Some more bokeh test pics, first from the Cosinon Tomioka 55mm f1.2.

Now for the Tair 11A.

And finally the Jupiter 37A.

Which topcor?
The f/1.4 bokeh seems to be the result of a PSF with a pronounced rim. The f/1.8 is much better but somehow looks streaky to me. I don't know of any lens that has a pronounced centre in the PSF.
the Topcor f/1.8 is much smoother. The Leica summicron makes me cringe. if you stopped all these lenses down a stop it would be more of a contest.

Bokeh aside, one big thing going for the Sigma for me personally is the sharpness at f/1.4.
IMO that's the only thing.

Interesting. I keep meaning to get into town to take some shots of those guys, but life has been interfering with photography for a few months.

Have you ever wondered if you might have a mild case of LBA

Nah, mild case of LBA no way known, severe perhaps, but when my wish list runs out I'll be cured.

Wow, Voe, that Summilux sure is a smoothie! Would make a great portrait lens, I reckon. No wonder it's your dream come true! It certainly shows up the Summicron 50/2 on page 1.

I think you've had a wonderful idea in starting this thread - I wonder if there are any other big-city-dwellers out there who'd like to start a similar thread for their own home town? (Assuming you don't mind if someone pinches your idea!)

Thanks. Of course I don't mind. The more the merrier

BTW, the 50mm Summicron is one of the worst lenses for bokeh, but it excells in everything else.

Yes, you often find that the sharper the lens, the worse the bokeh. As you're probably aware, it's mostly to do with sperical aberration and the amount of correction thereof.

For those who are interested, here's a link

Bokeh

and he refers to this

http://www.zeiss.com/C12567A8003B8B6F/EmbedTitelIntern/CLN_35_Bokeh_EN/$File/CLN35_Bokeh_en.pdf

which is very heavy going!

Generally I would agree with the above statement, but the are exclusions and one of them is the latest Leica Summilux M 50mm ASPH reffered by many to be the best 50mm lens in the world.

Yes, as I think you've just demonstrated with your last photo! You seem to have found the holy grail - a super-sharp lens with great bokeh, and I'm very jealous!https://www.pentaxforums.com/forums/images/smilies/lol.gif
