Hi! Sorry if the title is a little confusing, and I know this question must get asked a lot, but I was looking to upgrade from my old ELPH 330 HS (A camera not really built for the task to begin with) to something more modern with better features. I like to take group-shots of coins for my ebay listings, and the camera I have now has a very small battery. By the time I'm done arranging the coins for the pictures, the battery is already dead, and it must be removed from the camera and charged, which is a hassle. I'm hoping to find a camera that takes decent macro shots, can continue to shoot while plugged in, and being able to send the pictures it takes over WiFi from the camera itself would also be a wonderful bonus. I'm also struggling to get the lighting right when the subject is more than one coin, half of them are always too bright while half are too dark, but I'm guessing this is more of a lighting issue then any fault with the camera, I'll have to study up on that. Thanks to everyone for any recommendations you may have! |

My standard recommendation is the Canon Rebel XS. With its 18-55mm lens it can shoot Dollar size coins, so if the groups of coins you're shooting are larger than that, you're set. It can be tethered by USB (not wifi, too old) and the software allows you to view the coins on your (Windows) computer screen. You can run it continuously with an AC adapter that is available on ebay or Amazon, so no battery charging. |

Not sure about your budget, but my Sony A7III can be powered from USB 3.0 Type C port while shooting.

For cameras like the Sony A7III or my A7Rm4, you can charge the battery via the USB port, but the camera uses more power than can be supplied by the USB. If you leave the camera on the battery will eventually drain and the camera will shut off. So it depends on how long you plan to leave it on whether a USB-charging type of camera will be suitable. Mine will discharge over about 2 days, which is "forever" for me since I turn the camera off between sessions.

@rmpsrpms, no, I have shot tens of thousands of images in ONE session with my A7III, no problems at all. If you have problems, check your how you use it and your USB port.

It's not so much the number of images, but the time. Or perhaps you are plugged in to a high current USB hub or something?

OK, I did not mention that a 10K session is about stack and stitch and every shot takes 4 seconds, wait 2 secs for rail to stablize after moving, hold it for another 2 sec before moving again, adding in time took to capture each image, we are talking about 12 hours of operation per session. So number of images matters and a lot in my case. Yes, I am using 65W USB power, well, being a nerd, I thought that is given.
So yeah, I see some disconnect here :-)

Well, my point was that cameras like the Sony's can't actually be powered by the USB. The USB is used to charge the battery, and the phone gets its power from the battery. It's very convenient for folks who run the camera in sessions, then turn off when not in use.

I am confused, I said that I can plug my Sony A7III into a 65W USB power device, run it for 12 hours shooting a picture every 4 seconds, and you are saying "Sony's can't actually be powered by the USB", what is going on?

Is your battery installed?

Yes, battery is installed, so far, after few years (do not remember), I have only taken out the battery twice, I think I lost the charger for it :-) I leave it in the camera, charging the battery via its USB Type C port, or just use it with it plugged in.

Have you ever tried running the camera powered by the USB port, but with the battery removed?
