I've had this camera for a few years now and have NEVER had a problem with it. All of the sudden, when I try to move the pictures I took via the card / wire to the computer directly or remotely to my iphone, the most recent pictures do not show up. HOWEVER I can see every one of them when I scroll through them on the camera. How do I get my pictures out of my camera?
Based on the description you've provided, let's try testing a different memory card with the camera. It may be to where the memory card is beginning to malfunction to where it's having trouble with writing data to it. The reason why the images show up on the camera's LCD and may have trouble with transferring is due to the image we see on the camera being a thumbnail of the actual file itself and not the actual image.
Let's format the new card inside the camera prior to using it to ensure the card is initialized for use on your PowerShot SX740 HS camera. Please note that formatting a card will erase all data from the card. If the camera is able to transfer all pictures taken with it then one option on the old card is to back up as many photos as possible on to your computer. Then format the old card and then test to see if the issue is resolved.
If using a new memory card produces the same results then the next step is to suggest to send the camera in to our facility since it may be an issue with how the camera is writing photos to the memory card when a picture is taken.
