Kowa 883 vs 88a vs 99a

[Socalman]

New to high end scopes, looking at the Kowas. Are there real differences between the older 883 and the newer 88a?

Anyone have experience with both 88a and 99a have strong preference?

Yes. Slight optical improvements/mechanical refinements in the 88A - it’s improved, but no revolutionary changes. The 99A is massive compared o the 88 series.
