I have long struggled with the price, but I must say it was worth it. Until then, I did not want to work with a flash. If I have seen so many flash images, but I realized you can not skimp here. Photos with high ISO values but were just too noisy to me. Now about my impressions of the Canon 6D. - With a single charge you manage about 250-300 photos - Rooms are very well lit even at indirect lightning - Very well made - The operation is a breeze - The interaction with the camera is perfect
