I don't think I have seen mention of this one yet. Many have been wondering what would be next in the new Masuyama line and I just noticed this 10mm at 85 degrees. https://agenaastro.c...0mm-mop-10.html
It looks like they are going wide angle instead of the earlier 52 degrees. Hard to believe they can get 85 clean degrees out of 5 elements.
I have many of the older Masuyamas and really like them but I don't have any of the new ones to compare. Would be fun.
