Announced today, Canon's first new 20mm lens in 33 years and two stops faster than the EF 20/2.8. I preordered one at announcement time, looking forward to seeing how it performs for astro. MTFs look similar to the 24/1.4L VCM, the new 20/1.4 uses the BR coating ('blue goo') like the EF 35L II and RF 85/1.2L to reduce CA.
I already have the RF 24/1.4L, this one is pretty close numerically but 20mm is noticeably wider in my experience, and also means an extra 4 trail-free seconds for stars.
Me too. And I can't justify having both. So I guess I sell the 24mm?Originally Posted by neuroanatomist
R6 II --- RF 14-35mm f/4L IS --- RF 24-105mm f/4L IS --- RF 70-200mm F4L IS --- RF 100-400mm F5.6-8 IS --- RF 24mm f/1.4L --- RF 600mm f/11
70D --- EF-S 10-22mm f/3.5-4.5 --- EF-S 17-55mm f/2.8 IS --- EF 70-200mm f/4L IS --- EF 85mm f/1.8
I'm considering it, but it seems a shame to sell a lens I bought so recently. I'll probably keep both and see which gets more use. The bigger question for me is do I really need to also keep the RF 24/1.8 STM?
