If you want to start taking indoor photos in low light at night (9 pieces of 10 is generally weakly or partially lit), this flash is for you. The ideal distances are less than 7m bounce_flash knowing that the principle is to flood the ceilings / walls of light to avoid shadows and burn the nearest light areas. This directional TTL flash on a half-full sphrère quazi is multi modes (I have not yet explored all the features) and uses the reading of framing your TTL target to adjust its own focus. The automatic zoom feature is very valuable for this price range. Usually when the batteries are full it allows a burst from February to March and photos will fire the next capacitor charging one or two seconds later. I have not yet tried the USB update firmware. I regret that Metz had not built a discharge system (resistance / heat dissipation) of the batteries to cycler seen that when the intensity and intention chuttent, partially discharged batteries are recharged without being able to avoid the linked memory_effect the NiMH technology which automatically implies an important chutte the number of possible déclanchements successive loads. This system does exist on other models in other brands? I doubt it. I also regret the thin plastic clamping ring which gives the impression that the thread will release if I squeeze too hard. So far she accepts a powerful tightening ... but the plastic box that then it dries. I would have liked in the box a diffuser sock, but this is probably the objective of the folding screen I have not really tested tests. It is winter and the nights are long, it's good. A full charge 4 AA NiMH 2700mAh, I obviously managed to get well in excess of 150 shots. The few failures I had kept to its use of poor communication between lens and housing (as the case of the flash CPU transfers the info collected by the CPU of the lens) - since resolved by cleaning the contacts housing. The Mecablitz is a very honest price for his product for any amateur photographer who refuses interior photos washed out by the flash of their housing. A tip: make a new white balance from a test photo in EVERY room as your flash floods ... because despite a spectral temperature of the flash close to that of natural light, the light that bounces off the walls / ceilings [according to distance / orientation of the lens] spring colored by the surface against which it bounces. Given that in France, we love smoking and blanc_cassé dulux, Caucasian faces emerge more Asian than Scandinavian. Alex.
