![]() ![]() ![]() On another note, I find the colors being produced by the 58mm f2 Helios to be much more vibrant and contrasty, really nice compared to my 50mm f1.2 ais Nikkor lens. When I shoot anything with a complex background that's more geometric, like shop lights, street lights or lit up signage, here is no spiral bokeh to be had, at least, not that I've managed to get yet.Īnyone else have an experience like this? Or are there some nice vintage lenses that produce wild spiral bokeh without so much effort? It seems the Biotar does it nicely but second-hand, those things are around one to two thousand $. The background really needs to be a bunch of leaves, trees, grass, or anything complex with a lot of light spots. ![]() What I've learned from this experiment is that achieving spiral or spinning bokeh is not as easy as I thought it would be. The aperture ring has no clicks, it just spins around which is fascinating, I guess it's useful for video. I picked up a very second-hand Helios 58mm f2 with an M42 adapter. Stopping lens down however can decrease swirling bokeh as coma also decreases when stopping the lens down). So lens that's otherwise got ring, donut or heavy onion bokeh can display nervous bokeh under right circumstances (however lens with swirly bokeh will have it regardless if there are any highlights in background or not. fuzzy, double-line shapes (one highlight appears as two).įrom what I remember swirly bokeh is caused by heavy coma combined with vignetting for more pronounced effect, nervous bokeh is caused by spherical aberrations often combined with a non-circular shape of aperture blades - also nervous bokeh tends to appear clearly when there are no highlights in the background - like on the sample I gave you above. Some being the Yashica ML 50mm F2 and the Canon FL 55mm F1.2 shown below. But other lens can produce swirly bokeh in certain situations. Nervous bokeh doesn't have any characteristic shape across whole frame, but individual blobs are not uniform or smooth and don't have any clear, characteristic shape they're more like. The most notable lens with swirly bokeh is the Russian Helios lens. Check out our swirly bokeh lens selection for the very best in unique or custom, handmade pieces from our camera lenses shops. The Rokkor is connected to the E-3 via an adapter. Swirly bokeh across the frame got a characteristic circular shape, stronger near the edges. It is just caused by physical vignetting of the rear element this causes oblique light bokeh patterns (closer to the edge) to have a cats eye effect: To get the swirly effect seen in the shots below, I used a Minolta Rokkor-X 50/1.4 with my Olympus E-3. What's the difference between "swirly" bokeh and "nervous" bokeh? ![]()
