EOS R6 Mark II Lens recommendations for events and studio work

[okanho2]

I have an R6 II and an RF 100-400 f5.6-8. I want to add one more lens because I also want to shoot events and studio-based work. So I have a confusion about what I should buy. I have options like the RF 24-105 f4, 28-70 f2.8 STM, or buying primes like 35mm 1.8 or 85mm f2. I'm looking for a sharp image and value for money.

What is your budget a prime is more limiting than zoom lens. Is low light a concern of yours or not. Both zoom lenses already cover the 35mm focal length. The 28-70mm F/2.8 STM would be a better choice. The slower the lens aperture the slower the AF system becomes. It will slow down to the point that the camera cannot lock focus. Are you going be using a flash if permitted.

okanho, welcome to the site. 

You mentioned you would like a lens to shoot events and studio-based work which can be very different settings. I single lens can fulfill these but a fixed lens may not be the best solution. I'm sure others will stop by this thread but additional information would be helpful. For the studio work, will you be using studio lighting? Are you going to be shooting portraiture in studio. The events, will they be indoors, outdoors or both.

Personally either way I would opt for lenses that are faster, at least f2.8. If I can afford it I prefer adding faster lenses as they are more versatile.  One stop can make difference in having to increase your ISO, noise is not always your friend and creates the need for post production.
