I don´t believe the RF 20mm F2.8 will make it into production.
- trinity zoom territory
- too close to the 24mm
- Sigma 20mm F1.4 would seriously hurt Canons sales on a 20mm F2.8, especially if the figure out to produce it as a true RF mount lense.
This lens (RF 20/2.8) is for me. I love it. And I already own a Sigma 20/1.4.
here is why I want a 20/2.8:
I love the Sigma 20/1.4 for people shots and isolation in very environmental shots, weddings, reportage etc.
However when I am hiking in the mountains for nature and landscape photography I need something light like a 18/2.8 or 20/2.8. Such a lens covers wide angle below the standard Zoom starting at 24mm without adding too much weight to the combo. I would never carry a "trinity" of ANY given max. f-stop in the mountains.
So far in the mountains I am doing all my nature-photography with FF-Sony because they have the lightest lenses: 200-600mm/5.6, 28-60mm/4.0-5.6, Pentax close-up Diopter, Meike extension tubes, Samyang 18mm/2.8
This covers most of my needs and weighs a fraction of what I'd have to carry if I was to plan on using Canon-equipment.
With an excellent 20/2.8 (which btw was long overdue in the EF-System - the old modell was terrible), Canon might win me back when it comes to photography in the mountains. Just wished, Canon made an execellent lightweight FF-Standardzoom, similar to Sony's 28-60mm.
BTW: When I am doing landscape shots in flat terrain or relying on a car as transport, I still prefer the flexibility of my 16-35/4.0mm
In any case, the 15-35/2.8 is not for me - it either does not offer enough isolation for people photography or is too expensive and heavy for the landscape photography I do.
Thanks, Canon, for finally planning on some lightweight RF glass!
Keep it comin'.
