Camera Upgrade Recos: Grainy, blurry photos from current EOS Rebel T3i

[T8rsmom]

Hello! I am looking for some advice on upgrading to a new camera. I am a novice who likes to take sports (baseball/basketball) photos for my son, pics of family vacations. I currently have a Canon T3i but I am not satisfied with the quality of the image. Everything looks grainy or out of focus. I do use manual. What would be the next camera up from the T3i? Should I look at mirrorless? Any help/advice  would be greatly appreciated. 

Thank you.

Thank you for your advice. I will definitely look into the R100 or R8.

Any specific lens I should look at?

With your current lenses I wouldn’t recommend moving to Full Frame. It would be best to sell all of your lenses. Then replace them with Full Frame RF Mount lenses. If you decide to move to Full Frame. There will be a great reduction in megapixels by using APS-C lenses on Full Frame cameras. In Full Frame mode the EOS R8 is 24 megapixels. But in APS-C mode it’s only 9.4 megapixels. Which is much less than your current camera.

Thanks. I would be okay with spending up to 1500 since I would have to get new lenses.

Look into the EOS R10 which is within your budget or EOS R7. You can use your current lenses adapted. But I would still recommend selling the 75-300mm lens it’s too slow. The aperture and AF motor. The 18-55mm can also be sold off. The 17-55mm is a much better lens. You can use that money to put to either of those bodies and a better telephoto lens. Also a mount adapter for the 17-55mm. The EOS R7 lacks a built in flash. Like all of the Full Frame cameras do. If a flash is required you must use an external speedlite/ flash.
