Swirly bokeh on 4.6k sensor: how ?

PostThu Aug 18, 2016 2:14 pm

Hi all !

I'm looking for a vintage lens that can produce a noticeable swirly bokeh on the 4.6k sensor (almost aps-c then).

Every lens I'm finding are for Full Frame. Any idea ?

thx :)

Have you looked at Petzval lenses? Not vintage, but based on a vintage design. I've never used one in a project but have played around with them at camera stores. They are full frame but will work fine on an APS-C size sensor.

Yes, I checked but indeed, they are full frame, so the swirl effect will be far less noticeable :/

You could try a Lica Nocilux, they have a very unique smooth swirly Bokeh, but they anin't cheap!

Yea, I know. That is why I went with the Panny/Lieca 42.5 Noct., got a good deal on a slightly used one. But this is a MFT lens, so will not work with the Ursa Mini. But then, I have the Micro cameras...

I think Jupiter 85mm/f2 has that look... I am waiting on mine to arrive so when it does I can let you know for sure.

Have you played with LensBaby?

http://lensbaby.com

You'd have some sort of optical control over how the bokeh works. Or a facsimile of it.

Obviously the real issue is that there really aren't normal lenses in the super-35 size that produce the super shallow depth of field of a fast medium tele lens on a full frame sensor. Have you tried a Nikkor 55 1.2 AIS? They're reasonably priced.

If it produces a swirly bokeh, I'm interested !

I'm aware of the lensbaby, I just forgot about it, thx ! But I don't think it will be an option for me, I forgot to mention that I plan to use an anamorphic adapter with the lens (SLR Magic Anamorphot/Isco 2x).

I'll check the Nikkor as well, thank you !

The vintage Russian Industar-50/3.5 M39 have serious swirly bokeh. They are a collapsible design that will adapt easily to EF. You can pick them up for around US$50 or less.

Helios 40-1 or 40-2 are perfect for swirly bokeh. I miss the one that I had awhile back...

Don't. The collapsible part could damage the sensor. They are for range meter cameras where is no mirror. Choose the same Industar 50 non-collapsible, if you insist on this model.

The Helios 40-2 85mm f1.5 has an awesome bokeh.

The sensor is way behind the lens mount, the moving part would never reach it, it's too far behind. Same for the Helios, the back is moving but not that much.

btw, I received the two lenses, still waiting for my adapters :) Some IR cuts and a Variable ND as well.

But the Industar is really small, with a filter thread of only 33mm (built in 1965, it's bigger after the 70's), and it's kinda hard to find such a small ring adapter :o
