Is there really no way automate a DSLR to shoot every 24 hours without having to pick it up, charge/replace its battery, and put in back on the same spot ? Canon and Nikon cameras can be connected to AC power by means of an adapter that fits in the battery slot. For example, Canon DSLRs that take an LB-E6 battery (like the 5D II, 6D, and 7D) can use an ACK-...

The main reason is because the batteries for MILCs are almost universally smaller than DSLR batteries. Some mirrorless batteries: The LP-E17 battery for the Canon EOS M5 has a 1050 mAh (milliamp-hour) charge storage. The NP-FW50 for the Sony a7R II has 1020 mAh. DSLR batteries: Nikon's EN-EL15 battery (for D500, D600, D610, D7000, D7100, D750, D800, ...

LCD screen and any wireless features like Bluetooth, WiFi or GPS would be the heaviest drain. This would be followed by flash/focus-assist then auto-focus, image stabilization would probably be next. Just being on (or even off and providing enough power for the display counts) would be a minor drain. Keeping the camera on between shots won't do too much. ...

A mirrorless camera consumes more power mostly because the circuitry is constantly running. Both the sensor and EVF or LCD have to be powered continuously in order to maintain the Live-View which is necessary for framing. In contrast, a DSLR can even be used to frame while powered off. The viewfinder requires no power at all and the status line below the ...

Do NOT do this. Please read this post from Electrical Engineering SE regarding Li-Ion battery. Li-Ion have one failure mode. Fire. And it's not a normal, lighter fire, or even a stove fire. It is a fire-that-burns-in-a-vacuum fire. It's a fire-that-reacts-with-water-and-air fire. Li-Ion is not the battery type to play around with. They are dead not ...

Do you have any other basis for comparison, does this power consumption rate sound expected and acceptable? I see similar results on the 6D: GPS uses a lot of battery power. It also uses battery even when the camera is otherwise idle. Turning off both GPS and WiFi will give you significantly improved battery life. That doesn't mean that GPS isn't still a ...

This is not right. I'd try Nikon again. Explain that you understand that the battery is a consumable that might not be good in a year, but that it is brand new. If that doesn't work, take it back to the store you bought it from. And if that doesn't work, open a dispute with your credit card company (on the grounds "they sold me a lemon and won't take ...

Not sure how this fits in with e-ink, but there is a product category called "trail camera" that might do what you need. These are cameras designed to take pictures in the dark or light in response to motion and most should easily meet your one week power requirement. Although most of these cameras store the images on a local card, there are models that ...

The K1000 needs darkness in order to turn off the meter. Changing the ISO, shutter speed, and aperture will just change what the meter is looking for to balance the needle. The circuit that controls whether or not the meter gets power is controlled by a light-sensor that watches for light on the focussing screen. If sufficient light is present (EV2 @ ISO100,...

No, cameras can not be powered by a USB port because they typically require more than The 5 volts maximun available from the USB port.

I have a 6D and a 5D Mark IV. I haven't used the 5D enough to profile its battery life, but in my experience with the 6D, GPS causes maybe 15% battery drain per day. And with the 5D Mark IV, it should use much less, assuming you take advantage of the new "mode 2" behavior that turns GPS completely off when you switch off the camera. So in a three-hour ...

NiMH (which is what eneloop are, not NiCd) won't explode in heat you can survive in, but may suffer. The most likely effect is a significant reduction in capacity, most of which will recover on cooling and recharging. Reducing the drain on the flash batteries will help (e.g. by swapping between sets frequently, or only using the flash as much as strictly ...

From the D5100's manual (page 81), the 600+ images is by the CIPA standard, and does not include live view — just 4 seconds of review for each image. It's not surprising at all that real-life usage is much less, particularly if you are using live view constantly. Sadly, I think your options are: Change your habits, or Pick up some spare batteries.

An unplugged charger may, or may not, discharge the battery if it isn't plugged in to the wall. Depends entirely on the charger's circuitry and may change without notice, even if it's exactly the same model of charger (the model number guarantees it will charge the battery. It doesn't guarantee how it charges the battery) However, if your battery is ...

I have the Canon 7D Mk II and I have seen it last upwards of a month if not longer on standby without the GPS on. I don't know what the official length of time is from Canon, but I find it barely uses any battery when in stand by from my experience. Even the one weekend I left the GPS on, as long as the GPS is locked in, its not to hard on the battery. If ...

First, we need to understand that your battery will lose some of its charge even when stored outside of your camera. This is what is referred to as "self discharge" or "shelf life." Rechargeable batteries tend to self-discharge at faster rates than their non-rechargeable alkaline counterparts. Historically, rechargeable Lithium Ion (Li-ion) batteries are ...

Nowadays camera batteries are (almost) invariably LiIon (Lithium Ion). There may be a very few specialised exceptions. LiIon capacity falls as you approach 0 C - it's not that they discharge quickly as such, but that the capacity falls. LiIon is unlikely to suffer permanent damage under charge or discharge down to 5 degrees C. Discharge is safe down to ...

It doesn't discharge very quickly. Li-ion and other batteries actually increases the internal resistance and makes it discharge slowly. As for your question, while keeping the battery on low temperatures can decrease capacity for some times. I don't think that it'll permanently damage your pack. You'll just have to recharge it again in "room temperature". ...

The number quoted is usually the one achieved according the the CIPA standard. This is a procedure where the camera takes a few shots, is power cycled between every group of shots and flash is used 50% of the time. As you speculate, not all actions drain the camera equally. Based on experience of using hundreds of digital cameras of various brands, the main ...

NiMH batteries have a fully charged voltage that is lower than a standard alkaline AA. A partially discharged NiMH battery (or an NiMH battery that's been stored for a while) will have an even lower voltage. For occasional use I'd recommend getting some Lithium AA batteries. They're relatively expensive, but their energy density is high, and their self-...

The possible reasons for such behavior can be: You preview the images you take too much. Using the LCD screen can exhaust the battery You use too much live view. Again using LCD is not good for battery Your lens have image stabilization and you half press the shutter too long. You have defective battery

Yes, having GPS turned on will drain the battery pretty quickly. This is true of any camera, not just the D5300. Not much you can do about it if you want your photos GPS tagged. If you turn GPS off, you should find that the D5300 has pretty much the same battery life as your D3100: 600 shots for the D5300 vs 550 shots for the D3100. Camera battery life is ...

Only Lithium batteries may explode if they are used while overheating. For NiMH, overheating may damage them permanently in a way that will shorten their lifespan, but nothing more. As for NiCd, I think nobody sells this crap anymore because it's really bad for the planet. For precautions of use, hide your gear from the sunlight as much as possible. It's ...

You'll likely need something with a little higher amp rating than the power pack you have linked. 600W at 110V is only about 5.5A. The peak rating for the 110 VAC outlets is 700w, which translates to about 7A. You probably need about twice to three times that much peak power capacity to tolerate the peak current required by the light at the start of each ...

From FAQ at http://www.paulcbuff.com/faq.php Q. What is the average current draw of Paul C. Buff™ flash units? A: Einstein™ units draw an average current of 5 amps during recycle and AlienBees™ and White Lightning™ flash units draw an average current of 6 amps. This means that if a light were fired every time it recycled, the average current draw would be ...

I have been storing my spare battery in the unplugged charger for the last 6 months and yes there was depletion of the charge ( 5% per month). I would have to do an experiment to find out if there was less depletion by storing it out of the charger. I never thought about whether it was safe or not until you asked the question. I have not had a problem with ...

It should not cause any damage, just the battery will be slightly depleted if left for extended periods of time.

For a camera battery, the best advice is possibly to just not worry about the battery. Charge it when convenient or when you require it - simple as that. As Count Iblis has stated, lithium batteries do not suffer from a "memory effect" - if anything, a complete discharge would be worse than charging when full. The optimum charge level for storage is around ...
