The Great Bokeh Controversy: Snare or Delusion?

Bokeh is a Japanese word that refers to the subjective visual impression of the out of focus areas of an image. Just because bokeh isn't objectively measurable doesn't mean it's BS, but there's certainly been a lot of BS written about it. What imaging characteristics contribute to beautiful bokeh? What kind of lenses that are most likely to be "bokeh monsters?"? Which vintage and contemporary lenses should bokeh fanatics go for? Just ask me and I'll give you my arrogant but educated opinions-:)
 
Mr. Schneider…I would love to hear your arrogant and educated opinions…

I’m old-school as well…I paid little attention to “bokeh”, even as a professional in the 1990s. The character of the OOF areas concerned me very little. Either something was in focus or it wasn’t. I wouldn’t have known “creamy bokeh” if I had stepped in a puddle of it. I am now much more aware of it because of the attention that it receives.

When planning a shoot, I create a shot list in a notebook and previsualize each image. I list general parameters for each shot including the lens. I now find myself factoring in the OOF qualities when choosing a lens for a particular image. In a quiet portrait of a person with porcelain skin and flowing hair, sharp bubble bokeh will likely distract and draw the viewer’s eye away from the subject. Put the same subject flying a kite in a flowered field with hair blowing in the breeze, a more energetic bokeh may be called for. If I want swirly, bubbly, dreamy or creamy, I have a lens that will produce it, under the right conditions.

Specifics: I recently shot an outdoor environmental portrait of a musician, playing his guitar. The background was dark and out of focus but contained geometry that I used to frame the subject and guide the eyes around the image. It was important that those features and lines be subtle and out of focus, but present. I used a simple AF-S Nikkor 50mm f 1.8G and a Tokina AT-X Pro Macro 100 f2.8D. Both performed predictably and admirably. I also shot film in a Nikon FM2n with my trusty old Ai-converted Nikkor-SC Auto 50mm f1.4. That lens gives me very smooth low-contrast transition (and bubbly specular OOF highlights, but there weren’t any in that shot). I also brought my old Sonnar-formula Ai-converted Nikkor 105mm f2.5 (but I ran out of ambient light and lost the balance with my single strobe). Those four lenses are my go-to lenses for portraits partly because they allow me to use out-of-focus background features as compositional elements without rendering them in a distracting manner.

I don’t judge a type of “bokeh” as inherently good or bad. I see it as either appropriate or inappropriate for a certain image. I generally want it to go unnoticed unless it contributes something to the image. Nevertheless, it is an aesthetic element over which I have complete control through lens choice, distance and aperture.

This.

Everything that is within the borders of a photograph is a compositional part of that photograph. The “out of focus” areas, and how they look, are no less important to the overall effect of the photograph than the “subject”. Not every photo is a portrait or meant to draw our eye to one single thing in a small part of the frame. Sometimes you want creamy, sometimes you want double edged, sometimes you want soap bubbles (even if not often) (or ever).
If someone limits themselves, consciously or unconsciously, to a single style, they may have an innate preference for one single way the out of focus areas are rendered, but different ways of handling those areas will change the effect of the photo on the viewer.
There is no part of a photo, no part of what is in the visible frame, that is less important than any other part. Not every photograph must necessarily “draw the eye” to one part of the frame to the exclusion of other parts, even if there is a shallow DOF. Some yes, some no depending on the intent.

The way that the out of focus areas are rendered in shallow DOF photos has always been important in photography, even before calling it bokeh became a common pastime. It’s not something that just became important recently. It’s part of the frame so it’s important to the impact of your photo regardless if it is out of focus or not. You can creamy those parts of the photo, or double edge them, or bubble them. There may be only one way that an individual “likes” and applies that to everything he does, the one size fits all approach, but different scenes which present themselves to us might be better served by different lenses.
Or just shoot every thing at f/64 and dodge the issue entirely.
I generally prefer “creamy”, but understand it’s not right or wrong, just a personal fixation, and it likely limits me by keeping me from always seeing the photographic possibilities inherent in a given scene.
 
Dante Stella has an interesting viewpoint that I generally agree with. YMMV.

It is a fair view, and the one that the f64 group took, but I kind of think his second image is more "interesting/creative" than the first. If they were my kids or relatives, maybe I would prefer the first. Bokeh can be overdone, and often times I stop down to get more DOF. Bokeh as a gimmic gets boring.

When I shot as as young guy in the 70s, I did not think about "bokeh". I knew about the technical subject of DOF, and I noticed bokeh effects, but did not necessarily relate it back to my specific lens. I was fortunate I guess that I bought my dad's used Zeiss Icarex 35S with the Ultron (the main lens I used at that time by far), so when I noticed effects they tended to be surprisingly interesting or in many cases just creamy bokeh. I though the 35S was a clunky camera but recognized it was a Zeiss lens, so I knew it was "good" (My dad used to say "the camera is just ok, but the lens is excellent"). I really wanted an Olympus, Nikon, Minolta, etc. at the time and felt like the 35S was kind of a second rate camera. Now I am happy to still have the Ultron (not just for bokeh, but for overall rendering, contrast, sharpness, etc.), and have gone mainly M42 for 35mm SLRs.

Perhaps. But which photo will the kids in the photo look back in with more fondness? Not that that is the only criteria of course .... just a thought

I kind of covered that when I said, "If they were my kids or relatives, maybe I would prefer the first". I think what you are asking is a separate question- "What is the purpose of a photograph".
 
While I do think that bokeh is often over hyped and also that, as I said in my other post on this thread composition and subject selection often go further than bokeh in making an interesting and visually captivating image, I do usually shoot with a wide aperture. Partly its a style I prefer but a large part of my object in doing this is that I want to create subject separation rather than a specific type or quality of bokeh per se.

Having said that what's the problem with nice bokeh (a question for those who are not really into it). For example, I shot the following image some time back using according to my records of the time a 90mm Tele Elmarit. Not for bokeh obviously as that lens is not especially known of it so far as I know. But I posted it on Flickr largely because the bokeh was rather pleasant particularly in the far background where to my eye it looks particularly good and in addition, the gradation from sharp to blur is gradual in a way that adds something to the image.

Or this one where the bokeh is especially soft (being shot with a Nikkor 85mm f1.4 in pretty dark conditions). Mind you, as is obvious in this instance, the image has had a texture applied to the background for artistic effect, but when you look beyond this fact a rather painterly and gently soft bokeh is still apparent. It would not have been the same without that bokeh.

City, Evening - Three Amigos by Life in Shadows, on Flickr

Something similar might be said of this one. (I did not record the lens at the time unfortunately, but it was obviously fast and had what are usually regarded as good bokeh characteristics - I suspect but am not sure that it was a Nikkor 105mm lens, possibly f2.5 but maybe an f1.8).

Market Cafe Study 5 by Life in Shadows, on Flickr

In short, most of my images are shot more for subject separation considerations not "bokeh" per se. Or at least I am not pushing for it. But when a lens and subject set up produce pleasant bokeh I regard it as a plus. But then again I am very much of the "artistic" photography camp and not really into reportage, documentary, or even photographing the world as it is. And perhaps this is the real dividing line between people who like bokeh and those for whom its more a matter of "bokeh............ myeh, so what!" And there is nothing particularly wrong with either approach - it all depends on what you set out to achieve.
 
You want delusion in your bokeh? Here you go:


Stream Boulder by P F McFarland, on Flickr

I rebuilt an Agfa Karat, and swear I didn't touch the lens! Well, at least not until I saw this. Someone before me flipped a lens element.

Up to that point my only opinion on bokeh was to avoid the Zeiss swirlies.

PF
 
I want my out of focus rendering to not be distracting and actually unnoticeable. It seems that can be be achieved by a circular iris. Also the lens must produce out of focus circles with soft edges.
Under corrected coma?

This can sometimes be achieved with some lenses but only at certain apertures.
 
Film choice and bokeh

Film choice and bokeh

I like all of them, but was referring especially to the 3 men. I think there were two pictures when I quoted. I removed them from the quote, because it gets overwhelming sometimes to keep quoting all he pictures. I don't think all lenses do well in both foreground and background bokeh.

Interesting thing about bokeh (for me at least), the first time around in photography (many a year ago), I really never thought about bokeh as a standard feature in an image. I mean I was very aware of it, but just did not think of it except in terms of DOF, and clearly (going through my old negs) I was experimenting with it, but at that time had no idea for instance that the Ultron was considered a premier bokeh lens. I suspect if I was using a lens with poor bokeh I would have compensated, maybe by shooting more Tri-X or HP5 for instance. Now I often think about it explicitly as I create an image (unless it is a fast shot), and even consider what lens I am using.

Bokeh is a term that refers to the rendition of the out-of-focus areas of the image--it's an optical phenomenon and is not affected by film choice. Shooting on a "gritty, moderate grainy film" like Kodak Tri-X can contribute to a vintage look, but that's another story entirely. Bokeh is a word that originated in Japan decades ago when serious photographers noticed that some lenses that deliver outstanding sharpness render adjacent out-of-focus areas of the image "harshly" with artifacts instead of providing smooth, natural transitions. Bokeh is a term that takes us back to the day when lens performance was evaluated primarily by looking at images captured by the lens rather than trying to quantify lens performance based on objective measurements such as resolution in lines per millimeter and MTF graphs. Both approaches are valid, and today's best lenses can capture images that are breathtakingly sharp and also have smooth, attractive bokeh. In general the best vintage lenses score on their distinctive rendition and optical "personality" which can be used as a creative artistic tool.
 
Narrowed it down to three :if budget no issue ... 75 1.4 summilux ... 50 1.4 Summilkux pre asph still pricey , or the 50 1.5 LTM Nokton 50 1.5 a bargain !

Is this Destiny or Fate...choose your Card,choose your Saint[/url] by Helen Hill, on Flickr

Great shots. Excellent examples, Helen.
I have a Summilux 75/1.4 and an (inexpensive but excellent) Nokton 50/1.5.

I like the original Nokton and Ultron for the Prominent, plus Zeiss Jena 5cm lenses for nice looking bokeh.

I skipped getting the Summilux 50/1.4 as I have many 50mm lenses.

Sounds like we are merging the "vintage look" and "bokeh" threads (why not? It is related in some ways). I am no expert, but I do notice that when a nice smooth bokeh is achieved, moderate grain can accentuate the effect (you brought up film choice).

Another thing I notice- When I get a vintage lens or lenses in a certain mount, I often start by testing on my digital camera (Fujifilm XT-2) to get a preview of how they perform (and sometimes to use on the digital). I find I often do not like the lens as much on the digital as I do on film cameras. Not just for bokeh, but also in general. I find the bokeh (with no grain) becomes to "sharp" (if you can imagine sharp out of focus effects!), and often more extreme in nature (exaggerated even). Maybe it is partially because I use a crop frame camera, but it seems more fundamental than that. Also flaws get magnified (i.e., I have a Fuji 43-75mm zoom; looked terrible on digital, but renders really nicely on film. Bad chromatic aberration on digital for one). It may be related to the fact that digital sensors do not do well with off-axis (non-normal) rays.
 
Good and bad bokeh

Good and bad bokeh

Hello Jason - I'm a longtime admirer of your writings - back from the Modern Photography, Popular Photography days! I finally was able to get all three of your Camera Collecting books!

For me, the only "bad bokeh" is that which is distracting, cluttered, or "busy" - not sure really what to call it.

Unfortunately, mirror lens "doughnut" bokeh often does this.

Foreground bokeh, if a large enough area, bothers me.

Oddly enough, bokeh where highlights are in the shape of aperture blades, especially 5 blades, is appealing to me. I've seen it so much it seems normal and evokes a certain "night time city life" mood to me.

I do have a 135/2 Defocus Control Nikkor and I have to admit it has produced almost the smoothest softest bokeh I've ever seen. The absolute smoothest is from a 40/2.8 Kilfitt Makro-Kilar D.

I agree that "bad bokeh" is characterized by artifacts (linear patterns, general roughness, etc.) in the out-of-focus areas of an image, and that "good bokeh" is characterized by smooth natural transitions from the in-focus areas to the the out-of-focus areas of in the background or foreground areas adjacent to the main subject, which is usually sharply rendered. Another important criterion of "good bokeh" is that any elements that are out of focus retain the shape of the the original objects and are not distorted. The donut shaped pattern in out of focus areas that are inevitable with mirror (catadioptric) lenses is usually distracting, but with a little ingenuity it can be used to creative effect.
 
Engineering Bokeh into modern lenses

Engineering Bokeh into modern lenses

I guess my favorite kind is non-distracting: Smooth, no sharp edges or patterns.

Don't know what specific elements create it, but seems to me that it's been engineered effectively into lenses like 17/1.2 and 25/1.2 Olympus Zuiko Pro and Sony SEL90M28G macro. Then there's Sony's SEL100F28GM with apodizing element (haven't tried this one personally - I think I have enough large and heavy lenses already).

Many traditional and classic vintage lenses (e.g. the 50mm f/2 Leitz Summer and the 50mm f/1.5 and f/2 Zeiss Sonnars in uncoated prewar and coated postwar versions) were designed with the aid of mathematics (ray tracing) but were evaluated by looking at the quality of the images they captured on film at various apertures and subject distances. The Japanese word bokeh had not been coined yet but it was an unconscious element in evaluating the test images, and that's why many vintage lenses capture beautiful bokeh. Most modern lenses employ computer aided design (CAD) and provide much flatter image fields, better off-axis sharpness at wide apertures, uniform performance over a wider range of object distances thanks to floating elements, and other benefits. However over the last 10 years or so optical designers have incorporated pleasing bokeh into their optical design criteria and have achieved lenses that provide the latest technical improvements along with beautiful bokeh. The 25mm f/1.2 Zuiko in MFT mount you cite, and the 45mm f/2.8 DG DN Sigma in L-mount are two notable examples.
 
Bokeh or pleasant out of focus areas in photos are subjective , yes and many other conditions have to be there for it to happen and it is not always guaranteed to happen.

Some of the lenses that can achieve this sort of thing from my limited experience are the fast Sonnar type lenses...in my case the Canon 50mm f1.5 and certain select Jupiter 3 lenses and in non Sonnar, the 55mm f1.2 Zuiko lens and the 50 mm Rokkor f 1.7 and the 50 mm Leitz Summitar and the 50mm Summar lenses .

Longer lenses that have achieved nice bokeh in my opinion have been the FD Canon 85mm f1.8, the Jupiter 9 lens and the Pentacon 135mm f2.8 and the Zuiko 135mm f2.8 lens and the old Nikkor 105mm f2.5 lens that I have in LTM mount. I love the OOF areas in photos taken by the pre-aspherical Summilux 35mm f1.4 lens...there is something magical that lens imparts to the image...a real wonderful lens .

In TLR lenses the old Zeiss Triotars have impressed me in their 3D and nice bokeh image making qualities. Others will have their own prefered lens selection, no doubt about it.
 
I like it when it is smooth and creamy... And I don’t think quantity (how much the background is washed out) = quality. I really liked Canon 100/2.8 macro lens (original, non usm version). I have sold “king of bokeh” cron 35v4. It was nice somewhat stopped down, but when wide open bokeh was not to my liking (THAT comma). I am now testing Canon 85/1.8 - I have read good words about the bokeh of this lens...
Oh, and the reason I have sold Bessa II (Skopar) - bokeh was somewhat nevous wide open. I was looking for Helian version, but prices are too high now. OTOH I am never disapointed with my Rolleiflex 3.5F Planar bokeh.

I shot this with my Exakta 1, version 2 of 1937 and original uncoated 54mm f/3.5 Exaktar lens (a rebadged Meyer Primotar Tessar-type). Handheld exposure: 1/50 sec at f/4-5.6 on Ilford HP-5 Plus. This image is quite sharp and contrast is relatively high, yet it sure captures that Vintage Look.

I shot this with my Contax IIIa and (coated) 50mm f/1.5 Zeiss-Opton Sonnar. Handheld exposure: 1/250 sec at f/5.6 on Ilford HP-5 Plus. I added sepia tone in post production but the scanned image of the original negative is otherwise unaltered. I think the image has a timeless quality and looks like it could have been taken in the 1950s. I love the way this lens renders 3-dimensional space. By the way Aster is my youngest granddaughter.
