So where to start? An absolutely demonic objective both by the quality of photos that come out by the precision and dexterity to be acquired to manipulate it. Coupled with a 5D Mark III, it offers pictures breathtaking, but against even after several sessions of use, I still have not managed to take control of the well. This is a very accurate tool that requires time to adapt to successfully fully grasp the potential of the mastodon. A great goal that I recommend to all canonists eager to challenge and very close to sublimate nature or any other part of everyday life, or more exotic! Allow all even good lighting near as quickly as we lose brightness, and flash cobra is no longer sufficient after a certain zoom level, it is a factor taken into consideration.
