Here are a few with a new lens I bought: TTartisan 50mm f.095. I haven't touch other 50mm after get it. IT is a fun experience for me and it is also a challenge to use which is also part of fun. I like use it on SL2 more than M though. It has great build quality. Out of box, it back focus at MFD, I adjusted it (a great feature especially for such a specialty glass) based on instruction and now it works between MFD to maybe 3M,(I don't care or tested further) which is zone I will use mostly. Hit a perfect focus on 0.95 using rangefinder will be a challenge with this one anyway.
This lens teach me Noct Leica will not be a good fit for me. I was on the fence to get it but now this one will definitely serve the purpose (basically to chasing the shallow DOF rendering none of my other 50mm can offer)
Why I say Leica one is not for me after this experience? For leica one, it will be as big as this one, slightly sharper, also block 1/4 of frame line, also difficult to nail focus,(so sharpness advantage is gone halfway) the same busy bokeh at mid long distance at certain condition (Leica might be worse due to higher contrast I think), very expensive for how often I want use it. (This is the area this TTartisan win big and can survive in my bag )
No, I don't think shallow DOF like this is better. (or worse for that matter.) It is just different which is why I have it. and I don't even prefer its look to 50lux or 50corn APO, but I know they each will give me different looks. I for sure will not bring it with me travel. I briefly test it, f1.1 is already further improve the definition, and if you looks aperture at f1.1, you will realize there is significant difference in aperture size make you realize how special is for a 0.95 lens. At f1.4, it is as sharp as 50lux at center but extreme corner never reach to the technical level I want use for landscape even stop down. (sharp enough but never awesome), there is CA but actually nicely controlled. there might be many technical issue here and there if I put it under test bench, but none of that matters for this one because how I plan to use it.
Anyway, a short write up for anyone consider it. The silver one is gorgeous, as beautiful as OEM one.
Here are some with the Light Lens Lab 35 Cron 8-elelment replica/clone/copy... Finally received mine last week after waiting pretty much exactly one year. But it's not all good news. My copy exhibits very strong combined focus shift and field curvature when stopped down, to the extent that depth of field does not cover the focus shift in the center of the image between f/3.5-f/8. From other user feedback so far, it seems to be a problem specific to my copy, unfortunately.
That said, it seems to work as expected at f/2-2.5, so that's what the following were at, which TBH, is where this lens's character is strongest. Shot on the M240.
