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?

Great comprehensive review as always Richard. Thank you and cheers mate.

Thanks for the comparison of the two lens!

thank you for this vid! helped me to decide between panasonic, oly, and ygnuo

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.

Thank you,Mr Wong .I decide to buy a Yongnuo,it looks get a good balance between price and quality.

Thank you for this amazing comparison review. I just ordered the Yongnuo lens because of your video. Thank you!!!

Thanks for comparing these too.

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!

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

Excellent review of this new and impressive mf/af 25mm. The images are not bad at all. Thank you.

Great review as usual! I wish they made it 1.2 so a bit different. But still looks like a decent lens

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.

excellent review

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.

Really helpful review. Also, love seeing local landmarks in the photos. Kia ora.

Olá, ela funciona na primeira versão da olympus em5?

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.

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!

Merci , attention à la marche !

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.

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

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.

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.

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

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

İs that lens with olympus m10 mark3 (crop2*) good for on desk videos,angle is good for inside ?

Might just give this lens a chance since I don’t own a 25mm 1.7

Is the Yongnuo compatible with the olympus e-pl5 since it's a MFT mount?

it will work with panasonic lumix gx1 camera ?

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.

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.

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 .

wait, this lens not compatible with lumix G7 ???

i wish they make 12 - 40 f1.8 and 75mm f1.8

is it compatible with lumix g7?

A bit strange that Yongnuo created a value lens to replace the only value lens in the system.

¿Alguien tiene el YongNuo en olympus? (EM10 M2?), Somebody have the YongNuo in an Olympus? (EM10 M2)

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...
