Any convincing 85 1.2L II vs 85 1.8 comparison pics to buy the L ?

Top left the 1.8, top right the L, bottom left the 1.8, bottom right the L.

Why? Well, both images on the right are sharp and contrasty, while the images on the left are soft, and the detail is somewhat muddled. I am simply assuming the L yields better IQ - if that is not the case, then the f1.8 looks like the real winner between the two!

1.2 1.8 1.8 1.2 respectively (assuming there was no post done to the images), that's my guess.

the images on the left are both from the same lens.

the images on the right are from the other lens.

i made no changes other than copy/paste > Photoshop save to web at highest quality

thanks for playing y'all, i think this will be fun.
especially since i'm the only one that knows the answer.
I'll post which is which tomorrow night.

...

My initial answers (above) stand.

You do realize the moe expensive L focuses much much slower right?

Then we have a guy here on POTN shooting running dogs, rally cars at night with that 85L. And I think he not even using 5dmk3/1dmk4.

But it doesn't make sense - you have 4 images, but there were only 3 originals.

Sorry if i wasn't clear. I took 100 percent crops of the two images taken at 1.8.

The 85L @ 1.2 is not included in the quiz.

For a pro, the build quality difference, the sealing, and the difference in focusing speed might be more than enough to pick the pricey one. f1.2 aperture could be another reason wither because of shallower DOF or better low light performance.
Image quality though is less likely to be the reason to pay the extra money.

AFAIK, the 85L is not weather sealed (as with most other primes that don't don't measure in the X00mm range)

edit to clairify:

the images on the left are both from the same lens.

the images on the right are from the other lens.

which is which, and most importantly, why?

this test will not be timed, but it will count for your end of term grade.

I would assume the images on the left are from 85 1.8 simply because it's softer, as 85L stopped down to f1.8 should be sharper.

I didn't say it was incapable, I said the 1.8 was faster. I have shot running dogs with my 55-250 before getting my 70-200, but I wouldn't say the AF was the same.

Non-scientific comparison. Shot on a tripod, fixed location. Focused on eyes with live view. Used a fixed-location flash. All shots 1/160 at ISO 100.

70-200II @ 2.8 (went for similar framing but landed at 80mm)

I don't see a color difference, at least not on my cheap monitors I'm using right now (at work...).

The biggest difference I see is in the bokeh behind the potted plant and upper background: the 85L 1.2 is exhibiting the non-circular lens "exit pupil" shape (even at f/1.8) while the 85 1.8 is fully round/ovoid.

So for my purposes, unless I needed f/1.2 or the other L-class features (weather sealing etc), I'll be sticking with my 85 f/1.8 thankyouverymuch.

IMHO, YMMV, (duh! - that's the point of this thread!)

I like the way you think.

OK, I know we've been talking shots at 1.8 v/s shots at 1.8, but I still want to channel Nigel from Spinal Tap and say

The number goes to 1.2. Look, right across the board, 1.2...
Oh, I see. And most lenses go up to 1.8?
Exactly.
Does that mean it's faster? Is it any faster?
Well, it's one stop faster, isn't it? It's not 1.8. You see, most blokes, you know, will be shooting at 1.8. You're on 1.8 here, all the way open, all the way open, all the way open, you're on 1.8 on your camera. Where can you go from there? Where?
I don't know.
Nowhere. Exactly. What we do is, if we need that extra push over the cliff, you know what we do?
Put it up to 1.2.
1.2. Exactly. One faster.
Why don't you just make 1.8 faster and make 1.8 be the top number and make that a little faster?
[pause] This goes to 1.2.

Guys is a pro. I wish I remember the name. But the shots are simply awesome. And he has 135L, 300mm f2.8 IS and he picks 85L.

This sounds like a fun project for those owning the 85mm 1.2 and the 85mm 1.8!!
I'll try and get some pics up next week!

Sorry it took me so long. This is actually an old pics. I have not had time to use both lenses on tripod yet, but you can take a look at my dummy model

85mm 1.8 at 1.8

Answer:

you gotta use a mirror to get the answer!



The 85L is on the Left of both crops.

the biggest give away is the vignetting on the 1.8, and the fact that the 1.8 is indeed sharper in those test shots.
