MMM 132mm STF, must be a new model, may only be a 3mm change, but it is a step towards getting a wide one :)

Come on Sony, you know you want to produce a 1.4/45 STF.

IMHO, judging from the photos, I would not call those CA, but "purple fringling" instead.

CA is when spectums of light do not converge to a single point. ie. there is a blue outline on one side, a green/red/yellow outline on another side of a subject. It mostly happens to the corners of the objects of a wide angle lens; or extreme magnification of a image from an average lens.

Purple fringling is more of a "digital" problem from bayer interpolation. The purple edge is found right next to an extreme bright source. The processing unit in camera is averaging an "infinity" with a darker color. It can be fixed manually with a desatuation brush in photoshop.

For a better explanation:
Chromatic Aberration (CA)
Bayer filter

i was dreaming of a 50/2 STF macro with at least 1:2 .. that would be the all round speciality lens.. you could do everything with it lol:) (100/2 STF macro would compliment nicely, this time 1:1)

I had this lens on my 7D last two days and it keeps amazing me with the performance; not only because of great OOF "drawing" but also because the lens is darn sharp even wide open with excellent color and contrast.
I know i did exaggerated a bit with the following images but, i guess this lens really deserves presentation trough some images.
However, the more i use the lens, the more i'm of the opinion that anyone thinking about this lens, should also consider installing focusing screen suited to manual focus. I do have a high percentage of slight OOF images which makes this lens not a perfect one for any critical shooting at least for me.













And a 100% form the camera

And a sample images taken with 135STF and Sony TC 2x converter. Sharpness isn't bad but PF is quite visible.

F4.5* 2xTC = F9.5 ?! According to exif :)

Kiklop,

Have you tried this STF with a filter, UV or Polar?

i thought for a second after reading this, and i think you may get serious vignetting with polarisers.. just a thought, if you have a polariser, would you mind trying?

you know, there is a gradient coated lens element in STF, the working principle (as far as i can ramove) is letting less light from outer edges of the lens, and getting a "center weighted" exposure.. if you use a PL, i think rays coming with narrow angles will be cancelled (is it what PL does??) so rays coming from center with narrow angles to expose outer edges will no longer be there??

most likely these are all nonsense.. anyway, i wanted to share:P

That was kind of my thinking that maybe a polar or UV filter would cut that down. Just a thought.

Seems very sharp, good for you that Santa is called Sony there :-)

Very nice images.

How much would be the price of this beauty?
