Yongnuo 25mm F1.7 - Incredible Value AF Micro Four Thirds Lens 

I am not sure what happened to the pricing at some parts of the world. but here in Malaysia, Panasonic 25mm F1.7 is about RM1000/USD250, you can get about RM750/USD190 at bargain. The Yongnuo 25mm F1.7 I purchased at RM385/USD90. It is practically HALF the asking price of Panasonic 25mm F1.7. The only reason the Panasonic lens is selling so low in some parts of the world is due to poor sales strategy and promotion control implementation over the years that eroded the value of the lens in the market. While this is good for customers for spending less, it is hurting the manufacturer for earning less. At least Panasonic maintains their pricing reasonably well here in Malaysia. RM750/USD190 for 25mm F1.7 is still a fantastic price.

Your images pleased me, Robin. Thank you.

Great to see some budget lenses get a fair review. It may not be for everyone but it's going to be great for some. Keep up the great work. Thank you!

Thanks Robin, and may I say, you are looking very fit and well. Always a joy to see your smiling face. The lens looks great. I have an Olympus 17mm, that I love, but seeing your marvellous street shots, I'm very tempted to get a little closer. Take care.

Great review, thank you Robin.

Nice lens! Thanks so much Robin!

Decently priced and promising offering for MFT shooters on a budget - thanks for the review Robin

Thank you very much Robin, excellent review.

Wow, that is a well performing lens with few easily corrected flaws. Now surely is a great time to start out as a photographer on a budget. I wish shooting with fast primes was that affordable when I started out :) Also: any plans for "Let's do this!" merch?

Thank you very much, Robin... 👌👍👍🙏

Thanks for the review. Looks like a nifty little lens for the price. Next time I have some extra money, I might pick one up. I have three lenses for my Olympus OM-D, they're all Olympus zooms, a 14-42mm, a 40-150mm and a 70-300mm. Don't currently have a prime 25mm. Since I've been pretty low on capital lately, this might be a suitable option.

Great Information Robin! Thank You!

Yongnuo 25mm F1.7eith focal length with a bright f/1.7 maximum aperture to suit working in a variety of situations. cool i want that lens

@7:30 Hey Robin, nice Robin! 😂 Great vid! Good bargain lens, it sounds like! Would love to learn more about lesser known brands of lenses like this for the MFT format.

Great in-depth review!

I have a an DJI Inspire 2 with the Zenmuse X5S which is a M43 camera. The lens is a F1.7/15 and it works great on my M1X.

Great honest review. I picked up the Yongnuo 42.5 f.7 (2nd edition - Rob Trek hated the first edition!) and was pretty happy with it. I was thinking about the 25mm and you have talked me into it! Not stellar, buy good enough for holidays, where I don't want to risk the more expensive kit, I have. Thanks for the honest and thorough review.

Great review, Robin. Nice to see you out and about! Hope they produce a few wide- angle lenses. Cheers, Dave from Scotland.

Nice review.For imaging quality, how it compares TTArtian 35mm f1.4? I hoped for this comparison

Thanks for sharing, bro. Looks like an awesome lens for a little money.

Skinny Latte on way - respect from UK.

Love the black birds photo @ 4min 13 sec !

I'm no pro photographer but I really like the image quality from this Yonguo lens - at f4 and 5.6 the quality is excellent - and for the price (I paid £98 from Amazon UK) it is an absolute bargain.

Looking at a reputable store, in Canada the Yongnuo can be found for around $145CAD (1:0.77 USD) and the Panasonic around $200CAD as of writing. I think the $55 difference for a new M4/3 user could be justified here. Get a step up ring to say 67mm, get a nice polarizer, ND filter, simple lens hood, and you're set to shoot a lot of interesting subjects and compositions than just a lens alone. Not to discount the Panasonic, I own one and I love it dearly when I get a chance to use it. A very nice lens on the budget side of things. I am personally surprised how well the flare was controlled on the Yongnuo lens!

Thanks Robin, great review we can’t all afford Pro lenses

Thanks Robin you sold this one im on a tight budget so I must have it ill have to get you a coffee 😅

Hi Robin, thanks for reviewing the Yongnuo prime lens 25 mm f1.7. It would have been helpful to compare the lens with established lenses from both Olympus and Panasonic. Not only the price, but also dimensions and weight would have been interesting. The Yongnuo lens presented seems to be a monster in terms of size - compared to the M. Zuiko 17 mm f1.8 or the Lumix 25 mm f1.7. The price in Amazon Gemany is 125 € (March 7th, 2023).

Terimakasih pak Robin

Crazy how affordable these third party AF lenses are becoming!!

Good day sir! I've been a fan of your work :D I'd like to ask if this lens works well with the first EM5 as well? Their website says that this is only compatible to the em5 mark 2 up. Thanks!

Thanks a Lot for the review dear Robin! And allow me suggest the Sigma 56mm F1,4 for another video, i have heard many good things about this lens, but i would very appreciate to hear your thoughts about this Lens. Se you!

Thank you so much Robin! I love your every videos. They are educational and down to earth, unlike those pro "reviewers". And I'm wondering if you tried 20mm 1.7 lens and maybe will you do review of this lens someday? It's right in between 35mm and 50mm focal length so for me it's very versatile and not to mention pancake size and 1.7 aperture. Thank you sir and I wish you the best Robin! Regards Ari

Hello. Thanks for the video. Have you heard about the problem with stabilization of this lens with some Olympus models? One person wrote that the matrix stabilizer with the Yongnuo 25mm F1.7 does not work on the Olympus PEN E-PL9 camera. There are no problems with other lenses. Does the stabilizer work on your Olympus? Have you checked?

Nice review, Robin. Keep safe!

Thank you for the review. I don't think it is the first budget lens; I bought the Panasonic 25mm f/1.7 when it came out for $99. Also, I just can't imagine why anyone would prefer this lens over the Panasonic. It will not have as a good a resale value. Also, what about in camera software corrections that communicate with the lens? I would have appreciated side by side shots under the same conditions. Tx.

I was one of the people who requested this so thank you Robin. I have the Olympus 25mm f1.8 so I don't need this lens, but I am always curious to know how good or how bad very cheap lenses are. I was impressed that it has a metal mount which is surprising for the price. I think for a lens that you will use a lot it's worth spending more for a better lens if you can afford it, but budget lenses are good for occasional use or trying something new. For example I would like to try out a fisheye but wouldn't want to buy a very expensive Olympus, so am looking at the 7artisans and TTartisans lenses.

Hi Robin thanks as always for the video. Any chance I can ask you a question off topic? Could do with a voice of experience with Olympus.

That must be the lens you used in the low light video which I asked about. I really like the look of that at the start of your video. The bokeh in the background was special enough I asked which lens you were using. I was impressed enough to watch that opening a few times trying to figure out where that look came from. Definitely a nicer and cleaner oof rendering than the Pany 25/1.7 I got as a light weight inexpensive throw in pocket and have with me lens.

Good review; I might consider it if I'm looking for a 25mm.

Great review! Thank you! Glad that you could go out to shoot :)

Speaking of remarkable value, I recently picked up a Samyang 35mm F2.8 FE pancake lens for $150 for my Sony. Fantastic little lens for street shooting, sharp even wide open (unusual for cheap lenses), and has minimal distortion. Coupled to the A7C, the overall form factor is downright diminutive, and much like the older style Rangefinder cameras. Samyang is pretty hit and miss on lens quality, as they have some really excellent value lenses, but also some not-so-great lenses. For well-established mounts, there’s generally some really nice value lenses to be had if you’re willing to do your homework. 😉

Great outdoor video waiting your next review 8-25mm 😅

This lens looks great value for money. Since I have a Panasonic/Lumix Noctricron 42.5mm with f1.2 I do not need to purchase. If anyone wishes to take photos in low light then this lens is fine. Super for indoor without a flash or in caves etc.

Ok so what micro 4/3lens you recommend at this prise point that has automatic focus and manual with better quality image specially for video filming like RU-vid .hope to hear from you soon.

Olá, ela funciona na primeira versão da olympus em5?

hola buena noche queria saber si ese lente es copatible con una canon 5d mark iv muchas gracias

Looks similar with the panasonic 25mm f1.7, except the less intense chromatic abberation on the panasonic. In my country panasonic is on sale for about 150 USD

Auto focus?! My motherland rocks!!!!!!!!!!!!!!!!!

how good is the lumix 20mm f1.7 sir robin

Has anyone used this lense on the EM10 mark II? Amazon says it’s not compatible (it is but starting on the Mark III)

Just wondering, is this lens compatible with Olympus EP3?

How does it compare to the Lumix 25mm f1.7

What about tracking, is it good?

I have to spend my money on other things - both my EM-1 and EM10 Mark III have broken in the last 24 hours. Do I invest in another EM camera having already lost hundreds of ££££ or take the opportunity to move to full frame?

can i have the link you used to get your lens please ?

Good review, the lens has quite a few problems that can be corrected in post. No thanks, better to save up for a better lens.

Abang robin ... Ni bole masok dekat gf9 kn.. 25mm 35mm 42mm 50mm mana lg elok bang

Can use on Canon 600D?

Can anyone confirm if this lens works on an Olympus EPL-1 ? I read somewhere that the camera won't talk to the lens....looking to verify that.

good review I bought the 30mm Samsung for a prime. It still saved a bundle over the 25mm 1.2 This would have been ok.

What do you say about AF in video?

Works on lumix g7?

I guess it can fit the same to em-10 mark II? I already have olympus 25mm f/1.8

hi anyone planning to buy this lens is this compatible with em10 mark 1?

Got rid of my Lumix 25mm because of "focus breathing" - the focus changes with the f-stops. Hope this is better.

Is it obvious how to fix the distortions you talk about with this lense in post-processing. Can it be done in Olympus workspace? I have never done post processing in any serious way.

👍

Why would I go for this over a used Olympus or Panasonic for the same price?

Hi Robin do you know if they will have a 7mm or 10mm

Nice review. I will get 1.

Plenty of photographers prefer to just shoot JPGs and skip all the post processing. And I suspect most "beginners" do. Yeah, you can get the best photos by editing them on a computer with good software, but not everyone likes the process.

I would pick the Panasonic 25mm f1.7 or the Oly f1.8. Resale price of a yongnuo is 0 while the other two keep their value intact. Looks cheap but it isn’t IMHO.

I ordered one for my old E-P1 and it turned out they don´t work together, no matter what I try! The display turns black when I mount the lens and the camera becomes unresponsive. The lens works just fine on a Panasonic GH2 and the E-P1 works with any other lens I put on it, so it must be a compatibility issue. In other words, I just wasted 100 bucks.

Well, I have Panasonic 25mm F1,7. Is ” Your ” lens bettet?

This lens does not work on my blackmagic 4K camera

Lumix at $147.99 seems like a better deal. In the past, Lumix was under $100, but perhaps never again, who knows. Really, $115 for a brand X compared to buying a Panasonic for just a few bucks more makes a whole lot more sense to me.

This is really a comment in response to the poor C-AF performance you saw using this lens to make your latest video [ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eB-C1Mh8v4g.html ] , but I thought it made more sense to add it here (hope that's OK). So, regarding the Yongnuo's autofocus issues in video on your E-M1 MkII: I was looking at the product compatibility matrix for this lens on Yongnuo's site to see if my little old E-M10 MkII was listed, and it isn't, only the Mk III and IV are. However, amazingly, NONE of the E-M1 marks are listed at all, so that might possibly explain why you're seeing it lose you sometimes in C-AF. In fact, Yongnuo only list the following cameras in a compatibility matrix on their website: Olympus: E-M5 MkII, E-M5 MkIII, E-M10 MkIII, E-M10 MkIV, PEN-F, E-PL9, E-PL10 (7 models in total) Panasonic: G100, GH5, G9, G95, G85, GX9, GX85, GF-10, GF-9 (9 models in total) I was surprised to see such a short list. By "compatible", I assume they mean "full" compatibility (you would at least expect acceptably good C-AF, even with tracking), but I guess that single AF works fine on many more bodies than they list on their site. It's probably also more of a budget issue: Yongnuo can't test their lens on every single MFT body out there, especially considering the huge array of advanced features (in-camera focus stacking, Starry AF, etc, etc). However, that means we are doing the product compatibility testing for them, and I don't particularly like the idea of that, despite the low, low price. Of course, as you have noted yourself before, just because there's a common MFT mount, that doesn't mean that you will get the best performance from a Panasonic lens on your Olympus body or vice-versa, so I suppose that with a third-party lens, some issues can be expected. As long as they are fairly minor, they may not be a deal-breaker.

surprised a 25mm has THAT strong barrel distortion?

What's this ??You are ..gasp..OUTSIDE!!

To me, the build quality seem not cheaper than the 25mm F1.7 from Panasonic.

I’ve got the Panasonic but if this had been available at the time I might have saved a bit of money and gone for this instead!

Not much of a difference here in the UK in price between this lens and the Panasonic 25mm f/1.7. The cheapest, I can find the Yongnuo without importing it myself (and paying duty) is £128. The Panasonic will cost you £148 and you will get it from a shop with guarantee etc.

I honestly don't think these lenses are a great value when you consider that in the used market the first party equivalents go for similar prices to these new and are smaller, lighter, and have more features.
