While it may simply be a marketing ploy, does the term mean anything substantive? Not meaning to cast any aspersions on anything or anyone — just curious. Thanks

The link does a good job of explaining the Art series. As to the name after dealing with marketing off and on, I'm pretty sure it was chosen to differentiate these high quality lenses from other high quality lenses helping tem to stand out in a crowd.

Link was just what I was after. Thanks to UHH got answering my question. Kind of what I thought.

It was mainly a marketing ploy by a third party lens manufacture to persuade the public that their lenses are good lenses and not produced by purchasing their finished lenses from another company, you see, this third party lens manufacture does not manufacture their own glass, they buy it from the lowest bidder and and then they put them into their lenses. The ART lenses are there better line of third party glass they hope to sell to you. They believe by putting the ART before the lens it will prove to the public that the lens is as good or better than a Sony, Nikon, Canon, or even a Fuji lenses.
Don't be fooled by this ploy, the ART lens is still contain third party glass built by the lowest bidder.
Ride with the brand or be left behind.
Brand lenses cost more, but they last longer, stay sharper over their life, and are worth much more at selling or trading in time. Plus Brand lenses are specifically designed to work with your camera brand, they are not manufactured to work with multiple camera brands like this third party lens manufacture.
Good luck and keep on shooting until the end.
You can write rebuttals to this post until you are blue in the face but facts are facts, third party lens manufactures buy their glass from the lowest bidder.

When referring to Sigma, there is a series of ART lenses of which I own, and use, four. They are more expensive and heavier than their counterparts, but they are also much better -- top-of-the-line. Mine include the 35/1.4, 50/1.4, 135/1.8 and the 24-105/4. The 50 is highly respected by many, including myself, and is considered one of the best 50/1.4 lenses made today. The 35/1.4 is also stellar (IMHO) as is the 135/1.8 (IMHO). I consider the 24-105/4 to be very good. YMMV. Best of luck.

I got my suspicions answered, thanks for the responses. One thing about UHH, there are a whole bunch of folks with strong ideas. 🙄. Live long and prosper 🖖

My most recent purchase was the 24-105 f/4 and so far I really like it. All my lenses are wither Sigma or Tamron.

I hope that the answers above are adequate for your understanding. The reality is that each lens has a profile that can be measured and compared. The "Art" series from Sigma is their highest quality product, irregardless of what some may debate as to how they purchase their raw materials. If the result of that manufactured product can compare to the "brand" names on the "brand" name's own cameras, then it is a worthy product, and can usually save you money. I have several Sigma lenses, and I can tell you that for me, they are perfection. On the other hand, I also have Sony and older Minolta lenses that cannot be beaten, due to the techniques used to manufacture them. So the resultant answer to your question is that each lens has a personality. Find out what you are looking for in a specific focal range, and research the lenses that are available. There is no "one size fits all" in the camera world!

What's a Canon L lens???

I don’t own other Art lenses or non-Art Sigma lenses, but my Sigma Art 24-105 f4 produces excellent results on my Nikon D850 and appears very well-built.

Everything you wanted to know about the Canon L series lenses and maybe more.
