Nikon D300S vs D7100 - Key Differences

February 22, 2013 | Zoltan Arva-Toth | Digital SLR Cameras | Comment |

In some markets, Nikon is touting the recently announced Nikon D7100 as its new flagship DX camera. Therefore - having compared the D7100’s specifications to those of its most obvious forebear the D7000 - we were curious to find out how it stacked up against Nikon’s last truly pro-oriented DX model, the venerable Nikon D300S (read review). The two cameras share a number of components - such as a 0.94x pentaprism viewfinder with 100% frame coverage, a shutter unit capable of a maximum shutter speed of 1/8000s and rated for 150,000 actuations, a weather sealed construction and an auto focus module with 51 focus points - and a legion of features; but there are some rather significant differences too. The Nikon D7100 comes with a 24-megapixel sensor that does away with the low-pass filter, a new LCD screen, a newly developed OLED display inside the viewfinder, an updated AF system whose centre point can be used with lens-teleconverter combinations as slow as f/8, a so-called “1.3x crop mode,” a 2016-pixel RGB metering sensor, and Full HD video with a number of frame rate options. At the same time the D7100 makes do with a much smaller raw buffer, slower continuous shooting speed and less robustly built body, and lacks the dedicated AF-ON button and PC sync terminal of the D300S. In addition, it uses a different battery and charger and is incompatible with the D300S’s optional MB-10 portrait grip. Upgrading from a Nikon D300S to a D7100 thus involves a number of compromises in addition to the obvious benefits.

In order to help you get a clearer picture of how they compare to each other specifications-wise, we have compiled a handy little table summarising the key differences between the two models, based on information available to us at the time of writing.

Do note that the table highlights the key differences only - there’s a number of interface changes as well, from the omission of the D300S’s physical AF area mode selector and metering mode selector to the inclusion of a D4-style live view mode switch and top-mounted movie record button as well as a completely new customisable “i” button on the rear plate; making the transition somewhat difficult for current D300S users.
