This is an in-depth review of the Nikon 24-120mm f/4G ED VR lens that was released in August of 2010. The constant maximum aperture, mid-range Nikon 24-120mm f/4 VR zoom lens is a major update to the Nikon 24-120mm f/3.5-5.6G VR that was released back in 2003. The older, variable-aperture 24-120mm f/3.5-5.6 had some optical problems that did not make it a popular lens among photographers, so Nikon decided to address those problems by releasing this highly-anticipated Nikon 24-120mm f/4.0 lens. Why highly-anticipated? Because the 24-120mm focal range is very useful for photographers who use full-frame cameras like Nikon D700/D3s/D3x and who find the 24-70mm f/2.8 either too short on the long focal end, or too heavy for everyday use. In addition, having VR on a mid-range lens like the 24-120mm is crucial for low-light photography, even on the wide end.
Did Nikon address all problems the Nikon 24-120mm f/3.5-5.6G had in this new f/4 update? How does it compare to the legendary Nikon 24-70mm and the new 28-300mm lenses? Is it really on par with the 28-300mm when it comes to performance, making it a worse buy than the 28-300mm like some of the reviewers stated? In this review, I will do my best to provide a detailed analysis of the lens’ performance, including sharpness tests and comparisons against other mid-range lenses and answer the above questions.
