There’s only one little thing with Sigma zooms, Sigma zoom ring turn in the opposite direction of Sony zoom rings. 😵‍💫 I think however that Sigma lenses, including zooms, are still the most attractive third party lenses. 🙂

Sigma has recently established their own Nordic subsidiary too, https://www.sigma-imaging.no/ 😊

I have some Sony zooms too but I didn't even notice the different zooming turn orientation on the Sigmas before somebody mentioned it and I compared to some of my Sony zooms

It hasn't bothered me in actual use whereas Tamron's different order of rings was more noticeable to me. I use primes more often so I guess I haven't developed much muscle memory for the zoom ring orientation.

Have you noticed some differences in Sigma lens availability and support after the Nordic subsidiary was established? I saw the announcement about it earlier too.

I haven’t bought Sigma lenses lately, but availability of Sigma products appear very good to me. Also I like that they have a service organization in the Nordics, so a lens doesn’t need to be shipped far away. If you buy Zeiss, everything needs to go to Oberkochen in Germany, not that far, but still. Sigma’s Nordic repair shop seems to be located in Stockholm, with a turnaround of five days unless they need parts from Japan.

I have a couple of candidates I’m looking at now, 24/3.5 and 100-400mm for Sony.

According to lenstip.com the Sigma 24/3.5 has much less distortion than the Sony 24/2.8 (1.5% vs 8% in raw). This lens would be part of a kit of small primes.

I would also like a lightweight 100-400mm, so Sigma is the strongest candidate. I think it makes sense in combination with the Sony 200-600mm.

Based on what I see here on the 28-70, the distortion is a deal breaker. I seldom use lens profile correction for distortion, and moustache is a non-starter for me for linear perspective on buildings and objects.

I like Sigma Contemporary series a lot, so I have bought the whole set of I-series lenses + 28-70/2.8 in E-mount for my A7C and I almost duplicated the same selection in L-mount for my Sigma fp (skipped the 65/2 in L since I figured the zoom can cover the long end well and provides more flexible coverage). 24/3.5 is definitely nice, it's one of my favorites among those.

I don't have a lot of use for big fast primes nowadays and I've never shot much at tele end beyond 200mm but if Sigma rolls out a nice 70-200/2.8 at some point I would consider it for future event use in E-mount. They might also expand I-series at some point but at least in Japan their zooms and some of the Art series primes seem to sell much more than I-series in general and I think they'll be busy bringing out a fuller set of Art primes as DG DN for a while + a few more zooms.

Good to hear you like the Sigma 24/3.5.

I checked the focus and zoom rings, and you’re right, Sigma and Sony place the zoom and focus rings the same way, with a couple of exceptions for both makers. Tamron always places the focus ring closest to the lens mount, so almost always opposite of Sigma and Sony. I had not thought of this before you mentioned it.

Currently $810 with Edu discount on BH and tax free. Pretty good deal for a compact f2.8 zoom. Also wish they make a 18-28 f2.8 with this rendering and size.

A few samples. And yes I somehow missed that the camera was set at ISO 320. Usually shoot auto, but had set it manually and forgot.

Some quick portraits with a somewhat unforgiving background. I think it handles OOF areas well. (Note: not professional models).

I'm wondering how sharp is sharp enough for this lens.
I bought it last week and I really like its size/weight and the way it handles.

I just took some shots to find out how sharp it is. I mainly compared it to the Sigma 24-70mm f2.8.

The question is, what is "sharp enough"? I took those pictures on different days so I don't want to comment on the colors since lightning was different.

comparison at 70mm. f2.8; f4.0, F5.6.

Sigma 28-70 left, Sigma 24-70 right

100% crop from the center.

But then again, just tried some "real world" comparison shots and well, of course the 28-70mm is a bit softer at 70mm, but it seems to be fine with me. It also gains contrast when stopping down. But that doesn't mean that it's bad before.

Nice photos!

The background on the first one does look a bit busy though.
Did anyone have a chance to compare bokeh to the Tamron 28-75 G2?

Real world. It‘s not a portrait lens. But for casual portraits it will do the job I think.

Yes, I'd say the bokeh deteriorates at the corners. Around the subject in the first one, however, I think it handles those difficult areas pretty well. There's a lot going on behind him and there's a uniform smoothness that only becomes nervous toward the edges (the top left corner). A quick swipe of the brush tool in LR can easily smooth those areas out, though. For me, I really like the rendering, the size and the weight of the Sigma. The G2 might be sharper and it may have better bokeh (which I doubt), but it's bigger than what I want to carry.

@6683 my casual testing concluded the 28-70 better meets my needs. Not sure how some people say it whether it is called detail, resolution or micro contrast but the images from my 28-70 have higher overall IQ then my 28-60 on my A7C

Not a great comparison because the images were taken many months apart in very different conditions, but the scene is approximately the same. For landscape uses, they are probably pretty similar. The Sigma image was accidently shot at ISO 320, and I raised the shadows a lot more because of the intensity of the light, so it shows more noise. I think the level of detail is very similar, with maybe the Sigma showing a hair more detail on the right side crop. For some reason the Exif on the Sigma shot won't show, but you can see the settings on the screenshot 100% crops that come below. Hope this helps.
