And eye watering price tag....

The other lenses mentioned sound interesting too, like a "fast" mirror APO tele. But calling it APO is a bit silly, as that is a characteristic of mirror lenses anyway.

Quite good blur albeit poor highlight rendition, I'd say. Low contrast at large aperture.

 

At this price they will not sell many though.

[Brightcolours]

Yes, I agree.. Very nice blur for 40mm, but cat's eye shapes due to a too narrow barrel, outlining of the bokeh discs, and coma is apparent. 

 

And yes, that price... I guess they aim for low numbers (as they are new to the game) which demands a high price.

They claim best sharpness for f/5.6 ... that is 5 (plus a bit) f-stops

down from max-aperture ... which is at least unusual for a prime.

Most of them get their best values 2 to 3 stops down.

 

Looking at the MTF-curves ... while things look ok-ish at f/5.6 ...

sharpness is next to nonexistant at f/0.85 ... well, probably

sharpness is not the reason why one would buy such a lens.

 

I do find some of the sample images nice ... but at the price they ask

for it, I easily get a used 5D plus a 50L which allows the same

type of images (with the plus of AF and aperture controlled by the

camera). So, likely this 40/0.85 will remain a gimmick for those who

already have everything else.

 

Just my thoughts ... Rainer

Especially considering the upcoming Leica 42.5mm f/1.2 ...

Well, the 50mm f1.2 L USM does not have that smooth a bokeh. But for the rest it is quite an awesome lens.

 

The 50mm f1.2 L's MTF wide open are (naturally, I would say) not splendid either:



Compare that to these:

The price of the CINE version of the SLR Magic 50mm f/0.95 is not that far removed from this... and it's a full frame lens. If someone can fork out $2K for a left field lens like this, $3K is probably not totally out of his/her reach. And the SLR Magic is now proven as a quality lens. Just my $.02

[Klaus]

The SLRMagic didn't work so well on the NEX 7 ...

The SLRMagic didn't work so well on the NEX 7 ...

But probably quite a bit better on a NEX-5r?

[Klaus]

Possibly. As mentioned I gave up on the NEX6. Not because of the NEX6 but because I just don't have the time.

However, given the average production lifespan of a Sony NEX, those 16mp sensors will be history very soon anyway.
