Voigtlander APO-Lanthar 50 vs Summilux 50 1.4ASPH

I currently own a leica m10 with summilux 50 1.4 asph. I love the picture out of the summilux except the summilux's bokeh balls when stepping down the aperture. I can live with a "stop sign" bokeh, but the summilux sometime gives a "ninja star" bokeh. 

After going through all the comparisons between 50 apo summicron & summilux, I can see the difference between the two and I prefer the 3D pop from the apo summicron. If summicron apo scores a 100, I would say summilux scores a 86-90 (grade A+ on apo summicron vs grade A on summilux). 

I can't justify spending 9k on a apo summicron for that slight difference, especially the summilux is also an APO design. That money can be spent on a good trip or several workshops. However, the Voigtlander apo-lanthar 50 is only 1k, so my GAS mind is thinking whether it is worth getting it? (Unfortunately I'm in a small town where renting a lens is not an option). 

 

Although the apo is really design to eliminate the purple fringing, I'm more focused on whether the voigtlander can deliver that "3D pop"? 

I've Google on the internet & youtube videos, it seems nobody has ever compared these two lenses on a M-body camera.

I believe you will find your answers here : FM Test: Leica 50/1.4 Lux vs Voigtlander 50/1.2 Nokton vs 50/2 APO

Yes, it has a dimensional feeling, but like most f/2 lenses, it's strongest shooting close to MFD wide open. The CV 50 APO has quite a bit of vignetting wide open at infinity, but less at close distance. One unique thing about the CV 50 APO is circular bokeh at f/2, f/2.8, f/5.6, and f/16.

On Fred Miranda, I recommend the CV 50 APO thread that has a lot of contributor image samples.

Have you considered the 50mm f/1.5 Nokton ii? We have an image and discussion thread running in this forum if you want to poke around in there!
