I bought this tiny TC in September 2007 for only RM575.00. Now it has cost RM1780.00 (3 times over 15 years). Seldom do I use it because the autofocus is slow. It is good for stationary subjects (as in the moon below), but not for fast action and birds in flight. The TC reduces the aperture to f/8 Max, only new cameras can do that.
My 5D Mark IV can AF at the center only. The original Canon 1.4 TC version III extenders can AF up to 61 points.
