I'm using EOS R5 for half year now. I'm using EF and EF/S lenses, because I spent too much on camera body and can't afford to acquire better RF lenses yet. I'm unable to get good photos without visible noise at low light or bad lit situations, when viewing photos at 100% zoom.
Settings: 1/800 | ISO 5000 | F5.6 Captured with EF 70-300 F4-F5.6 This image at 100% is unusable. Noise is too visible. It was captured at the stadium with not perfect lighting conditions. This kind of image was ok for local media where images are compressed from 40mb to 100kb, but for me at 100% noise was too much visible. 25% Luminance in Lightroom is applied.
Settings: 1/800 | ISO 5000 | F5.6 Captured with EF 70-300 F4-F5.6 Same example as above picture. Image was shot at same settings as above picture. When crop or zoom-in image becomes unusable because of grain amount.
Settings: 1/320 | ISO 6400 | F5.6 Captured with EF 70-300 F4-F5.6 Better lightning condition, makes noise almoust disappear. Noise is not visible that much at good lightning.
Should I get better prime lenses or should I save money for high quality RF lenses to get better performance?
