But when I want to zoom into 300 400 or 500, my photos are noisy beyond repair, even that reasonable, ISO levels and shutter speed. My photos seem to have movement due to low shutter speed, but I shoot at north of 4000 shutter speed on a tripod. In great light, still getting motion, blur and noisy images. in addition, it is incredibly difficult to focus onto simple objects. I tested this in my house with all my lights on, placed a medicine bottle, a continuously increasing distance, and the photos decreased in clarity exponentially as I zoomed in. i’m shooting on my relatively new Canon R8, with all settings, maximized for sports photography. Please help.</P><P>&nbsp;</P><P>#R8 #RF 100-500 F4.5-7.1 IS USM</P> Sun, 29 Dec 2024 14:00:58 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/Problems-at-longer-focal-lengths-with-my-NEW-rf-100-500mm-rf-f4/m-p/520917#M35645 connorb 2024-12-29T14:00:58Z https://community.usa.canon.com/t5/EF-RF-Lenses/Problems-at-longer-focal-lengths-with-my-NEW-rf-100-500mm-rf-f4/m-p/521358#M35667 <P>To help us get a better sense of what you are facing, I suggest that you attach an unedited image that demonstrates the issue.&nbsp;</P> Tue, 31 Dec 2024 14:00:55 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/Problems-at-longer-focal-lengths-with-my-NEW-rf-100-500mm-rf-f4/m-p/521358#M35667 Nick2020 2024-12-31T14:00:55Z https://community.usa.canon.com/t5/EF-RF-Lenses/Problems-at-longer-focal-lengths-with-my-NEW-rf-100-500mm-rf-f4/m-p/521374#M35673 <P>Absolutely post a sample(s) of what you are seeing and either leave the exif intact or give exact shooting details.</P> <P>Using a telephoto lens is more than just fast SS and low ISO.</P> Tue, 31 Dec 2024 15:39:08 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/Problems-at-longer-focal-lengths-with-my-NEW-rf-100-500mm-rf-f4/m-p/521374#M35673 ebiggs1 2024-12-31T15:39:08Z https://community.usa.canon.com/t5/EF-RF-Lenses/Problems-at-longer-focal-lengths-with-my-NEW-rf-100-500mm-rf-f4/m-p/521560#M35692 <LI-SPOILER>&nbsp;</LI-SPOILER><P>Share some examples of your shots with the EXIF data intact or include the specific shooting details.</P><P>When using a telephoto lens, it's not just about having a fast shutter speed and low ISO.
