Very interesting article about the Bokeh Kings.

Thanks for the link. As an unrepentant bokeh whore, I appreciate it. The author, with this article which is half argument ender, and half argument starter, has saved me a lot of work-work I was never going to do.

A good read. Thanks for sharing.

I'm not so much in the technical details of photography but I found interesting to read this article, thanks for the link.

"World War", "M9 focus shift", do you really take this article seriously?
Noctilux, M240...deep valet people crap talk with 50mm M label.
To me Canadian 35 Cron v4 is the King of Bokeh 🙂

Wow, check out the Summilux ASPH at f2.8 !

Thanks for sharing, Erik.

do you really take this article seriously?

Yes, actually I do. We now have the opportunity to compare the effects of lenses we hear about often but can never compare them ourselves. When you are interested in the effects of these very fast lenses and their differences this comparison is really very informative.

Well, I was only reading, pictures were not opening. 😀

Interesting indeed!

I read a comment on Instagram recently mentioning that the saw-toothed pattern aperture blades (like the Summilux ASPH at f2.8) are used to reduce focus shift. First time for me to hear that. Is it true? Does anyone else know anything about this?

Propogating this internet myth will do no more for s/h prices!
I really liked my v4 but disliked it's build quality after a while. I had 3 so it wasn't just my copy.
Interestingly I did a poll a few years back between my Ultron, a v4 and a pre asph summilux. The Ultron was the clear winner until I revealed the data and then guess what? the v4 surged ahead.
Apart from size and min focus I still believe the Ultron to be the v4's equal and I shot them both quite a lot back then.

Is it true?

I don't know anything about this effect - maybe it is true - but I quite dislike it from an aesthetic point of view.

The Ultron-LTM is indeed sharper.

I think it's just a matter of the shape of the aperture. The only other lens I know where the "bokeh teeth" are that pronounced is the Canon 50/1.4 LTM (see http://www.rangefinderforum.com/forums/showthread.php?t=155193).

As a side note, some of the softness that can be seen in the wide open shots is due to shift. When you account for the cosine effect (focus and recompose), some lenses might be "sharper". I know my Nokton 1.1 behaves like this.

Thanks Erik - very interesting and useful

Bokeh (the look of the OOF areas--- tapering (featuring) of the sharp to OOF, rendering of the OOF edges, how the OOF areas are rendered IE Swirlly, Creamy soft)

Are determined by the manufacturer, and the correction or lack of full correction of the optics Spherical Aberrations and other optical aberrations for the most part.

And, all bokeh is good.... but, our seperate likes and dislikes determines what [kind] of Bokeh we prefer in our photography.

Bokeh is of course subjective, and involves personal preference....

Interesting article with the many comparisons presented.

Thanks for the article, had a chance to give it a brief look over and bookmarked it to explore in full later on. Enjoy the different bokeh offered with different lens.

Aesthetically all looks the same to me. :angel:

Seriously -- I was actually surprised how little it mattered.

A minutiae-fest... 😉 They are all nice.

I see differences, but it is hard to say wich I like best.

It's all good but it's all different. Just like us.
