Carl Zeiss Jena Sonnar MC 135mm f/3.5, one of the great lenses produces by Zeiss corporation which is famous with its lens's fabulous quality, established by Carl Zeiss himself. At a glance, we can see that this lens is so elegant with its black colored barrel which is so beautiful.. We can see the aperture and focusing ring so clearly . With its 49mm filter ring, the front elemen can be determined that this lens is a first class lens.
Based on my personal test of the lens's sweet spot, I will explain the lens's performance in order to give you clear perception about how this lens is performing. But first, I need to tell you that sharpness and color perception is very subjective. My conclusion here is merely my own opinion. I will let you all decide what is your own perception. This test was conducted using manfrotto carbon tripod, Sony Alpha 700, ISO200, AWB. The test was conducted outdoor on 9:30AM,at f/3.5, f/5.6, f/8, f/11, f/16 dan f/22, without any digital modification except resize and crop.
f/3.5 wide open
As you can see that the lens's sharpness is still in its best condition especially for a vintage old lens. A very good detail is still visible even when it is widely opened.
The "Bokeh" swirls beautifully. This is why enormous number of people have fallen in love with this Zeiss's lens.
I'm confident to recommend this lens for those who is still searching for a very good quality manual lens.
