Hello, I'm a user of the G system for about 2 years by now. I've started back in 2011 with a G1 that I still keep as a back up camera. I've always shoot using RAW+Fine JPG setting with my G1 and now with the G5. Now with the G5 the time the camera take to record the pictures to the SD card is annoying me. If I shoot about 4 or 5 consecutive pictures the camera blocks me from shooting for about at least 20 seconds. No matter I press the shutter button it wont allow me to take any more pictures until it processes and saves the pictures to the SD card. This makes me lose a lot of picture opportunities. It happens on single shoot mode, so you can imagine if you set to burst mode it could get even worst. I take a series of 5 or 6 photos and better wish I got one of them good enough because I may not have the chance to try shooting again right after that burst shoot. Mainly I do bird photography and it is very frustrating when I take 4 or 5 pictures and then the bird stands right the way I want... but pressing the shutter button one more time will do nothing! It happens that even about 15 to 20 seconds or more after taking some photos when I switch to Play mode the camera is still processing the images and does not allow me to review the pictures. My G1 camera also have some limitation regarding the process and recording of information to the card due to the buffer of the camera, but not this way. It rarely let them down. I've gave up using a Class 10 - 20MB/s SD card and start using a Class 10 - 45MB/s SanDisk Extreme SD card but the results are the same. I don't see any difference... Did Panasonic increased the pixel count of the sensor (and consecutively the file size) but not increased the buffer processing power? I'm considering change to a Olympus OM D because of this limitation. Are any other G5 users experiencing the same, or this could be a malfunction of my camera?
