Sigma 85 1.4 DG DN ART (vs Lumix 85 1.8)

Nice Work Richard

Great video! I think I might have to pick up the Lumix 85.

Thanks for the comparison video. I'm very tempted to go full frame with the S5. I'd personally go with the Lumix 85mm. Reason being they're likely going to make the 35mm and 50mm very similar in weight, and most likely will be having the same filter thread across the lenses. Meaning you'll have an easier time with gimbal work with these primes. And these lenses are more adept with the current Lumix dfd autofocusing system for video work.

I would pick the sigma because of faster aperture and nicer bokeh. But The lumix is not bad at all.

Thank you for the video. The lack of AFC for the sigma lenses on lumix bodies is one of the reasons I switched to sony. I just received the sigma 85 for sony and I can say that the autofocus is very good so far. The S1 could be the perfect camera for me if they "really" improved their AFC and take the L mount alliance seriously. It feels like Panasonic doesn't want sigma to sell lenses for L mount.

You've helped to turn me into a Panasonic guy. My s1h arrived this week and my s1r arrives next week. Loving the big bodies. I've fully embraced manual focus for video.

Thanks for the review, I don’t know why I get so happy when you upload dood.
Probably because you are a S-Series warrior who runs around in his backyard.😆

You inspire me to keep creating on my channel, 🙏 thank you.

Always glad to see you and watch your videos. I just pre ordered a lumix 85 f1.8, thought it may have better af capability 😂

Really great video, I have the Sigma you test with the S1 And my experience with it is 100% what you describe.
I didn't test the Panasonic 85mm but from what I see I would say to people who wonder which one to buy: if you can wait for the Panasonic do it, its lighter cheaper and I don't see a much difference in quality with the Sigma. But if you can't wait, the sigma is a really great quality lens even if I wouldn't advise it for video.

👍🏻

Thanks for another fair and informative review! I would pick the Sigma because it gives best portrait photos results. Autofocus in photo mode is great too

What, exactly, makes a lens qualify as an "art" lens?

Thanks for the comprehensive and fair review. I would pick the sigma because of the build quality and bokeh!

Such a cool lens! 1.4 is super bright 😯Great review 👌

I just found your channel and I think your videos are awesome because they are very chill and relaxing not as "hyped" as a lot of the other channels.
Thank you for the content!

your static autofocus hunting is a tiny bit flawed.

the camera HAS to move the element. it doesnt know when something is "in focus" it just knows when peak contrast has been achieved. it needs to know what out of focus looks like before it knows what "in focus" looks like.

Now that the camera has to wiggle the elements a little bit, the f/1.4 is going to look like it "hunts" more, because its f/1.4. going out of focus will create more blur than the f/1.8 will. and it will be slower because f/1.4 needs to gear down the motor more, because it needs to be more precise. being off by a little with f/1.4 is far more unforgiving than f/1.8.

this will almost ALWAYS be the case, since the lens mount limits how much power you can deliver to the motor. The only real way to improve it is to use lighter focusing elements (less glass, likely impacting image quality), or more efficient motors (cost will rise exponentially)

I am disappointed this lens doesn't AF that well. I got the S5 in hand, and evaluating whether to return it and wait for Sony a7iv next year. The lack of a great lens selection at cheap prices is a big issue for me.

Nice comparison, but you've overlooked pretty big distortion of Sigma. I think it is caused by automatic correction switched to On in camera. (May be it is the cause of the difference in FoV.)

Nice video Sir Richard! i Wish this Sigma had the ND filter box like my 14-24, but that aperture dial on this 85 is amazing! Probably gonna get it soon!

Lumix cams so terrible man 🤦🏻‍♂️💩 dont like it 🤷🏻‍♂️

The Panasonic lens, is far better value for money, The sigma offers less than 1 stop more light, but costs nearly twice as much.

Hi Richard, great review as always, I just purchased the Sigma as per your review and suggestion, I can't believe how sharp it is even at f1.4, I don't mean is sharp like everyone says is sharp, I mean sharp like nothing I have seen before, I had the Sony 85GM, and is nowhere as sharp as the Sigma, the Bokeh is very dreamy-like my Leica Noct 1.0, but super sharp on the focus area, however, truth be told, it is so hard to nail focus on the Noct, maybe 1 out of 10 is in focus.

How about a short review on the S1r version 1.7 firmware, like to get your take on the supposed improvement on AF. Thank you again for taking the time to do these great videos.

Great video thank you! 
I think i'll buy the lumix ... the sigma is better(i like it), but it costs so much more than the Lumix and the difference is too small ... i can put the money into another lens. when panasonic brings the 50mm 1.8 on the market (and the price is similar) maybe i have two good lenses for the price like the sigma

Great review - thanks. Bought an a S5 for video and I think the Lumix 85mm is best for me based on your autofocus test and your focus sample helped a lot.

The Panny will work on a Leica SL right?

Great review Richard, just what I was looking for, thank you

Thanks man. Great video. Plenty of useful info. I just bought the sigma and it's being delivered tomorrow. And now I have a good idea of what to expect. Bravo 👏

I happen to see that you take pictures by just touching the screen on lumix S5 .. how is that possible? Can you reply me or make a short video on it ..thabks man

good compare, Sigma is so much sharper. I cannot decide if its 500€ better than the Lumix. With which cam did you take those night photos?

Sigma looks much better in this video, maybe its got to do with settings and post but i assume not

Can you recommend 85mm for video?

so frustrating how on a lumix body the sigmas have like 0 af..

Sorry but Your shirt is really distracting viewer from the content with it fake chromatic

How does the Sigma perform on your S5 II with phase detect AF?

When we are looking at 1.4 v 1.8 the real benefit here is low light astro stuff for a 1.4 as the dof at this range is so easily replicated with the 1.8 and a tiny bit of post work

You wouldn’t happen to have made a similar video for the 24mm would you? (Sigma 24mm 1.4 vs panasonic 24mm 1.8)

I use sigma 85 1.4 dg dn with a9 sony very fast focus even better than 85 1.8 sony
maybe different system depend on camera

As always, very nice 360 degrees review Richard. I really enjoy your channel!

Sharpness comparison at higher f stops plzzz

Nice review! I don’t like either lens but this was super helpful!

Does this lens have a stair-step aperture or a smooth ramping aperture? I noticed that the Sigma 24mm DG DN lens on L mount DOES star-step. The same lens on Sony is NOT crippled. So,...it seems that Lumix is playing games on some Sigma lenses. If you are on a gimbal and want the S1H or S5-IIX to run auto aperture,...you will get exposure "jolts" as the aperture lens in each 1/3 stop step. I literally returned this 24mm immediately because of this. Do you know if they crippled the Sugma 85 aperture or is it smooth ramping? (FYI,...Lumix branded lens do NOT have a crippled star-step ramping aperture)

Thanks for a great comparison. You’ve helped me make a choice. 👍

A comparison from you of the Lumix s pro 24 70 vs the Sigma 24 70 would be nice, since almost no one addresses comparisons as detailed as yours,I saw one that is in German, I don't understand anything it says but at least it tests vignetting, flare, focus distortion and construction quality, but a comparison like the one would be good. yours on the s5ii and if it is really worth paying the extra for the Lumix s pro since both lenses are still widely used today and there are almost no comparisons with the new AF system.

I recently became interested in this Sigma lens. When I saw you had a review on it, your video was the first one I clicked on! Always love your reviews! However, can you re-test the auto-focus of this Sigma lens with the new S5 II/IIx?

L reviews

What do you think about the Sigma 85mm f/1.4 DG DN ART lens? Would you choose it or the Lumix S 85 1.8 instead?
