I have one that has been sitting around in my dry box. Not selling. Keeping it.
On a APS-C camera, it is a nice lens for candid shots.
On FF camera, it is neither here nor there range; i.e. too short for outdoor and too long for indoors. Someone said it is great lens that produce great images to use for indoor studio with FF body if you have the space. Much better than 85mm f/1.4.
The funny thing, I use the 85mm more for indoor and outdoor portraiture than 135mm on my A700. Maybe I should buy FF body soon....;p
