Originally posted by normhead IN my macro lens poll, the 90 macro and 100 Macro tied for first place in the polling.
MY wife prefers the 90. I don't really have a preference. But the 90 lives in her lens cupboard and the 100 lives in mine so I usually I take the 100. And out in the wild the 100 is WR. We once had to dry out the 90 after an unfortunate incident, that involved a lens change, a rock slope with a lake at the bottom. It's amazing how fast those little suckers can move if they get away from you.
The 90 was one of the top rated lenses on every platform on DxO.
If I remember correctly, I think I picked out the Tamron in your poll...
In tests, I seem to recall the D FA100 WR fares very slightly better in terms of CA, out-of-focus highlight shape when stopped down a little, and wide open performance in general. But there's something I can't quite put my finger on with the rendering of the Tamron that I really like. I don't think I could tell you what it is I see, or why I see it... whatever it is, it's very subtle.
I like the focus limiter on the Tamron, too. It's a pity they left that off the D FA100 WR, having included it on earlier versions. And even though the body is synthetic, I like the way it feels in use.
I also think I might be just a little biased... I bought my Tamron used, in like new condition, with a last-minute bid on an eBay auction, and I paid a pittance for it (even compared to the already-competitive retail price). I love a bargain, which for me equates to something that's both cheap
and good. I couldn't believe the IQ I got for so little money (easily one of my best performance vs cost purchases). My D FA100 WR was also a bargain - I bought it new, but it was very heavily discounted in a sale. Even so, it was around twice what I paid for the Tammy
All things considered, they're both fantastic lenses...
