No one knows for sure yet, but based on ephotozine's reviews of the 14-45 and the 14-42II I'd say no it is not worth the upgrade. If you look at their imatest results closely you can see the 14-45 is equal to or besting the 14-42II in all but one case - erroneously high center MTF50 numbers from imatest. This is a known problem with imatest, once things get near or above the "excellent" level on ephotozine there is no point in comparing - you are looking at testing artifacts.Cipher wrote:
I got mine with my GF1. Is it worth the upgrade?
Instead pay more attention to the edge performance. There you will see the lenses comparing closely to each other in most cases. The 14-45 doing a bit better at the wide end, the 14-42II doing a bit better at the long end.
Also note that at least in this case they used the same camera body to test both lenses so there is some value in comparing the two tests (a sadly rare occurrence).
Also note such testing is really better at generating numbers and tables we can score keep than actually telling us much about the IQ of the lenses. My standard link to a good article about how flawed these tests usually are:
And finally, it is worth noting if the ephotozine's review is to be believed and the 14-42II is performing close to what the 14-45 is doing then that is really good news. The 14-45 is a really great kit lens and if the 14-42II is keeping up then that means m43 kits containing this lens will have a leg up on the offerings of most of the other MILC offerings (possible exception being the Fuji zoom - but that is far too expensive a lens to be considered a kit zoom even if they do sell it kitted with camera bodies).
