Upload & Sell: Off
OK guys, sorry to keep you waiting, but I've finally had time to publish the quite wordy review to my website. You can find it here: http://www.ronscheffler.com/techtalk/?page_id=130
For those interested in comparison images from the four lenses, download links are towards the bottom of the page. For those primarily interested in results on the NEX-7, also go to the bottom of the page, though a fair amount about each lens's characteristics is described in the main section. For those not inclined to read thousands of words (I've included a few photos to break the monotony ), there is a brief 'executive summary' at the beginning.
Overall, after only one week of use (so take it with a grain of salt, I suppose) my feeling is the new Voigtlander 21/1.8 is an excellent value and is quite close to the two Leica 21s. When there is a difference in favor of the Leicas, it's generally not by much.
Will I be selling my 21 Lux? I'm not inclined to do so just yet, but the same can be said for the Voigtlander. I'm pleasantly surprised with it and would like to get to know it a bit better before deciding whether or not to sell it.
Let me know if you have any questions or if I missed any points you'd like covered in the review.
To answer the NEX-7 fringing question, here's a screen capture of the NEX with the Voigtlander wide open as well as the GXR with it, also wide open:
FYI: the blank wall image was with the lens set to infinity and wide open.
There is some fringing but not all that terrible and possibly not noticeable in the majority of 'normal' applications... unless you typically shoot snowy or foggy scenes, or with lots of blank, neutral areas.
