Replace my 24-70f/2.8L II with a faster 35f/1.4L II? Prime speed and IQ vs zoom versatility

Hi,

I shoot kids, family and friends indoors and outdoors. My family love to travel, documenting our trips is a big part om my hobby photography.

• I use a Canon 6D and 3 lenses:
• 50% usage 24-70f/2.8L II used at: First 35mm, secondly 24mm, thirdly 70mm.
• 40% usage 70-200f/4L IS used at: First 200mm, secondly 70mm, thirdly 85mm.
• 10% usage 16-35f/4L IS used at: First 16mm, secondly 20mm, thirdly 24mm.

I use my 24-70f/2.8L II a lot, often wide open and mostly at 35mm or longer for people photography. I often wish for a faster 35mm lens for stopping kids aktion, even better IQ, bokeh and for low light outdoors.

I have already decided to upgrade my 70-200f/4L IS to the faster 70-200f/2.8L IS II. As 35mm is my most used focal length, replacing my 24-70f/2.8L II with a faster 35mm is what I plan to do before our next trip to Amsterdam this fall.

1. To all here that own 35f/2 IS and 35f/1.4L II or have used both. Comparing image quality, resolution, contrast, ca, coma, rendering and bokeh. How do you rate 35f/2 IS vs 35f/1.4L II on FF used wide open?
2. If you also own or have used a 24-70f/2.8L II. How do 35f/2 IS and 35f/1.4L II compare to 24-70f/2.8L II used wide open at 35mm?

Best regards

Another option: Keep the 24-70, upgrade your 70-200 to the f/2.8L IS II, and buy the 35mm f/1.4L II. This would mean selling your least used lens (16-35). Just my $0.02, but I rarely shoot wider than 24mm.

I can't compare the 35mm f/1.4L II to the f/2, since I've never used the f/2. However, I own the new f/1.4L II, and that has some next level quality! Awesome environmental portrait lens. The 24-70 is an amazing lens (as you know), and is probably the the most versitile lens I own. If I drive to the mountains with my kids, or into the city, I can take the 24-70 ONLY and get great images all day long. It is for the more specialty stuff (portraits, weddings, etc.) where the 35mm and 70-200 really shine (though the 24-70 is no slouch there either)! The only other lens I still want is the 50mm f/1.2L, and I'll be set!!
