I've replaced one original Delta 116 with an HD 215 lens of my 2 years old Zenith KPPRO880X, to improve the sharpness of the blue channel. The result is very good and now the sharpness of the blue channel is about the one of the red channel, which is still using a Delta 116.


I was told, that I have to replace the C-element too, because it wouldn't be possible to use the C-element of the Delta 116 with a HD 215. Until now I haven't changed the C-element, because that seems to be not so easy.


What would the HD 215 C-element improve? Would it make sense be replace it? Do the Zenith projectors really use different C-elements for these both types of lenses?


Thank you very much for your assistance in advance.
