Check and see if the battery has enough power to charge the flash. If the flash is not charging that means there is not enough power in the battery as the flash requires more power than other functions of the camera. Try replacing the battery, clean contacts of the battery also and try. Let me know please. Thank you, AJ.

Wont turn off-on

Taking out the battery, when a camera acts strange, is a good thing ONLY. be sure the camera is not busy saving pictures, because you could damage all pictures on the memory card.
I'm not sure the lens was out, when it was connected to the computer. Let us assume it was. Normally, the battery should be charged when the camera is connected to a USB connector on the PC. But not all USB connectors are perfect wired. And if you use a USB hub you can be sure the battery was not loaded. So as soon as the camera came from the PC it needed full power and could not get it.
Now you removed the battery, but before placing it back in the camera, please charge it on an external charger. When you place the charged battery, and the yellow light starts flashing again and won't stop quick, you could try to reconnect the camera to the computer and see what that brings. I would have switched off the camera, before I disconnected it from my PC.

Than the sand issue. If just a grain of sand is in the lens bellow, it could serious obstruct the lens from going back. If you can see the grain of sand, you could try to get it out. Very thin needle (or two?)
But if you can't see something, don't move the lens at all.
You could damage the gears in the focus and zoom mechanism.
I wish you luck with the camera.

Sony a350. Camera motor makes grinding noise when turning on and off. Noise lasts 1-2 seconds. Was not dropped or bumped. Local camera shop said lens not camera.

A few years ago that noise was extremely common on almost all body motor driven AF lenses, and it's not exactly uncommon these days.

Your kit lens is not bad, but it is built down to a price as a get-you-started measure. It's not built as well as the upgrade alternatives and is certainly not built to last nor with repairs in mind.

Your fix is to eventually replace your lens, preferably with one which has a built in motor which will be near silent and far faster to focus. Note that if your lens has become harder work for your camera body focus motor to operate then it will put an extra strain on the motor and can shorten it's lifespan.

"Lens error" in body EOS 350D


The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.

Use these at own risk as it may further damage the camera.

Firstly , try connecting your ac adapter or usb cable.

Try holding the shutter button while switching on the camera.

Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).

Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.

Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.

Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.

Other than that , I would take the camera to a repair centre for a evaluation to see if it would cost more to repair than to replace the camera.

If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.

Hope the advise is useful. please do not hesitate to let me know if you need any further assistance. Also, please be so kind to let me know if you found this helpful.

Older lenses in new digital cameras

The camera and lenses you mention are non-autofocus equipment and have a different mount than newer ones. Your best choice for reliability, price, and ease of service would be one of the Canon EOS digital SLRs. Second choice would be Nikon D series. Minolta autofocus lenses used on the older Maxxum series film cameras can be used on the new Sony digitals, but Sony is new to digital SLRs and their track record remains to be seen.

The Power Zoom appears to be locked at 80mm.

(I just cut-n-pasted the comment into the solution so this shows up as a solved problem in searches.)

"I've found the solution!
Just goes to show that sometimes it's worth simply calling the importer's service department, who told me in 30 seconds!!
Hold the zoom twist-ring and push, or click it up or down, depending on which way you are holding the lens.
So simple; I even accused him of not knowing what he was talking about.. and of course apologised profusely when it suddenly happened."
