|comment:||What a lens ! Was dreaming of owning one from day one I`ve heard about it.|
I would consider it a perfect portrait lens. Obvious downside is lack of autofocus; this may be remedied to some extent by using a camera with focus peaking; nonetheless in low contrast areas (which a face easily is) peaking doesn`t "peak" = the focus magnification is necessary, otherwise it is hit / miss game since the DOF is tiny at F2.8 (T4.5). Therefore it requires some time to arrange a photo (longer than for autofocus lenses) - my Minolta 135mm F2.8 is more suitable for quicker actions.
A bit longer on APS-C, but still pretty usable, giving results (especially in the out of focus areas) as no other lens can deliver.
The lens is plenty sharp, well appropriate for landscape photographers too.
On the negative side - I was surprised how much purple fringing I get in high contrast areas - while it can be corrected in post processing, it`s a small annoyance for me.
In comparison to other portrait lenses I own / owned - in sharpness it equals to 100 F2 and Zeiss F1.4 and it`s sharper than Minolta 135mm F2.8. But non of them can match it in the bokeh field - the winner is clear here!
This lens is bringing real joy to my photo hobby !
