VILTROX 28mm f4.5 Pancake Lens Fuji x, AF 28mm f4.5 X Mount Lens for Fujifilm, Fixed Aperture F4.5 Fuji x Mount for Fujifilm X-T5 X-H2 X-T50 X-M5 X-T30 II X-Pro3 X-S20 X-E4

As most of you probably already know, this is a fun little lens. It's barely larger than a body cap, has the slick integrated lens cover, and manages to squeeze autofocus into that tiny package. Sharpness is remarkably consistent from corner to corner in my chart tests - as sharp or sharper than any other pancake out there with the possible exception of the Fujifilm XF 27 or Voigtlander options. It doesn't quite have the microcontrast and color quality as those competitors but it's no slouch, and for the price I have zero complaints. I wasn't expecting this level of clarity for under 100 bucks. The fixed f/4.5 aperture doesn't bother me either. One of my other favorite street lenses is the AstrHori 14mm f/4.5. I think that aperture strikes a great balance between functionality in most light and good sharpness with just a little character across the DOF. It isn't a low light monster or anything, so temper your expectations in low light and expect to crank your ISO. On the downside there is no manual focus option, so trying to milk what little bokeh/defocus you can out of the lens can be tricky, as you have to use single point AF and nail your spot. Also there are no filter threads so you can't use any ND filters in bright light, or a CPL or anything, which is something that I find very useful on the AstrHori f/4.5 lens. Next, the AF isn't the greatest. Even in good light and with static subjects the AF hunts a bit and may take a couple tries to lock, especially if there's not good contrast in your focus area. Forget about any complex focus tracking, or even using basic AF-C in most cases. Again, not surprising given the price point. Just be realistic with your focusing expectations and you'll be ok. Lastly, the MFD and close-up focusing aren't great so don't expect to get right up on your subject with this lens. It needs a little more room to breathe than you might expect. All in all it's a great street lens, and it's totally pocketable on smaller bodies like an X-A, X-E or X-Tx0 series. Definitely a screaming bargain, despite its flaws.

While I think it's great, I returned it. It's so small it can work like a lens cap. The image quality with full light is pretty good, but when it gets even a bit darker everything struggles. I think it's fun to use, just not for me.

So compact, perfect for travel. The focus is good. The lens is so light that it makes the camera fun to take everywhere. Definitely good price for a good lens.

Got this lens for $79 during sale. I think I will keep it since it's so cheap. But not sure I would for the full price. After using it on my X-T3 for about month, here are my thoughts on it: Pros: 1. Really small pancake lens. It reminds me of the Pentax DA 40mm lens and the Olympus body cap lens. 2. The 43mm full frame equivalent makes this a normal lens good for street and general shooting. 3. Cheap enough that I can be quite carefree with the lens. 4. Interesting aesthetics. Check out Dustin Abbot's review of this published in Feb. 2025. I think he described it really well.. Cons: 1. AF accuracy. This doesn't focus fast, but that doesn't bother me. But the focus accuracy or softness for long distance focusing bothers me a bit. So, this limits the lens more for shooting things within a shouting distance. Landscape use is no good. 2. Focus speed. While it doesn't bother me much, it's still not very quick. 3. Image softness. This is a full frame lens, but even on the APS-C sensor, I notice that the edges are soft. This is not a sharp lens. So, that's something to keep in mind. 4. f/4.5 -- I think a lot of people might not like this. It certainly would've been better if this was a f/3.5 or even f/4 lens. But I'm ok with the f/4.5 fixed aperature. This is a fun and really small lens that's also inexpensive. For the price, I think it's worth it. Just need to keep the limitations and quirkiness in mind. If Viltrox can make something like the Pentax DA40mm which was a f/2.8 lens that was also pretty sharp, it would be awesome. But for $79, this is not bad and it's fun enough.

The VILTROX 28mm pancake lens surprised me. The biggest win is just how compact it is while still having autofocus. It’s super thin/small, which makes for an awesome travel lens when you don’t want to carry anything bulky. The autofocus itself is quick and reliable, and for the price the image quality is better than I expected. It’s not going to match high-end glass, but for what it costs and the size you’re getting, it holds up really well. I found it to be a great lightweight option for walking around or throwing in a bag without thinking twice. The part I didn’t love was the locked aperture. I get it’s a pancake lens so there are limits, but still, it would’ve been nice to have some flexibility there. Also the lens cap design is both clever and a little frustrating. I liked that it’s built in so you don’t have to worry about losing it, but I had it flip open or shut a few times when I was sliding the camera in and out of a bag. Overall though, I’d still say this lens is worth it if you want something small, light, and easy to carry around with decent performance. It’s so small I’d say it is a way to have a functional/useful body cap!

Love all my other Viltrox lenses, but this one was just bad. I don’t know if it was a dud or all of them are like that, but my copy was very soft in all conditions. Also made my camera (X-T5) freeze up a couple of times. Had to return it.

Obviously this isn't going to be the sharpest lens you buy. The size, weight, and character you get with this lens make it extremely portable and provide a very nice feel to your images. I think if you're looking for a fun travel lens or a good street photo lens, this is an easy buy at less than $100. I really enjoy the look and I think is makes for a good casual portrait lens as well.

Excellent little $90 lens. And when I say little I mean it! This thing is teeny. Its auto focus tries really hard. Weighs next to nothing.

Ich fotografiere mit XT-4 und XT-20 und habe für letztere ein schmales, günstiges Pancake als "Immer-drauf" gesucht. Zuerst habe ich mit dem TT Artisan f2,8 27mm geliebäugelt. Lichtstärker, mit Blendenverstellung und vermutlich optisch besser. Aber das ist leider doch um einiges dicker (und schwerer) - nicht wirklich Westentaschen-geeignet. Und teurer aber das wäre in diesem Preisbereich für mich vernachlässigbar. Das Viltrox ragt kaum über den Handgriff meiner XT-4 und der XT-20 (mit Meike Grip) hinaus. Mit der XT-20 passt die Kombi wirklich in die Jackentasche. Mit dem eingebauten Objektivverschluss spart man sich dazu die Fummelei mit einem Deckel. Und ja, die feste Blende schränkt ein, unterstreicht aber den gewünschten Point-and shoot-Charakter. Dafür dass man immer mit Offenblende arbeitet sind die Ergebnisse nicht schlecht. Mit etwas Nachbearbeitung lassen sich wirklich gute Ergebnisse erzielen. Die Beispielbilder sind RAF-Aufnahmen die in Adobe Camera-Raw (CR) zu jpgs konvertiert wurden. Teils Out of the Box und zum Vergleich mit dem in CR hinterlegten Objektivprofil sowie dezent geschärft. Ansonsten ohne Korrektur. Man sieht, dass bei direktem Gegenlicht Flare ein Thema ist aber einigermaßen beherrschbar bleibt. Dazu kommt ein klassischer natürlicher Bildeindruck entsprechend 42mm Kleinbild. Ich werde es behalten. 4,5 Sterne aufgerundet ;-)

おそらく、F値を4.5に固定する縛りを設けることで 薄さと、納得できる写りを実現した一品だと思います。 レンズキャップが割につけて、それでいて 撮影する絵も満足いく品質で撮れるので 満足しています

It doesn’t work. It looks blurry all the time, the camera doesn’t shoot. I tried multiple times and it’s a no go. Don’t buy it!!!!

So amazed how well this lens works and how it looks on my Fuji xs10. It’s pretty much an all round lens, so perfect for everyday use and also when on vacation with the camera weight being much lighter. Very happy overall

Nos 1, pour le prix c'est parfait
