One of the readers of my blog has pointed out that I haven’t wrote about using XF 80mm f/2.8 Macro for infrared photography. Well, in infrared I take landscapes and for landscapes I prefer wide angle lenses. But inspired by the inquiry, I decided to give this lens a try.
My standard test scene, used in the first row, is the wall of green plants in the backyard. I have taken a series of shots at various apertures.
At the first sight, at f/2.8 it looks not so bad. But at closer examination, an ugly, pink and fuzzy range in the center becomes quite visible.
While closing up the aperture, the discoloration becomes more prominent and less fuzzy.
Finally, at f/22 there is a well defined, very obvious and visible hot spot at the center.
Unfortunately it is very clearly visible, that the XF 80mm f/2.8 Macro doesn’t work for color infrared photography at all. Being really careful, I could use it for black&white infrared photography, a shown by the first picture of this article, One needs to be very careful with aperture setting as it is limited to 2.8 almost exclusively, maybe with possibility to go for f/4 in some special cases.
