Originally posted by Dewman .... I'll kick it around again! I have both versions of the 18-55mm kit lens, the DA-L and the DA-L WR. In spite of what is indicated in the data on the review page, I swear, there is a difference in the IQ of the two lenses! On mine, the WR lens is far superior in just about every aspect. Sharpness, especially! According to the data, they are supposedly identical in construction, other than the WR feature. Have any of you noticed the difference, also?
I have a friend who also has the same two lenses and he too agrees that the WR lens is the superior of the two. Odd, that. And, I agree with what you said, Paul.... about the 50-200mm not getting much respect, but that's a shame, because it is a fine lens! A FINE lens, indeed!

I think this image shows just how sharp this lens really is! Personally, I don't think the regular DA-L (non-WR) could have produced this kind of sharpness. Nice job.
As I understand it, the breakdown is like this.
DA and DA L are both the same optical quality, no weather sealing. DA has quick shift manual focus, DA L does not. DA L also lacks focus numbering and has a plastic mount.
Now, DA L WR is the same optically as the DA II. All other differences between DA L WR and DA II are as above except that the DA II is not weather sealed.
DA L WR and DA WR both are the same optically, both are weather sealed. Again, the differences are exactly the same as first mentioned (except for weather sealing) as the DA and DA L.
The DA (L) WR came out AFTER the DA so improvements were made in contrast and sharpness. Then those changes were added to the DA and it was renamed the DA II.
So yes, there is a difference between the Non WR DA's and WR DA L versions. No optical difference between DA L WR, DA WR and DA II lenses.
Hope that clears up some of the confusion.
