As an active photographer, I still see most people using DSLRs or their phone. Actually, everyone I know who bought into mirrorless actually gave it up.
Back when they were popular I did look into getting one. But there were too many competing lens mounts, and not enough good lenses. So you could buy in to one mount only to have a different mount take over the market, or have yours go away.
Back when they were popular? (Practically?) Every new camera coming out is mirrorless. Every pro is moving to mirrorless. It won’t be all that long before you can’t even buy a new DSLR.
Canon, Sony, and Nikon all have their own mount just as they always have. Canon and Nikon took the opportunity to make theirs larger/better/shorter distance, but you can use adapters to use old glass. As a matter of fact, I don’t even have any Z lenses for my mirrorless body.
Mirrorless is better, full stop. The only real disadvantage is battery life. Some people prefer an OVF, but personally I have a much easier time seeing through an EVF. The jump in focus accuracy is an absolute game changer, and it’s worth switching for that reason alone.
I have a Z8 on the way and then I’ll be fully mirrorless myself, and I can’t wait to ditch what’s largely considered the best DSLR ever made - the D850.
I haven't used one lately, but ten years ago the delay between seeing the image and capturing it was so great that it made them useless for people photography (unless people are posing, but I like to capture real emotions as they are happening).
Are they better now? In my experience, the shutter lag must be close to 0 to be able to capture the right facial expression. Lag ruins pictures.

The downsides are price and battery life, and if you have existing lenses you’ll need an adapter..
The newer ones like the Canon R3 are even faster and the Sony A1 can do 240fps in the EVF.
Another perk of EVFs: they're much brighter indoors as they simulate the actual exposure.
I'm very sensitive to lag to the point where I couldn't play Smash Bros on a friend's TV that he insisted was fine. I'm not sure what the actual numbers are but the EVF latency is for all practical purposes imperceptible, and the cameras can shoot much faster bursts to boot.
Plus, people tend to change their expressions when a shutter/mirror is clacking away and mirrorless cameras can be silent.
DSLRs are worse for capturing the right facial expression in some ways too, because the mirror flip temporarily blocks the viewfinder. With an electronic shutter enabled, a wedding photographer on mirrorless will never have the viewfinder blackout during burst shots when trying to capture "the moment". The mirror/shutterbox puts the "real" world lag on many DSLRs in the 60-120ms range, which is not so hard for an electronic viewfinder to get competitive with.
Mirrorless models with electronic shutters in theory also have the option to continually "precapture" and then use an image from say 100ms ago when button pressed - the iPhone does this to reduce lag time even more, and try to eliminate human response time from the process. A DSLR can only do this concept if the mirror was up blocking the view finder.
While people assume that there is a degree of "WYSIWYG" with the mirror, this isn't always 100% true either. Cheaper/small prisms or pentamirrors result in much dimmer and smaller viewfinders than a good electronic viewfinder, especially on APS-C sized sensors, and 100 percent view coverage is rare outside of high end ones. AFAIK all electronic viewfinders to date are generally 100 percent coverage, and often bigger.
One enormous benefit for wedding/event photographers that mirror elimination accomplishes is making the camera silent. A high end DSLR operating at its highest burst speed is very noisy as the mirror slaps back and forth, which genuinely can be problematic in quiet or intimate settings. The mirror boxes also generally are only good for typically 100-150k activations, which lasts a long time, but they can wear out.
False! Pentax is sticking to DSLR ;)
Paired with an AC power adapter and a mount for my monitor it's a nice webcam. I bought a 24mm lens for it that was reasonably affordable and I get a nice "real" bokeh effect in my background (it's not as blurry as the computational one but it's a nice to have). (FWIW I also push it through OBS to crop it).
Most of them were only specced to record up to 30 minute clips at a time in original guise and are passively cooled, so running for an hr or more can push the sensors beyond their original specifications etc. I've had this happen rarely with some m43 cameras I use as webcams via an HDMI capture card. There's a ton of youtube videos on this topic with all sorts of homemade cooling setups:
While it looks like your camera is supported by both versions, maybe you'll have better luck with this one.
What is this alluding to? Bingle are not helping.
They’re cheaper but you have to carry an adapter.
Editors never ask me "what camera did you use?". They evaluate images based upon impact.
This moment in the camera market seems really interesting to me because we have phone cameras becoming more and more capable thus shrinking the DSLR/Mirrorless market exponentially. High end cameras are getting more expensive. Where is it all going?
These are definitely a good choice for taking good pictures
this is still a huge amount of money, to me.
This camera setup for personal social events is a great idea, I wonder if it could be done with some sort of phone app so among a group of friends or at a party you could use everybody's cell phone.
in watching the video though, I found it a little disappointing. I think people need help with choreography, what actions and timing are going to make for good shifts in perspective. For example, you want grandma to rotate in mid air, not something she throws up. Another example, I think you want the action to start from the periphery, and then bring the characters in the shot "into the spotlight" so the clip delivers a climax or "keeps getting better". (although, he did use the "move away from the action" technique to good effect to create transition places to stitch together a series of clips into a sequence https://there.oughta.be/assets/images/2023-05-26/demo-blog.m... )
And could it be done using video instead of still shots? seems like turning raw footage into something interesting would be easier? Or is that how it works anyway?
Strip light can then be put into any flexible pattern you want and strung pretty much wherever, or taped to pretty much any location. Whole thing could probably have almost the same electronics size as one of those common color changing LED strips.
Link 2: “ For my cousin’s wedding I did not make a photo booth but a video booth.”
That’s n = 2 for cousins getting married inspiring bullet cam implementations.
I first saw this at an art installation in Brooklyn in 2017.
The resulting shot was a little choppy but novel.
EDIT: Turns out that the director, Gerry Cook, has a youtube channel with quite a bit of his work shown there. In particular, there is a Heck Yes Productions demo reel, where at 1:50, there is a ring cam shot of a girl jumping rope. It is very similar to the ABC Baseball ring shot but done in the weeks following the baseball shot.
I think this is it:

Not quite as many radians without the subject moving as you would with the real thing.
This is getting pretty complicated though, he “hard-coded” the camera motion into the shape of the frame. Physical things are hard, haha.

it's a bit weird because it often turns out that cameras with user interfaces are cheaper because of economy of scales. that being said, a market for almost barbone sensors on pcb's seems to be building and is lead by raspberry pi's camera modules, where the hq module has a reasonably sized sensor but is still a far cry from mft, aps-c and full frame sizes. the hq camera is almost on parity with most phones. from there it pretty much moves into cameras with ui's but controllable with some kind of vendor sdk or libgphoto. i imagine it's a matter of economy of scale and it's almost impossible to buy a good almost barbone sensor. If it's even possible e.g. the 61mp ff sensor used in the Sony a7rV is available almost barbone for astro photography, it's still very expensive. i imagine there's a pretty big market for all kinds of industrial cameras but from tip toeing into that, it seems very very very expensive.
The entertainment new channel E! Is well established in this space. I have to wonder at what point a low cost arm is cheaper than an array of cameras.
But much cheaper to put a camera on a rail/track instead of complex motion control.
Just do a quick search on that term and you will find a whole bunch of videos that reconstruct 3d scenes using digital stills. I just saw a paper a couple of days ago showing advances in reconstructing human expressions that change over time using advanced techniques.
Neural Holography should arrive to market within the the next 6 months, which will allow for any frame to be seen at any angle with as few as 20 cameras for 360° x 180° coverage, allowing for bullet time shots to be designed after the fact with the added bonus of having cinematic quality 3D live action content for use in VR and other 3D environments.
I fully remember I left for the bathroom and came back to my girlfriend and her bestie doing it, it was like you stood in the Center of the platform and the cameras rotated around or something?
I wish I could remember it more specifically, and it wasn’t perfect; but it struck me as strange that this was the first time I’d actually seen anyone even try!
Wish now I’d written down the company who was putting it on. It looked neat. :)
And there was a lens for this kind of effect, it allowed capturing three images at once [1] [2].
There were also dedicated cameras [3].
> Using its four lenses, four images from slightly different viewing angles were taken simultaneously. With the individual images half the size of the usual 35mm image frames, each 3D photograph taken used the space of 2 full 35mm exposures on the film. So a roll labeled as "36 exposures" would yield 18 3D pictures with four images each.

If you want to obtain the same effect with way less cameras, 4 maybe, check the paper 'Real-Time Depth Video-Based Rendering for 6-DoF HMD Navigation and Light Field Displays' (Bonatto 2021)[0], the supplementary material contains the video view synthesis [1]and some results can be found on YouTube [2] and finally..
You can do the view synthesis for free using the (MPEG) free software: RVS (reference view synthesizer) [3].

Then chopping the single capture into smaller frames one bit for each mirror, each with a different view of the subject, and stitch them into a video.
I can imagine a 3x1 layout but trying to arrange the mirrors in a curve so the camera sees a 3x3 or 4x4 or 5x5 arrangement might need some optical cleverness.
actually I think one can already see it in this ad from 1996: https://www.youtube.com/watch?v=qbOGJy3P6rA
It's not abundantly hard to bang together something functional, really. It's one of those projects where you just think about the components you have (Camera, Monitor), and then make an enclosure (or find 3d/laser files), then some code that's surely on github to sync them together.
Got me thinking now what a tiny printing solution like that would/could look like!
EDIT: unsurprisingly, there’s a bunch of iOS/iPadOS solutions. You could theoretically base it off a custom app on an iPad with one of these iThing printers stuffed away and use Square as a POS?
