here's a 6x6cm frame with an 80mm f/2.8 and a +2 diopter filter. they do not change the field of view of the lens, they just convert the focusing range from (example) 0.8m - infinity to something like .2m - .5m.
you definitely lose the ability to focus to infinity, or more specifically, on anything past that converted far-focus distance, in this case .5m or so. fun possibilities with portraits. |
How 'bout extension tubes? I use those with all of my lenses and really like the results.
