One of the reasons to use old lenses is the bokeh performance. Maybe this forum has the best reputation in the net of bokeh competence.

This morning I have made a shot out with 100mm lenses. All lenses set at f4.


Beside the personal taste, if you go for the bokeh rules. Wich lens has the best bokeh?

I will tell you later, wich lens is behind the number.

Thanks you.

Ingo

It's not easy to talk about best bokeh separating from the images as a whole.

If I only have to take bokeh into consideration, #2 and #5 seem the more pleasing to me.

However if I look at the subject, the volume and the texture of the statue are better rendered in #1 and #3

As a compromise solution I would probably choose #1 for overall image (considering both bokeh and texture/volume)

I completely agree to Orio. Although the bokeh of number 4 on first sight seems to be creamy, it still shows an unpleasant effect.
Number 2 and 5 are the favs. (No.3 "suffers" a little from the hexagonal shape.)

I agree that #2, then #5, have the least annoying backgrounds.

#2 and #5 have the 'softest' bokeh of the shots shown. #1 has a 'harsh' or 'sharp' edge to it. #3 shows the hexagon shape of the aperture and as I stated before, I am not a fan of 'shaped bokeh'. #4 also has a harsh edge to the bokeh, just not as bad as #1.

If I had to choose, I would select #1. It is the closet to what I personally like to see (usually).

#5 is my favourite bokeh there Wink
It seems that there's a slight difference in lighting between the images, so it's a bit hard to compare other things. What lenses did you use?

Ok, here is the lens list. The lighting conditions are the same.

#1 Voigtländer Skopar 4,5/10,5cm (classic Tessar design, 1927)

#2 Voigtländer Heliar 3,5/10,5cm (1927)

#3 Meyer Orestor 2,8/100

#4 Meyer Trioplan 2,8/100 V

#5 Sigma 50-150 f2,8 EX APO (yes, modern AF lens)


I have also shot with 135mm lenses.


#6 Carl Zeiss Jena Sonnar 4/135



#7 Sigma 50-150 @135mm



#8 Soligor 2,5/135

The ole sonnar spanks everyone else both for bokeh than from tridimensionality but I guess these are not news Laughing

I agree. In the first set #2 is my favorite overall.

Nice presentation. Thankyou

I have chosen blind the Skopar/Tessar image amongst 5.
This must mean something Wink

This also shows that a modern AF lens does not necessarily have to be a bad lens. Wink

Yep if you have the luck to find a Sigma that doesn't crumble to pieces after some moths and have focus alignment problems. Not to talk about that the lens in question would cost you about 10 sonnars.

Congratulations!

By the Meyer I see the 6 blades in the bukeh - this is a very good test - thank you very much

regards Peter

In the first group, #2 and #5 for me. I'm slightly disappointed in #4, but it seems characteristic of the Trioplan, which has other qualities.
