View warranty terms and conditionsThe Sony 135mm f/2.8 [T4.5] STF is a fixed telephoto lens designed for the Sony A mount, released in 2006. Its most outstanding feature is the Smooth Trans Focus (STF) technology, which uses apodization optics to soften the edges of out-of-focus areas, achieving exceptionally smooth and creamy bokeh, ideal for portraits and nature photography.
With a maximum aperture of f/2.8 (which functions as T4.5 due to the apodization elements), this lens allows capturing images with very shallow depth of field, highlighting the sharp subject against blurred backgrounds. Its focus is manual, with a minimum focusing distance of 0.87 meters, and it features a 10-blade diaphragm for pleasant circular blur. This second-hand unit has been inspected and comes with a Camera Market warranty of 6, 12, or 24 months, offering a unique opportunity to acquire a specialized lens at a more accessible price.

What is STF technology and what advantages does it offer?
STF (Smooth Trans Focus) technology uses apodization elements that soften the edges of out-of-focus areas, achieving much smoother and more natural bokeh than a conventional lens. This is especially useful in portraits and detail photography, where a highly blurred background that does not distract from the subject is desired.
Does this lens have autofocus?
No, the Sony 135mm f/2.8 STF is a manual focus lens. This allows precise control over the focus point, especially when working with very wide apertures and shallow depth of field. It is ideal for photographers who prefer manual control or who work in static situations.
Is it compatible with my Sony camera?
This lens uses the Sony A mount, so it is compatible with Sony DSLR cameras that use this mount, such as the Alpha series (e.g., A100, A700, A850, A900, etc.). If you have an E-mount camera, you will need an adapter, but keep in mind that manual focus will still be necessary.
What does the Camera Market warranty include?
This second-hand lens has been inspected by our technicians and works correctly. It includes a 6, 12, or 24-month warranty (depending on the chosen option) that covers any functional defects. If you have any issues, you can contact our customer service to arrange repair or replacement.
