Design considerations

The main design considerations for LCDeVF

• All standard features such as peaking and zebras (focus and exposure assist)
• HDMI loopthrough > port damage
• On-board batteries > what happened in Malawi?
• External DC input > again
• Universal mountig options > damage and rotation, on side and on top?
• Compatibility with all the "legacy" viewfinders + upcoming Cambo

LCD screen features:

• Horizontal screen resolution at least 800 pixels and over 300 pixels per inch. 
• 24bit color 
• High brightness
• Good viewing angle
• Fast refresh rate

Hardware:

• Pre configured SOC (ST, ADI) or a custom solution?
• What chipsets and solutions are used in Thomson and Panasonic P2 Pro line camcorders for monitoring and signal processing?
• Power supply (features vs power consumption, economy mode)

Mechanical design:

• Cable routing!
• Splash and dust proof?
• IC Cooling? (if needed)
• Drop/shock resistance > aluminum versus modern thermoplastics < fracture when dropped
• To what EVF design most customers are accustomed to? (by release dade)
• Classic EVF look or something new? Sony 801 vs Sony EX3 etc...

Optical module:

• Achromatic doublet or aspheric lens, depends on screen diagonal
• Allow the use of standard 50mm diameter anti fog sheet/foil ($4 per piece)
• ENG viewfinder style diopter adjustment > fast, to avoid eye accommodation to false diopter setting < the most common cause of eyestrain
• interface for interchangeable skirts
• Should not change it's length to avoid reconfiguring the position (for different operators)
