Very nice image Jacques, really nicely rendered!
The 58 1.4 AFS is really a master at 'painting' the scene vey life like, similar to the 35mm 1.4 AFS btw, also both seems to cope very well with stopping down- I need to try this more with the 58mm so far I have ventured into f/5.6 and all went well.
Food for thought;
Not sharp
Not APO
Not flat field
Not distortion free
But the images can be so crisp and nicely pleasing...
