Not happy with mine at all

  • Summary: I am so very disappointed in this product, I am sending it back. I've used it for less than a week, am a professional photographer, and have used this in a) good outdoor natural light b) with a weighted tripod and c) with a still subject and every single image is soft. Sharpness is gone. My lens that I attached this to is the Canon 300mm f/4L IS and I have the Canon 5d Mark II camera. I have used this with ISO 50 with f/stops of 5.6, 8, 11, 16 and 22.

Not good enough.

  • Summary: I bought the Extender to match up with my Canon L series 70-200. I was disappointed with end results. I'm not giving up on the L series just saving my money for the perfect fit.

Increased magnification at a cost

  • Excerpt: I have now tried two of these Teleconverters with the same results. They both caused softening of the image or reduced quality. I bought my 500MM II with hopes of being able to use this product but sadly disappointed. I tested both under many controlled tests and all results were the same.
  • Pros: Easily Interchangeable
  • Cons: Poor image quality, Poor in Low Light
