How fast is the HDMI signal switching?

Quite a few people have asked us on how long is the blankout when HDMI signal changes when toggling between rec and preview...



Framebuffer disabled with color bars enabled to show the actual HDMI switching delay when used with a Canon 5D MKII and T2i/550D. If the framebuffer is enabled it looks quite seamless but it's kind of fooling the operator for some 5-15 frames. Anyhow when compared to any other device this is quite fast as the blankout on the only other HDMI viewfinder we can compare to is about 90 frames. And the other one claims just under 60 frames (two seconds).

Our solution works faster on Nikon DSLRs as Canon has some funky-i-frames (you can see 5 of these in the video) before the signal itself stabilizes. So it's camera specfic and Canon DSLRs with 480P rec output are the worst. The cameras with normal HDMI output exhibit no lag at all.

The EVF overall startup time however is under 1000 milliseconds so we can't implement any cool startup animations, loading bars, logos etc ;)...

For the LCD screen brightness reference: This was filmed with ISO dialed way down not to overexposure the screen when compared to daylight.

EVF IQ survey!

>> Take 30 seconds to participate in the finalization of the LCDeVF design. <<

The more sesponses we have the more you can count it will be implemented just before the launch at NAB 2011.

Be sure to check back here to see the outcomes of this little survey.

Thanks!

Tilt Drag Trim...

... via grub screws.

Execution A: ball for applications requiring a single point contact.
Add two at 90deg angle and et voila!

Under further consideration.

The lens samples for the new optical system arrived at last!

I'm happy to report that we have the production ready lens samples for our new focusable optics module.
Vacuum laminated double element achromatic lens construction utilising Ultra Low Dispersion glass, 51mm in diameter common from broadcast EVF desgn.



As our original LCDVF was designed around this type of lens we couldn't lower the level here desipite the huge price difference for the optical construction. It's so sharp from edge to edge, you don't have to look into dead center and it can be viewed from distance without edge blurring or CA.
Now we have 51mm lens for LCDeVF instead of 40mm that is still used in LCDVF products. Some info can be found here: Achromatic lens

Happy day.
