[鏡頭介紹] Minolta 135mm F2.8 [T4.5] STF

siumaibb

有 LYK 話想影有 bokeh 效果既相，我就諗起呢個 lens。需然 Konica Minolta 係業餘野，但係都偶有佳作，就好似呢個 135mm STF (Smooth Transmission Focus) 鏡咁，係一個構造特別，為Bokeh而設既鏡頭。

呢個十年前出產(Sony rebrand 後再出)既鏡頭，有幾個特別之處，其中一個就係有兩組圓邊既光圈。


另外就係獨有既 Apodization element

小弟無緣(即係無錢)試下呢個鏡頭，所以review都係睇 link 啦：

順帶一提，Nikon都有類似既 DC (Defocusing Control) lens，不過，當然係無 Minolta 呢個 apodization filter 做得咁徹底啦。

Can I ask why it's better than the Nikon Defocusing Control?  I wish I can have both lens to play around too

Practically, this is a manual focus lens with effective aperture at f4.5.  I even had a hard time focusing a manual 85mm f1.4.... getting old... ouch!

you have a Minolta too?

quoted from www.the135stf.net

"The closest immitation is offered through Nikon with their 135/2.0 AF DC (Defocusing Control) Nikkor lens, designed with similar purposes. The Defocusing Control is an excellent lens, that offers Nikon users the ability to make out-of-focus areas appear softer by strategically introducing spherical aberration to just the defocused areas (in-focus areas are not affected). The Nikon DC lens has Autofocus, but cannot meet the supreme standard of bokeh of the STF lens... the DC lens shifts lenses around to over-correct or under-correct for spherical aberrations, to optimise the unsharp areas in either the foreground or background, but not both. Only the apodization filter in the STF lens optimizes both foreground and background unsharp areas."

yeah, I tried my friend's 85 1.4, at wide open 1.4, it is not easy to focus.

I grew up in a Minolta family and my dad switched to Canon after digital age.

Minolta's always innovative...however, after they invented something other makes will take it and make it cheaper and better...sigh

The bokeh looks really good bor.
