[Leica] Slow CV 20mm for Pentax Nikon

[mark at rabinergroup.com (Mark Rabiner)]

Here to balance out Tom's review of Leica's blazingly fast 21mm is Jonathan
Eastland's review of Cosina new blazingly slow 3.5 20mm.
It's tiny and light & very close focusing with very impressive results as
modest slow glass is prone to give as its not trying to please the marketing
department its just trying to be a nice lens design to take pictures with.

Slow glass gives you more line pairs per Euro;
Is one reason why I love them.
They try harder. They are an little understood underdog.

I'm fond of small outer glass areas.
The savings in lens tissue alone is worth it.
