I have nikon d40 with 18-55 lens. when i press capture button there is a noise(i think inside the lens) and r07 displays in the viewfinder at right hand side corner. is that a problem or its normal?

• The "r07" message on a Nikon camera typically indicates the number of available shots in the camera buffer. It's not an error but rather an informational message. The number "r07" means that there are seven shots available in the camera buffer before it fills up. This is a normal part of the camera's operation and doesn't necessarily indicate a problem. It's more noticeable when you're shooting in continuous or burst mode. If you experience issues beyond this, it's advisable to check your camera settings and consult the camera manual. https://caranddriver.com/

Did you try pressing the display button several times? in both viewing mode and record mode? Cycle through all display modes, s you get used to the button, so it does not trow you off when it happens again.

Inside the camera is a mirror which reflects the scene up to the viewfinder. It flips out of the way when you press the shutter button. When the mirror flips up, the shutter opens and exposes the sensor. When you look inside, if the mirror is stuck in an up position, you will not see anything in the viewfinder. However, the mirror is super delicate....do not touch its surface or try to force it.

I don't know what you have tried but, the Live View button is just to the right of the LCD screen and just above the "OK" button. Pushing this button takes you into live view, it's not instant because of some of the internal functions the camera needs to do before displaying on the screen. Might take a second or two. By pressing the button again takes you back to "normal" viewfinder.

Setting auto focus mode for the Live View is accomplished in Custom Settings Menu a 7 I think.

Oh, don't forget to take the lens cap off cause all you'll see is a black screen

I have the same message r07 on the same camera & lens combination. It is an lens error message that the lense will not focus. You can manually focus the lens in the auto mode and the camera will allow you to take a picture. I have been told it is the MR unit and cost of repair around $135.

Hi there its happens when the lens not ready for work. Some how its not able to stable his focus method. That's why its stuck & you get the noise. There is a chances of lens guide pin disturbed or damaged & thats why continues failure. Its mean he inform you there is a system error. So please visit the service center for repair that. Its a very common & repairable problem. Thanks.

i think the f-- code means its not recognizing your lens correctly. make sure all the contacts on lens and camera are clean. the r11 is the buffer. nothing to worry about. The number of images that can be stored in the memory buffer at current settings is shown in the exposure-count displays in the
viewfinder and control panel while the shutter-release button is pressed. This number is updated as photographs are transferred to the memory card and more memory becomes available in the buff er. If 0 is displayed, the buff er is full and shooting will slow. Shooting can continue up to a maximum of 100 shots.

you can get the d80 manual here if you dont have it

Have you tried formating the memory card? R07 means it has 7 shots in internal memory. Since you have already pressed the reset through the small hole in the front, if formatting the card does not work, try downloading the latest firmware from Nikon and installing it.

I have the same camera, but never had this problem. I think there's something wrong with the shutter mirror or worst, the sensor. Did the viewfinder blacked out when you press the shutter? I think you need to bring it to Nikon repair shop....

Mine occasionally does this as well, but only when trying to focus on the left side of my viewfinder. I found there is a piece of dust on the sensor in just the right quadrant that prevents it from focusing. Try setting your focus settings so that you can press the left or right buttons to select the focusing quadrant (left, middle, or right). If that fails, you can always manually focus.
