I tried to find such topic, I couldn't find it. If it already exists let me know, I will remove it.
Today I received Auto Yashinon-DX 1.4/50
Here we go:

A collection of bokeh then...
Here's one from a zuiko 55/1.2, a lens I use a lot but usualy for portraits. This duck was under a picnic table yesterday - quite dark so I used the pop up flash as fill in but the speed was too slow so a bit of blur is evident. The aperture was still on 1.2.
This is not typical from this lens, I suppose it's something to do with the grass and it's closeness to the duck. Normally the backgrounds are a little further away.

front and back out of focus areas,
Super Takumar 50mm f1.4:




S.M.C. Macro Takumar 50mm f4:




( I sometimes worry about this big size, I hope it is OK. I host my photos at flickr in original size and there I get options to link various sizes, this one here is 'large' and 'medium' I feel is too small )

Here are some of my Radionar test shots. In the first one, the front cell was set at 1m and the focus with a variable close-up ring to about 3m. The result was slightly soft focus and a very Gaussian bokeh, note the highlights at the cathedral (NB. the sky was rather cloudy and the sunlight very weak.)



Setting the front cell to 2m will decrease the softness and make the bokeh somewhat less Gaussian. The first, very slight artifacts appear:



A similar test pair with a different subject. Note the farthest ropes of the rigging.





Finally two shots where the subject is somewhat further away. The result is rather picturesque:





The dual focusing system has a lot of potential for softness and bokeh control, but for the full range of setup combinations I have to carry two interchangeable main focusing devices, both the adjustable close-up ring and a bellows. The closest focusing distance with the ring is rather long when the front cell is set at infinity, which rather restricts the adjustment range for nearby subjects. With the bellows, infinity focus can only be achieved when the front cell is set at infinity, which limits the soft focus adjustment capability for faraway subjects (the bokeh doesn't matter at infinity as there is no background.)

Kuuan that Macro Takumar shot is totally awesome, I just spent 5 minutes just looking at it.

The bokeh from the duck shot above made me wonder about the zuiko 55/1.2 so I tried a few flower shots this afternoon.









All wide open for maximum effect. Nothing as weird as the duck though.

Toenails our cat died last year, I remembered this photo because of the great Zuiko pics above... This is with the 85mm f/2.

These are all great examples of boke. Some I like some I dont - boke I find is a very subjective issue. Persoanlly I prefer the "creamier" variety.

the dual focusing system sounds very interesting ( never have had haerd of it before..)
I try to understand it, difficult with my limited experience.
Could you be so kind and offer a photos of how your set up looks like?

I like all your samples, best even the later ones, e.g

wow, thank's very much Nesster.

I very much like your sample taken with the Yashinon:



Yashinon..once again
All the samples of Yashinons I have seen are quite outstanding, must get one down the road: anybody knows which Yashinons are regarded most highly?

best regards,
Andreas

Andreas, congrats again on the Takumar 50/1.4! Really like the foreground/
background bokeh in that shot! The term "bokeh" is Japanese, how appropriate.

Some great shots from all of you! Thanks for sharing!

These shots look amazing and very different from modern, conventional lenses. I'd like to see your setup, too. Wonder if it's possible to assemble one.

Andreas,
My other Yashinon is a 135/2.8. It isn't the best 135 out there.

While I've not managed as extensive experience as Veijo, I do have an old lens hooked to the far end of a bellows.

What he's talking about - most of the folding cameras had front cell focusing. That is, you turned the front element forwards to focus closer. Now, when you mount this lens on a bellows, you can move the bellows forward to focus closer, and/or you can turn the front cell.

Here is the setup used for the above photos:



I have glued the Radionar (still mounted in the original shutter set at T) to a short M42 macro extension tube so that it is easy to change it between an M42 bellows and the Asahi Pentax Adjustable Close-Up Ring shown in the photo. The front cell of the lens is mostly used to adjust the image quality and the adjustable close-up ring to focus, which method allows any setting between a "normal" and a soft focus/bokeh. Here is an example pair of photos:





and another couple of shots just to show the leeway:





When extreme close-ups aren't desired or the highest possible contrast or resolution, this is one of my favorite lens systems, a most flexible one as you can see.

looks great, just as do your photos, very interesting set up indeed!

could you elucidate further on your settings, e.g. comparing the first to the second photo of in your last post?

Viejo, tell me, do you know for how much this Pentax ajustable Close-up Ring usually sells for?
I had just had 'found' one in a shop here, it was the first time I ever saw such a thing, and that just a few hours before I saw your post. A sign? but it sells for over 100 USD!

thank's again for your explanation of your set up,

best regards,
Andreas

Well, I wouldn't know the usual price. I got this one from eBay for GBP 15 + postage, which was cheap, I guess.

thank's Viejo, and sorry I had edited my post asking also for further clarification on how you set your lens/focus just when you must have added your reply

thank's,

I like the bokeh very much. But i like more the expression of toenails. The subjet matter is the question of each shot, no? While the bokeh don't obstruct the principal idea of the pícture, is a taste quid.

Fatntastic shots! I like the bit low contrast - not as low as natural way - not too saturated colors. The three elements play the game so well!!!!

In the first one the front cell was set at 1m, i.e. grossly mismatched relative to the focus distance. In the second one it was set at 3m or so, which is a good enough general purpose setting.
