Hi,

Based on real-world use, can the RF 28-70mm f/2L match the RF 50mm f/1.2L in terms of sharpness, contrast, etc, at f/2? A high-quality zoom that can replace primes seems attractive. The RF 24-70mm f/2.8L looks to be a good option, albeit that it's slower and possibly rougher in the corners.

I tend to shoot at f/2 or narrower with my R5, but the f/1.2 performance of my RF 50mm may be missed.

Thanks

Nothing performs as well as the RF 50 f/1.2 at f/2 except the RF 85 f/1.2. The RF 28-70 at 50mm and f/2 is probably 90% of the sharpness and 100% of the color from the RF 50 f/1.2.

Also don't underestimate the weight and size of the 28-70. For the most part, it can replace primes in 28/35/50/70, however, it will feel like you have all four of those lenses on your camera or in your bag at the same time, so the only gain is the convenience of not having to change lenses and/or reacting to conditions with the zoom. If you shoot events, the 28-70 is quite valuable, for landscape maybe not as much when the RF 24-105 at f/5.6 or f/8 will be the same or better.

Thanks for the reply. The weight is a factor as it's unlikely I'll want to carry it around all day on holiday. I have 35mm f/1.4II, RF 50mm f/1.2L, RF 24-70 f/2.8 and RF 70-200 f/2.8L so the plan would be to sell the 24-70 and 50mm to get the 28-70. I love the 35mm f/1.4L II which I'd only replace with an RF L version. I'll rent the 28-70 to see if the weight is tolerable.
