INON diffusers widen strobe beam angle circular 110°. A diffuser is must item for wide shot or to cover variation of strobe positioning even with standard lens. Another advantage of using a diffuser is to soften strobe light, which helps to deliver natural and even light especially for macro shooting. The -0.5 Diffuser drops strobe power only a half stop, so it is possible to use all time unless full flash amount is necessary.
INON Diffuser 2 comes with two filters. A hollow diffusing filter W40° Filter LE made from two laminated high transmittance optical grade acrylic fly-eye lens to extend Focus Light coverage up to 40° with less light attenuation. Another Red Filter LE changes light color to red not to stimulate light-sensitive subject for observation or macro shooting. The red filter also works to enhance accuracy of S-TTL Auto in super macro imaging by reducing influence of the Focus Light on camera's exposure control.
White diffusers adjust flash output and widen beam angle with minimal
color temperature change. The color temperature of strobe beam through a
white diffuser is 5400K which is only 100K less comparing strobe light
without the white diffuser. INON white diffuser is designed to have same
color temperature of sunlight.
*All INON Strobe designed to have color
temperature of 5500K without a diffuser as same as sunlight to enhance
natural color image.
Color Temperature Conversion Filter (4900K) and -0.5(4900K) Diffuser drop strobe color temperature from 5500K to 4900K. Color Temperature Conversion Filter (4600K) and -0.5(4600K) Diffuser drop strobe color temperature from 5500K to 4600K. Warming strobe light is useful to capture diver's skin more healthy or accentuate warm color subject. Also converting RAW files at 4900K or 4600K can have richer blue water back ground with natural color subject illuminated by a strobe.
INON Z-240/D-2000 strobe is equipped with the External Auto mode where
built-in Light Adjustment Sensor on strobe's front side meters subject
reflectivity to control flash output. This flash mode is a kind of
semi-automatic exposure control since there is no exposure data
communication between a camera and strobe, so user needs to input
camera's aperture value and ISO data in the strobe. Also the strobe has
to be properly aimed to a subject so that the Light Adjustment Sensor
facing to a subject. The External Auto mode is useful for shooting
situation where TTL Auto mode does not work well or for intentional
flash output control. This diffuser has dedicated window for the Light
Adjustment Sensor.
*If you mainly use [S-TTL Auto] and not using [External Auto] mode, then budget priced Diffuser 2 (TTL / Manual) would be recommended.
