Originally posted by mtngal Right after I got the Viv I had the chance to compare it to the non-WR Pentax and found it hard to tell them apart (though I was only shooting in a store, not parts of flowers).
The WR version is essentially the same, maybe slightly better (newer coatings, better manufacturing tolerances, rounded aperture blades) so if you liked the non-WR, you can only be happy with the WR.
Originally posted by mtngal I also like the idea of the rounded aperture blades, the Viv can have fairly harsh bokeh sometimes
The WR gives a bokeh just as smooth and unobtrusive as the FA50 macro, and that's saying something.
Originally posted by JeffJS I find however, that AF at close macro range, like 1:1, is painful with this lens. This is something I was warned about before purchasing the lens. It Works, once you get use to it but I wouldn't buy the lens JUST to get AF.
In my short time with the DFA WR, I found that using quick-shift then letting the camera fine-tune works very well. The problem is that the DOF is razor-thin at f2,8 (the aperture the camera uses to focus) so ANY movement will influence the AF point.
Originally posted by DanielT74 I suspect that the new Pentax macro will have better coatings and less CA.
Than the Vivitar, probably. But one of the only flaws I've noticed so far with the DFA WR is that it does exhibit some CA. Not much, and only in high contrast situations, but it's there if you look for it. I've never noticed it with the FA50 macro.
