Camera freezes 18secs after switch on.

I am assuming you get this error after shooting a picture. Try formatting the memory card in the camera instead of the computer.

Looks you have a slow memory card. Nothing wrong, when you use class 2, 4 or 6 in your camera, but it will slow things down sometimes. Not only for sports shooting, 5 or more frames a second, you need a fast card. For Video it is advised to chose fast cards to. Some cameras only manage one shot a second, and that will become word, when a slow memory card is in the camera.
I don't say this is the reason, I only say this could be the reason.

From your description, it seems something wrong with the connection between your card and camera.
As a suggest that, you can use a memory card reader to reduce the consumption of your camera accessories. If there is something wrong with your memory card, you can replace it easily and with low cost, but if there is something wrong with camera accessories, that's more trouble.

ERR means camera error and CHA means this card cannot be used. You are probably getting the CHA error because of a camera malfunction. Try removing card and batteries with the camera turned "ON", the press and hold the shutter release for approx. 30 seconds. Replace battery and card. If your D90 has a "reset" button on bottm of camera, press that when batteries are installed and camera ON if the first doesn't work. If it continues, then Service by an authorized Nikon Service Center is advised.

Hi, I solved the problem, it appears the memory card was corrupt. When I removed it and switched on the camera it worked perfectly. Not sure why this happened!! I'm just glad my camera is working again!!

Thanks.

The r05 is not an error. It's simply telling you that the buffer has room for five more pics. It's only a problem when it gets to 0 and stays there.

As to the other error, I'm afraid I can't help you there.

It turns out that supporting the camera while taking a shot can impart a slight twist on the seated lens. This twist is just enough to cause the camera to think that there is no lens installed .. hence the error message. Solution (provided my Henry's Camera experts) was to reseat the lens by reversing the twist. It has since happenned twice and each time recovery was effective .... Keith

Try these procedures.

dear hydet

use 'Program Shift'. This will change the values for both aperture & exposure, but keep the overal exposure value correct. Eg if the standard values are 1/60th of a second at f5.6, then rotating the dial in one direction will change the parameters (first) to 1/30th & f8, etc, and turning it in the other direction will change them to 1/125th & f4.

oke, post in me back


thx

Yes, please turn off the camera when changing lens, make sure on the lens is on its full aperture if you are doing auto. if doest not work to make is test turn the camera on the manual mode and the lens too.
If your lens is new there should not be any problem, if you bought the lens used make sure all the points are clear not rusted. some time when lens fall of it breaks its points inside.
