Initially very pleased, except for the fact that there is always apart from slipping when you hold it down. The catch here is so weak.
After about six months, the focus error (the images were not focused properly)
After another six months, more than one photo at a certain program the camera seehr often overexposed. (According to the manufacturer, this could be an aperture error)
Covered However, there is an operating error.
After 2 years, 3 months, total failure. No goodwill. Aperture sticks. Repair costs 119
It is merely replaced the diaphragm electronics, but not (let's see how long the holding) the motherboard.
On demand can not even SIGMA state what is the trigger number to me. (From what can be expected of a failure?)
The technician of SIGMA explained with succinct - "because not you put it" phrases
Every technical part has a MTBF (average life) --- Sigma has not heard of it. Is this ignorance or not ?!
In my opinion, a damning indictment.
Conclusion: After 2 years of complete failure
My conclusion for the next time: Dear Original CANON
MFG
