This is rather remarkable. You can read the review by Erwin Puts if you are interested. If you look at the MTF diagrams for the same lens you will see that there is vitually no fall off right out to the extreme corners of the 24x36 area. In my informal shooting with this lens so far I have seen zero visible vignetting and no detectable softening right out to those corners either.You actually need to shoot it with film to look all the way into those corners! The initial press release for the Super Elmar f/3.8 18 says that it has the same properties. I have the Distagon ZM f/4 18 currently and it is excellent, but I shall certainly be looking at upgrading to the Super Elmar when it becomes available. When the intial ad from a French dealer emerged before the official announcement it only showed the Angle of View figures on an M8. Some people took that as an indication that the lens would not perform over the 24x36 area. Purely specualtion. Now even though Leica does quote the angle of view figures for 24x36 the rumour still seems to persist. It morphed into 'oh well maybe it will work for film but that doesn't prove it will work on a 24x36 sensor' !!! I don't know how the doubters intend to prove this currently!! That's the internet for you. No-one questioned whether the 16-18-21 would perform over the whole 24x36 area when it was released. This new prime seems likely to exhibit less distortion that that one, it will be much cheaper and it is much more compact. I think it is an excellent and much requested move by Leica to make this one available. 2009/2/19 <grduprey@mchsi.com> > > > Since it is designed to cover the film format, I would then assume they are > talking about either format.
