Instead, what I got was one of these milquetoast clickbait articles whose headline poses a legitimate question that a reasonably sized audience would be interested to learn the answer to, but whose body contains literally no answer at all and instead rehashes facts that nearly any literate person probably already knows and defers to the reader’s personal judgment.

I have owned a good number of f/2.8 (and wider) lenses in my life, so I wanted to put this to a statistical test. Fortunately, I have also used Lightroom since it was in beta, and I have one giant catalog, so this is an answer that I can get.

Nikon Small World is regarded as the leading forum for showcasing the beauty and complexity of life as seen through the light microscope. The Photomicrography Competition is open to anyone with an interest in microscopy and photography. The video competition, entitled Small World In Motion encompasses any movie or digital time-lapse photography taken through the microscope.

To recognize the more than 360,000 people who will be diagnosed with breast cancer in 2024, Nikon Instruments conducted an interview with 2023 Small World winner Malgorzata Lisowska.

In 2011, Nikon announced that it would begin accepting movies taken through the microscope as a new category in the 37th annual Nikon Small World Photomicrography Competition. This new category, titled Small World in Motion, encompasses any movie or digital time-lapse photography taken through the microscope and adds a new, distinct discipline to the competition.

For me, that extra few stops of light wasn’t worth $1,100. Plus, the f/2.8 is much heavier, which is true of all f/2.8 lenses thanks to the number of lens elements required to make that wide-open aperture sharp and consistent. Believe me, the f/4 is heavy enough after you’ve been carrying it around all day.

Here’s the thing, guys, if you need a lens with an f/2.8 or larger aperture, you already know it, so why are you reading this article? Perhaps you suspect that I’ll talk you out of it somehow, teach you something you don’t know about the fundamental physics of light and save you a few bucks.

For some lenses, the f/2.8 version is weather-sealed and the others are not. This does tend to be the case with ones like the Sony where the f/2.8 is their “G Master” version (equivalent to Canon “L” or Nikon “Nikkor”). Again, do your research. I’ve taken non-weather-sealed cameras and lenses under the base of waterfalls and been fine, but it depends on the kind of work you do.

Is that additional aperture worth $850 to you? Perhaps it is. In the 70-200mm focal length the difference is even more stark: the Sony FE 70-200mm f/4 G sells now for $1,500 while the Sony FE 70-200mm f/2.8 GM is a whopping $2,600.

So that’s my take; I really don’t think most people actually need apertures wider than f/4, and I would encourage anyone on the fence about it to just save the cash and spend it on something else that you know you’ll use.

There are a couple of reasons you may want to pick up the f/2.8 version of a lens, and it’s up to you to determine whether it’s worth the extra cost:

Well, sorry to let you down, but I won’t be breaking any laws of physics today. But if you’re here because you’re actually not sure if you should spring for that fancy and expensive f/2.8 lens, I think I can talk you out of it, unlike Nando Harmsen of Fstoppers, who decidedly expressed almost no opinion at all.

My catalog contains a total of 53,794 photos. Of those, 41,090 were shot at f/4 or higher (that’s 76%)! The number of photos I’ve shot at f/2.8 exactly is only 4,811.

The point that I’m trying to get across here is that if you are unsure whether you should spring for that f/2.8 lens, which in many cases may cost twice as much as the f/4 version of the same lens, because you are concerned that without that range of aperture wider than f/4 there will be shots you will miss, I think you should save the money.

As a concrete point of comparison, let’s look at the Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS (a lens with a completely ridiculous name) versus the Sony FE 16-35 f/2.8 GM. These lenses are both very well-reviewed and are equivalent in nearly all performance aspects, but the f/4 sells right now on B&H for $1,350 while the f/2.8 goes for $2,200.

I have gone on a great many trips with f/2.8 lenses and mostly stopped them down to somewhere between f/2.8 and f/4, or beyond f/4. In my catalog I have only 1,378 photos shot between f/2.8 and f/4 (exclusive), which is only 2.5% of all of my photos, almost a statistical anomaly.

If you are deeply into portraiture or astrophotography, you need that huge light opening or the soft bokeh. Again, I think you probably know that already and wouldn’t be reading this if you were sure, but I mention it for maximum clarity.

For some lenses, the f/2.8 version is sharper or has better color or autofocus overall. That is not the case with the Sony models I listed, but may be true for others, so do your research. Whether those differences matter to you depend a lot on the style of photography you’re into.

The November 2024 cover of Nature Methods features a fluorescence image of a mouse small intestine section captured by Dr. Amy Engevik of the Medical University of South Carolina, which won 4th place in this year’s Nikon Small World Photomicrography Competition.

In my opinion, the majority of people don’t actually need an f/2.8 (or faster) lens. The chances are pretty good that even if you have one, you shoot wide open with it pretty infrequently. If your particular business or artistic interest lives in that zone of luscious bokeh or low-light performance, you already know that and nothing I say should change your mind here.

But, if you shoot a variety of subjects, and mostly during the day, and you have a camera made in the last five or even ten years, you probably can get by with f/4. Again, if you’re someone who is absolutely obsessed with that luxuriously smooth bokeh, then you know this already and you should stop reading.

That Fstoppers article appeared in one of my headline feeds and, as someone who has struggled with this question himself, and who carries with him most of the time an f/4 lens, I wanted to be convinced one way or the other.

The Nikon Small World Competition first began in 1975 as a means to recognize and applaud the efforts of those involved with photography through the light microscope. Since then, Small World has become a leading showcase for photomicrographers from the widest array of scientific disciplines.
