Eos 7d Rumors
battery consumption in a digital camera is worse than in most film cameras because of its onboard electronics. The thing to remember the battery is the word not only means a cell, such as some digital cameras need about four AA batteries. And the four batteries can take about an hour or so of shooting. All this is compounded by the fact that the batteries always a number one concern for any photographer to keep the device while Performer – cheap efficient, high capacity, rechargeable, and the environment.
Two very safe for the environment are the NiMH (nickel-metal hydride) and Ki-Ion (Lithium Ion) batteries that are cheaper to use than traditional alkaline batteries. It is an alternative the 15 million alkaline batteries that are discarded after single use. But despite the battery you are using, we can not predict how long our equipment Digital Photo headed by simply knowing the rating of the battery. An example is AA alkaline batteries that are rated over 2500 mAh NiMH only planned for 1200 to 1900 mAh.
These figures are behind many photographers mistakenly believe that alkaline batteries have more power than NiMH batteries environmentally-friendly. But for sure the batteries, or NiMH batteries Camera Li-Ion series of three to four times more than alkaline batteries can offer their full capacity if the device is used slowly.
A NiMH battery with a rated capacity of 1,800 mAh take more pictures of alkaline batteries is in the mAh capacity of 2800. The Digital cameras placement high power drain all the batteries, which makes rechargeable batteries NiMH or NiCd (nickel cadium) batteries better. Lithium batteries also work, but they are much more expensive and usually can not be cashed. Duracell Ultra and Energizer Advanced Formula battery may also last longer in digital cameras – but only 30% more – which means an increase of 15-25 images at a maximum of 20-40 images.
Many photographers, rather than alkaline batteries a freezer, thinking recharge or prevent them from sinking. The fact is that alkaline batteries lose power with less than two percent per annum, or cooling mode Freezing does not make much of difference. But if they are kept in a temperature higher lose their ability much more – 5% per annum to 85 degrees, or 25% to 100 degrees – who require a cooling heat Outdoor.
NiMH or NiCd batteries lose power every day at 70 degrees or more, so they Refrigeration slows this decreases, while the gel to maintain its power in the ability of 90%.
Another important step is the charge of the rechargeable battery. A statement base in a technical sense, indicates that "a battery which is always slow charged will last longer than that at full load.
Many rumors have said that the battery fast charging, NiMH and shorten its life, but if the battery charger that is specifically designed to charge Bought faster than NiMH batteries do not be a problem, which reduces their power is more frequently occur with a night "shipper based on them after deleting a number of hours. What if you forget and they pay more than they should – the battery life is reduced is what happens.

60D comes in the short term?
Canon EOS 60D is rumored to be in the short term? and greater than or equal to the Canon 7D? or center between brother and T2i 7D?
Potentially, the next week, according to a representative from Canon. X0D most often midway between x00d and xD. If I say Random 18mp sensor, the body more resistant (eg, 7d, unlike T2i) and video mode (a first for the x0D organs.) Course with a price between two, (maybe a little over a grand?)
