Cheap lens with crazy bokeh?

    Hi!

    I have seen some photos out there which are technically horrible, low sharpness etc, but interesting with crazy, swirly, out of this world bokeh, like this:

    http://www.flickr.com/photos/67901606@N05/8969878280/in/pool-legacyglass

    One that one it says: Soviet Cyclop 85mm 1:1.5, from a night vision device (!)

    That seems kinda rare and a bit weird, and hardly technically sound in any way. But the out of focus rendering is crazy fun!

    Can someone please point me in the right direction of something in this ballpark, but cheap, readily available and easily adaptable? If those things can coexist, that is.

    Thanks!

    If you look for a Fujian 25mm and a Fujian 35mm on ebay they are relative cheap (about $30 each) and both have that swirly bokeh characteristic. You can look up other c mount lenses as well, since a number of them have a characteristic swirly bokeh. For instance, I have a Kominar 25mm f1.8 c mount lens that when in close focus creates a swirly bokeh.

    Helios 44-2 or 44-3 (~$60 for a perfect copy). Helios 40-2 (more $ but well-loved). The Cyclop that you mentioned. All have the Zeiss-swirl.

    It looks like the doughnut circles from a 500mm mirror lens.

    That's generally associated with lenses of the original Zeiss Biotar formula. So the original Biotars will do that, as will the Helios 44 lenses ( as mentioned ) because they are basically Soviet made Biotars. Most normal primes are variations of the Biotar formula. As time went on and the formula was tweaked they stopped exhibiting that character. I'd assume c-mount lenses tend to do it because they use simpler optical formulas.

    Of the lenses available, I'd go for a Helios 44-2 or 44-3. They're a 58mm f/2 lens which doesn't vignette like most c-mount lenses will.

    any of the cheap c mount lenses will give you that swirl
    i just read an article somewhere about lomo coming out with some huge brass beast of a lens they are making a modern version of specifically to do that swirl... and i thought "my $15 cmount lens gives me those exact photos...."

    I checked out some fujians, dirt cheap and often including adapter. But I thought they seemed very small and was wondering about vignetting. The photos on flickr didn't show any...

    How much are we talking about? Massive cropping necessary to remove it, or just enough to add to the general weirdness?

    vignette on the c-mount lenses will vary. Typically 25mm will have some, anything wider will have way more, longer than 25mm will have less. But yes, what you're looking for you can probably find in the fujian lenses, or other old soviet lenses.

    This was taken with my Fujian 25mm f1.4.. Swirly bokeh all over the place...

    Wow, these Fujian lenses are interesting! From looking at the sample archives it appears as if the 25/1.4 is the real swirl monster and the 35/1.7 is not as swirly?

    I think I might buy one to try. They're only like $30 including adapter. It'd be something fun, different, and the most creamy/swirly bokeh as possible. One thought, however, is that the 35 would have better bokeh because it's a longer focal length, even though it's only a 1.7. But looking at the samples I think the 25 is more swirly and cool.

    Also, why are the grips on the silver different? I thought I'd try the silver color but I don't like the cheap-looking grips on it :( I did see a stainless adapter which looks cooler than the black :)

    Here are some I took with a Fujian 35. It has a bad tendency to flare or give a white spot in the center when wide open outdoors. But that effect does have some appeal.

    With the same image size the f/1.4 will have slightly shallower depth of field. Image size and f stop determine depth of field. The difference between F/1.4 and f/1.7 is pretty small. I'd go for the one with less vignetting. As to which would have better bokeh, I have no idea.
