No bokeh problem at f/1.4. It becomes to be sharper as slower apertures. I would try again at f/2.8 with light sources in the frame.

 

Actually I have printed this at A3+ size and i'm very pleased with the sharpness. The focus point was the side arm of the spectacles. I dont think trying again is an option. If I had wanted to shoot at f2.8 I could have used my summicron.

iMHO, this lens doesn't have 'bokeh'

 

It's out of focus is so smooth that at closer distances it perfect out of focus rendering makes the perspective look more like an 85mm lens. If it does have 'bokeh' its bloody boring....which is why I use it. Background out of focus is smooth and undistorted, perfect for professional work.

 

For more personal work, I'd prefer the pre-asph any day of the week for it's character.

Here is a 50mm Summilux ASPH shot that consists nearly exclusively of boke. 1:2 at 1/30th and ISO 1000. The focus is on the bow of the second fiddler from the left.

 

The picture was taken yesterday, Saturday, during the National Folk Music Meet in Stockholm. The old timber Seglora church is quite dark inside. Outside the south window in the picture, the sun is blazing. The contrast is extreme – it is like aiming the lens directly into a bank of halogen lights. One important part of boke, to my mind, is the ability to handle such an extreme situation without internal reflections and with no more flare than what gives the shot a bit of atmosphere. No other high speed lens I have experience of could have done this, with the (possible) exception of the 35mm Summilux ASPH FLE.

While I agree with you Lars, the Summilux ASPH isn't the best 50 when it comes to shooting against light. Here is an example shooting into the sun. Shot 'without' a filter wide open with the sun placed at top of the frame. Stopped down may have improved it's resistance to the reflections.

all of 'em lovely of course.

 

Are you all aware that you are asking, and getting, performance that is so far beyond the Tessar T* standard of not many years ago? You demand the ultimate smoothness and lack of flare straight into the light (so do I, now I've become used to the latest computations), whereas our fathers would have tut-tutted at pushing the kit this far.

 

We are blessed with the best lenses now, that the World has ever seen, and because of economics and software fixes, probably ever will see.

Well, you like internal reflections all over the picture. I like a minimal amount of flare, and no reflections. De gustibus non est disputandum.

 

But my argument was not about taste, but of technical quality – about what I like to call subject fidelity. And these two are different matters. The inability to distinguish between them is common, but it makes just about any discussion about optics meaningless.

 

And you did not state a.f.a.i.c.s. what lens you took the picture with. Though I think I can guess ...

I never said I 'liked' internal reflections Lars.I also wasn't talking about taste, but following on from your point about technical quality....you're putting words into my mouth mate. There's no inability to distinguish anything...just you seem to be misunderstanding.

 

I stated what lens it was very clearly.
