No.
The inset filter dont effect daytime use
and after thinking about it the the filter
closer to the chip for me makes more sense.
Not being a physicist but from working with glass
all the time I'd prefer the light to only get
its 'final filtering' closer to the chip rather than
at the widest light gathering point.

Hey Steve.
I've had a look at the site you linked
and I can seem to see how to buy the filter
off of them!?

Sorry for being a thicko but
how did you order / pay for yours?

In terms of quality, the way I think of it is like a piece of dust.
If there was a piece of dust on the filter on the front lens, it wouild make very little difference to the image.
However, if that same piece of dust were placed very close to the chip, the effect would be immediately noticable as a donut effect on the image.
Therefore, following that logic, the closer the piece of dust is to the chip, and more specifically, the closer it is placed inside focus, the more critical it is for optical quality.
