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.
