Meet the old boy: Sony SAL135F18Z Carl Zeiss Sonnar T* 135mm f/1.8 ZA

ISO 100_1-5000 sec at f - 1.8

Wide open f/1.8

Released in 2006, this was one of the most outstanding lens in the A-mount family. However the development of A-mount lens together with the A-mount camera was apparently stopped until the latest A99 mark ii published in late 2016.

For E-mount user, we can still enjoy those high quality A-mount lens using the native adapter LA-EA4. The adapter works perfectly however the built-in focusing system is a bit slow; it is still usable for portraiture and still.


You can see the shadow depth of field when wide open (f/1.8).

Although this lens a bit old when compared to the latest 135mm lens produced by Sigma and Batis, it is still sharp and the color it rendered is natural.

I perceive her resistance of flare is above standard, considering an old lens.

Portraiture is the specialty for 135mm lens. With large aperture, f/1.8, the background blows away with creamy bokeh behind. This lens inherit the feature of Zeiss family, sharp and strong outline with warm color rendering.

In light of optical performance it may not be able to beat the latest model, e.g. Zeiss Batis 135mm f2.8 however her beauty is unique. When you use it, you will be impressed by the image it rendered.  When you hold it in your hand, you can feel it is a seriously built product with no compromise.

A-mount seems to have fulfilled her mission to introducing Sony into the camera industry. The company needs a new product line, the e-mount, which can create a new cycle of profit making. As a result, A-mount camera and lens are fading out but that’s exactly a great opportunity for user/ amateur like me to collect those high quality lens in a bargain price. I can’t find another Zeiss lens with AF at f1.8 selling in such attractive price.

See the picture and feel the emotion, not sharpness
