Best lenses for the 24M-Pix Nikon D7100: Best standard and portrait primes and zoomsBy Kevin Carter - Tuesday October 08 2013 Lens Recommendations
As for the best performing standard prime lenses on the APS-C format Nikon D7100, the full-frame Sigma 35mm f/1.4 DG HSM A continues to lead the way with it achieving the best overall image quality score of those tested, followed by the modestly priced AF-S DX Nikkor 35mm f/1.8 G (and best value of the group).
In third place is another full-frame f/1.4 lens, though like other models from the South Korea based firm it lacks autofocus. At $599, it’s a $1200 cheaper than the equivalent full-frame autofocus f/1.4 model from Nikon. That said, while the high-end Nikkor lens achieves a lower DxOMark score of 25 points overall, it has higher levels of sharpness at wider apertures.
If choosing a slightly faster f/1.4 model based on price, the new upgraded APS-C format Sigma 30mm f/1.4 DC HSM A at $499 is very close in sharpness to its bigger, pricier full-frame sibling.Although it sits in fourth place in our rankings, it’s one of the sharpest models in this range of focal lengths.
Macro lenses are attractive for their versatility and there are nearly always very high performers optically. Nikon offers a wide range of models for both FX and DX format cameras. As the joint second sharpest lens in the group (scoring 15P-Mpix), the AF-S DX Micro Nikkor 40mm f/2.8G is both small and light in weight and it‘s accessibly priced at $280.
