Like the title says. Get below 1.8? F2?

What's the cutoff for you guys that are just serious hobbyists? I've got one that's a 1.4, which is about as fast as I can afford.

I saw several on-line that were below f1! Holy batshit, Batman!

I have a couple of 1.8’s. A 50 and an 85. I rarely shoot that open since dof is almost nil at 1.8. At 1.4 or faster you’d best NAIL exactly what you want in focus because everything else is blurred. Sometimes you want that. But for my purposes it’s pretty rare.

I just started out this year With a rebel t7i, so my fastest is the 50mm 1.8 canon, the rest are all 3+

I’d like to buy a few more lenses, but I feel that when/if I decide to upgrade to a new camera body In a few years I will be moving to a mirrorless. So I don’t want to invest in a bunch of good glass and then buy a new camera that uses a different mount. I know canon has the ef/rf adapter so it could still be very usable but not ideal.

I have the 105 f/1.4 and it's fantastic,... LOVE the compression.   If you can nail focus wide open it's great if your background is cluttered or too distracting.

Canon 50mm 1.4. I honestly don't use it a ton, because on a crop sensor it's more like an 80mm. That cuts off some chromatic aberration on the edges, though, which is nice.

The slowest I can really go for my stuff is 2.8. The fastest lens I have is a Sigma 50mm F1.4 art lens. It's amazing. Sharpness which blows my L series zooms away and the light is pretty great too. Most of the time I'm using my 16-35 V3 L lens. I'll probably get a 5DIV when they get cheap in a year or two. Then I'll make the jump to mirrorless which will bring about more crazy fast glass. A lot of the Canon RF mount lenses are very fast.

I have a 1.4 lens, but it's manual focus and I don't really use it. I do use 1.8s very frequently, have 35, 50, and 85 as well as a Sigma 50-100. Several 2.8 zooms.

f2.8 is my fastest glass.

I was looking at 50mm 1.4 and even the 1.2, but then realized that I have little interest in shooting indoors, portraiture, etc. I'm an outside shooter. So my 17-55 F/2.8 and 50mm F/1.8 are more than fast enough for what little low light stuff I do. And I have the 70-200 F/2.8 for longer focal lengths.

I don't carry or use either of my 70-200s (2.8 and 4), but I want to try to shoot some of the local indoor horse barrel-riding, team-roping, etc events indoors this year. I've never been into all of that "western cowboy crap" that I've been pummeled with for my entire life living here in WY and MT. But I think that some balls-out horse action would be pretty badass to catch on camera. I'm thinking mainly about some cool, crazy horse facial expressions. Not really all that interested in the cowboy/cowgirl expressions. LOL.

Exactly. That was a big part of why I bagged-out on getting anything faster than 1.8. It's hard enough to nail the focus on many shots with my 50 1.8 with that. Shallow DoF certainly has its uses, but few few that I'm interested-in.

f/1.8 is my current fastest, but I'd swear there is an old manual 50mm f/1.2 floating around the house somewhere.  Been trying to find it to see if f/1.4 would be enough of an increase in light that I could drop my ISO to a less insane number for aurora video.

My dream is to rig up a setup for real time 360 aurora video, but short of something custom or even with it, I might as well start selling organs.

For my Nikon DSLRs:

50mm f/1.4 - originally got it when still shooting DX bodies but 35mm would have been better had that been an option. f/1.4 is great for low light. It is also a very thin DOF, which may or may not be a good thing depending on your artistic needs. I don't use it that much lately, but its small size can be handy.

All my pro level zooms are f/2.8 (17-55mm DX, 24-70mm FX, VR 70-200mm II).  Great for low light, like high school gyms, and shallow DOF.

I also have a few consumer grade zooms with variable max apertures. Makes for lighter weight vacation lenses when I don't want the size and weight of the f/2.8 zooms.

My wife has a 50 1.2L and 50 1.8
The 1.2 is stupid sharp but heavy. It lets crazy amounts of light through. It's awesome for dark weddings.

But the depth of field is so shallow if up close to the subject. If she takes a portait of a person and focuses on one eye, the other eye wont be tack sharp.  She's lost shots because her camera focused on an eyelash in front of the pupil.

I think the nifty 50 (50 1.8) is more than sharp enough...and I don't feel crazy nervous taking it around cities or scrambling on mountains.
The 1.8 is also 10-15x cheaper than the 1.2L, way lighter and does most of what the 1.2L does.

I have a Sony APS-C/DX A6600, I have a fixed 35mm f/1.8 for low-light, this is the equiv to 55mm in FX. I want to get a Sigma 16mm F/1.4 if it gets a bit cheaper. I shoot mainly stage plays at my local HS, most of the time my Sony zoom lenses are more than suffice, BUT occassionally I do need the extra f-stop or 2, otherwise the high ISOs are intolerable because of the high sensor noise.

I spent years coveting Canon's 50L 1.2, then saw that they even had a 1.0.
Those are Canon's way of saying "you have too much money, give us some"
Currently my fastest is the 135L 2.0.

"Requiring" & "wanting" are two vastly different things, IMO.  

It may be my lack of knowledge & talent(s), but I would love to own a lens that they use to capture a bullet leaving the barrel of a gun, for example. I can't afford anything like that, obviously. But it's nice to dream.

I would love to be able to see a crystal ball 50-75 years into the future, to see what lenses would like like then.

Small confession here...
In the military, a favorite among military photographers (of which I am formerly) is to catch the cannon shell, sabot, mortar round, etc. in mid flight just as it exits the barrel. It requires a fairly fast shutter speed but doesn't require an especially fast lens.
I completed my career without a single "round in flight" image because I preferred staying down in the bunker because my first outing trying to do that, the missile came up off the rail and exploded, spraying shrapnel everywhere, narrowly missing myself and the commander.
With a fairly fast shutter speed, coupled with continuous shutter operation tends to compensate slightly for light camera shake.

I've caught bullets leaving the barrels of guns.  But their just lines.  No detail.  Sometimes, it's pretty cool, other times, it's hard to see and doesn't add much to the shot.

If you want to catch a bullet leaving a barrel and have it "stopped", you're going to need more than a lens that will get that shot.

I've tried the Canon 85mm f/1.2L.  INSANELY nice.

But the super-low aperture gets interesting... if your subject isn't nicely square to the camera, you can only keep one eye in focus at a time....

I don’t think lenses are going to get much better, I do think they will get smaller though, it’s already happening with some of the new canon rf mount lenses.

What I do feel the future will hold is more artificial intelligence in camera. I think things like using a higher f stop to get multiple people in focus and ai takes over to give that shallow depth of field  bokeh look of being wide open while keeping the people sharp, or ai focus stacking on steroids where the camera can recognize each person and take a series of pictures automatically focusing on each person individually and merging them in camera.

I started photography in the film world years ago. When I/we say a "fast" lens it means a lens with a big ID ie the smaller the number, and of course a "slow" larger number means a lens mean a smaller ID.

IMHO the definition of a "fast" lens break off is a F/2.0 or lower, ie f/1.7, f/1.8 etc is a fast lens. And of course a F/0.95 will suck my camera in.

Back in those days, the cat's meow was the Leitz f/0.95 Noctilux, and the Summilux f/1.2 & f/1.4, and the Zeiss Planar f/1.4 for 35mm cameras. And of course there was the Canon f/0.95 on their rangerfinder camera. Back then aspheric surface lenses was real big deal because it was really, really tough to grind, and only Lietz brought that technology to market.

The Leitz lenses were assembled so that each lens element would cancel out the "tolerance stacking," pretty SotA stuff way back then when computers were in the realm of multi-million corporations.

Of course with today's modern computers, materials, rare-earth glasses, and anti-reflection coatings, those are not a big deal.

It all depends on what you work with and what you need. I was just astonishingly disappointed the other day when I looked down, confused by how dark the image looked on the back of the camera, only to realize that someone had swapped lenses on the body I was using and it "only" went down to 2.8. It's all relative.

2.8 is fast at that long of a telephoto. Nikon has an f2.0 200mm, but I'm not thinking of anything faster than 2.8 at 300mm. The 200/2 is a big lens. Wish I could afford one.

Mine is that old standby, the DX 35mm f/1.8.

I rarely use it; got it because it's incredibly cheap and pretty damn sharp and it approximates the nifty 50 in FX.

Next up would be the Tokina 11-20 f/2.8.  Solves all my wide-angle needs.

Then there's the 24-120 f/4; my all-around workhorse lens.  The more I use it the more I like it.  If I could have only one lens it would be this one.

My fastest are a 17mm f/1.8, a 12mm f/2.0 and a 25mm f/1.7.  The zooms are a 12-40mm f/2.8 and a 12-100 f/4.

The latter two zooms are "pro" level lenses. The primes aren't "pro", but they are all pretty damn good.

I use them on an Olympus OM-D E-M5 MkIII. The IBIS is amazing. This camera will put others to shame with how slow I can run the shutter and still get stupid crisp images. Down in the Carlsbad Caverns, I took it with the 17mm f/1.8. I think I only pushed the ISO to 1600 on a few shots, mostly shooting at f/2-2.2. I don't think my shutter speeds ever got slower than 1/60 or maybe 1/40. The IBIS didn't even need to work that hard.

Daily drivers are f/2.8 (12-40, 40-150) and supertele (300) is f/4. 1.4x and 2x TCs extend the reach and decimate the light (+1 & +2 stops respectively).

Fastest is f/1.4

Shooting micro 4/3 though so still not as much actual light entering as slower FF lenses.

For me the lens has pretty limited applications but its great at what it does. I use 70-200 f.2.8, 16-35 f.2.8 or 24-105 f.4 for 95% of what I do.

Quoted:
Daily drivers are f/2.8 (12-40, 40-150) and supertele (300) is f/4. 1.4x and 2x TCs extend the reach and decimate the light (+1 & +2 stops respectively).

Fastest is f/1.4

Shooting micro 4/3 though so still not as much actual light entering as slower FF lenses.

You do realize that at the same focal length, not equivalent, actually equal focal lengths, the aperture size admits the same amount of light regardless of the size of the sensor behind it. People tend to flip their shit when I point this out and state that at the same focal length and aperture, depth-of-field is EXACTLY THE SAME.

It only gets different when you try to compare equal field-of-view of the output.
