## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome when it worked. But it broke after a month of light use. UPDATED
*by S***S on December 7, 2024*

It did what it said it would do...for just over a month. Then it stopped functioning just after the return window. I wanted to love this product, but it no longer focuses and no longer works. $400 paperweight.UPDATE!So it turns out it was a firmware issue. Found instructions to roll back the firmware, set the f stop to 99, press the back focus button and take a photo, set it back to F 2 and it worked again! Find the instructions online. While annoying, the fact it works again brings it back to 5 stars. Has not given me any issues since.

### ⭐⭐⭐⭐⭐ Awesome product!
*by K***E on August 27, 2023*

Not sure what’s with the negative reviews but this works perfectly! With these pictures, I’m using a Sony a1 with a 35mm Summilux lens from Leica. Obviously the photos taken from my Leica are a little better but with a little editing, the photos will be near identical. I put the Techartpro to the test by taken pictures of moving objects and they didn’t come out bad at all. I would say for 400$, it’s worth the price hefty price tag. One thing I would change is having a clear instructions manual. It’s confusing and would recommend looking tutorials on YT

### ⭐ The electrical connections are prone to be scratched and rendered it useless.
*by R***R on February 7, 2024*

I did not buy this on Amazon but a used one from elsewhere. On receiving it I was excited to try it on my Sony camera but it did not work. I took it out and noticed four of the electronic connections were scratched. It did not happen to the older version on the same camera. I could not figure out what caused these scratches. I believe it is a common problem for this new version as the photograph of another one sold as parts had the same scratches! I believe if you twist it the wrong way would cause it to be scratched. Now I understand why there are more of this new version sold for parts than the old version!
