I think it's the combination of all of the below:

1. The 28-45 gets shot a lot at 28 (deeper) and 45 (more compressed). 35 is an "expected" FOV to my brain.

2. The distortion correction of the 28-45 produces images with a mild anamorphic feeling. The Leica Q's distortion corrected 28mm (25mm actual) lens imparts a similar look to its images.

3. The near APO level of correction in the 28-45 adds to the feeling of depth. I assume lens coating improvements are at work here, too.

4. Some of the images in the 35/1.2 thread have the shadows lifted too much, which to my eye reduces the feeling of depth.


Quote below taken from:

https://diglloyd.com/blog/2024/20240828_0800-SigmaFE28_45f1_8-Conclusions.html

Have I ever seen a zoom with this lovely a level of color correction? Few prime lenses are this well corrected. Very few. Indeed, the only lens I am sure is better corrected is the mostly fluorite Coastal Optics 60mm f/4 UV-VIS-IR APO-Macro. And that specialty lens is 2 1/3 stops slower/darker and manual focus and a DSLR lens and less sharp and with more field curvature.

Sigma FE 28-45mm f/1.8 DG DN Art: Conclusions

At about $1349, it offers one of the best value propositions on the market today.

Gorgeous images a cut way above... if that appeals, then my detailed review is must read.

I see that depth, often even stopped down. I haven't looked at too many shots from the 35/1.2 to comment on it though.

I find it super fun to walk around with a 28-45 f/1.8 "prime" though. It acts more like a prime, just a very flexible one. (While those shooting zooms will say it's not flexible enough.)

I never seem to get to the right place at the right time when it comes to sunflowers. But when I do, I always find it challenging to capture "hot" yellow. In any case, here are some attempts.

I'm starting to enjoy Lloyd's work, talk about stating your mind, lol. His videos are a revelation after the more razzamatazz guys who just talk their take. A very insightful and thoughtful piece, HDM, thanks very much. It's good to see Sigma pleasing a lot of people, for different reasons too. I feel this 28-45mm would be a great travel lens, really great and with reliable imaging.

'Flexibility' can be had by adding a wide prime of your choice, and a short telephoto. I kind of do this with a 'centering zoom', a general purpose but slow 35-70 and favourite primes for low light or special needs. I bet in such a setup, the Sigma zoom would do 75% plus of total shots. Not many primes will keep up, LC is right about that. It was obvious from the first viewing.

We used to calculate range ratios for zooms, before the universal 24-70s arrived. 2:1 (35-70) fell out of favour. My Fuji 645zi had a 55-90mm (like 32-54mm in full frame). It had the same ratio as this Sigma around 1.6:1. Lovely images, every bit as good overall as the prime it replaced in a previous camera. Sigma are closing in on 'something for everyone'.

Hi Tim, these are great. For me the third image is the money shot. Classic. I actually sent someone a gift card the other day with a lovely photo of a sunflower, just like this, on the front. Your image is better -- more depth and dimension, truer colours, just the right framing by the leaves and contrast with the deep blue sky, etc. Suggest you send a copy to Hallmark!!

Wow how this thread has grown since I last posted when I ordered the lens a few weeks back - many fantastic samples (technically and creatively) and insights for me to wade through!

So, I like the lens more than I thought I would, given that 28mm start (I'm a 20/24mm junkie). The IQ and creative opportunities this lens affords are simply unmatched. From my experience - I am sure this will have been shared before by others - the best way to psychologically approach and use this lens is not as a replacement for a standard zoom, but as your favourite prime (take your pick between 28mm, 35mm, 45/50mm) that happens to give you a little bit of flexibility to punch in or out to give you a slightly different framing or if you're in a tight spot.

In my camera bag then, with 50mm being another of my favourite FLs, this lens becomes a direct competitor to the 50/1.2 GM. A couple of samples from a casual walk around London town, shot handheld using A7C II, AF-S (best of 3 shots), RAW with minimal post-processing using Capture One (low sharpening and low NR):

Sigma 28-45 left (zoomed to 43mm), Sony 50 1.2 right, both at F/1.8. Shadows +45 added to both images due to mitigate backlight
100% bottom crop with bokeh transitions
100% right crop
100% background bokeh crop

Sony 50/1.2 @ F/1.2 (left), @ F/1.8 (centre); Sigma 28-45 @ 45mm F/1.8 (right)
100% centre crop
100% bokeh transition crop
100% background bokeh crop

My observations:
- I was struck by how much the 28-45 rendered like a top-notch prime. I've only shown the samples at the long end here but trust me, its performance is consistent across the zoom range. This is one of the reasons why at the beginning I said you should treat this zoom lens like your favourite prime that gives a little flexiblity to zoom.
- Sharpness-wise, I can't tell the two lenses apart.
- Both lenses have exactly the same exposure at F/1.8 which against suggests prime-like light transmission qualities of the Sigma.
- Unsurprisingly, the Sony 50/1.2 bigger bokeh balls than the 28-45 when stopped down to the same aperture (F/1.8). This is to be expected when you compare any lens at max aperture vs one that has a faster max aperture but stopped down, plus given the fact that the GM has a longer FL. On balance I'd say the Sony's bokeh has a subtly creamier quality overall but the Sigma also looks very impressive - in the foliage in particular, notwithstanding slight focus differences, some types of foliage look better on the Sigma than on the Sony (less so for others).
- Transitions are also marginally smoother with the 50 - look at the wood grille in the cafe shot and the overlapping foliage in the outdoor shoot.
- Interestingly, in the cafe shot, I can see that although the Sony looks more contrasty around the periphery, the out-of-focus background in the centre looks obviously punchier in the Sigma. In my view the result is not unpleasant for the Sigma to capture the colour and bustle of the Marylebone scene, and the Sony's background almost looks too muted. When I look at the comparisons across F/1.2 and F/1.8 outdoors, I can also see this difference too with the Sigma having a slight advantage in centre contrast (slightly more obvious compared against the F/1.2 wide open). The Sigma having slightly more vignetting might partially explain why

All in all, the fact that the Sigma 28-45 performs on a level that is too close to call in many areas with what many regard as the best 50mm lens for Sony is mightily impressive. When you throw usability and versatility into the mix, the Sigma wins hands down. Yes the 50mm gives you an extra stop but when the Sigma 28-45 does 90% of what it does (plus more) it is very difficult to justify keeping the GM in the camera bag.

Very well said!
I came to similar conclusions, giving the prime only a slight advantage in rendering (smoothness, etc.) minus the obvious aperture difference .
I also think the Sigma fits better as a "more than a prime" rather than a zoom competition. Paradoxically, that's the reason why I gave up on it (for now ), as I don't want to stop shooting with my primes...

Doesn't hurt to repeat this, as I'm reading way too often the range is too short for a zoom. :-)

Bigger at same aperture is nice, but more round bokeh in a larger part of the frame is important to me as well.

A stop is a stop. More creamy bokeh is always nice to have. Bigger bokeh balls and more round bokeh balls (at same aperture) are worth it as well to me. So the GM stays.
The biggest problem of the Sigma 28-45mm: it can not only be seen as a replacement for a 50mm, but also as a replacement of a 28mm, in my case, the 28mm f/1.4 Art. And that's where the GAS creeps into my brain, heart and soul..... Luckily there are still solid arguments to stick with the f/1.4 Art:
- it fits my Canon EOS R5
- and it does so being compatible with the drop in filter adapter
- I like how the EOS R5 performs with the 105mm f/1.4 Art, and some other EF lenses, so I don't want to sell it. The R5 is a better body than the A7IV.
- It works great on the A7IV via MC-11 as well.
- I can do EOS R5 + 28mm Art + Sony + 50mm f/1.2 GM, while I can't do EOS R5 + 28-45mm + 50mm f/1.2 GM. (just don't mention 28-45mm + 105mm!)
- resale value of the 28mm Art is pretty low
- actually I should reserve the funds to upgrade from the A7IV

So I really should stop reading this topic. I'm not buying it. But it's a great lens, as it really breaks the boring rigidity of those (yes, that's just my opinion) 35mm focal length primes being nor here or there, whereas this lens is BOTH here AND there. That's awesome.

Options are good, and absolutely can't argue with a desire to use faster primes (or primes in general). Everything has pros and cons and everyone has they own approach and style. I do think the 28-45 gives the 40/1.4 a run at f/1.8. But with my copies, the 40/1.4 is stronger at the edges at distance, stopped down from wide open.

I tend to prefer primes, and f/1.8 is plenty fast enough for how I normally shoot (definitely not speaking for others). This range works well for me, and the flexibility is awesome, and I really like the results from the lens.

But absolutely understand a preference for faster primes.

I still think overall 35GM is a better choice, and the 28-45 can't reach that level my 20 1.8g, 35gm, 50 1.2gm provide. All of them has advantage, they are smaller, the 20g is lot wider, 35GM balances extremely well on A7RIV, 50 1.2 has other world rendrering. But 95% of my shots on 28-50 range, I like Sigma built quality and rendering (had 35 1.2), and the internal zoom makes the lens prime like along with 1.8 and IQ. I don't think I ever let go my trio, but definitely want to try once the 28-45.

Can't blame anyone for not letting go of their trinity!

On the other hand, if a person was starting from scratch...the 28-45mm is basically the same price as the 35GM.

It's going to be dependent on your tastes rather than any inherent major quality differences. The very fact that this is a zoom placed in this company should be sufficient to inform you of that. I personally prefer what I see above, so it's no surprise.

'Smoothness' is a double-edged sword - it tells you the designers and the money men behind them are working for that particular look. The alternative taken by Sigma here is very close to how Cosina design their trademark OOF transitions, which emphasises using the background to steadily fade off with great elegance.

It's much harder to achieve than to simply do a lot of early and persistent blur as subject-background distance is gained. If you rush to OOF too fast, you flatten the visual cues that provide depth perception to the image. It won't matter what your mind thinks about this, because your visual system sees it first and forms that recognition ahead of your conscious appraisal. Yes, it's science.

Believe it or not, your visual system is looking for progressive fade from sharpness, correlated with distance. Seen most clearly in the room set above (see the wall chart board, for example). Having said this much, it's obviously down to preferences. And they tend to stick in people - Leica went with the blur wall background in many older lenses and many people love it. Cosina released the 50/1 and did it their way, you can check it out here, if interested.

One approach separates the in-focus material very strongly (Sigma already do this in the 35/1.2), the other approach brings in the other image content in a progression with distance from the subject. The marketeers have sold the full bokeh look very successfully, but it runs against your innate depth perception. This zoom is a very engaging lens, with wonderful other characteristics, notably fine microcontrast and microcolor - topics for another day.

See the GM's CA also in the wood cabinet crop (both at f1.8). And the onset rate of blur showing in the device sitting on the cabinet. It's not surprising in a lens destined for weddings, events, etc. is it?

Fast lenses tend to carry their characteristics into smaller apertures, as we see here. They won't magically transform themselves. If you want image depth, stay clear of ultra fast lenses. That's also $1900 -vs- $1340, with 170 grams different weight. Just pointing that out. The zoom obviously has great crop potential at its long end, making it an effective, say, 28-55mm or more, depending on standards and end use.

I'm curious, has this impacted what your carry around to shoot, or your long-term plans? I understand the sigma may be getting more love now because it is new. When it comes to taking out this zoom vs your 50 & 35 APO what way are you leaning? Or do you see this more for times when you don't have as much flexibility to zoom with feet?

Time will tell. If you look at what I shoot, I often return to spots over and over again, often as a day trip or even just a morning. Often you'll see the same compositions across those visits, occasionally I'll mix things up a bit. For that type of shooting, I could see me taking the CVs. But when I'm going somewhere new, or I have my family with me....or I'm pressed for time, I could see me using the CV a lot. I do a lot of shooting between 28-45, as some of you might know, I really like 28mm. So having the flexibility of a fast 'ish prime like lens that covers the range from 28-45......it really works for me. And I really like the results it delivers.

I tend to shoot my 14-24 over my primes, except for the Loxia 25 which is usually in my bag as well.

So I don't know. But given that enjoy shooting the lens and I really like the results....those types of lenses will be used more often than not.

So I still see me using my CVs. I just don't know what the split is going to be. I will say that for my waterfall shooting, the Sigma might get more usage than the CVs. I am often working in tight spaces, there is always something you have to try to work around. Add to that it being a wet often semi drizzly endeavor, I feel a little better having the Sigma out in the elements.

I googled the location of some of the waterfalls you go to. My grandma lived in the area and I wondered where these things were. It seems you get around a fair bit. I have been to a couple locations you frequent. There is a mansion next to the river north of Harrisburg, also I have been to Watkins glen, and of course Hershey.

Seeing the pictures from this lens I have been very impressed by it. I certainly underestimated it initially. It will be interesting what tomorrow brings with the Sigma 28-105/2.8 release.

Thank you for your insights which I hadn't considered. Appreciate your scientific angle to what might otherwise be thought of as "3D pop"? Re. the "wood cabinet crop", I presume you were referring to my head-to-head shots from the cafe (not sure what the device on the cabinet was, possibly the payment card machine?). I do see the more gradual transition in the Sigma vs the abrupt falloff of the Sony.

Fort Hunter is that mansion, it's about 20-25 minutes from my house. I can hear the concerts at Hershey in my family room if I shut off the TV (wind might need to be blowing in the right direction too. )

I've only been to Watkins Glen once, and part of the trails were closed...and my one son has some medical issues that make it hard for him sometimes to do stuff like that. Although he's older now, and might be able to do it. I frequent Ricketts Glen quite a bit, as it's a doable day trip for me.

From the leaked pictures, it looks like it will dwarf the 28-45, I guess we'll see soon enough.

The cafe image is a little disconcerting because as a quickly chosen shot (I imagine) it still shows the great differences very well. I think this delta may be replicated in many such comparisons, were anyone to do them.

Rates of focus fade and its onset by subject-motif distance is one of many characteristics to elude reviewers, but it's vital to landscape photography and much more besides. Notice how little we see of 'focus stacking' in forum chat these days? The 'all in focus' look may not be best for many compositions.

The visual effects before the brain processing is interesting, and it's why subliminal advertising is banned in some countries (but not the US). Culture is full of it, the 'hidden persuaders'.

People are going to have different reasons for choosing what they want, but image depth is real and often desirable. And lenses do render it differently, so this set was excellent for that, thank you. Many people struggle to see image depth, just like some middle aged people don't see depth as well driving at night as they once did. Much of visual appreciation is about learned responses.

Based on my comparisons, the Samyang puts up a good (actually I'd say great) performance at both 35mm and 45mm, but the Sigma does have a noticeable if slight edge in terms of contrast. The Samyang definitely has more nervous looking OOF areas and ever so slight double-lining, and the Sigma noticeably but again slightly cleaner in terms of OOF rendering. Samyang has noticeable but slight colour fringing around highlights which is non-existent in the Sigma, but Sigma has the trademark warm cast.

What does this tell us? Probably not very much. other than that the Sigma is even better than a zoom that is known to be very good. But we could have guessed that?
