You can upload photos directly to Facebook from the camera as long as you have a WiFi connection. Detailed instructions can be found in the user manual, which you can download as a pdf file from Samsung's website.
Yes, you are right. at high zoom it first blurs then focus properly. You must be steady to get a good pic.
When you do hold tight and steady the picture is good. I find I can't hold it with two hands on the sides. I have to hold it under the camera on one side and try to steady with the other hand. it takes a little practice but it does work.
It comes with a battery (SLB-10A), a charger and a quick start guide. It does not come with a memory card--but you can get one off of e-bay. You should get a memory card with a 10 on it so that you will have the best video and picture quality. Its a great camera and I love it.
Let me say this , after receiving your question I tried it, I started recording and then pressed the shutter to take some pictures. On the camera's lower right screen a icon of a camera appears showing you that you can take 1 of 6 pictures. Now my video and pictures were sent to my phone because I had set it up that way with the Samsung app.
Yes. You will need to download Samsungs software (or App) to your computer. Then you can upload to your computer. If you are uploading videos, it "may" be faster to use the USB cable. But both pictures & video will upload via wifi. You will need the network password if required. I just bought & used my camera at my daughter wedding, to take 300+ photos and 8 videos. It worked nicely.
Happy Snapping! Stan
