Build Quality

The Fujinon 50mm F2 LTM is a relatively large lens for its maximum aperture of f2 and it is equivalent to some f1.4 vintage lenses in terms of size. There are two production types with later models offered with a focusing lever. The lens had a black paint barrel design along with a chrome ring on top.

Image Quality

The Fujinon 5cm f/2 lens is a stellar performer, it offers high image resolution and great optical performance. There is a tendency to flare wide open at f2 but when steps down to f4 and beyond, the sharpness increases significantly and image rendering is equally pleasant.

It is uncommon for a lens produced in 1950s to flare at f2. However, when narrow down f2.8 the flare suddenly disappears and the resolution is very high. The out of focus area rendering is both natural and eye-pleasing. In addition, the contrast and colour rendition is towards the lower side with signature Fuji colours.

The Fujinon 5cm F2.8 is much smaller and lighter than the bigger brother Fujinon 5cm F2 LTM lens. It is still well constructed yet feels incredibly small in the hands, as it’s relatively compact compared to the Fujinon 5cm F2 lens.

The Fujinon 5cm F2.8 LTM lens is a step down in terms of maximum aperture but still renders very similar to the Fujinon 5cm F2 lens. When shot wide open, it’s out of focus area isn’t as creamy but very pleasing to the eyes. At aperture beyond F4, both lens produces classic image with signature Fuji colours.

It is extremely high quality lens and feels balanced when mounting on Leica M rangefinders. Overall, It offers a compact and solid package.

Image Quality

The Nikkor 50mm f1.4 provides great image quality with full of character. When shot wide open, the image sharpness isn’t clinically sharp like some Leica lenses but it produces a soft glow common only to certain vintage lenses. However, it also lacks contrast and clarify like on most modern lenses.

At its minimum aperture of f1.4, the point of focus is relatively sharp and the out of focus area provides the soft vintage glow. The sharpness increases dramatically when stepping down the aperture with its peak image performance between f5.6 - f8. The lens does suffer the common issues with older lenses such as chromatic aberration and vignetting. The image quality isn’t perfect but it is unique with classic characteristics, which makes it perfect for monochrome renderings.
