135mm f/2.8 (T4.5) STF Telephoto Lens
The King of the Bokeh!
This lens is the only reason to go with A-mount! The bokeh is extremely creamy and smooth. I guess they used 'smooth' in the name for a reason.
It does take some practice to get the best out of the lens and the bokeh is best when used at 2.8 (4.5 effect) but when all the ducks are in a row and you've nailed the shot, you could find yourself staring at the photo all day long :-)
I wouldn't have been able to use the lens without focus peaking function in a camera body. It helps tremendously and I don't know how people managed before without it.
You may find that the lens will challenge your old way of composition. For example, instead of trying to keep distracting objects and background out of your subject, now you can consider including them to see if they become pleasing bokeh to compliment your subject.
I am sure some other lenses, A-mount or not, can also produce pleasing bokeh under right conditions but based on many comparisons (you can search online), I still feel this lens comes on top.
This lens is sharp and its transition from sharpness to defocused area is very smooth.
If you are thinking about getting this lens, I'd say get it, learn how to it, and enjoy it.
