To respond to both rscheffler's and Yossi's most recent comments.....yes, I too believe the replica lens does retain most of the 8E characteristics with some of the differences anomalies shown by rscheffler, Yossi, myself and others. For myself, those abnormally sharp corners at infinity of objects clearly out of the depth of field sometimes is quite noticeable and is clearly different than the 8E I shot with previously. I didn't seee evindence of thois in Yossi's test image. My copy (and from what I've seen of Yossi's and many others posted test images) displays little focus shift (except for what rscheffler has shown in his copy), so that generally hasn't been an overall issue. I haven't encountered the hot spots in the bokeh balls but then again I haven't shot anything that would have provoked it yet. As for wavy field curvature, that too seems from what I understand the providence of rscheffler's sample unless we are attributing the abnormally sharp "out of the depth" of field corners as an indicator of this. Also depth of field drop off is far more gradual than the 8E, lending OOF areas to appear sharper with more definition. That can be a plus or minus, depending on subject matter and individual preference. On at least the Leica M9, there is very noticeable cyan cast to images, especially on overcast days.
Obviously there seems to be differences in individual copies of the replica and it might come down to whether a individual notices these anomalies. shoots film or digital, the calibration of their camera and most of all..something we haven't discussed in length, but the consistency that each lens during construction and subsequent bench testing, is calibrated and adjusted within a set of fixed tolerances.
It would be unfair of me not to also say there are improvements in the replica compared to the 8E. Contrast is better, resolution seems to be higher as does definition of certain objects...and of course having new glass and mechanics. The replica as stated may not be a 100 percent faithful replica of the original 8E, but even if the lens becomes somewhat more expensive than its initial price point, it an exceptional lens in my opinion, when every aspect of the replica from construction, to performance is taken into account. Tweaks to the replica may eventually bring it even closer to the 8E. Even now, the lens has lots of character, a close representation to the original 8E and notable performance overall,,,and that's aside from the faithful construction to the original 8E.
The maker/manufacture should be proud of what he's achieved so far as well like Kevin and others who have been involved in getting this lens off the ground at such a reasonable cost and into our hands.
