If you shoot at f1.2 all the time then you have no choice. Faster lenses cost more to build.

The extra lens speed has almost no effect on the image so that aspect is not worth $25. But in really crappy light, even if your need for DoF has you setting f2.8 or 3.5, sometimes the extra lens speed enables the AF to lock on when a slower lens might leave the AF struggling.

For over 90% of users 100% of the time, anything faster than f/2.0 is meaningless. The other 10% really do need f/1.4 and a verrrrry few among those users will sometimes benefit from f/1.2. IOW, even the few who "need" it dont really NEED it.

~~~~~~~~~~~~~~~~~~~~~~~

The existence of f/1.2 lenses is mainly a holdover from classic MF-only (pre-AF) cameras where the slightly brighter view and the reduced DoF enabled humans to focus a bit more accurately. That was true even thiugh they had set f/1.4 or f/2.0 for the actual exposure.

Great response. Thanks for the reality.

f/1.2 is about one third of a stop faster than f/1.4. It depends on whether or not that small a difference is important to you.

How much effort have you really performed in researching this question for yourself? I believe every single EF-mount 50mm prime from Canon is now discontinued. So, you might consider why you'd consider any expired (out of production) DSLR lens at any price.

Moreover, in Jan 2020, I provide multiple visual comparison results of a $140 35 year old 50mm vs the (then current) f/1.2L lens:

Why not?
If I want a 50 I'll get a 50.
Out of production means it's no longer any good?

The Sigma 18-200 I bought years ago is no longer in production, but it's a better lens that the cheaper current 18-200. I'd rather have that out of production model...

f/stops have to do with the size of the aperture, not the quality of the lens.
f/stops are a ratio of the focal length of the lens in mm to the diameter of the aperture in mm. A f/1.2 lens (often written on the lens a 1:1.2) means the maximum aperture for that lens is f/1.2.

Personally, I find f/1.2 rather worthless for these lenses, and essentially anything wider than f/2, for achieving compelling images that balance sharp details with blown-out of focus.

That is: for these legacy DSLR lenses. To paraphrase Rockwell, the new f/1.2L RF version is unbelievably sharp at the focused details at the f/1.2 wide-open aperture, making the EF versions look broken in comparison.

It could mean the equipment can't / won't be fixed. A risk that should be reflected in the purchase price. A risk the shopper should consider when shopping used, or worse, new and discontinued.

Most of my equipment was purchased used, and much of it well after discontinued. It's not much of a 'risk' overall, but certainly a risk where one would / should want to spend the least, understanding the true 'value' of expired equipment in the pricing and amount paid.

The 1.2 lens is a bit sharper at apertures wider than f-2.0. I have both and honestly must say the 1.4 is perfectly fine for the majority of the the work I do. Save the $1000 for something more important.

Some will pay the $1,000 simply because they KNOW it's better.
Might not be able to discern ant differences in all instances, but they know it's better!

Just admiring that front glass assures them of it. Also, its important not let any filter intrude slightly on ones clear admiring gaze upon all that glass.

Ive quite accidentally wound up with a few f1.4 lenses and if you hold one very close to your face that makes the glass appear bigger so you can admire it almost as if its an f/1.2. Try it sometime !

"can't/won't be fixed"???
The older one was better, the newer one was made to cost less.
If they "fixed" the newer one, they'd be making the old one again...........

It wasn't for me, I purchased the ƒ/1.4.

You made no mention of your usage of this lens. Hope the f/1.4 works for you. Canon actually made an f/1.0. One was offered used about 7 years ago for about $3,000.00. Sold immediately. 50mm was the lens included by the manufacturers when one bought a camera back 50 yrs. ago. Still considered by many to be a very useful focal length. The original "Nifty-50" was a really cheap 50mm lens that everyone had for general shooting.

I did, on page one (in case you missed it):

I replied:
Very nicely, but I don't have either the other two to compare. Not really interested in doing so either.
I'm pleased with it. I also like the build more than the ƒ/1.8.

OTOH, some lesser than high end AF systems are confused by the lack of DoF with f1.2 lenses and really work better with slow lenses.

Then why did Nikon make a f0.95 lens if such lenses are just holdovers?
