Hi everybody, today I did a very simple test, a friend was clamming that the best bokeh is the one from the Nikon 135 f2 and the sharpest lens should be the Nikon 70-200. I was not agreed I have the STF but with the A900 was very hard to get sharp pictures, now that I have the A99 is so easy with focus peaking that i told him to conduct a very simple and quick test.
Results are awesome, he brought his D800 and the 135f2 and 70-200f2.8, I use my A99 and the STF, here are the results, be you the judge.
All photos where taken in raw without any sharpening in pp

Gorgeous bokeh. I very much like the STF's treatment of the green overhanging limb in the background.

I'm surprised he didn't get better bokeh out of the 135/2. Did he make use of the defocus control?

Winning a bokeh fight with an apodisation lens is like shooting fish in a barrel.

As for the 70-200, to my eyes the current Nikon is in third place after both the Sony and the Canon IS II.

Hi Carl, the test was not only for bokeh comparison, we also test the Sharpness of all lenses.
All photos were taken using tripod.
I dont really know how to use the defocus control in the Nikon lens, but I guess hi did it right

Next week we will run some ISO tests using and D800, 5D Mark III and the A99.

The bokeh of the Nikon lenses looks somehow disturbing in comparison to the 135STF.

Its also a good comparison to proof that bokeh matters. Its an integral part of the image.

In the posted picture size, sharpness of the lens isnt important - bokeh is.

Wow clinical bokeh. As I've thought before regarding the STF's pictures, I'm not totally sure I like it. I wonder how the Nikon 135 f/2 bokeh would have looked at f/2, though. Whatever it would have looked like though, right here: if the others' bokeh is ADHD in comparison then the STF's was just pronounced dead?

In terms of sharpness and dolly's face, the STF and 70-200 appear a bit even, but the 135 f/2 seems a little bit front focused? Looking at the face and then the stitches on the feet.

Goes to show how easy the A99 makes manual focusing, perhaps = ) (Or perhap's it's the f/4,5 aperture? I haven't used the lens and am not sure exactly how it works)

Grat job Arturo! I always wondered if the Sony STF was better than the older Minolta model and so far I like what I see.
The Nikon looks to be a sharper lens but the bokeh is nowhere near the STF.

The 135 DC lens of Nikkor doesn't stand a chance against the STF not in terms of affecting the bokeh anyway. The Defocus which plays with SA is very subtle and comes with the penalty of a lens that will be very hard to nail focus with wide open (AF).

However the STF while producing "clean" bokeh can also be to much, to the point that it looks like a photoshop filter.

The STF does of course comes with it's own penalty of being a slow lens and lacking when it comes to subject isolation due to DOF.

Neither have I, but as far as I know, the aperture is 2.8 but the amount of light transmitted is 4.5 (can be 4.5-6.7 at 2.8 aperture). So depth of field is like 2.8, brightness is like 4.5.

You are right Jenik, the aperture is 2.8 in terms of DOF, but 4.5 in terms of brightness.
The STF lens is so sharp and its bokeh is so perfect that looks a little bit unreal. My friend was so dissapointed with the results of the Nikon glasses that he's thinking on switching LOL.
In terms os sharpness STF and 70-200 are very close, maybe a little more microcontrast with the 70-200 at 100% but in real World they are just the same.
I have read the results of DXO and they said that in terms of dynamic range D800 is better, but what I saw was the oposite, A99 had a better dynamic range, shots were taken with a 10 minutes gap and that could be the reason but histograms shows that A99 had a better dynamic range.
Of course these are not 100% controlled tests, just a couple of friends having fun with real World tests

The STF smashes the Nikkors handling of specular highlight on car in background.

Interesting the STF greens on doll and ground match the Nikkor zoom better. But the greens of the branches better match the Nikkor DC.

This test is inspiring... Can't wait to call my CaNikon buddies and see if they want to play dolls with me.

Those pics have blown me away! Was offered an STF recently but a fellow forum member but decided I'd wait until I get an A99. Seeing these pics though, that day may be sooner than I thought!

Would love to see the 135CZ 1.8 thrown into the mix too though...

Well I promise I'll do the test again and we will include the 135 Zeiss too. We are still looking for a friend with a Canon and the 135 f2 to have the complete set
