smaller size than the D610 without sacrificing performance.
Summary: Reviewers speculate that the new shutter also fixes the "oil on the sensor" problem of the original D600, but say Nikon has not even confirmed that such a problem exists. The D610 provides six Picture Controls offering preset combinations of sharpening, contrast, brightness, saturation and hue. You can tweak these controls to your liking, save them and even transfer them to other cameras.
Pros: New shutter mechanism, Full-frame format sensor, Quiet continuous shooting option
Cons: Unique arrangement of external controls, Hard to read LCD screen outdoors
Excerpt: When we reviewed Nikon's D600 DSLR , we said it was a "powerful and very high quality pro-level DSLR with a smaller body and price tag that may appeal to wider range of photographers. It brings professional quality at a more affordable price." Today Nikon announced the D600's successor, the D610. It costs about $100 less than the D600, boasts many of the same specifications as well as a few improvements.
Summary: The Nikon D610 brings full frame capabilities to a larger audience, while retaining most enthusiast-friendly features. Image quality at high ISO sensitivities is very good and a wealth of customization options enables quick access to most shooting controls. The slight improvements and fixes over the D600 make it a strong competitor in this part of the market.
Pros: Outstanding high ISO performance in both JPEG and Raw files, High quality JPEG images at default settings, Wide dynamic range in Raw files, Consistently pleasing metering and white balance results, Solid build quality and weather-sealing, Responsive camera when adjusting settings and handling, Dual SD card slots, Built-in flash can act as Commander for wireless multi-flash setups, Comprehensive camera customization options, DX crop mode in both stills and video modes,...
Cons: Small coverage area of AF array compared to its peers, Slow AF in live view and video modes, Rear LCD prone to glare in bright sunlight, No 'live' aperture control in live view or video mode, No histogram in live view, When shooting in live view, rear screen is blacked out until data is written to the card, Lacks useful customization of 'OK' button in playback (featured in D300S and D800)
Summary: Though competition's increasing for low-end full-frame cameras, the Nikon D610 holds its own; that said, while slightly faster than its predecessor it's not a whole lot different.
Cons: Photos still display some unrecoverable clipping in the highlights that you don't expect in a camera of its caliber, and unlike the overhauled D5300, the D610 requires an extra-cost Wi-Fi dongle for connectivity.
Nikon D610 Review: Second Verse Same as the First, Minus Tons of Dust and Oil
Digital Camera Review
30 December 2013
Excerpt: With the introduction of the D600, Nikon made a full-frame DSLR more accessible than ever before. The D600 was an extremely popular camera, but it had one fatal flaw, a shutter mechanism that became known for shedding particles, dust and oil on the sensor. While Nikon never acknowledged the problem officially, the D610 is clearly an answer to the shutter problem on the D600. The camera is essentially the same in almost every way.
