Review Tele Photo 2x Zoom Extension Lens Converter

In this video I tested the aftermarket 2x Telephoto extension lens / converter, than claims it can increase your focal length by 2x.

It can, but will degrade your image too much, that it’s almost unusable on long end. It will increase your lens weakness as well.

Solution: buy a cheap old zoom lens, it will result much better images

I thought it was bad, but that much was a surprise.

Julius Doe says:

I have a 2.2x with the same markings except for “VIVITAR HD4 MC…”. I bought it because of the brand, but have the same issue with my 55-210mm SONY lens. Manual Focus or not. Was cheap on Amazon.
