BTW Canon also use a similar element in their DO series lenses... which are OK (very compact is the selling point) , but not quite as sharp as, say, an aspheric L-series. |
From the comparisons I have seen, the biggest difference seems to be contrast - the DO images have a slightly 'dreamy' quality about them. It will be fascinating to see how this new scope goes - not sure I can handle an 8 inch refractor though...
