Review on 💥 Enhance Your Canon EF Lens Performance with VILTROX EF-M2 Speed Booster Adapter - Auto Focus, 0.71x, M43 Camera Compatibility, USB Update Port by Jeremy May

I like this product for the price, the glass could be a bit cleaner, it makes a clicking noise when adjusting which I don't like and this seems like it , when it's evaluating the incoming light and should automatically adjust, takes a step, it's stepping into lighter or darker situations rather than gradually flowing in, which I don't like, but for its purpose I think it does the job focus automatically and it works with most lenses. It doesn't work well with the Vivitar 8mm lens. So keep that in mind.
