The Q4 announcement spree from manufacturers looks to be ramping up, as SIGMA will announce two new Contemporary prime lenses soon.
SIGMA will announce the following lenses
- 24mm f/2 DG DN Contemporary
- 90mm f/2.8 DG DN Contemporary
Both of these lenses are for full-frame mirrorless applications, which likely means they're for Sony's E-Mount and SIGMA, Leica, and Panasonic's L-Mount.
I do not expect these two lenses to be SIGMA's first foray into the RF mount, which I do wish was happening.
Edit: curious to find out the max mag ratio of 24mm lens. 24mm lens with .5x mag ratio was a good wide angle macro for herpers.
Those are a mouthful but at least every part of those lens names maps to the spec (except for the III which is essentially a version number). The name describes the lens, albeit at length. What does "Contemporary" actually mean in relation to a lens?
Sigma and Tamron are producing Sony e-mount lenses. I imagine there must be some agreement with Sony, or else they've reverse-engineered without legal repercussions. These third-party manufacturers are not (yet) producing lenses for Canon. And that's too bad. I think more people would jump to Canon or else upgrade from EF to R if a good selection of third-party lenses were available.. I think Canon is at a competitive disadvantage to Sony in this regard.
Food for thought: Imagine if Microsoft only allowed their own software to run on Windows...
DN= lens for mirrorless cameras
Why DN and DG what do they stand for.
I'm not sure about DG. Sigma has DC lenses, which I think stands for digital (or maybe DSLR?) compact, which are for APS-C sensor cameras. Regarding DG, the G definitely indicates full frame, and I think the G may have even been similar to Canon's L at one time, so DG refers to the G series for full frame in the DSLR/digital age.
Particularly now sigma uses art, sport and contemporary, I think sigma could probably consider reducing the number of teens they use :)
EDIT: Actually, I think maybe I'm wrong about DG. I think possibly Sigma used to have a G series and a DG series, which were both for full-frame cameras, and the DG series was the higher end series (with D standing for deluxe?). The DC series was equivalent to DG but for ASP-C sensor cameras. Basically, I'm just not sure!
