What is an r28 message about? my camera will not shoot

The fact is won't focus is odd, it should always do that. Issues like this tend to be related to the storage media, and normally falls into two groups. The cards normally have to formatted in the camera and not on a computer. This is because the camera uses its own storage system. The other one is wrong type of card, or too big a card. This page specifies the SD Card type and also says it can only go in slot 2.

1 answer · Top answer: Hi, Actually no. The r28 is the count of shots available in the buffer for continous shooting..

Is this preventing you from shooting?
Normally the r-number simply indicates how many more shots you can take in the current burst before the buffer fills up and the camera has to slow down to save the pictures to the memory card. It's purely FYI and shouldn't stop you from shooting (until it gets down to r00).

Is this actually keeping you from shooting? Normally the "r" is an informative message, telling you how many more shots you can shoot in the current burst before the buffer fills. The camera should still take the shot when you fully press the shutter release button.

Download the schematic diagram to your set from here. It will have the details you want.

Glad to hear you're up and running.

First of all install the software driver of the webcam. once installed you must connect the webcam as it will be detected on the PC and will be installed.
the webcam icon will now appear as you can click to open the webcam. If the software was installed then remove web cam and uninstall before you do it once again.

r03 is NOT an error message. It indicates the number of remaining pictures that can be stored in the camera's built-in high speed memory buffer (before the camera will need to send them to the memory card). Each successive picture taken rapidly will decrease this r03 number by 1. Eventually the r01 will be on screen, and after that picture is taken, the camera will not shoot until the memory buffer has been transferred. This may take a few seconds, and then shooting can continue again.

Are the OS and camera compatible ?

Try to slide the little switch on the side of the card in the other direction. That switch is like a write protect for the card. Good Luck.
