Hello. What I’m about to say here will probably sound a bit vague at times but here goes. I use the R5 and I have three RF lenses: 14-35 f/4; 24-105 f/4; 70-200 f/4. Images used with the 14-35 f/4 and 70-200 f/4 are ALWAYS tack sharp. However, images using the 24-105 f/4 aren’t always sharp, even when I’m shooting the exact same subject with the exact same camera settings as with the other two lenses. Sometimes 4 frames taken immediately one after the other won’t be sharp. I’m shooting at high shutter speeds so I doubt it’s camera shake or subject movement, especially since I get excellent results using the other two lenses under the same conditions. I will say that when the images are sharp using this 24-105 f/4 lens they tack sharp, but they aren’t always sharp. Whenever I have camera issues I will immediately think that it’s due to user error (i.e. me), and it usually is. This “some images aren’t sharp” issue I’m having with the 24-105 f/4 is probably also due to something I’m doing but I can’t figure it out. I’ve taken the body and lens to Canon, they tested it, and they said all is good, so it must be my technique. This “non-sharp” issue happens about 3% of the time. I know this is vague but can anyone out there suggest some tests or steps I might try to figure this out? It’s really bothering me because when I’m shooting an assignment and using this lens I don’t feel confident. Thanks for any help or suggestions.
Hello Johnsey, thanks for your reply. Actually, it's probably about 5%-10% inconsistent that I get non-sharp images. I think it has to be either my focus point setting or the subject matter (or both) which at times can be horizontal/vertical lines which Canon has admitted can be challenging for their cameras to focus on. I'll try a few more tests and see if I can figure this out. Will keep you posted. If you have any ideas let me know! Thx -
Are you using servo to track a moving object? It can introduce focus problems when used when you do not need it.
So many youtubers jumped on the "WHy tHe EOsR iS deh WorSt Cam of 2018 CROPPEDED 4K NO BEPIS or Dual CaRd Sloot" bandwagon for views and put a lot of amateurs off The EOS R's adapter allows you to use EFS lenses and guess what? They work amazing in 4k because they are designed for cropped sensors so you can put a 10-18mm IS and get the same experience as a full frame 17-25, I typically use the 15-85 efs lens which acts like a 22-92 ish ff lens
