    Cons: Just a little too much purple fringing wide open on high contrast edges (rare) -minor quibble. Needs focus limiter.

    Pros: Great image quality. Terrific build quality. Amazingly compact. Very versatile.

    Summary: Small, high quality tele-macro with Limited level build quality.

    Cons: - The interior barrel and hood mount are plastic, but it’s a welcome trade-off for a lower price. - The interior barrel extends a lot. I’m just not personally fond of lenses that have any type of extending barrel because it won’t ever be as water resistant as ones that don’t. However it’s really unlikely a lens like this would be made that doesn’t have an extending barrel due to the large amount of travel the front lens element makes (fully extended, the lens is almost twice as long). - Chromatic aberrations, specifically purple/green fringing, is visible in extreme lighting conditions.

    Pros: - Full frame lens (the FA specifier in DFA). Even with only APS-C available, it gives those cameras the “sweet spot” effect. - Extremely sharp lens. - Extremely good background blur (bokeh). - Very nice contrast-y color rendering. - Weather resistance. - Solid aluminum casing and focus ring. - Macro ability. - Image quality is still good with a decent teleconverter. - Quality related aspects of a DA* or Limited without a premium price (casing, lens details and serial number on the focus ring, solid feel). - Aperture of f2.8 is nice to have. - Relatively compact size. - Images are nice and bright through the whole frame even at f2.8.
