Ron, you really should have gone with DAG. He know everything about M glass. Even 35mm pre-ASPH with bug eye, one of very difficult lens to fine tune. My 50mm Lux perform better than new from factory after he did a fine tune for me at very reasonable price. I sold my 40mm f1.2 as I feel 50lux is the better lens for me on Leica M platform. I haven't see a better glass than 50lux ASPH at this focal TBH.
Thanks, probably next time. I was in NYC for a few days and the M240's shutter blew. I also had a relatively minor problem with the 28 Lux festering for some time, so decided to make the trip to nearby Leica NJ and drop off all three. The camera and 28 are being covered under warrantee even though they were both outside warrantee coverage, so the cost of the 50 Lux repair is a compromise for some convenience.

for what it's worth, i did not find the mid zone dip to be troublesome on the lux asph using my UT even wide open, where i could focus in the mid zone.
I find it less of a problem wide open or well stopped down. It's in the 2.8-4 range where it gets 'funky' IMO. Also sometimes planar type subjects where I might want good across-frame sharpness show the mid-zone dip if f/2.8-4 is necessary for the ambient light levels while maintaining a reasonable shutter speed and ISO. Otherwise, if I have the option, I will stop down to f/5.6 or more. Like Michael, I typically use the Lux either wide open in the f/1.4-2.0 range (considerable central sharpness/contrast boost af f/2) or stopped down past f/5.6. Sometimes this is to avoid the mentioned ninja star bokeh. Other times to avoid the mid-zone dip.
Being able to EVF focus off-center definitely helps with the dip, unfortunately for me it's not an option with the M240.

From the images I've seen (and I read through the entire 40/1.2 thread) these CV 1.2's render nothing like the Summilux ASPH. Nothing does really. (save for the 0.95 Noctilux at 1.4)
Yes, while the Lux rendering is great, these Voigtlanders are good in their own right. They're not the same, but I don't think they need to be.

I can’t help but reference in my mind the lensrentals test comparing among others the 50 Lux vs the Otus 55 and Sigma 50. The 50 Lux held its own and surpassed the competition in sharpness, i.e. on center frame and mid frame, wide open. It beats the Otus center and midframe at f2 as well. I love It on an MP240, but on an A7r3, the Lux shines at center frame, resolving an amazing amount of detail. The bokeh is very distracting though wide open, and edges smeared a little, but that “ Leica look” still somewhat remains.
It’s perfect on an MP240 though, and it’s the lens that really got me hooked on rangefinders. Maybe the 50/1.2 will give it a run for its money, but I’m sure the 50 Lux will go down swinging. ...Show more →
One thing with Roger's test: he admitted to cherry picking the best mid-zone values for each lens, from either their tangential or sagittal plane, whichever was higher. He did not average those values. Therefore the Lux ASPH MTF numbers look amazing. But he hinted at the differences in the two planes in the 'Astig' column, where you'll note the Lux ASPH has the highest value. If you look at Leica's MTFs, at f/1.4 tangential and sagittal values track fairly closely together. As the lens is stopped down, they separate a fair amount in the mid-zone area. For me at least, it mirrors what I see in use and a reason I tend to use the lens either wide open or well stopped down.
The Lux ASPH is great for what it is, but in the past ~10 or so years, it seems everyone else has really ramped up their lens design and manufacturing capabilities. In this respect IMO, technically, the Lux ASPH, could benefit from a refresh. The question is whether Leica can do this while maintaining its relatively compact size. They seemed to be able to do it with the 50AA, but at a considerable cost.
Link to the Lens Rentals 50mm comparison.
Would be interesting to see where the Voigtlander 50/1.2 lands in comparison. However, IIRC, they keep a small inventory of Voigtlander lenses due to low popularity and service/repair considerations and therefore don't have the numbers to generate reliable MTF values (I have asked before if they would test these lenses since Cosina does not provide MTFs).
