My lens arrived today. I've just taken some crude test photos, but the first disappointment is my assumption of focal length being longer than the Nokton 50mm 1/5 ASPH, based on FOV specs quoted by Cosina. An FOV 47.3º for the Skopar, 46.3º for the Nokton and 47º for the Planar.
The Planar is quite a fair bit wider than the Nokton 50mm ASPH II (now sold) and the Skopar is as wide as the Planar. So the specs are not representative of what one sees in practice.
My copy is also not optimally centred. The left mid-zone shows more astigmatism than the right side. (probably still in "spec") No option for return. Over the years Robert White on more than one occasion told me "It is virtually impossible to get a 'bad copy' as every lens returned for apparent poor performance have all been checked by Cosina and every single lens comes back to us within tolerances" I suspect I'll get the same answer this time too.
How does a 0.7 degree difference affect you in anyway? What kind of photography are you doing that this is an issue?
Maybe you didn't understand what I wrote.
In practice, the Skopar is wider than Nokton, which in turn is wider than the Summicron. Framing is an issue. The Nokton which is supposedly "wider" than the Skopar according to specs, is actually longer in practice.
Now coming from the Summicron, and shooting the Skopar or the Planar, the angle of view is much wider. Its not 0.7º!!!

I got the numbers mixed up in my head. 47º is obviously wider than 46.
