Agree. My only concern with a fast MF 75 is focusing effort. I have the 50/1, which focuses wide open like a 85/1.4, etc and I don't know if I can take any more focussing fun. The DoF of the 50 APO at f/2 is pretty much the boundary of MF fun for me. (I love the 50/1, but 1.0-2.0 is real work for that extra yard.)
I'd be happy with MF on anything shorter than 50, though, particularly a 21mm (please).

It's hopefully unlikely that high end manual focus lenses face direct competition from AF makers like Sigma and Nikon, for many users. Especially true as more of you are seeing the benefits of better focus aids implemented by Nikon.
After spending time using a finely constructed, all metal, made to last MF lens, that makes it much harder to see the mass market plastic cereal pack optics in quite the same way. Craftsmanship and traditional care for the product tends to do that to you.
And there is an honesty about MF lenses, which are generally purpose built to avoid requiring software 'correction' - they are made to last a long time and work on multiple platforms, present and future. The Sigma 90/2.8, not even 100g lighter than the VM 75/1.5 plus adapter, requires minus 11 distortion correction, making it a 'computer lens'. And the hood weighs .. 54 grams! (per Juha)
BTW, the talk of sensor thickness and Leica expertise is merely a background abstract matter, when you see the VM75 was tested by Fred on a Sony camera. It showed minimal CA, no further induced curvature and near 65/2 APO performance.
In some ways it reminds me of the Loxia 85mm, where high end glass does the heavy work inside a tight design - both are seven element designs with high percentages of APD glass, in place of the usual fare of ever greater complexity with its issues of longevity, sample variation, fabrication difficulty, optical correction spread.
Nikon's plastic barrel 85/1.8 - surely one of the ugliest lenses of recent times - is a 12/8 design. The distortion-happy Sigma 90/2.8 is an 11/10, despite being two stops down. That is what you get with mass market lens producers - they simply throw more glass at the design.
Since it is new to many, some choice comments from Fred's review, again the VM on a Sony camera:
'When reviewing the lens, I knew the Voigtlander 75/1.5 was optimized for portrait distance - but I was surprised by the great performance at long distance as well. Not only is it capable of unique rendering but it's also a solid choice for landscapes as well.'
'The CV 75/1.5 is outstanding starting at f/2.8 for the center area, while the mid-zone and extreme corners need a couple more stops to achieve optimal resolution and contrast.'
'The CV 75/1.5 is capable of defined sunstars from f/2 and they look very defined at f/2.8 and f/4 apertures.'
'In real world images, longitudinal CA (LoCA) is not very noticeable even in high contrast areas. There is definitely some green/magenta fringing but nothing out of the ordinary and correction is actually above average for a fast lens. No automatic profile applied in Lightroom so, there is no in-camera nor post-processing correction for this lens.'
'The CV 75/1.5 Nokton is well corrected for distortion only showing a slight pincushion.'
'Due to its outstanding resolution, contrast and lack of color aberration at infinity distance the Voigtlander 65/2 APO E-mount is my current go to mid telephoto lens for landscapes. However, this new CV 75/1.5 put up a great fight when I compared the two. They performed similar at smaller apertures - by f/2.8 it matches the CV 65/2 APO's center, by f/4 it matches its mid-field and at f/8 it comes close to the CV 65/2's corners.'
