Increasing contrast when working in black and white, this 72mm Red 23A Filter from Tiffen is used to noticeably darken cool and blue tones in order to emphasized both shadows and clouds. Offering greater tonal separation than regular yellow and orange contrast filters, the light-red 23A is especially well-suited to producing dramatic outdoor and landscape imagery. There is an approximate 4x filter factor with this filter, requiring an increase of 2 stops for normal exposure.

The filter is constructed using Tiffen's ColorCore technology, which involves lamenting the filter material between two pieces of optical glass, grounding flat to a tolerance of 1/10,000th of an inch, and mounting within an aluminum alloy ring.

Q: 1. Can I control my Canon 5D Mark is through touchscreen. Such as different menus and focusing?

A: I’ve only used mine as a monitor. It’s really great for the price. It doesn’t control the camerathough!

Q: 2. Does it work with bmpcc?

Q: 3. Will it work with computer HDMI?

A: Sure will. You may need to adjust the computer's output resolution.

Q: 4. Can this monitor be used in addition to a HDMI EVF viewfinder?

A: Yes, because this monitor has an HDMI input and an HDMI output. So, you can go into the monitor directly from the camera, then loop out to your EVF. I have done this with no problem on my shoulder rig. That way if I want to come off the shoulder and go hand-held with the rig, I can use the Lilliput for monitoring. Another cool feature is that you can loop through the Lilliput to your EVF and the EVF will get signal even if the monitor is powered off as long as the monitor is connected to an active power source. I've turned the monitor off to conserve battery and still had signal into the EVF. One thing to be careful of though when running multiple HDMI cables to different sources is the HDMI ground issue. If you power both HDMI peripherals from the same battery source, you can possibly damage the HDMI output of your camera. To avoid damaging the HDMI output, you need to have all of the peripherals plugged in and turned on before you turn on the power to the camera. Hope this helps.
