Customer Question
Hi, I have a...

Hi, I have a Nikon D7200 camera and yesterday I started to get this r42 error with the 18-55 zoom lens. The lens would not focus nor would the shutter release. I do not know how this started nor do I know how to fix it. Any insights would be most appreciated.

Technician's Assistant: What's the exact make and model of the camera? And can you guesstimate how old it is?

It's a Nikon D7200 and it's about 18 months old.

Technician's Assistant: How long has this been going on? What troubleshooting have you tried?

It started yesterday but only with this lens 18-55 zoom. I pulled the battery, SD Cards, reset the lens to make certain it's on Auto focus.

Technician's Assistant: Anything else you want the Electronics Expert to know before I connect you?

As I mentioned, the other lens I use 70-300 zoom, this error code does not appear.

I though r error messages were a buffer remaining message... Can you take a picture successfully and if so does the number reduce?

The shutter does not release.
Camera and Video Technician: Neil, Camera and Video Technician replied 11 months ago

Have confirmed its a buffer issue... r and then a number is ***** buffer problem usually caused by a problem with the SD card, if already using a class10 card then try removing all your photos from it and then reformat it... Its possible it has become fragmented and slow and when using the camera with a wider lens (which means more information therefore more data to process) it is overflowing the cameras internal buffer..

Ok I'll give that a try. Reformat the SD cards. Thanks.
