Fujifilm Fujinon XF 60 mm f/2.4 R Macro
9. Ghosting, flares and transmission
 |
The transmission graph is undoubtedly nice. In a quite wide range of spectrum (from about 450 to almost 700 nm) the amount of light, passing through the optical system reaches over 90%. What’s more, the graph is quite flat and its slope – symbolic. It guarantees very good colour rendition. The maximum transmission reaches the level of 93-94% and is kept there for yellow, orange and red light.

The Fujinon 2.6/60 consists of eight groups of elements. It means the producer had to cover as many as 16 air-to-glass surfaces and the loss of light on one such surface cannot exceed 0.4%. If it had been higher we wouldn’t have got such a nice transmission graph as the one presented above. Once again we deal here with good but not sensational result. The best contemporary coatings have a loss of just about 0.2-0.3% on one surface.
Perhaps that worse-than-perfect coatings efficiency is the reason of such flares as presented in photos below. The Fujinon 2.4/60 doesn’t perform here as it should because the flares (sometimes very intense) appear even when the source of light is a bit outside the frame. Fortunately this lens features a narrow angle of view so in most cases we are able to avoid problems with flares.
