EOS RP photo aren't as sharp the ones from my EOS M50

Hey i realized that a lot of my RP photos arent as sharp as my M50 at further distances and a lot of times my RP photos are blurry and i never experienced the same with my M50.

The picture at the pier was with RF lenses and as you can see it cannot focus well at all. The other pictures are with a EF 50mm. The clarity of the walking person in with the m50 is just far higher than the people in the RP photo. Please take a look and see if you agree. (zooming in makes the biggest difference.)

The picture with the pier the camera did focus on something. It didn't focus on the people you would have to zoom in more to get them in focus. A camera can only focus on one spot not multiple. Using a different F/ stop for instance moving from F/4 to F/11 would yield more things in the background to be in focus. The camera will always focus on something that is closer to it than further away. Also if it has more contrast it will do the same thing.

I did singular point on a building and even that building came out blurry, im going to see if i can take more photos as examples tomorrow.

I think that is a good idea.  Can you humor us by taking some using the LCD and some using the EVF with the hand and arm placement as shown?  Technique is far easier and cheaper to fix than gear issues.

1. What AF Zones are you using?
2. What focus mode are you using One Shot, Servo AF or AI Focus?
3. What mode is the top mode dial set to?

[Tronhard]

From looking at DPP4, the mode is M, low speed continuous, Servo

One Shot would be a better in this situation vs Servo AF. The subjects are stationary and not moving.

To add to the comments that Demetrius has made about focus - using the default matrix focus will simply let the camera focus on what has the clearest contrast and what is closest.  In a cluttered image it is much more effective to use single point or expanded centre focus.  That way you point the centre of the field of view at the point you want in focus and the camera will concentrate on that.  However, the challenge then if you are using the shutter button to focus, moving the camera to compose may well get the focus point to move.  That is why so many photographers use Back Button focus, with centred spot focus and Servo.

See the following video from Canon on this subject:

Another thing I am picking up is that the images from the RP are generally blurrier than those of the M50, but looking at the details in DPP4 at how the images were shot, it appears you are shooting in live view mode, is that correct - i.e. you are shooting by looking at the back LCD rather than via the EVF?

[kingsahibkhan]

Yes i use the LCD more often, and i did the same for the M50. I generally do not have camera movement issues if shooting faster than 1/80 on the shutter. The focus issue with the RP comes up even when the focus is on singular point and focuses right on the subject. I usually delete all the bad photos so i dont have an example to show you but its a constant focus issue when shooting at a distance.

On the m50 if i used the 50mm and singular point focus to shoot a subject thats 10 meters away there are no issues with the sharpness of the subject but if i do the same with the RP it does not focus well and become blurry.

My examination of the images in DPP4 and Photoshop really show that there is consistent camera movement - it's not just my opinion, I consulted with Demetrius and he shares the same opinion.  You definitely have camera shake as well as some focusing issues, so it's up to you if you want to take the advice about using the EVF.

One sees a lot of images on social media and You Tube of people shooting via the LCD, but usually they are shooting with cameras using very short FL lenses and they are using lenses with image stabilization, and many cameras have IBIS as well, to mitigate that camera shake. Your 50mm has no IS and its own weight is exacerbated by the EF-RF adapter required, apart from the weight of the camera itself.  With the RF 24-105, while it has IS (is it enabled?) that is not a guarantee of steadiness with shooting - that IS is designed assuming one is holding it as steadily as possible, it's not a panacea.

As to the focus itself, I would definitely suggest exploring the use of the more limited focus points - this gives you the most control of what the camera is going to focus on.  Most fellow professionals I know will use single point focus and BBF to control.
