There is no Sigma 24mm f/1.4 ART yet (thus an unfair comparison), but the Canon 24mm f/2.8 IS seems to be dropping the ball a bit:
The Sigma 24mm f/1.4 ART is rumored to be heavier and more expensive as the 35mm Art.
Although the mentioned Canon IS Prime lenses are not as good wide open, they have some clear advantages:
- They are much smaller and lighter (the combined weight of the 24mm and 35mm Canons is actually less than a single Sigma 35mm ART, a big bonus when hiking);
- They are (much) cheaper (the possible savings could bring a 5DmkIII in reach, but likely be spend on more glass);
- They offer IS (which I don’t care about, but could be good for filming).
Am I missing something, or is this actually a viable option? Any good experiences using these Canon lenses for landscapes?
There is an older Canon EF 24mm f/2.8 which is near as good optically as the new stabilized version, only cheaper and smaller.
