What do you guys think about this Yongnuo lens? Are you excited to see another company creating autofocus lenses for Micro Four Thirds camreas? And is there any lens you want Yongnuo to create?
@@TheRealRichardWong There are very few 12mm that are both good, affordable, AND with autofocus. A Yongnuo who could do that would be the "King of the Hill" in MFT!!
Am pretty amazed at the performance and bokeh characteristics that Yongnuo was able to put in this lens. The transitional areas of focus is what caught me off guard.
I bought the yongnou 25mm a few months ago for my son. Recently I put it on my olympus em5 ii, first I was a bit embarrassed because of its plasticy feel and noise. It's very noisey. But it's about results and I have to say the lens delivered. Well worth the money.
Hi! I think the Lumix 25mm is very quiet. In this video, Richard's test shows that the Yongnuo is even quieter. I wonder how Matt feels that it is noisey.@@TheRealRichardWong
@@productguru8323 His lens is defective, it should not make a noise like that, it uses STM motors, but you know its shipped all the way from China, so a lot of things can happen along the way.
RW love your reviews but i prefer Yongnuo 25mm F1.7with focal length with a bright f/1.7 maximum aperture to suit working in a variety of situations. cool i want that lens
I got my Lumix 25 f1.7 as a free promo with GH5 II purchase. As a result I can never complain about cost, but the lens has been very pleasing and I am glad I have it. BTW, while it might have some AF noise, it is way quieter than the 25mm f1.4 Leica, and produces results almost as good as the way more expensive option. The 25/1.7 is an excellent option.
THanks for the review! I saw they have a new m43 camera coming out,can you do a review of that please. i trust your review more than most other reviewers
Great review, as always ;) And an interesting lens for very good price. I'm looking into adding some prime lens into my setup full of zooms, just for "in case of bad light" scenario. That could be the keeper!
Hey Richard, great review and comparison with the lumix. Really thorn between this one and the lumix. It will be used for 4k videos with a panasonic g85... Talking head/pc tutorial type of videos. Can't decide! Could you please help? Thanks in advance
Hello there thanks for the feedback.. can you explain a bit more. In which part of the video are you talking about so I can improve it. Or maybe I made a mistake in the video 😂
Great review, thanks! The Panasonic 25mm f/1.7 had a reputation for noticeable focus shift when stopped down between f/2.0 - f/5.6. I wonder if you have observed that at all, and if so, was that also seen in this lens? I'd love to see Yongnuo bring out a 17mm f/1.7 AF lens. Maybe just an f/2.0, 2.4 or even 2.8 if it would be a little smaller, more affordable and still really sharp. With the right price to performance ratio, I'd buy it without hesitation.
Hey Andrew I can't say I have notice the focus shift but I didn't do any test on that too. Interesting suggestion re 17mm. But there is already an Olympus 17mm. Do you want something that is cheaper? Or better quality?
@@TheRealRichardWong I think the Olympus 17mm f/1.8 is great, but Yongnuo could probably come close enough in terms of optical performance, but by going with the same plastic build as their 25mm, and no features like the focus clutch, they could really cut costs. They could probably easily produce something better than the Olympus 17mm f/2.8, anyway.
Hey Richard, What would you suggest Yongnuo 25mm f1.7 Autofocus lens or TTArtisian 23mm f1.4 fully manual lens. I use g85, use it mostly only for stills and mostly in manual mode. I have 42.5mm Yongnuo af/mf as my only prime lens... And I love it, even though auto focus is problem in it and even after lots of trying manual focus on that lens (or Panasonic 12-60 or 45-150) seems rather tedious and I fear i would miss moments, mostly when I am in family events where lightning is low and AF of Yongnuo suffers. I have heard fully manual lens have better control of focus , but have never tried it.
it's true a real manual focus lens is easier to control, but if you find MF tedious with other lenses, you'll probably find it more or less the same with a lens like the TTArtisan 23mm f/1.4. So i suggest you go for the YN 25 1.7 instead
Hi richard hope you can help me i got gifted an older olympus ep3 with the kit lens but im searching for a cheap wide aperture lens, in yongnuo website the ep3 doesnt appear in the list, do you think that will be a problem or shall i go for a used lumix 20mm or 25mm thanks!
Question is this lens good for recording videos at night like doing vlogs around my city and ghosthunting and exploring abandoned locations.hope to hear from you soon or if you have another lense at this prise range that's better love to hear you opinion
if you want to video yourself (vlogging style), then 25mm maybe a bit too narrow/tight in terms of view angle. the Leica 9mm f/1.7 would be the best for vlogging style video but it's not cheap
Richard, muchas gracias por el video, precisamente voy a comprar mi primer lente de 25mm para mi Olympus OMD EM10 III, y no sabia cual escoger, me voy por el Panasonic que veo que da mas calidad que el Yongnuo, o usted que opina ? Mil gracias
The safer choice is the Panasonic but the Yongnuo is better value for money. You should check if the EM10 III is supported camera on Yongnuo's website to be safe
Yongnuo lenses are interesting, but they decided to use 2 focals where there is a lot of competition (there are already many lenses with 25mm and 45mm focal length). They could build wide lenses : 7mm F/2.8, 8mm F/2.8, 10mm F/2.8 or longer lenses : 90mm F/1.8, 100mm F/4.0 macro, 135mm F/2.0, 300mm F/4.0, 400mm F/5.6...etc. Why ? Because there is not that much competition here, people will buy it. Of course everybody expect the make cheaper lenses than Panasonic & Olympus.
hey Toni, i had a chat with Yongnuo about some lenses i want to see from them. I think they definitely understand there are some lenses like short fast telephoto lenses that a lot of people have requested, but at the same time, it seems the more common focal length are the one that is a bit easier to make so they would like to start with those first. Hopefully that means in the future, we will see some telephoto or wide angle lenses from YongNuo
The list provided by Yongnuo only means those are the cameras they have tested and verified works. As you may notice they only tested the latest cameras (when they release the lens), so there is a good chance it would work with the G7. If any G7 user that has tried this lens, would be great if you can drop a comment here and let us know if it works or not with the G7
great comparison i learned a lot. hmm could you make a review of yongnou vs 7artisans? since native lenses is very expensive nowadays we prefer 3rd pt lenses .
Thanks Richard. At equivalent f3.4, it's not the fastest 50mm equivalent out there. I am not sure if it's worth it, as a used panasonic lens may be a better choice. Great review as always.
Thank you Barry for always sharing your thoughts. M43 is never really the best format if you want fastest (DOF) equivalent lenses. But there are many other advantage like size, weight and price for a brand new lens in this case.
Barry, I think it is important to point out that although DOF and AOV are affected by th MFT crop factor, the f-stop is not affected. A f1.7 is always an f1.7 no matter what sensor size your use. If it were not, we could not have photography.
@@jimeos1 agreed. The amount of light hitting the sensor is less as the sensor is smaller, but the photons per pixel is the same given similar pixel size. As the circle of confusion is smaller, the out of focus area or dof will also be less.
@@jimeos1 agreed. My point was with reference to the Bokeh produced with a ff sensor. When I take a photo at 50mm f2.8, on an apsc, and move the lens to ff at 75mm, and take another picture keeping the same distance etc, the Bokeh / separation is noticeably better on the ff at 75mm, given the interaction of the larger circle of confusion around the bigger sensor. Stopping down the 75mm f2.8 to f4, and it's similar separation to the apsc at 50mm For me, I use faster lenses primarily for better separation and secondary for low light performance
@@TheRealRichardWong yes it probably big and heavy but the market for fast zoom lens is still very open for olympus and pana users, as the one and only lens that many people uses is sigma 18-35 f1.8 for canon + speedbooster. yongnuo will gaining alot of user if they can make one. also the 75mm of olympus is like a unicorn in here. it almost like a unicorn lol. i think there are alot of market they can have by focusing their RnD to developing this 2 lenses
I love the Olympus 75. It was one of the first lens I bought, so sad I sold it when I sold my em5. I think a 75 1.8 would be relatively easier to make and I agree it could be a great seller
Panasonic lenses are so expensive and they even don't have AFC. What a crappy system... man I shouldn't buy a lumix camera. Really disappointed with panasonic. I mean, with new firmwares AF is now acceptable, but most of the lenses are crap. Is there any pancake lens with good CAF, with a good fiedl of view, and nice aperture, for this system, for video vlogging, at all? I mean, we are almost in 2023, rigjt? Auto focus has been around for ages... I don't understand how people enter this system... 25mm is very narrow for vlogging, and these lenses ar very heavy...
What do you guys think about this Yongnuo lens? Are you excited to see another company creating autofocus lenses for Micro Four Thirds camreas? And is there any lens you want Yongnuo to create?
Just bought it recently. Good thing to have a cheaper alternatives. I wish yongnuo could make a 9-18mm or 10-20mm, 75mm 1.8, 100-400mm and 1.2 primes.
I would definitely buy a 12mm with autofocus from them!!!
Thanks Richard, for another excellent video!!!
Why 12mm Thierry?

Great comprehensive review as always Richard. Thank you and cheers mate.
John Glad you enjoyed it
Thanks for the comparison of the two lens!
Great review as usual! I wish they made it 1.2 so a bit different. But still looks like a decent lens
Thank you for watching! oh f/1.2 would be tasty!! Especially not everyone can afford the Olympus Pro 1.2 or the Leica Nocticron
Thanks for comparing these too.
No problem! :)
THanks for the review! I saw they have a new m43 camera coming out,can you do a review of that please. i trust your review more than most other reviewers

Thanks for watching Przyrodnik! Yes a fast prime in the camera bag is always good especially if it's really affordable one
thank you for this vid! helped me to decide between panasonic, oly, and ygnuo
Glad I could help!
Looks like this is a real good and cheap Alternative in 25mm for the MFT System, i would buy this before the Panasonic or the Olympus.
Excellent review of this new and impressive mf/af 25mm. The images are not bad at all. Thank you.
Might just give this lens a chance since I don’t own a 25mm 1.7
Thanks for watching J O S U E! :) If you did get one, let me know what you think about it

I would guess Lumix is better one this case if you use continuous Autofocus because it has the dfd profile
@@TheRealRichardWong thank you for your super fast answer and for the help. I'll go for the panasonic 👌🏻
thanks for the review, but why in video always shows shown two lens names? it is better to write one model of the lens and a photo taken on it.
Hello there thanks for the feedback.. can you explain a bit more. In which part of the video are you talking about so I can improve it. Or maybe I made a mistake in the video 😂
Is the Yongnuo compatible with the olympus e-pl5 since it's a MFT mount?
They have not listed it on their official list, but it doesn't mean it doesn't support it. It could be just they haven't test it
Great review, thanks!

İs that lens with olympus m10 mark3 (crop2*) good for on desk videos,angle is good for inside ?
Depends on the size of your interior, if a small room, it maybe too tight. Something like 15-18mm would be easier
