Sigma 18-50mm f/2.8 DC DN Contemporary Ideal for a wide range of photo and video applications including landscapes, portraits, street photography, architecture, and events, the 18-50mm f/2.8 DC DN Contemporary Lens from Sigma is a small, light, and bright standard zoom for crop-sensor mirrorless cameras. Offered here with a Leica L-mount, this lens provides a versatile full-frame equivalent zoom range of 27-75mm and a wide constant aperture of f/2.8 throughout the entire zoom range. The lens design includes three high-precision glass-molded aspherical elements coupled with a special low dispersion element. Together they minimize the total number of elements for superb optical quality without excessive weight. Autofocus is exceptionally fast and quiet thanks to the lens's stepping motor, which can be particularly useful when shooting video or fast-moving subjects such as children and animals. An ultimate workhorse, the lens features a minimum focusing distance of just 4.8", enabling it to be used for macro-style close-up photography, and the lens is also outfitted with a rounded seven-blade diaphragm for a pleasing bokeh quality.

A Personal Game Changer

originally posted on bhphotovideo.com

About a year ago I purchased the Fujifilm XE-4, and it came as the kit with the 27mm pancake lens. The idea was that I would have a portable system that was fun to use whenever I was traveling, and did not want to bring out my giant Canon system with all of the interchangeable lenses. At first I absolutely loved the setup and thought I would never grow tired of having the 27mm married to the x-mount, but after about 6 months of shooting, I did. Personally, I have always been someone that has gravitated toward the usefulness/freedom of a zoom lens, and I started shopping around, but didn't want to spend a fortune since the Fuji setup is not my main system.

This lens allows me to be much more creative with my images, and I find myself picking up the XE-4 much more often now (as I've only had the lens for about one month). I play around quite a bit with the film simulations from Fuji, and this lens complements the image quality SOOC very well. I am so happy with Sigma and this purchase, and that is ultimately what it's all about--going out and shooting more images with a system you love. I would definitely recommend this lens be in your kit.

Disappointing for Fuji, Sony version looks good though

I bought this lens for my Fuji X-T4 and really wanted to like it. The lens had lots of positive reviews from other mounts and I was excited to have a small zoom lens that offered great sharpness.Unfortunately, it was a disappointment, especially at 18mm where the corners were weak, even at f8 and f11. At 22-50mm the corners are all right, but I couldn't get over the 18mm corners. Another reviewer had the same weak corners at 18mm for the Fuji mount. What is a letdown is that the Sony mount Sigma lens seems to have pretty good corners at 18mm.

This is basically the APS-C equivalent of the 24-70mm 2.8, virtually a legendary workhorse for any photographer. I shoot stills and video on an a6500. My most basic requirements for my kit for decades (going back to when I only shot film) has been a zoom with a wide range and also a fast normal lens. Maybe add a dedicated portrait lens and an ultra wide. I have the Sony 18-135mm, and Sigma's trio which is just such a well planned set of primes (except for the varying filter threads!!), plus a Samyang 12mm. I rented Tamron's 17-70mm and it's fantastic, but for my work, it was just bigger and heavier than what I wanted. This Sigma fits the bill perfect for splitting the difference between my fast primes and my convenient super zoom.

This Sigma fits the bill perfect for splitting the difference between my fast primes and my convenient super zoom. I loose some speed and some reach, but gain loads of convenience while retaining the amazingly small size. This zoom may be redundant in a few ways, but still the best of both worlds when I want/need it. Full frame guys (I shoot that too) may complain about slightly deeper depth of field and minor lowlight differences of the sensor, but this lens with a fitting camera is very close to a frame professional 24-70mm set-up at a fraction of the size. As for the extra 20mm you gain from the Tamron, I'm okay with a small crop if I need it and I can live with the 1mm less on the wide end. I would have loved the stabilization, but at least I have IBIS, even if not quite as good. I hope this review helps a few people looking at the same decisions as me as I was sizing up the 17-70, Sigma's trio, and this lens (the Sony 16-55 is just too rich for my blood).

Great Lens!
5 July 2022

Having joined the E-mount APSC ecosystem I've been waiting for years for any company to make a compact relatively affordable standard zoom lens. Been rocking the a6xxx line since I started photography and never saw the point of having a convenient compact camera with an oversized lens attached to it (seems to defeat the purpose). I dont print or do professional work and all my images are viewed on screens of various platforms so the sony 16-50 kit lens and collection of sharper primes has served me well. Now comes sigma with a compact, sharp, f 2.8 lens. The image quality is great and even with APSC sensor you can still crop a good amount with good image quality. F2.8 is also good enough to have great bokeh in your images. Most importantly its reasonably sized for ... MoreHaving joined the E-mount APSC ecosystem I've been waiting for years for any company to make a compact relatively affordable standard zoom lens.

The only negatives would be the fact that it does not have stabilization and there is occasional chromatic aberration depending on angle/light. But for the price and size those are reasonable compromises. So if you're in market for appropriate sized lens for APSC camera thats sharp in the standard zoom lens definitely recommend!

Leave the fujicrons at home
27 December 2022

I've been looking forward to this lens ever since I got my X-H2 and returned my 16-55 f/2.8 for being too dang big. Side by side with my XC 35, it's ever so slightly less sharp at any aperture, literally only 1 or 2%, and that's the weak point in the range, I think it's sharper than the 23mm f/2 (although I no longer own a copy for comparison). Close focus is incredible, focus speed and 'feel' is decidedly more modern than the Fujicrons (I think Sigma has been learning some lessons working with Sony). Build feels very sturdy, Sigma advertises it as only being sealed at the mount but I wouldn't be surprised if there's more gaskets in there.For less than the price (and weight, and size!) of two Fujicrons, you get pretty much all of them in one lens, minus a stop of ... MoreI've been looking forward to this lens ever since I got my X-H2 and returned my 16-55 f/2.8 for being too dang big.

To me, that's an easy trade.One final word, the color reproduction of it is true to the usual Fuji tones, which was a selling point for me. Next to my other Fuji lenses, I get the exact same color profile and white balance for a given scene, which isn't the case for most of my 3rd party and adapted lenses.

Nice Match for the XS-10
26 June 2023

I bought this lens as a possible replacement for the XF 16-80, which I find too cumbersome on the XS-10. It was a choice of the Sigma or the XF 18-55. The lack of an aperture ring on the Sigma gave me pause but catching it on sale and B&H's return policy made the decision easier.I'm really enjoying this lens. It's obviously smaller and lighter than the XF 16-80 and for me, just fits the XS-10 better. The build quality is fine and the lack of an aperture ring has not been an issue. The picture quality is on par with the XF 16-80 if not a little better. Having a constant aperture is also a nice feature. The real kicker for me is the close focusing distance. I'm having a blast using this lens up close.The Sigma 18-50 is a keeper for me.

Perfect for travel
3 May 2022

At $580 this was the most expensive lens I've ever purchased, but I don't regret it at all. This really feels like a near perfect match for my Sony A6500. The build quality is great. Its light and small, almost the same size as my Sigma 30mm f/1.4. The focal range of 18mm - 50mm on Sony APSC is roughly equivalent to 28mm - 75mm on full frame, which is really solid for a single-lens photography kit. While I do wish that it could have extended to 55mm on the far end (85mm equiv.), the 50mm is just enough reach to get some nice convenient portraits and up-close macro shots, along with filling the frame with some slightly more distant subjects. On the other hand, the 18mm (28mm equiv.) is really perfect for those large nearby subjects, buildings, etc..Overall I am ... MoreAt $580 this was the most expensive lens I've ever purchased, but I don't regret it at all.

I used to shoot primes almost exclusively, especially the Sigma 30mm f/1.4 and 56mm f/1.4, but thanks to this lens I can safely leave all my primes at home.

Surprisingly compact lens with excellent image quality
27 June 2022

My first impression of this lens in a store was that it was too small and didn't feel like a serious lens. I still put it on my a6600 and took a few shots and then compared it to the Sony 16-55 which felt more substantial with a price to match. When I looked at the raw files at home I noticed that there wasn't really a resolution difference and the Sony files had heavy distortion and vignetting before a profile was applied.I decided to get the Sigma knowing I could resell it if needed. Well, I tested it against my old Sigma 17-50mm f2.8 (EOS) which was my main zoom and then also the excellent Sony 55mm 1.8 and Sony Zeiss 24mm 1.8.Moving away from the retrofocal design for DSLRs meant there was no optical compromise- on the wide end the Sigma is far more detailed ... MoreMy first impression of this lens in a store was that it was too small and didn't feel like a serious lens.

Even stopped down the new lens is a winner. At longer focal lengths they are similar. Much less coma for point light sources at night as well even wide open.The Sigma wasn't quite the equal to the primes wide open but very close stopped down which is more than acceptable for an all-purpose lens given the price and size.Are there downsides? Yes. I find it initially misfocuses some of the time which is a problem if you aren't paying attention (shooting from the hip, etc.). Give it a second to acquire focus and it will be fine. None of my other lenses exhibit this oddity. Tracking autofocus with the a6600 works very well as does burst autofocus and video autofocus.Also, the filter size is small so you'll save money on polarizers or ND filters. Sigma really nailed this lens design and didn't have to sacrifice optical quality like Sony did with the horrible 16-50 kit lens.

Using it on my Sony FX30 for documentaries
26 February 2023

I'm using this lens on my Sony FX30 for making documentaries. It's the perfect combination of form, function and price. Its light weight and small size makes it easy to carry and store. Its 18-50mm focal length and sharp performance fits the vast majority of my needs when making a documentary. Its price represents very good value. I considered other lenses such as the Tamron 17-70mm (too heavy) and the Sony 24-70mm GMII (too expensive) but I've been very happy with the choice I made.

Wanted to love this lens but....
17 January 2023

I recently bought the Fuji XT-5. I already own the Fuji 16-55 - 2.8 but it's SO big/heavy I rarely use it. Saw how small this Sigma 2.8 was, plus read several very positive reviews so decided t buy it. Long story short I found this lens to be super soft at some focal lengths, ESP 18mm. I know most zoom lenses need compromise a bit on the wide and or fully zoomed in ends. Thing is esp around 18-22mm no matter what the aperture I used, a large part of the corners were SUPER soft like almost smearing soft. I'm talking like smartphone soft. I live near some mountains and there's a paved road on a big incline where I can overlook a ton of houses, a lake..and some mountains in the background. Again even if I stopped down to f 7-ish or/f11 all of the houses in the corners ... MoreI recently bought the Fuji XT-5. I already own the Fuji 16-55 - 2.8 but it's SO big/heavy I rarely use it.

I live near some mountains and there's a paved road on a big incline where I can overlook a ton of houses, a lake..and some mountains in the background. Again even if I stopped down to f 7-ish or/f11 all of the houses in the corners looked like mush or just lacking any kind of detail. It drove me so crazy I returned to the same spot with my Ricoh GRIII as it's also 18mm - 28mm equivalent full frame.. Even at 2.8 the Ricoh was like 5 times more sharp than this Sigma esp in the corners. Shooting in other settings with this Sigma ex: on streets, buildings etc..I did not notice the wide end being so mushy in the corners, so you may not notice this till you have the opportunity to take some wide landscape pictures. Also I'd like to say MAYBE? this is not so much the fault of THIS lens. I have older Fuji primes too, The 23mm 1.4 and 35 1.4...and though generally sharper than this Sigma, all my older Fuji lenses don't look that great or SHARP overall with the new 40meg sensor. I know Fuji has a recommended list of newer lenses to pair with the new 40meg sensor...My older primes were not on the list..and they are not going to list any third party lenses, aka this Sigma. One other thing I did not like but got used to is, the manual focus ring is totally flush with the barrel. It's almost impossible to use it without being super careful you are not grabbing the barrel too. It's not a big deal, but you will notice this. Now that I bashed this lens, I LOVE the overall size of it, it feels very well made, zooming in out feels smooth and silky. It MAY be this lens may just be better suited for the 24/26 meg Fuji sensors and perhaps you would not notice the almost smearing I saw in the corners on the 40 meg XT-5. I admit I DO pixel peep a bit! If you don't zoom into 100% on a 40 meg photo, this lens renders everything very well, great Fuji color..even rather good overall detail, it focuses quickly and quietly, and I LOVE it's size/LOVE it's price. But unless MAYBE I just got a bad or soft copy which IS possible...this lens overall, is rather soft on my XT5 at least, vs a cyclically sharp type lens, and that may be fine...but doesn't work for my taste.
