Sigma has done a remarkable job in the lens markets, both as a third party supplier, and as an OEM supporter.

Of course, most of the better Sigma lenses are FIRST PARTY NATIVE lenses on Leica, Panasonic, and Sigma L-Mount bodies. Sigma is a full member of the Leica L-Mount Alliance. At this writing, well over 90 L-Mount lenses are available, including 15 from Sigma.

Sigma makes an MC-21 lens adapter to fit Canon EF/EF-S mount lenses onto L-Mount bodies. The one video demo I saw Kai Wong do was impressive. He fit several Canon lenses on a Panasonic S5 Mark II with the Sigma adapter. They all worked.

The title of this thread is a bit misleading as Sigma is not producing lenses for Canon or Nikon mirrorless cameras--neither Canon nor Nikon are allowing Sigma to do so at this point. Thus the use of Sigma lenses on Canon or Nikon mirrorless bodies involves the use of adapters, which is less than ideal.

Sigma produces L-mount lenses, and of course they make lenses for the Sony E-mount. Early on, Sigma adapted Art lenses designed for DSLRs to the Sony E-mount. More recently, they have developed a line of lenses specifically for the Sony e-mount, designated as DG DN. These are quite good, but so far the only significant contribution to mirrorless systems.

Duh, they are Sigma lenses on mirrorless.
Stupid response as it is highly accurate.

If the adapted lenses do what they are supposed to do, why is it less than ideal? I use my adapted EF mount Sigma lenses on my R5 and R7 and have not had any problems at all. They work just fine. Not having to spend thousands of dollars on RF lenses sounds pretty ideal to me.

There is a difference between adapted lenses and lenses used with an adapter.

You can use any DSLR lens (including Sigmas) on a mirrorless system using an adapter. I call this less than ideal because you lose function--anywhere from AF being slower and/or less accurate to having to operate the lens like a fully manual lens. If you are happy with the outcomes then stick with it.

In the early years of Sony mirrorless, Sigma adapted existing DSLR lenses in the Art series, which essentially consisted of lengthening the neck because of the much shorter flange distance in MILCs and using a Sony lens mount. These actually work like native lenses, but they are very large and heavy. Their more recent DG DN lenses are specifically designed for Sony, are much more compact, and of course perform well.

To be clear, there are significant lens flange-to-sensor distance differences between dSLR lenses and mirrorless lenses. The shorter flange distance on mirrorless designs, due to elimination of the mirror box, enables better optical designs, especially for wide angle lenses and short zooms. Lenses specifically designed for mirrorless bodies are likely to perform better than their older dSLR versions, both because of the shorter flange-to-sensor distance, and due to improvements in computer-aided design, lens coatings, and lens manufacturing processes.

All THAT said, dSLR lenses that are correctly adapted to mirrorless bodies should perform as well OR BETTER than they did on dSLRs. Most people notice an improvement in autofocus performance over what they had on their older dSLR bodies. Optical performance should be the same, although better sensors in the mirrorless bodies may eke out a bit more image quality from an older lens.

When mounting some older lenses on very high megapixel count cameras, you reach a point where the lens cannot resolve what the sensor can record. That is where newer, better, designed-for-mirrorless lenses excel. At 24MP, you probably won't have issues with older dSLR lenses. At 60+ MP, you probably want the latest, greatest glass you can find. OR, you need to examine your reasons for buying a 60 MP camera, to be sure they are sound! (Bias-ply tires don't work well on a high end sports car, do they?)

I have been using mount adapted lenses on my digital cameras for years.
I especially like using good Minolta lenses on my Sony mirror less camera.

I have always favored lenses made by the camera manufacturer. I have never had an issue with them.
Sigma has come a long way as a lens manufacturer. I am sure Sigma is making excellent optics and I have a 60mm f2.8 Art that I use with my Olympus as a short tele and for portraits. The images retain excellent details and the lens is sharp. This is the only lens I have that is not original equipment.

Today the price of independent lenses, in some cases, is higher than the price of a lens manufactured for the camera. The lenses manufactured by Panasonic, that bear the name Leica, are of excellent quality. My experience using Panasonic lenses with my Olympus bodies have been a pleasant one. Those lenses are sharp and resolve fine details to perfection.

Sigma right now is one of the best independent manufacturer of lenses.

Leica, Panasonic, and Sigma formed the L-Mount Alliance to ensure a standard set of specifications applies to the lens mount and electronics interface of L-Mount bodies from all three camera companies. You can put Leica lenses on Sigma or Panasonic full frame L-Mount Bodies. Or, you can put Panasonic lenses on Leica or Sigma L-Mount bodies. Or you can put Sigma lenses on Leica or Panasonic L-Mount bodies. They will work as first party OEM lenses in any combination. It's an open alliance, too, so any manufacturer can license the L-Mount, so long as they agree to support the standard to the letter.

Leica and Panasonic have worked together for a very long time. Panasonic benefits from Leica's lens design and manufacturing techniques, and Leica benefits from Panasonic's electronics expertise. Together, they have formed a separate collaborative "L-Squared" (L^2) Alliance for camera engine design and manufacturing. Their first digital camera engine is in the Lumix S5 Mark II.

Depends on the lens and adapter.
Many adapted lenses perform better and gain new functions.
So it is not true all adapted lenses do worse including Sigma.

I read long ago that Sigma and a few other third party lens makers often subcontract with the major brands like Canon, Nikon etc. when they need more production capacity. They produce components and complete lenses to the specs and then branded for the majors.
Do they still do this, probably, but I haven't seen anything about it lately?
