Camera or lens....

For action shots my 7D is my choice, even over my 5D MRKIII using the same lens. The 7D's focus tracking is excellent, and not to far out of reach cost wise for most people. Just my view of the 7D...

As to the original question I think you answered it in the first sentance. "just started shooting","lack of experiance'. You have good equipment. If you want a new camera or lens great but don't expect them to fix the problem only time and practice will do that.

I cut my teeth shooting aussie football games on a manual camera with 400ISO B&W film...... then back to the office to process the film and develop the photos myself.
But there's no way I'd go back to those days. It was most definitely a lot more difficult than today.

Well, fact is you need to LEARN how to use the Autofocus system.
If you use it in the wrong way, there will be less keepers.

I used to photograph motor racing with my Nikon F cameras. These are film cameras and I did not have a motorized film advance. Auto focus did not exist in those days. I had absolutely no problem making a series of shots in rapid succession while advancing the film manually between shots AND changing the focus between shots while following the action with the camera.

Every other sports photographer in the day had roughly the same type of equipment available and I don't recall a shortage of good sports photographs being published.

In other words, I would not blame the camera for not being up to the job.

I said in the beginning that some of the OOF shoots I get are due to my lack of experience, so all the "back in the day we shoot amazing photos with a disposable camera" is'nt really necessary

Aside from that I'm starting to lean towards the 5d3 as I rather have 1 body
and a lot of people told me it'll be better then the 7d, I can even use a 1.4 teleconvertor
to match the 7d reach and the better ISO capabilities of the 5d3 will make up for the loss of 1 stop of light

Thank you all for your comments! they are very much appreciated

My Nikon F cameras (which I still have, by the way) are far from "disposable cameras". The point I was making is that they (and most other SLR cameras from the mid 1960s) are totally manually operated film cameras. The photographer using them has to choose the film (both type of film and ASA speed - similar to today's ISO values), advance the film manually for each frame, set the aperture and shutter speed based on a light meter and/or experience for exposure control, and manually focus the lens for each shot.

I understand all of that, my dad is an events shooter and used the Nikon F cameras back in the day but now he got a 5d3 and it makes photographing EASIER
I'm not a full time pro most of what I photograph is unpaid so I just want a "tool" that will make taking a sport photos easier even thou I know I will get better regardless
P.S I'm going to buy it in a few month anyway because I need to save up
