Rendering comparison with FE 24/1.4 GM and Loxia 21/2.8 Distagon
Out of the camera. Only sharpening setting for both lenses. (identical exposure and histogram level)
The FE 24/1.4 GM is smoother but the plane of focus is not as contrasty as the Voigtlander (micro-contrast).
Different color rendering as well.
At close distance, which rendering do you prefer?
Voigt 21/1.4 (top), 24/1.4 GM (bottom)
Area of focus for image above. (notice the transition zone)
Same close-up scene above at f/2.8 compared to Loxia 21/2.8.
Out of Focus Rendering: Area of focus: Voigtlander 21/1.4 compared to Loxia 21/2.8 (both at f/2.8)
Area of focus: Voigtlander 21/1.4 compared to Loxia 21/2.8 (both at f/2.8). To my eye, the Voigtlander is sharper and more contrasty at close distance. (Yes, I focused the Loxia right. :))
Me too but I also like the Voigtlander contrast and color rendering.
Keep in mind that the Voigtlander imagers will have less blur since it's a wider FL and they were shot at same distance. (~0.4m)
It's a great way to see the FL difference between these lenses. Everything is the same (WB), exposure and sharpening.
There is a distinctive difference in rendering. The Voigtlander has higher contrast and bolder colors. The GM is flatter in comparison but has smoother rendering...
I didn't get much ghosting flare but there is a persistent purple blob that like to show up at certain angles. Changing the angle slightly gets rid of it.
The Voigtlander 21/1.4 Nokton is capable of defined sunstars from f/1.6 and it's very decent at f/2.8 and smaller apertures.
f/2.8: Can't get this sunstar definition with the Loxia 21 @f/2.8
Man, 21 is right there with the 24GM. That said I like the rendering of the 24 better. Combined with having AF 24 stay's in my bag. I'll just admire images from the 21 from afar
The CV 21/1.4 Nokton has good coma performance at least 1-stop from wide open. At about f/2.2 coma became acceptable and it's optimal at f/2.8. It does not match the outstanding coma performance from the FE 24/1.4 GM which has great coma performance from wide open. Compared to the Loxia 21/2.8, it matches its wide open performance at about f/2.2 or f/2.5.
At f/1.4 coma is very evident but gets greatly improved at f/2
Nice improvement from f/2 to f/2.2. Some would consider the f/2.2 performance already acceptable for astro
From f/2.2 to f/2.5, it improves slightly
from f/2.5 to f/2.8 another very slight improvement
At f/2.8, it has better coma correction compared to the Loxia 21/2.8 wide open

Ha, after all these comparisons, I appreciate my GM 24 more. One day I'll find a good reason to add this CV into the bag :P.
It's true. The GM 24 is outstanding for astro. Lower coma and lower vignetting. It's about a stop better than the new Voigtlander but 24mm is not 21mm.
I'm surprised it did better than the Loxia 21/2.8. (also by almost a stop)
