Have not tried these Wavy....there 8 element in 5 groups , so you would think well corrected and has APMs name on them .. a Smyth or Barlow combo inside the EP would do this ..but does this have it?...or is it an entirely new design?AND what type of glass is used?
And does an Apo need a field flattener with these?
May purchase just to try out.
