58 SLIIS was here in less than 24 hours!? Quick and easy win over the Helios! I can't wait to really put this to use. The colors this thing puts out are on a level
Voigtländer 58mm is incredible lens!! Going through my photos I always experience a WOW when I see a picture shoot with it! Excellent resolution, rendering! And did you notice how it renders the blue? You need to go and shoot landscapes with it.
I have the other Voigtländer - 40/1,2 on old Sony A7R and I must say I've never seen such gorgeous 3D-effect! Never! And I have a few Zeiss lenses! The combinaion A7R+Voigt. makes from pictures paintings from 19th century. Really. I am serious.
Voigtländer is known for its vibrant colors by the way. It is from Cosina, where also Zeiss was/is produced. But of course, it has some "failures" like field curvature and focus breathing.
Often the failures (not corrected stuff) make the character of the lens.
From my experience field curvature brings more 3D, less glass elements - more colours. But maybe I am wrong. My Nikon 180/2.8 brings just unbelievable colours. Nobody believes that colours come from the camera+lens ;-) and often ask me: did you saturated it?
I have also a collection of vintage lenses. Three of Heios 44 (on one I reversed the front element), Helios 77-4, 40-2, Porst. Takumar and almost all of Meyer Optik Görlitz.
I tested and found out that Zeiss Milvus 135/2 has more resolution than Nikon S 70-200/2.8. Milvus is now my reference lens for sharpness and resolution.
Sigmas have normally very beautiful Bokeh, better than Nikon (F-Mount).
Each lens also has its own dynamic range for exposure. For example, I can recover a lot from lights and shadows from Milvus 135/2 in comparison to Sigma 135/1.8 in post-processing. It must not be like that, right? Dynamic range shall depend on the camera/sensor and not on the lens. But on practice I can recover more from Zeiss and Nikon than from Sigma (middle focal lenght and wide-angle).
