Originally posted by pepperberry farm I am interested in the 105mm macro; I have the 70mm macro and it's sharp but was curious also about the differences between the 105 EX and the 105 EX DG...
why do you only shoot the 105 wide open?
Yes, the user reviews are not easy to tease out the differences between the EX and the EX DG, are they? My 50mm EX DG is really good, and the reviews are consistently very positive. I have seen a couple of the 105s available but never been sufficiently convinced, comparing to the universally positive (even if slightly lower scoring) of the various Tamron 90s, and the Pentax 100 Macros. As well as my Sigma 50mm I have two Tamron 90 MFs, both 1:2 macro, so I would probably only go for a 100mm macro if an AF Pentax.
