With the digital always shooting automatically and the machine does everything alone. Can I modify something and put something of mine? [7/8]
We have finally purchased our digital and the immediate question is: I would like to immediately use my camera, can you do it?
No. brak the urgent desire to turn it on and instead load the battery to the maximum following the instructions for use. Your camera will be grateful to it because in the future the charge will last longer. And in any case, whether it is a small compact or a sophisticated reflex, together with the car you also buy a second battery. It is an expense that you will not regret, even if, as you will read shortly, many suggest buying another only when it serves, because its life depends a lot on the date of manufacture.
But why dwell on the battery? Bèh, if you buy a car you will want to know what engine has, how much it consumes, what speed ago, what tires it mounts. With the camera it is the same thing: you will wonder how many megapixels has, as far as the shutter speed comes, what kind of use of the US exposurement ... among all this news we will also have to know how many shots we will be able to make before remaining dry with the pile ...
In any case, without unnecessarily describing the various types of batteries that are on the market know that at 99.99 % your camera will have a very modern Li-ion battery that is to lithium ions.
What does it mean?Which pollutes less than the other batteries because it is recyclable, it is a lighter third, it is less cumbersome, it has a very slow caric-scary, that is, it preserves its charge for a long time in case of inactivity (the reduction is in the order of 5% monthly), it has a high power and has no memory effect, so if it is recharged when it is not yet completely discharged it will charge the same until its maximum capacity.
The problems?It costs a lot and should never be downloaded to the end because it could be damaged, even if the cameras have a car off system that activates before the critical threshold. And then his life depends on the year of construction and not how many times the loaded or downloaded. Yes, because if it is kept at 25 ° C a completely charged Li-ion battery loses permanently about 20 % of its capacity every year; If, on the other hand, it is charged to 40 % loses "only" 4 %. So when you buy any electronic equipment, the batteries are only partially charged. Know, then, that with higher temperatures things worsen, then be careful to never leave the camera in the car in the sun ...
And finally, if inside a li-ion battery we need water or even only humidity can burst! So be noticed both in summer at the sea and in winter in the rain ...
In short, five years of average life ... and then the battery must necessarily be replaced.
Let's move on to the advice: The first is to never leave it completely download and not to keep it permanently to the maximum charge. Then try to optimize the number of top -ups by frequently and for a short time. It should also be said that the li-ion should be kept in the cold, perhaps in the fridge and before use reported at room temperature in 24 hours.
Well, the charge finally ended. Now insert the battery and turn on the camera. If you really want to use it immediately, you just have to leave the default settings, select the automatic program and shoot. Generally the wording of the program is "AE Program". In this mode your camera will take care of setting times and diaphragms and sometimes even sensitivity. Further on we will see what these parameters are and when and why modify them.
