Voigtländer 21mm f/4 or 25mm f/4 lenses

I'm looking at super-wide angle lenses to experiment with on the Leica Monochrom camera. As all my lenses so far have a 39mm filter thread, I was thinking about the Voigtländer Color-Skopar 21mm f/4 and the Color-Skopar 25mm f/4 lenses. Are there any clear advantages of one over the other, e.,g., quality issues, flare, excessive vignetting, uneven illumination on the Monochrom etc., and how do folks like them?

I owned both on film Ms in their screw thread versions. Both were very good, but I preferred the 21mm. I never did any comparative tests, but I felt it offered slightly the better image quality. That could just have been sample variation.

 

What I'd suggest is buy the one that fits into your existing lenses focal lengths, or just choose the one whose focal length you prefer. Both are good lenses.

My experience is the same as Steve's, the 21mm I feel has better image quality.

 

Here are 2 images taken with the C/V 21mm & Monochrom.

My 25, bought new, has centering issues and corners are soft even at F8..

 

I think it will be a bin candidate because I would not feel right selling it.

 

Why didn't you return it under warranty if it's faulty?

 

I have the 25/4 and it's a superb lens, one of my favourites in fact.

Thanks for these examples. I like the second image very much, including the nice "sun stars" in the centre.

I used both these lenses on an M4-P and the results were good. On an M9 the 21mm caused edge discolouration and vignetting due apparently to the rear glass being very close to the sensor. I made the images usable with the Cornerfix program but digital noise was noticeable. I never used the 25mm on a digital Leica.

Currently as I no longer have the Voigtlander lenses I use a 17mm f3.5 Tokina and a 20mm f2.8 Nikkor on the M9 with Chinese adapters. Focusing is by guess but it works.

The 17mm Tokina gets used more than the Nikkor (which I shall sell as I prefer the widest angle for church interiors). It needs to be used between f5.6 and f11 for max sharpness. A 17mm Tamron SP performed less well on an M9.

I should prefer to use only Leica ultrawide lenses but not at Leitz prices.

the 21mm Skopar is a fantastic tiny little lens. I am sure the 24mm is too but I have 28mm already so 21mm was the next wide step for me:
