There is approximately a 5 stop
difference between the modified CoolPix 990 and the CoolPix 950. The
modified CoolPix 990 can shoot at a fast enough shutter speed to not need a
tripod, even though we recommend using one all the time. |
| Unfortunately we don't have pictures of the
camera being disassembled, but there are pages about it on the net. I'll
provide some links at the bottom of the page for those of you who want to do it yourself. We recommend
letting someone who knows what they're doing take your camera apart. |
| The CoolPix 990 was purchased new on eBay for $400 in June, for the
purpose of having the hot glass replaced with clear optical glass. We hired
Mark
Roberts, who manufacturers the DigiSnap serial port remote control, (for
the CoolPix and other cameras) to do the modification as he's used to taking
CoolPix cameras apart. Mark doesn't have the facilities to cut glass so we
had to cut it ourselves. |
| The glass was purchased from
Edmund Optics
product number

| I've had the hot glass from the CoolPix 990
measured to be 2.8mm thick and this is the closest size replacement.
James Wooten reported his 990 was 2.9mm thick. So I
figured
there was enough leeway for it to work. I've gambled about $60 for the
replacement glass (and $400 for the camera). I also picked up a non working
CoolPix 950 in the hopes that the glass would be the same size but it didn't
fit. |
| The glass was difficult to cut being thicker
than window glass. Chris had to use his wife's jewelers tools to get a clean
cut. |
