Nikon AF-S Nikkor 58mm f/1.4G review
The AF-S Nikkor 58mm f/1.4G was announced in October 2013, and designed primarily as a premium 'normal' prime for FX format SLRs. By 'premium' we mean, of course, expensive - the most immediately striking feature about the lens is its $1700 / £1600 price tag, which means it costs more than most of the company's SLR bodies. With the very decent $440 / £290 AF-S Nikkor 50mm f/1.4G lens also in the lineup, the 58mm needs to be pretty special to justify this kind of money.
The 58mm focal length may look like an odd choice, but it's deliberately evocative of a legendary Nikon lens - the manual focus Noct-Nikkor 58mm f/1.2 from the late 1970s. Indeed Nikon's marketing material draws a parallel between them, saying the new 58mm's 'design concept' pays homage to the old 'Noct'. Stripped of its marketing-speak, this translates to a lens design which goes to extremes to minimize peripheral aberrations such as coma at large apertures, while also paying specific attention to the rendition of out-of-focus regions of the frame, or 'bokeh'.
To this end, the 58mm employs an optical formula that's more complex than typical 50mm F1.4 primes, with 9 elements in 6 groups including two aspherical elements. The diaphragm is made up of 9 rounded blades to give a circular aperture. The optical unit is located deep in the lens barrel, giving natural shading against peripheral light, and Nikon's Nano Crystal Coat is used to minimize flare and ghosting. Autofocus is driven by a 'Silent Wave' ultrasonic motor which allows manual adjustment at any time.
Intriguingly, Nikon is at some pains to suggest that the lens' imaging qualities can't be fully measured by conventional methods such as MTF measurements. In this review we will, as usual, be looking closely at real-world images alongside lab test measurements, to try to work out what this is supposed to mean. In short, does the 58mm produce pictures which justify that price tag?
- 58mm focal length, F1.4 maximum aperture
- 'Silent Wave' focus motor with full-time manual override
- 0.58m closest focus, offering 0.13x magnification
- Nikon F-mount for DX and FX SLRs (or 1 system mirrorless cameras using FT-1 adapter)
Angle of view
The pictures below illustrate the angle of view on FX and DX SLRs (taken from our usual position). On full frame the 58mm is a somewhat long 'normal' lens; on DX cameras it behaves like a classic 85mm short telephoto 'portrait' prime.
|Full frame (FX)||1.5x DX (87mm equivalent)|
