Fujinon 8x42 MF
The MF Fujinon series consists of two roof prism devices with the following parameters: 8x42 and 10x42. BaK-4 glass prisms, used in them, are phase coated and set in the Schmidt-Pechan system. The producer emphasizes that all air-to-glass surfaces are multicoated by antireflection layers. Buyers get a set of caps, a strap and a case in the accessory box. The binoculars come with a 5-year guarantee period.

Results of the review
- slight astigmatism,
- excellent coma correction,
- quite good darkening inside the binoculars’ tubes,
- minimum focus already from 1.3 metres,
- good quality prisms made of BaK-4 glass.
- high chromatic aberration,
- not especially impressing field of view,
- weak transmission,
- truncated exit pupils,
- not very esthetic, smelly casing.
I admit that taking into the account the renown of the brand name, looking at the price and a not very impressing field of view I thought this pair of binoculars would have many good and excellent results in our test. Unfortunately it wasn’t the case. Only coma is corrected in a brilliant way; you can also say some positive things about the astigmatism, darkening inside and a good quality of the prisms. The slip-ups are far more numerous, though, and it is hardly understandable…
The field of view is narrow for this class of equipment so it should have been sharp till the very edge and distortion-free. It is not. The binoculars are relatively long which might suggest a significant focal length of the objectives and easier correction of the chromatic aberration. Unfortunately that aberration is corrected badly. The presence of multilayer coatings should indicate good transmission results; however, the transmission’s graph is untypical and the performance – simply weak, which can be clearly seen below.
To sum up these binoculars’ results would be acceptable perhaps for a roof prism instrument with a price tag below 200 Euro. As currently the Fujinon 8x42 MF costs about 350 Euro we can’t recommend it.
