More Novice Info VX2000 and GL2
 
Traveling two days this week, but wanted to note that I did finally think to look at data code readouts ; just a quick summary is that in low light and dark light the GL2 lense was at max (1.? forgot to write down) and gain boosted between 12 and 18 db in many cases; VX2000 maximum iris was 2.6 with no gain under same lighting. However, given low quality of TV and my untrained eye at first glance the 12 and 18 db boost of GL2 was not an obvious problem to the casual observer. Again, this happened in full auto mode for both cameras. One other "adjustment" made was ND filters were switched in as prompted by camcorders in outside shooting.

Novice Compares VX2000 and GL2
 
Adrian

Thanks for the correction. I got the misinformation from a feature check table in the UK's Camcorder and DV Movie Maker Mag, Sept. 2002 edition, unless the European version is actually different. Another recent buyers guide (North American) indicates that they do both use the 1/3 inch CCDs but Canon at 270,000 pixels per CCD versus Sony at 380,000. You referred to this in general terms in your post. Do you know what the effect is, or is intended to be, of more versus larger?

-------------------

Then you were far from stressing the VX-2000 in what was, in effect, for it, bright light. The VX-2000 lens opens to f1.6 and it has 18 dB of gain to play with. That is a massive low light advantage with regard to picture quality in scenes that are darker than what you shot in. The darker the scene, the more obvious the differences are. Not only because of the sensitivity but because of the very low image noise levels. Much better, for example, than with my DSR-300.

It is unfortunate that you were not allowed to optimize the performance of each camera through manual settings. As it is, you really don't know how good the cameras really are at their limits.

It is also likely that by not resetting the white balance on the camcorders whenever you changed light levels, you probably contributed to the color cast in the lighter colors.

Congratulations for taking the time and expending the effort to test these two cameras.

BTW, it is hopeless to consider and compare CCD size and pixel count without knowing how much area of each CCD is used for 'real' video imaging. There really is no clear indication that the 1/3" CCDs are physically 1/3" or that their active area is 1/3". Without a value for individual pixel area and understanding the camera's DSP (image processing) technology, one can only test sensitivity to compare

Pictures with VX2000
 
Please have a look at these pictures taken in Alaska.
I was surprised at how good they printed for a video camera.
I have seen pictures taken with the GL2, but frankly I prefer these. What do you think?
The only reason I would like to have a GL2 is for the 20X zoom.
Thanks,
Michael

I don't mean to be rude, but what pictures am I looking at?

Very nice pictures---did you do any manipulation in Photo Shop or some other image software???

Bryan Beasleigh December 2nd, 2002 08:26 PM

Very nice pictures. Time for me to buy a memory stick and take that trip to Alaska. ( I 've never used the still feature of the camera)

Jeff Donald December 2nd, 2002 09:16 PM

Nice work Mike. Those are images to be proud of.

Re PhotoShop
 
Hi David,
The only thing I did was put some of them through auto retouch in film factory, (mostly for the exposure) but most of them are about the same straight out of the camera. I find it usually does a good enough job for slide shows.

Quality Checks for VX2000
 
Amazingly (given time it has taken me) will actually buy VX2000 but limited return privileges. Besides going step by step through manual and checking each function (including I guess looking at troubleshooting section to see what could go wrong), any suggestions on particular things to look for that could be wrong with camera but not immediately obvious to the novice (me)?? Just as an example only, I have seen posts on "hot pixels" or whatever and I wouldn't know what a hot pixel was if it burned me or what to look for to see if my particular camera had a problem. Maybe there is a published "checklist" somewhere?? Thanks for help.

Mike Rehmus December 4th, 2002 07:29 PM

I think the best way to test the camera and learn the functions is to go through each paragraph in the manual and operate the camera as I read. That way I check out the functions and learn to operate the camera.

Then I go out and shoot with the camera. At least several hours worth of use.

Hot pixels are really apparent. They are the white dot that appears in the viewfinder and the image that don't move when you move the field of view. These usually show up at higher gains so you can place the camera in a dark room and run the gain up to check.

If you live near a populated area, you might try and find another VX-2000 user, get together and compare camera performance. Usually, camera failures are rather spectacular. My PD-150 developed a fault within 2 weeks of its purchase. The steadyshot would sort of slam into its stops and you could hear, feel and see it. Sony promptly repaired it as the company from which I purchased it only covers the first 7 days (B&H Photo Video).

The worst thing you can do is unwrap it and set it on the shelf. Use it a lot for a while. That way, if anything does go wrong, it will likely do so in the first 90 days when Sony warrants both parts and labor.

Set the camera on a tripod and jack it into a TV. Run through each function and feature. It's a good way to learn what the camera will do.

The ultimate color setting on the VX2000E??
 
I have a VX2000E which i film with, I use the Custom Preset settng to adjust the color, sharpness, gain and so on...

I know I can adjust the color levels in Premiere/After Effects, but what do yuo guys have adjustet on your VX2000?
You use the CP setting?
I would love to know or get a few tips on the setting which give the most realistic look, maybe even a bit of a film look?:)

Thanks
