Sigma released the 24/2 and 90/2.8.

I do not understand the 90/2.8. It is not cheaper then the 85/1.8 lenses nor is it a macro. It probably is quite good and it is lighter and smaller then the Sony 85/1.8. A 90/2 would make more sense I think.

The 24/2 makes more sense, but 24mm is a crowded market: Sony, Samyang, Tamron and Sigma themselves all have one or more 24mm lenses. I would have liked a 28mm lens as the Sony 28/2 is fine, but not the best.

What do you think?

It is nice to have more options, but I am not much interested in either of these. Sigma is making some lovely lenses. The 65mm is superb. I am very happy with it.

As far as wides, I am somewhat interested in finding a better copy of the Tamron 17-28. My experience with their 24mm showed me that their warranty service won't fix optical issues, but I suppose I could try it again.

I know at least one person had been clamoring online for an 85mm F2.8. I respond that Sony sells one for A-mount, and E-mount bodies support it fairly well. Used prices have risen again for it. I must have sold mine at the lowest dip--oh well. I am very happy to have sold the FE 85mm F1.8.

I still have the old Tamron SP 90mm F2.5 52EM which works fine on the LA-EA5. It is fine enough old lens, but I wouldn't miss it. I am sure the Sigma is more corrected than these.

Edit: After watching a review of the 90mm, it is looking more interesting. It is very small.

That's interesting to know as the warranty is something like five years (tied to the first owner).
Same nr of years as Sigma in the Nordic countries.

I guess the issue wasn't present from the start?


As for this i-series, I'm sure they feel good in the hand, though weather sealing is limited to the rear gasket, which seems as good as no weather sealing when I think about what my lenses sometimes have occur to them (light rain). (I'm more careful with the ones without ws, which I would need to be with these).

Both seem rather nice optically, though I've seen mixed bokeh from the 90.

I don't think I'm in the market for either. The small size of the 90mm looks attractive but I already have two 85mm lenses so this doesn't give me anything compelling.

I might have been interested in a 28mm option. That would slot better between my 21mm and 35mm. And as Addy has already pointed out, 24mm primes are a bit of a crowded market currently.

I like the shift to making smaller and lighter lenses. I balked at getting any of the first E-mount lenses Sigma produced because of their size and weight.

To make a 90mm F/2.8 AF lens weighing 295g coming with a 55mm filter thread is quite a feat, IMO. And it's compact enough to be confused with an MF lens of the film days.

BTW: I thought the bokeh is ok viewing the gallery on dpreview.

I think that 90mm has fierce competition - the several 85/1.8 lenses are (also) good, cheaper and not that heavier. The Samyang 75/1.8 is about the same size as the Sigma 90/2.8 but cheaper as well. 90mm is also a bit long on APS-C, but I guess the 65/2 is the competitor for the 75/1.8.

But yes, the size is where Sigma is hoping people will be buying it. I guess it will match the A7c nicely.

Waldo: most shots are bokeh-fine. This one https://www.dpreview.com/sample-galleries/0586964680/sigma-90mm-f2-8-dg-dn-contemporary-sample-gallery-dpreview-tv/3639437927 is less so

wētā: They cater to all kinds now : )

I like small lenses on A7x and A9x cameras. And we like to think from an E-mount perspective, the 90mm has less competition in Sigma's L-mount.

Edit. We live and hopefully learn

I own 35i & 45i Sigma lenses. I hoped that over time one lens would be my fav over the other and sell one of 'em. It turns out over time that both have their own sweetspot in IQ & redering, and I like to swithch between them every other week or so. The small size and premium build is a big plus for me.

I've owned the 65i for a few months, but did not get the grips on this focal lenght, sold it.

Owned the FE1.8/85 for 2 years, liked it for it's way of drawing portraits, not much else. The 90i is a lens I would buy and give it a run for it's money

It seems to be a lens that fits a specific niche, but I wonder if there is enough buyers in that niche. The Sony FE 85/1.8 isn't that much heavier.

Likewise the a7c seems to be a niche product as well, and I don't get the sense it has been a big seller to Dyxum members.

Sigma lenses never had a fabulous reputation until quite recently but I've always liked what they offered. A real sleeper is their 24mm f2.8 macro Super-Wide II in both SRT and AF format (they made them for all the main mounts in the day).
These great wee lenses focus down to about 6" and have very interesting out of focus highlights.
You do have to be a little careful with the AF version because, like many AF Sigmas of the vintage, they may not 'talk' to your camera correctly and getting the chip updated isn't easy nowadays. I have both AF and MF versions

This is what, in the wider sense, makes the change from adopting the A-mount in 2008 to going all in on the E-mount last year, so different.

The (new) A-mount lens options were thin on the ground and a lot of compromises had to be made. If I wanted a long telephoto it was either the cheap SAL 75-300 or the very expensive 70-200/2.8 and 300/2.8 SSM Gs. (Ok, also the 500/8 mirror but that has another whole set of compromises).

Now when I switched I had so much more choice with the Sony and 3rd party lenses. If I wanted a fast, high-performance zoom, it was there. If I wanted something small and compact but still with exceptional image quality, it was there. The number of options at each focal length are completely unlike what we had with the A-mount. Plus we have coverage for a lot of focal lengths we didn't have before.

I see it pop up here and there - nobody is announcing it, but people are buying it. In the US the A7c is US$100,- more expensive then the A7 III - I think that is fair, but it means some people will opt for the A7 III because of price. Over here (EU) the A7c is cheaper, maybe more Europeans are buying the A7c.

It long has been considered an alternative to the Minolta 24/2.8. A really cheap alternative. There were some copies with an old chip, but it seems most were working fine. Also, some had problems with the screw-drive slot. It was discussed at length back in the day and the lens database page has a link to this thread but I am sure there are more.

I disagree - to an extend. There were a lot of small great lenses in A-mount: The Minolta 100/2 is not that much bigger then the Sigma (and a full stop faster), the 135/2.8 and the 24/28/50mm primes were also quite small - compare the A-mount 50/1.4 to the FE-mount 50/1.4. Also, there are only two AF 28mm lenses in FE mount, there are five in A-mount. But I know what you mean, there are more lenses designed after 2000 in FE-mount

And for the reason I came here. Seeing several reviews of the 90mm I still think it is a difficult sell. It is small and sharp, but it has a lot of distortion, has a slow aperture and is quite expensive. It really is a niche lens. I guess that proofs Wētāpunga's point: there are more (niche) options in FE-mount - as long as it isn't 28mm

It's 100e more expensive than the A7iii in Sweden, has a worse vf and no front dial. I kind of get why people say "this smallish lens would do well with the A7c" because the A7c is a bit awkward with larger lenses.

That's an interesting point; distortion profiles for more mainstream lenses would appear in Lightroom and C1 and such rather soon I guess, they'd need for someone to volounteer for Darktable & lensfun. (I should learn to do it one day). And yes, it seems 28mm is rather singled out and excluded.

I just checked NL and Germany and assumed it was EU wide - sorry..
TBH I find the A7c a bit, well, I don't know. I like the A6x00 series cameras with their smallish APS-C lenses (some could benefit from an update) but full frame lenses quickly become awkward. The 16-35/4 on an A7c would be unwieldy while the 10-18/4 (or Tamron's new lens) are perfectly fine on the A6x00 bodies. But if you want full frame and small, the A7c with a small lens makes sense.

I use RAW therapee and like it. It has lenscorrection but it lacks some of the more recent lenses
