Originally posted by Jyrkira It needs its own topic I think, but some findings and opinions:
- Well build
- Compact
- No distortion at wide end
- No distorion at tele end
- Seems to be sharp.
- The aperture is 4.5 at 70mm
All the things above together with WR made me want to change my 17-70 to 18-135.
here are my impressions to what you stated,
1.> well-build - nice
2.> compact - great, expecially for travel
3.> no distortion at wide end - the main thing that I hated with the kitlens and other zooms at the wide end. glad that Pentax seem to have this fixed. otherwise, some precious time wasted during post-process. distortion can really be a PITA.
4.> no distortion at the tele-end - I think I expect this already.
5.> seems to be sharp - it needs to be sharp, otherwise, fail.
6.> f4.5 at 70mm - the 17-70 is a goner. probably same for the 16-45 and 16-50 even perhaps.
7.> WR - nice additional feature.
