Samyang to expand their autofocus lens selection for Canon ahead of CP+

Yet, even with a filter, Sigma Arts are NOT wheather sealed...

Ironically the Samsung 14mm AF lens IS weather sealed. Well, it has a rubber seal at the base of the lens which is most welcome. Cannot vouch for the rest of the build, but the focusing ring is 'focus by wire', so little chance of weather ingress there, and there is no front filter option anyway.

Sigmas are certainly superior in weight!

You're missing the point. If there are more competitions, then it's better for the consumers. Before Sigma Art came along, there weren't any direct competitor for the EF. As for the weight, let's figure that out.

In 2008, the 5D mark II (21mp) was commonly coupled with 80oz of lenses (Canon 20-70mm f/2.8 and 70-200 f/2.8). In 2012, the 5D mark III (30mp) changed the way photogs carry the lenses, shooting primarily with primes, weighing about 35oz (i.e. Canon 35mm f/1.4 and 85mm f/1.8) or 60oz w/ 85mm f/1.4 instead. If we compare apple-to-apple, the sigma art 35mm and 85mm weighs tiny bit more, 0.6oz, than the Canon L.

What you're saying isn't entirely true, quite uneducated guess. Thanks for your comments.

Yes, let's take a look at the lens weight shall we (from TDP). All Ls versus Sigma Sport/Art except for 105mm where Nikon's f/1.4 is used as a comparison.

Lens Canon Sigma
14mm 22.6 (2007) 39.2 (2017)
24mm 24 (2008) 24.5 (2015)
35mm 27.9 (2015) 24.5 (2012)
50mm 22.1 (2006) 30.2 (2014)
85mm 34.2 (2017) 41.8 (2016)
105mm Nikon 36.5 61.8 (2017)
135mm 27.5 (1996) 42.4 (2017)
24-70 29.5 (2012) 37.2 (2017)
70-200 57.9 (2018) 66.9 (2018)

So, let's see... yes, the Sigma's do generally weight significantly more than Canon, especially for lens 2016 and after. Granted the Sigma 14mm has a significantly larger max aperture than the Canon, but I think the trend is pretty clear in Del Paso's favor. So who is cherry picking data now?

Read the forums, Amazon reviews etc...
Sigma has been and is still selling many "tasty" lemons.
And what about wheather sealing of the Art series? EF L lenses are all wheather sealed, extremely important in dusty, humid or tropical regions!

Well, Sigma has actually started adding weather-sealing to their Art series lenses, the last 3 lenses (I believe - or maybe last 4) all have some weather-sealing. (I believe this is a result of, 'if you are charging nearly 1st party (OEM) prices, then you better be including some amount of weather-sealing like OEM's do. Although, it could be the fact that Tamron's newer lenses all have weather-sealing... Or the recognition that if you want to increase sales more - adding weather-sealing is a pretty cheap way to garner a few more sales.

Thanks for the data but I'm not following your narrative, or perhaps there's gaps in your explanation that I can't make sense of.

If you explain in detail, I would like you to create a scenario where a photographer would carry all 9 lenses at the same time; hence, the reason you listed out all of the lenses?. While that's a wild assumption, which is unlikely a competent photog would do but that's where the gaps may be to your narratives. Again, in 2008 when the 5D mark ii set the a high benchmark for FF, in use of photo and video, 24-70mm f/2.8 and 70-200 f/2.8IS was a popular set of lenses people (including myself) own and use. When the 5D mark iii came out w/ higher resolution, limiting ourselves to w/ 35mm f/1.4L and 85mm f/1.8 was feasible.

Back to my original point about competition - there's even more demand now (due to high res sensor) for people to shoot primes. Prime lenses are profitable to make and a lot less complex to design and manufacturer. Again, I'm not making a point about the brands and I've owned Canon, Sigma, and Samyang at one point in time - they're just tools, but I like to replace them at a reasonable costs and competitions are good for consumers like myself.
