Lens cap test...

What is the lens cap test? It sounds like a way to detect bad pixels...

    I lost the cap which protects the front of the lens from dust etc. But all I see are rear lens caps for sale. So what is the difference?

Switch on camera into Shutter mode. Put lenscap over lens or block it so you get a black LCD. Have a look at that first. Only a general indication but if there ARE any bad pixels on the LCD they will be visible as coloured dots. Not too important as THAT doesn't affect the pic but personally I would not put up with it - took one back for exchange for that reason .. who wants to look at spots. The CCD is the real one to look for. With lens still blanked off to a black screen set the shutter at 2 secs, take a pic then set at 4 secs, take another pic. You won't see much on the LCD so you should download those tests to your editior - Paintshop Pro, Photoshop or whatever. THEN you get a much bigger pic (black) to look at. You'll probably find at least one or two little spots, almost inevitable with many, but you should NOT get many and also very noticeably bad spots. If so , complain and exchange.

I have nikon D90 SLR. with 18-135mm lens , i want to record a video with it but a videos quality is really low .. should I change a setting or something else?

Press the menu button and go to the shooting menu (the little camera icon). Scroll down to "movie settings." there are three quality settings. Select the one you want then try a test shot. The higher quality setting (1280 X 720 pixels) uses more memory. The default setting is 640 x 424 pixels and the lowest quality setting which uses the least amount of memory is 320 x 216 pixels. Sound is off by default so if you want to record sound with your video, you need to turn the microphone on in this menu as well.

Recorded pixels 3mb download 664kb

Don't confuse pixels with bytes. A picture can have three million pixels and yet require less than a million bytes. The picture is stored in the JPEG format, which applies some data compression.
As a very simple example, consider a picture taken with the lens cap on. It doesn't require many bytes to say "three million pixels, all completely black."

Sony Cybershot DSC-S500 bad photo resolution problem

Electronic shutter in lens mechanism got bad and you need to replace complete lens assembly of DSC-S500 camera.
Of course new lens assembly would cost more then camera worth so best option is to buy new camera.

Your LCD is only a small preview screen. I have on many occasions tested a camera and viewed on the screen. When you view the image on a computer it is enlarged to a much larger image. If your pictures appear out of focus you may have a bad lens. Set your camera to the highest mega pixel rate and retake some test images. If these are blurred you have a bad lens.

Lens Cap warning on JVC GR-23EK. Obviously the lens cap has been removed!! I have seen this problem reported before but with NO definitive answer as to how it may be fixed.

This message is generated because no l;ight is detected. This normally happens because the lens cap is on. If hte cap is removved, this mesage means that the iris is stuck closed. A slight tap on the side may release it. If not, the iris assembly needs to be cleaned and freed. This should only be done by an experienced servicer.

Assuming you don't see any video through the viewfinder, it could be that the CCD has died on that camcorder. It happens, though not frequently.

If the video though the viewfinder is clear, there might be some sensor on the lens ring to indicate a lens cap, or an automatic lens cap not properly disengaging when put in record mode.

Lens cap

There may be a microswitch that detects the cap that's stuck. Take it to your dealer first, then try calling JVC for support.

A stuck pixel on the LCD is quite common. I have one on my 2020z; lot of people here would tell you the same thing. Long as it's just one, I wouldn't bother trying to get new camera. Far as the lens extension sound: It is a little loud, but a *grinding noise* doesn't sound normal. Go to a store and pick up another one, see if it makes the same sound. If not, you may have a bad camera.
