I got to try this lens for about three months in 2023 as a lifestyle and portrait photographer.
Was 99% sure I'd bite the bullet and get this in 2024 to partially replace my EF 35 and 85 1.4s but the weight and size have always just been the largest dealbreaker. It also doesn't help that it has quite bad focus breathing which makes filming video on it quite challenging, to say the least.
However, in my experience, the IQ in a zoom package was just unbeatable and made it worth the squeeze. Now the biggest dilemma is does one hold off on buying the current 28-70 in the hopes of an updated version within a year or just buy it anyway- deal with the cons and probably sell it at a significant loss when the improved V2 comes out?
