From analyzing the 126 lenses on the D7100 the results are impressive; they’re simply the best we’ve seen from an APS-C camera to date. We compared the data between the D7100 and the older D7000 and as one might expect, the resultant increase in sharpness in the high-grade lens models was dramatic.
In the best case, sharpness increased by as much as 50-percent over the Nikon D7000. Some moiré was noticed, however, though it can be reduced quite effectively with a good quality Raw converter.
Models that had performed well in the past such as the AF-S Nikkor 85mm f/1.8G see an impressive gain but other, slightly less capable performers have seen more substantial improvements in acutance.
The sensor of the Nikon D7100 is capable of extracting hitherto unknown levels of detail from a wide variety of lenses.
It’s not just the expensive high–grade lenses that benefit from the high-resolution sensor of the D7100, the results for the more accessibly priced models was also impressively high. We measured improvements in sharpness of over 30-percent with some basic kit zoom models and super-zooms.
A number of zooms see an increase of over 30-percent in overall (averaged) sharpness when used with the Nikon D7100 over its forerunner, the 16Mpix D7000.
While there are a number of models such as the popular AF-S DX 18-55mm f/3.5-5.6G ED II kit zoom that see a significant increase in sharpness (equating to around a 30-percent increase), the more substantial increases are seen with some higher grade models such as the now discontinued AF-S VR 24-120mm f/3.5-5.6G IF-ED – a lens that wasn’t known as being a good performer. Sigma’s 18-250mm models and the 18-200mm f/3.5-6.3 also perform well on the D7100, all three achieving a similar 60-percent gain in sharpness as the previous Nikkor AF-S VR 24-120mm model. It’s impossible to say whether these models may show improvements with an even higher resolution sensor.
