Hi all,
I've been down in the pit lately copying old family S8 reels to D8. I've noticed a hot spot on the center of the screen, it's as though the bulb itself is projecting a faint outline of itself in the middle of the screen. It only shows up in brighter scenes, darker more colorful scenes appear to wash the faint whiter circle image out. Is this normal for an elmo F1.1 lens? Zooming the lens in and out/refocusing doesn't help, the image is always there. Any suggestions or is this the nature of the beast.
Also, I've noticed dirt/dust spots inside the lens, cleaning both exposed ends of the lens doesn't help, must be inside between the lenses. How hard is it to tear down an F1.1 lens clean and reassemble?
And finally would an upgrade to an F1.0 improve things at all, if so, what specifically?
Regards, John
