How about the old frog 60mm 2: 1+0 macro lens?

The magnification of the old frog's 60mm2: 1 macro lens can reach twice the parameter, which is great (I measured it with a ruler and checked it). No obvious problems were found in image quality and distortion, which should be said to be good. It feels good when you focus. The processing should be said to be more exquisite. However, the focus and aperture adjustment of this lens are manual (so the price is very cheap), and there is no lens at the front end of the lens barrel. When the focus is adjusted, the lens retracts into the lens barrel, and even the guide rail is exposed. Although it does not affect the shooting, it is an unprecedented style. In order to prevent dust from entering, I added a UV lens to the lens barrel-to be honest, I bought a macro lens with a magnification of 2 times at this price.

I hope to adopt.
