Maybe I should start thinking about letting go of my Tamron 90mm... WR "pseudo-limited" very nice... :think:
But fengwei, I know you said you took everything with AF, did the AF hunt more than usual? Macro lens AF tend to have a habit of hunting due to the super long focusing throw. More of a concern since there's no focus limiter.
As much as being a very good performer, I find the physical design of the Tamron 90 not to my taste. Somehow I had grew to place equal importance in how a lens look and how well it performs. The DFA100WR is really quite a winner in this aspect. But it havn't ticked my LBA. I am actually more interested in that ~$6k FA*200mmf4.0MACRO on ebay. Just kidding... d:Maybe I should start thinking about letting go of my Tamron 90mm... WR "pseudo-limited" very nice... :think:

Gengh, you can always throw in you tamron 90mm Macro to me. my hands all the way nicely wide and open... :bsmilie:
Since it's a macro lens, the focusing is optimized for close distance. At distance of 1 to 3m (portrait distance), the focusing throw is very short, so the AF speed is pretty fast in this range. But of course if you mis-focus, it's gonna take a while to let the lens come back from hunting If you point to the right target before you press the shuttle release button, it'd be fine.
US$850... *cough cough*... I think still need to wait a while before I can consider getting the 100mm WR.
That's already much better than the Tamron 90mm. The Tamron seem to have a habit of "searching" in the wrong direction (even if you start pretty close to the correct focusing point) and end up winding to and fro one big round, both for macro and normal distances. So I usually just use it MF.
lucky i LBA immune :bsmilie:

for you it's not immune but it's no point since you won't be using or needing it most of the time.
