Puerto Vallarta 2010 by John Carter, on FlickrThat is very nice I have to say. Very soft bokeh - I like it. I have one with a rather poorly handled front element (missing quite a bit of coating) that I shoot almost always stopped down. Even then I find its very low contrast though this may be due to the above problem. Did you find it necessary to work the images tone and contrast over in post processing? That's what I fancy I would need to do to get the nice contrast you have. Even so I must try mine out open - I have been put off by its problems but should be more brave.
Hi Peter
That image actually is uploaded via Mobile from a Sony a7 in camera jpeg .
The current copy I own of the canon 50mm f1.2 is I believe quite a lucky catch.
It's made from 2 lenses. One that had a very poor front element and another with a rear group that was foggy between elements. (I gave away the spare rings/helicoid and bits here on rff so others have some bits from these two lenses also).
Now I have this lens that has surprisingly strong even at wide open.
Here are 2 more image(s). This one with the cropped sensor Fuji XE1 in provia film pre-set.
I like my f4.0 200mm Super-Takumar, this shot only shows a little of the bokeh.

I also like the 50mm Super-Takumar f1.4 and the Pentax F 50mm f1.7. This shot is the f1.7. Both have smooth bokeh.

Peter, I guess you've got this one too? Summicron 5cm f/2 LTM collapsible @f2 on APX100 in Rodinal 1+50

I am interested in knowing more about the Trioplan(s) - they seem to go for a surprising amount of money online given they seem to be all made with what looks like a fairly soft alloy body. (Those I may be wrong in that). But I was aware that they are well regarded - your lens comes up a lot in conversation when long lenses are discussed.
Is this the one?

Looks good to me - I love the vintage "look".
BTW I have recently been alerted to the joys of Exakta mount lenses - for obvious reasons they are cheaper than m42 versions of the same lens (least that is my impression) but m4/3 and NEX mount adapters are now readily and cheaply available so the Exakta camera mount is no longer really a deficit that it once was (shhhh dont tell anyone 😉). I have bought a couple recently - a no name 35mm pre set lens that came out of a security camera of all things but never the less it is pretty sharp and renders quite well. A $5 purchase. And a 105mm Schneider Kreusnach Xenar f3.5. They are recent acquisitions so I have not had a chance to give them a solid test run for bokeh yet.
