While on the hunt for a real macro I came across this little gem, and Industar-61L/Z that I got for £12,50 shipping incl. It is a nice 52mm close focus lens, it says 30cm on the barrel but actually focus closer then that, about 28-29cm. It's surprisingly well built with a couple of oddities that one could expect from such a lens and the big x-factor have to be the printing on the left side of the barrel: Made in USSR.
Here is an example of how it does wide open at closest focus
It has a star shaped aperture from about 5.6-8 that I think qualify for the crazy bokeh thread

hi Lauge, heave fun with your Industar, it's a very nice lens worth more than it's reputation. Don't sleep near to it though, it's radioactive (Lanthanium) 
BTW the impression of focusing closer is caused by our tendency to calculate focus distance from subject to lens while in fact the correct measurement is from subject to film plane.

Nice lens and nice price!!
I paid much much more for mine, and it's one of the lenses I like more, with the CZJ Planar and Pancolar.

There is something about "radioactive" lenses here. Thorium is apparently the most radioactive element and lanthanum can apparently contain thorium in one of it's natural states. They only radiate about 0.9m away which probably means it isn't more radiation than the skin will blog most of it.
I wonder if 30-40 years of decaying (Takumar) will mean that such lenses has lost some of it's optical properties, like low chromatic aberration?

we should ask a physician, if radioactive properties and physical optical properties are related or independent from each other.
I have no idea.

Have anyone compared the bokeh rendering between Volna-9 and Industar-61L? I've read Tom Tiger's review of these two lenses, but I was wondering if anyone have a recent experience with them on a DSLR.
I noticed that my Volna-9 for example is not that sharp at infinity, and is not sharp until I reach f/4, but the bokeh is very interesting and it is far from crazy. Maybe more like a melting butter when used wide open and at close focus.
If you don't mind, may I ask you to post some more close focus photos and also more wide open photos.
Thanks.

Hallo,
I also heard that industar 61 is radioactive.
But not much: like environment (sun radiation).
To Orio: Any idea about bying radioactivity detector?

I checked it on a radio-activity - radiation is not present.

Sure, I'll see if I can take some more sample outside tomorrow. The crazy bokeh was in relation to the star shaped aperture that you only see in certain situations. So far it has shown nice and smooth bokeh but I need to use it some more to make a conclusion.
Camerapedia writes: "lanthanum is only 1/10,000th as radioactive as thorium" so I wouldn't expect Industar to be more radioactive than the dust behind the couch
My sister happens to have a master in physics so I have written her a mail about decay of thorium. I did a small test and my takumar showed more chromatic aberration than the industar but can not conclude if it has anything to do with the thorium.

As promised, here are a couple of quick samples.
Close focus wide open
At f/8'ish
Comparison of bokeh with S-M-C Takumar 1.4/50 (right)
Some random shot of a building just to show you something else
This is such a fun lens! The colors are not as saturated as the Takumar and bokeh not as smooth at smaller apertures but it's a great tool and I really liked what I have seen so far. As the colors are not that saturated and warm my guess is that it will be a good portrait lens so this will be it's next challenge.
Finally a simple test of the "crazy" bokeh (or fun bokeh) which must be the reason for it's name, Indu-star. (Sorry for the bad photo, this is the only one I got showing to clearly)

Volna-9 has the identical aperture shape, and Helios-40 a very similar one.
It seems it was popular then

Most of the radioactive lenses have the "hot" glass on the interior elements. A notable exception is the early collapsible Summicron. Lots of hot glass, including the front element. I put a filter over mine.
Thorium is an Alpha emitter for the most part. It is easily stopped. But in Physics class, we were told the danger was ingesting Alpha emitters as they would play havoc with your interior.
SO: has everybody seen the idiot that smashed his Hot Pentax 50/1.4 to cure the yellowing?
He should have sun-bleached it out. That works. |
