comment Does high reflectiveness of digital sensor lead to poor lens performance?
Thank you. Without compare with film taking with same condition, its still not conclude to which extend the higher reflection rate of IR filter make internal reflection worse. Its better to understand this effect, either make utilize or avoid it.

comment Does high reflectiveness of digital sensor lead to poor lens performance?
thank you. I see your newly edited photo after 14 hours. Did you use a filter? According to the link you provided, the ghost image is due to light bouncing between film and filter. Its the filter, not the back lens element bouncing back the light. So, no conclusion can draw that lens in film era has poorer performance in digital era.

Nikon has a Low-Reflectance Si Light Shielding Film Technology, [link]nikon.com/about/technology/rd/core/optics/arlssc_e/index.htm , but only apply to microscope, not for visual art application. The existing old days technology may sufficient in visual art applictaion.

comment Does high reflectiveness of digital sensor lead to poor lens performance?
Yes, digital sensors is more reflective. The article in the link said that film reflectance is a source of glare already. Lens maker must cope with this issue. Its hard to fine tune the production just sufficient for film reflectance. Without actual research or testing, the only conclusion can be drawn is under extreme critical situation, digital sensor has poorer glare performance. I accept this answer for it enlightened me.

Without actual research and comparison of impact of different reflectance between on film and digital sensor, no conclusion can draw digital sensor is inference in this sense.

Besides back lens element is a source of internal reflection, is digital sensor also a source of internal reflection?
