I got my EX-V8 on Saturday. No memory card so I am just shooting with the built in 12MB of RAM which rather limits my picture taking but here are some samples on my blog:

There are some 100% crops there for pixel peepers but just 2MB mode.

I like the camera so far. Decent quality. Not Canon or Nikon but better than my previous FujiFilm E900 except when pointed into the sun - lots of lens flare.

Cheers

Walter,

I enjoyed your blog. Keep us posted on how you do with the V8.

Thanks for sharing your findings of this camera. I have one now and only two days so far and found that I really like what it does and the quality of the pictures are above average to good.

For what it is I find this a remarkable feat for a camera this size.

Mahalo,

Tom

Hello pubwvj,

as there is no decent Casio V7 video footage on this website yet, could you maybe upload using http://www.megaupload.com some848x480 video footageand some 640x480 video footage ?Both at 30 fps and using the best available settings.

I have clues that the Casio V7 video quality isthe best in the640x480 category, with stereo sound, BUTI also have clues that the 848x480 setting is delivering bad video quality. So if you could shootthe same scene using the twodifferent settings, that would be very useful.

I have no idea how video is exploiting the CCD. I really doubt that consumer-gradeCCDs designed for digicamsare now capable of outputting 30fps in full resolution. There must be a kind of CCD subsampling at the heart of the process. Likemerging pixels ... but the RGB Bayer filter doesn'tallow this easily ... because if you join pixels using 2x2 or 3x3 readouts, you are mixing different colours ...This makes meperplex.Anyway, I feel that the video capture at 30fps may remainoptimized for a 4:3 output format, maybebypassinghorizontal pixels or entire verticallines (bye-bye sensitivity), soone should rememberthis tricky readout process isdone in the 4:3 format of the sensor.

Just as example :
http://www.datasheetcatalog.org/data...y/a6802623.pdf
This is not an up-to-date CCD sensor, but the High Frame Mode section is still quite instructive. I bet the same rules do apply nowadays for 7Mpix, 8Mpix and10Mpix CCD sensors that we can find in Casio Z7, Z8, Z100, Z200 ... and many other digicams.

Realizing this, there is a risk that the highly optimized and tricky videocapture done on the CCD is always 4:3 ... and maybe always delivering 640x480 pixels and no more, so if one wants to output a 848x480 format, there is no other choice than applying a post-processing consisting on top and bottom cropping at 640x360 (only 360 lines resolution) and then upscaling by a factor 1.33 in all dimensions in order to "fake" a 848x480 format.

I think I can see this upscaling process in this 848x480 video here, coming from the newest Casio Z-200. Look at the front of the Audi car ! The front grill and frame aremoving crazy. I bet this artifact doesn't show when shooting at 640x480.

http://www.megaupload.com/?d=PGAIZ9UL

We definitively need to know if some digicamslike the Casio V7, V8, Z100 and Z200 are "faking" the 848x480 video, with ugly results (because ofupscalinga 360 lines video),while providing excellent 640x480 videos.

So, please,can you upload some scenes filmed both on 848x480 and 640x480 ?

As soon as I get a chance I'll do that. I'll need to explore MegaUpload too.

Yesterday I got some video and still footage in dim light (7:30 pm) of moose. The stills are on my web site at:

http://sugarmtnfarm.com/blog/2008/05/moose-galore.html

As soon as I can I'll upload the video of the moose too. Then when I can I'll do your tests.

Cheers

I haven't had time to do the high res video tests - maybe this week when we have some sunny weather.

I just edited together the moose video footage that I shot in the evening - low light conditions. See:

Two images showing the Best Shot Sunset Scene mode (captured through the windshield in the evening from a moving vehicle):

and a close-up in macro mode on a bright overcast day

I'm still liking this camera. More and more, in fact. It is an excellent tiny pocket shooter with full manual controls. The image quality won't replace higher end cameras but it gets those shots when I never would be carrying a bigger camera.

Cheers
