I have been to all my Canon (D) SLR cameras attached a battery grip. The main reason was the better handling of the camera, especially in vertical format photos. So I have now bought after purchasing the Canon EOS 600D these additional handle, bundled with two spare batteries. , The handle adjusts the EOS 600D like a glove, it merges with the casing. The gap dimensions are equal to zero, the color and surface structure are no different from those of the camera. Visually all of a piece. It rattles nothing, nothing wobbles. The slots for the batteries fit perfectly. , Cultivated the auxiliary handle to the tripod socket of the camera, as with all previous models. The screw has a good grip and you can tighten the handle firmly. Do not be afraid, under the handle is a tripod socket installed, you do not have to do without his tripod. In order to grow the handle, the battery cover must be removed at the camera before. With the EOS 600D This is clicked and can be solved without difficulty. Thus, the lid is not lost, there is the handle a marked (!) Place where it can be stored between. , Technically, the auxiliary handle provides the same options as the original. I have a second release button the cheaper is the vertical shooting grip as the shutter button on the camera itself. The buttons for AE lock (* key) and the AF-point selection are available as well as the button for the exposure compensation (Av) to the Main Dial. All these features are available when the switch on the back of the handle is set to "on". , Inside the handle can be accommodated one or two batteries (original or replacement). If two batteries used, the term will be extended the same considerably. Alternatively, 6 AA batteries (or AA batteries) can be used on a second slide. Which duration is reached with the camera, depends to a large extent on the performance of AA batteries. Reference values I have not yet. , After reading the other reviews I had feared, the battery grip is a 'stink bomb'. No, it is not my. A slight plastic odor was noted when unpacking, the handle itself has the environment is not burdened "with any exhalations". ;-) , The two batteries of the bundles are labeled with 1400 mAh and bring order (theoretically) more power than the original battery by Canon. This verify is difficult for non-professionals. It should be noticed when using in longer battery life, only depend on many factors which are known (display, look up the pictures, Image Stabilizer, etc.) from and can ever deviate from charge to charge significantly from each other. , Conclusion: In the bundle offered here the additional handle for the Canon EOS 600D is a best buy. , A tip at the end: I have attached the strap to the right eye of the camera and to the eyelet at the additional handle. In order to wear the camera vertically and focus changed, the camera tilts mE so strongly toward the lens.
