That doesn't quite explain the modern f/1.4 - f/1.8 primes we see pop up all the time specifically for mirrorless camera systems.

It;s an ego thing or they're not aware of how small DOF is at such large apertures. Also, you carry around a heavier lens that costs more because of all that extra glass.

If you shoot a "standard" 50mm at f/1.4 on a full frame camera of someone's upper body from 5 feet, (roughly 2 1/2' x 3 1/2' field of view) you only have less than 3" DOF. That's less than 1 1/2" in front and in back of the focal point. So if you focus on the eyes, the subject's ears and tip of the nose will be out of focus. IF his head is at an angle, the second eye will also be out of focus. IF your focus is slightly off, even the eyes will be out of focus. f/4.0 will give you about 8" DOF.

In fairness, at ten feet, the field of view of 5' x 7' approx, you have almost a 12" DOF at f/1.4. SO you may want that. But in most cases, f/1.4 just isn;t needed with modern cameras as much as the old low ISO film SLRs with OVFs.

I'm not so sure. That sounds like a bit of a harsh judgement on the decision making of people you apparently didn't know that existed.

Most of the arguments I see from them are in the direction of the quality of unshrapness rendering (bokeh), the ability to use relatively low ISO even under adverse lighting conditions but also other attributes of the lens that do not directly relate to the maximum aperture, like build quality, focus speed/precision etc.

As to the argument of "need": most photos aren't really needed anyway. That argument almost never goes anywhere. Most of us do it for enjoyment; it's inherently irrational.
 
I can visualize a resulting print or slide far more effectively using an optical viewfinder image - which I have decades of experience with - than if presented with the image on what amounts to a very close, very small computer screen.
I expect most reasonably competent film photographers would be in the same boat.
Perhaps you are aiming your product idea at photographers who are only just moving to film from earlier experience with digital cameras with EVFs or nothing but live view on a screen. If so, I don't know whether that will help them with the transition to film or not - I expect it might actually impede the process.
One chooses a viewing system based on how well one uses it to visualize the result.
Histograms and the like are probably useful additions, but not if they get in the way of seeing + visualizing.
Garry Winogrand's line comes to mind:
"I photograph to see what the world looks like photographed"
Optical viewfinders seem to do a bit better job of giving most of us here a bit better of a sneak peek of the result ahead of time.

👍 One of the key factors in judging DOF is the acuity of human vision to detect blur circles ('blurry'rather than be fooled into assessing a blur circle as a perceived 'dot' ('sharp' enough). It is a know fact that standard 'manufacturer DOF' assumes human visual acuity which is WORSE than what optometrists around the world aim to achieve in correcting our vision...human eyes can detect one half minute of arc! The assumption behind DOF tables and most programs is not 20/20 vision (6/6 in Europe), so they typical DOF table is a LIE vs. the reality of what the person with 20/20 actually sees in an 8x10" photo assessed from a viewing distance of 10". It is well known that the EVF of most cameras presents fewer pixels than our cameras capture...IOW the resolution of the EVF is not as good as it needs to be...the presentation of the CofC in the viewfinder itself is NOT a precise presentation by the limitations of the resolution of the LCD. Admittedly even the OVF of the typical dSLR lies to us, as the coarseness of the standard dSLR screen only permits good assessment of focus equivalent to f/4 lens at best, not the f/1.4 lens which might be mounted.
As for presentation of an image with 'accuracy' to reflect what is captured, even that is 'colored' by whatever parameters are in effect to process RAW into viewable JPG on the LCD, and those parameters are not matching the parameters we choose to use during RAW conversion and postprocessing back at home! IOW, yet another visual LIE from the reality of the final print.
Yes, an EVF presents much more than is presented in any film viewfinder in real time, relative to the final print. But the OVF is a better presentation of realtime reality of the scene itself than an EVF over the false reality of the EVF mimicing the captured image, even though the film SLR presents nothing relative to the captured image. And that is what is appealing to most photographers expressing the preference of the OVF over a pricey EVF retrofit.
 
The push for very bright and expensive lenses has really been eliminated with EVF and high ISO sensors used in mirrorless digital cameras.

but the EVF and high ISO capture does not eliminate the desire for the isolations permitted by extremely shallow DOF, which is one reason for the f/1.4 lens. And desired precision of focus, even using autofocus, is inherently better from the shallower DOF using larger focusing aperture. And the larger shooting aperture will permit better motion freezing than what a smaller max aperture lens would force in the same low light conditions. The reason for big apertures is lessened but not 'eliminated' as stated.

I probably was too harsh. But I was thinking back before digital. There always was this competition of who had the brightest lens (or fastest shutter speed camera, or some other feature the other manufacturers didn't have). . The manufacturers used this to convince buyers they needed more expensive lenses and cameras with features rarely used.

Hardy. Anyone practicing 35mm photojournalism without flash heavily depended upon large aperture lenses to simply get the shot. Shooting with ISO 400 could often entail 1/30 f/2 (or even less light) and I yearned to afford 50mm f/1.4 in those conditions. Working for an organization that made possible the use of Canon f/0.95 was a fantasy. Forced to use f/3.5 in telephoto or WA FL made f/2 something of dreams.

I see what you mean, though. Maybe the EVF movement has rekindled old habits. I'm not sure; I haven't really followed it much, I only noticed fast primes being introduced as of late a lot, often by Chinese 3rd party manufacturers (some of them really good, too).
 
...but then it could not be 'mirrorless', because the mirror is needed for optical path to eye. At the minimum, we are back to the pellicle (Canon Pellix or Canon RT) and its issues.

Why? I have dozens of cameras that have OVFs that have no mirrors.

single lens REFLEX cameras? means viewing thru the taking lens, so you need a mirror (which moves out of the way, or a pellicle) to expose film/sensor and/or to divert light to the eye
 
People will pay $50 for a roll of Velvia, and $30 for processing and ordinary scans. Same folks aren't going to pay over 2 K for a non-Leica new film camera.

It's the Rolex watch crowd now. Made in Germany.

It would be cool to see. You need volume production.

I would have agreed with you several years ago, but the Pentax 17 blew this assumption out of the water I think quite plainly. Which is what made me think along these lines and others. And that was for a camera with almost no distinguishing advantages vs cheap ebay vintage stuff, let alone actual unique new powerful feeatures.

Hardly 'taking the industry storm'

The fact that the resale value of the old DSLRs has since plummeted down to like $200 for most models that used to be 10x that squarely rules otu the hypothesis that "Yeah it's high market share now but only because all the photogs are yearning for and staying with DSLRs" If that were true, then supply drying up + demand staying full would = a huge huge spike UP in DSLR prices, not a crash. Your contention meanwhile that most people switched to film is just not at all true, what? Where'd you get that from? Googling 2025, I get answers hovering around 2.5 billion for film photography, and around 70 billion for digital (which is overwhelmingly mirrorless)
I can visualize a resulting print or slide far more effectively using an optical viewfinder image - which I have decades of experience with - than if presented with the image on what amounts to a very close, very small computer screen.

Your decades of experience would apply equally well to elaborating upon/extrapolating the image in an EVF just like they apply to elaborating upon the image in an OVF. So don't really apply to this comparison since it cancels out of the equation on both sides. There would have to be something in the EVF that negated the experience from being possible to apply, but there simply isn't any such thing--it's not even possible these days for the large majority of photographers to make out any pixels in EVFs anymore (not that such a subtle thing if you can would make any sense as negating all your experience). The colors starting out closer to what a final slide will look like cannot sensibly be argued to somehow make it harder to visualize further to the exact slide. This is like saying that having a step ladder somehow makes you able to reach less high.

I think part of the friction in this thread boils down to a tendency captured here: to regard one's own, personal preferences as universal.

It's nearly universal based on hard data from the industry, not any assumptions.
  • Mirrorless has taken over at least 90% of the new cameras. Pentax still sells one single DSLR line and I think that's it AFAIK, yes?
  • The used DLSRs rather than spiking up in price as would happen if demand remained high but supply slumped, have instead done the opposite. Prices have plummeted to single digit fractions of their original, suggesting that demand has fallen even faster than the already steeply falling supply.
  • The mirrorless cameras aren't any cheaper, they're about the same (and a new ecosystem on top + any adapters etc pushes it into "more expensive"), so there would be no other incentive for consumers to switch to them other than actually preferring the new tech.
Some (other) people who use film appear to visualize the result they are aiming for mentally and arguably would be hindered or biased by a machine-made preview that does not interpret the scene on the basis of a human emotional response to it.

I am not following your logic here at all. Again this is essentially "a step stool would make it harder for me to reach higher". Obviously something closer to the final result makes it easier to stretch the remaining distance in your head, not harder. And the emotional thing ?? the film itself doesn't respond to your emotions either, so what are you talking about? If you don't actively change settings or location or time of shooting to create the emotions in the image yourself, they ain't getting down on film OR sensor preview. And if you do actively make them show up, then you will see the emotionally relevant changes in the preview as a result of your actions to change the shot, prior to hitting the button. Which clearly makes it harder to whiff on creating the technical conditions you qualitatively consider emotional: you can check and see if you succeeded prior to spending the film. So of course you'd fail less often.


Camera's with electronic viewfinders have been around for decades now. If there would have been merit to a Frankenstein concept that records on film but uses a digital display to approximate the final image, surely, companies would have invested in it.

This is the first time both halves of the equation have been properly viable.

EVFs were absolute garbage until a few years ago, with super low framerates, poor resolution, etc. The modern ones have eliminated whole laundry lists of downsides to zero by not even being able to perceive the pixels anymore for most people, and definitely not being able to physically perceive the sub millisecond lag in normal lighting. While ironing out what features people like in them (peaking, etc). The rise of mirrorless cameras less than one decade ago instead of many decades ago, directly coincides with when EVFs became not garbage, as a causal relationship.
But by that time, the film half of the equation was considered dead. Only just a couple years ago with the Pentax 17 especially has that proven to also be viable, and for the first time, we have both halves viable at once.
 
Where'd you get that from? Googling 2025, I get answers hovering around 2.5 billion for film photography, and around 70 billion for digital (which is overwhelmingly mirrorless)
CIPA (Japan Camera & Imaging Products Association, established 2002) statistics for cameras manufactured in Japan and sold worldwide...a Japanese trade organization that has statustics since 1951 (and I have that data). about camera & lens shipments, in units and in monetary value.
In 2025, 6.3 Million mirrorless, of 9.4 Million total (none film). In 2012, mirrorless shipped 3.94 Million, SLRs shipped 16.2 Million

'Billions'? what are your statistics representing, total units ever sold?
Your interpretation of what I said or implied is a serious misinterpretation BTW. To restate:
Mirrorless growing from 4 Million units to 6.3 Million over a period of 13 years is AAGR of 4%, hardly stunning growth, it did OK in view of cameras in general shrinking from 16 Million to 9 Million, but it is still survival in face of extinction. They have on overwhelming share (67%) of a dying market.​
Even the industry CEOs understand that, and have admitted how dire the picture is. At its peak, Palm had 80% market share...where are they now?

It still is a computer screen that emits an image, rather than a focusing screen, that relies on the light that hits it to form an image.
Just as fundamentally different as a print and an image on a computer screen, although in different ways.
We observe images in very different ways when there are such fundamental differences in how they are presented.

I never said anything about reflex. Why would you need a reflex? Mirrorless cameras have no reflex. Slapping an EVF on a camera doesn't need any sort of reflex. I don't recall anyone saying it had to be TTL viewing.

Carry on.

👍 Somthing else for Crimeo to ponder: The world has abandoned increased precision in audio (CD qualilty) for the convenience of MP3...and ignored 12" woofer with their spectacular and accurate bass reproduction for the convenience of the 3" Bluetooth speaker.
  • Will they want to add the inconvenience of EVF (form factor, short battery life) in place of the convenience of the OVF?
  • Will there be sufficient perceived advantages in EVF to overcome the cost and disadvantages of EVF?
Do you think you convince a company to make the product and take it to market?...it is not us that you need to convince.

It is the OP that is trying to suggest the wisom of taking the SLR and adding an EVF, for his perceived advantages of the EVF.
"The goal is a film camera and film photos, just with an EVF for previewing the shot".​
Why would he want to add an EVF to a TLR, or a rangefinder...it would not be seeing what the film exposing lens presents to the film, would it?
(And, adding confusion, you yourself have expressed preference for the OVF....and the world already expressed preference for OVF SLR over OVF rangefinder 35mm long ago...)

OK, say I'm in. Leverage as much as possible.

Let's use Nikon or Canon

Needs to be an autofocus camera, Z mount for Nikon, EVF best possible, image stabilization (not sure that's possible ???), Leverage Z6III, I suppose use standard 135 DX cassettes. Wild, would be cool. Would 50,000 people buy this in the first 2 years, then another 100,000 over the life of the camera? Probably would cost $4,000 (USD)

I can buy an adapter that allows me to use F mount lenses.

Sign me up.

EVF would have a massive advantaged over OVF for film specifically. You can proof the shot based of the preview before shooting and decide if you want to commit to film or adjust the settings.
 
EVF in a film camera is an interesting concept, I have also thought about it before. I guess it's a bit overly complicated and probably expensive solution to a minor problem. I think it would be pretty popular with people getting into analog photography from digital, or maybe among the younger photographers using film for commercial shoots. If it were to come to market however, the cost would probably not be worth it for most people.

If we build on the concept a bit, we may be able to create a more worthwhile product. What about a camera that shoots film and digital at the same time? I this offers a few more reasons to merit production that simply a film camera with EVF.
  • Digital backup incase dev is mishandled. Good insurance when doing a paid job on film.
  • Can work as a sort of polaroid-back situation where you shoot in digital to get lighting and settings right before shooting your film.
  • Can shoot color and BW at same time.
  • Can be a great tool for learning how to make accurate color LUTs and simulations comparing the digital and analog results taken at same time with same settings.
  • Can video and take stills at same time.
  • Can continue to take digital photos once roll of film is done or analog photos if battery dies. (although no viewfinder)
Still a bit gimmicky but I think it would make a fun and interesting tool to use.
The easiest configuration would probably be as a TLR, which the only downside would be parallax error.
  • Replace the ground glass with a live view screen and the mirror with a sensor
  • Sensor uses an electronic shutter
  • Have a setting to operate shutters in tandem or separately
  • Add a battery and CF card slot somewhere.
  • Rework film advance for 35mm film
I think a prototype using an old 120 or 127 TLR wouldn't be too complicated for someone who knows electronics.
It also has the advantage of the ground glass image no longer being flipped.

The system still has its flaws but could be interesting to explore.

The fundamental concept makes sense. But OP was wondering 'why not' (the title of the thread)...
  • would a company develop it,
  • would they make sufficient money to make the effort worthwhile to invest in, and
  • would you (the Photri membership) buy it?
 
this thread is now 5 pages deep and I have not searched it all so if someone already said this - sorry ....
why not a rangefinder concept where the big lens goes to the film and a small lens feeds either an EVF or a back screen? This seems like a doable hybrid?

In fact what if it was an iPhone accessory? Where the 2 items "snapped" together and communicated with one another? Press the shutter button and the iPhone grabs a digital copy and the Camera Accessory captures it on film. Aperture and focus are sent to the iPhone for it to be "replicated" digitally...

Perfect. I would like it in a Fuji GW690III
