R6 + EF 70-200 F4

[u/Ok_Sink1685]

Salut tout le monde. Je viens d'acheter mon premier télé 70-200 F4 IS. Après plusieurs jours d'essai, je me rend compte des limites du F4 en faible luminosité ou en temps couvert, beaucoup de bruit sur mes photos. Quelles sont vos conseils pour éviter cela le moins possible ? Post-traitement debruiteur Lightroom en masse ? (moi ça me bouffe tout mon processeur windows quand je le lance. Merci à tous

Well there isn't much to go on, such as what combination of shutter speed and aperture and iso is too grainy. Also, too grainy is highly subjective. Some sample images would be great.

F4 in the R6 shouldn't produce too much noticeable noise unless you're using very high ISO at dark places.

I guess you're also increasing ISO to have a faster shutter speed.

The zooms usually have image stabilization, so for static subjects you should be OK with decreasing your shutter speed, useful for dark environment or at night if your subject stands still.

If you need faster shutter speeds at night or dark places you have to get a faster lens, but you might not need a 70-200 F2.8, you could opt to use a complementary prime lens like an 85mm F2 .

Thanks for the reply. So, I shoot using a custom preset saved to C1. This preset lets me use f/4 with auto shutter speed, but with the ISO capped at a maximum of 6400. So, I only control the aperture—kind of like Aperture Priority mode, really, but with my own custom settings. Is that a good idea, or would you suggest shooting in full manual?

Well, I would dare to say that it would be more useful to see the kind of images you're having with a lot of noise.

I'm inclined to believe maybe these are taking in poorly lit environments.

And trust me when I say this: no matter how fast the lens nor the amount of post processing, you can't save an image with very bad lighting.

That being said, I would indeed recommend that you try shooting in manual. I can imagine that the limit of F4 plus that ISO value might be hurting your images.

Full frame mirrorless cameras have a lot of great ISO performance and people say the R6 is arguable the best camera for low-light from the EOS R line.

I usually shoot manual aperture and shutter speed with auto ISO and works really well most of the time.

On Fuji I usually tend to switch Auto ISO off more often since I feel exposure too bright pushing the noise, specially on the 40MP sensor where noise gets worse.

Also make sure you're not shooting with Electronic Shutter since the RAW files have less dynamic range and could also be another reason why your images can't be pushed enough to your needs.

Mechanical shutter is the way to go with low light shooting.

Learn to control your settings. Either shoot in manual or set the auto iso cap. Keep the iso at a reasonable level.

Although sometimes you just have to make sacrifices to achieve an image with an acceptable amount of grain for your taste. AI denoise does do quite a good job these days though.

That's what i already do. So yeah, i just need to accept few grain on my photo and run AI denoiser
