The Sony 135mm f/2.8 STF lens[/shoplink] (image Photozone).
One source told us the next Sony 85mm f/1.4 FE lens will be trimmed for extreme bokeh. So let me speculate a bit: It may be possible that this will be the first Sony STF lens after the [shoplink 38557 ebay]135mm f/2.8 STF (here on eBay)[/shoplink].
Photozone explains well why this 135mm lens is so special:
The lens has a so-called apodisation optics using one APD element. APD elements resemble neutral density filters which become thicker the more you move towards the perimeter thus reducing the amount of light passing through. Out-of-focus circles are therefore (comparatively) defined in the center but are gradually loosing light towards the edges thus producing a very silky bokeh (out-of-focus blur) – the primary sense of existence of this lens.
as a result
The [shoplink 38557 ebay]Sony 135mm f/2.8 [T/4.5] STF[/shoplink] is the ultimate cream machine. Regarding the quality of its bokeh (out-of-focus blur) it outclasses all other lenses tested to date so if this is a #1 priority for you just bow to the inevitable and go for it to enjoy images as smooth as silk. That said it doesn’t stop here. The lens is extremely sharp even at max. aperture and neither vignetting, distortion nor lateral CAs are something to worry about in field conditions.
Sounds great…and expensive(!) if Sony will really make such a lens…
