I take issue with the statement "mediocre still image abilities". I've been taking photos like this with this camera and I think most people would agree that this is better than mediocre.

I suppose that your photo (very nice and spectacular photo, congratulation) has taken when the camcorder was in "REC" mode, according to the article review ( "It's also possible to take 10-megapixel still images with the V210, at a resolution of 4,224 x 2,376. You can't grab stills when recording video, though, and with only 2.2Mpixels of the sensor used when shooting stills, the images will involve interpolation" ).

At regular size your photo has trace of interpolation; look at the border of crater or the edge of Moon section, you can see bilinear (or bicubic) interpolation effect of image scaling method used to grab stills on HC-V210.

This upscaling action invents, literally, information to reach higher resolution, cloning around pixel by pixel group informations through convolution algorithm.

It is a nice photo for a camcorder with a 2.2 Mpix native sensor resolution, but for a camcorder publicised to reach 10 Mpix of native still image resolution, in my opinion that is not a good of quality photo.

I prefer an image taken in good quality native sensor resolution without bad quality scaling trace (like Canon Legria R series - it's only an exemple) in place of a pseudo-photo (technically speaking) taken in good quality in native sensor resolution (by camcorder system processor) upscaled to hi-resolution (by camcorder software-algorithm) losing image quality, gaining resolution.

From Italy, destroyed by EURO.

Feed your passions, have a nice day.

I would agree that the image quality is not 10MP quality. My Kodak ZD 710 (7.1MP, 10X zoom) does a better job in terms of clarity but doesn't have this amount of zoom. Also the Panasonic has a far better focusing algorithm, it doesn't lose things all the time like my Kodak does. I've tried cameras up to 24MP and they are inferior to my Kodak and to my Panasonic HC-V210. As you clearly explained, they are no longer quoting the true resolution of the sensor which sucks. Still, the image quality is not mediocre. I returned a 24MP Sony because it was worse than this camera which is pretty surprising!

Thank You for your answer (for your time and so on). The description of your adventures traces a path.

But object of your description is not linked to "image quality" (the quality of image file) that, as i demonstrated, is not so good for a 10 Mpix image; but it is linked to camcorder abilities.

So your are right: camcorder video features are "workhorse" abilities taking still image. In fact, when you move from "grandangolo" focal length to "teleobbiettivo" focal legth (as you said) the HC-V210 software changes dynamically the aperture size and also the BSI sensor's elettronic photon response without moving focus lens from subject. Panasonic HC-V210 in this situation is a top performer.

And your photo shows the perfect modulation of these gauge.

In fact look at clarity and brightness (relative to light situation) in contrast to dark side of the Moon and dark Cosmo on the back: i think that it is perfect.

But these are video-camcorder abilities (over the top in this price category).

So when you grab still image, native pixel image density (related to aperture size - fuction of focal length) is decisive and when part of these pixels is "forged artificially" unfortunately, inevitably, you lose image quality.

So, as i said in the Incipit of my previous comment, your photo is great ( i envy you :-) ); it is a demonstration of the great video camcorder lens-group abilites of HC-V210. But, according to previus explained technical reasons, image quality isn't so great.

I don't know if it is possible to take still image during video recording with HC-V210; usually in this situation camcorders grab still images in native resoltution (about 1920x1080) without upscaling image file (like a frame capture).

I suppose that (if it is possible) the relative pixels density decreases (there is no upscaling treatment too) and, at the same video-camcorder abilities, the perception of image quality increase losing convolution algorithm artifact.

Try it if you can, and post your image to complete the path.

Other suggested examples show that size does matter... of lens group :-). And we could have 110 Mpix on a 1/5 inch sensor surface but without a great aperture size focusing on a optical correlation focal length the image quality won't be exciting.

Thank you for your time. Have a nice day... and life.

What is the file format? Is it a .mp4?
