Well made converter

By Clay
Rated 4 out of 5
Date: 2026-02-05

I purchased this to use with my Lumix 100-500 lens, hoping to give the lens some extra reach. I have never had a super-tele photo lens and I am learning the limitations of a lens that is this slow and struggles to capture sharp and useable images. So, the addition of the teleconverter would obviously make this worse but I was hoping might still be useful. I feel like the converter is very well made and connected with the lens and body very well. Focus was quick and reliable but shooting at F11 and ISOs above 2000 in broad daylight just did not make sense to proceed with for me. I then did a few tests with the converter with my 70-200/2.8 S Pro lens hoping for better results and being able to shoot at F4 at 280mm. I really wasn't super impressed with what I was capturing and based on the cost of this, I decided to return. Based on the cost, I would rather spend that on a new lens. I think if you have a specific application for this converter it may actually work for you. I wanted to write this review since this item has not been reviewed by anyone in 5 years.
