Fast Cap |
Protect
your lens with a lens cap that you cannot loose. Use the
Fast Cap.
It screws onto the front of your lens so it never comes off. Flips out
of the way when your using the camera, snaps closed to protect you lens and
filter. Filter must be installed first, and it is likely to vignette at focal
lengths less than 45mm.The Filter Cap is the same idea, except it is held
in place you your protective filter. The filter cap is not as deep,
and is is not on top of your filter so it is less likely to vignette as much
at wide focal lengths. |

Polarizer Filters |
| There are two common types of polarizer
filters. The Linear and the Circular. The end results will look
the same, but how the light is polarized is the difference. Great
variances in metering and exposure or the inability to focus in some
situations can be traced to using a linear Polarizer on an auto focus
camera. The Circular Polarizer must be used with any auto focus
camera, or any camera using a beam splitter for metering or focusing.
Some older cameras like the Canon FTb use the Circular Polarizer because of
the beam splitter in the meter. All new Canon, Pentax and Nikon auto
focus cameras us the Circular Polarizer because of the beam splitter for
focusing. All other cameras can use the Linear polarizer. If in
doubt check your instruction manual to be sure. |

Degrees Kelvin is a description of the color of light. Daylight
film is 5000K. Actual day light will vary around that Kelvin temperature
depending upon time of day, cloud cover and other conditions. Tungsten
light (because the filament is made of Tungsten metal) can vary from around
2800K for household lights, to 3400K so called amateur Tungsten, to 3200K
Tungsten light. There are no standard filters that will correct for 2800K
lamps to daylight film. You can use a 80B
blue filter to correct 3400K lamps to daylight film. An
80A will correct 3200K lamps to daylight film.
What if you have tungsten film you want to correct to daylight? Use an 85
series filter to correct 3200K Tungsten film to daylight.
