It's been a month since I bought the equipment. EOS 550D - TAMRON 18/270 - 270EX Flash and a few other small items. I press correspondent and I'm at 7800 pictures. I have not yet taken the device fails in some way ..... whatever. Goal goes everywhere with a lack of light strand offset by "forcing" the unit up to 6400 ISO. TTL auto flash. This is great: sports pictures (basketball, football, monte carlo rally, IRC, tennis), pictures of inside and outside group poses on stages (TRI YANN, ...), concerts, bougers, blurs, everything is OK. By cons, flash wears very quickly normal batteries. Use rechargeable. I have more now only one device (with a supplement in LUMIX compact) and more in the Amazon Photo backpack !!!!! I do not get enough. Items in their complementarity to recommend for those who do not want to bother with a canteen equipment, objectives.
