So, I have been trying to do some candid photography in indoor events like birthday parties, get togethers', etc. I have always had issues either with blur, under exposed pictures (because I tend to use fast shutter speed to capture the moment). Then I added faster lenses (f/2.8) initially, a tripod little later, and a hot shoe flash a little later(I prefer not to use it as it attracts the subject's attention). I definitely started seeing some improvement but my pictures are still blurred or are still under exposed - meaning not up to the mark. The only thing left for me to do is to push the ISO & as I did, the pictures started becoming very grainy/noisy. Now, I am starting to think if it's time for me to upgrade my Canon T5i to maybe a Canon 5D Mark IV?
If I have to upgrade to a high ISO body, should it be the Canon 6D or the Canon 5D Mark IV? Which of these is a good value for money body in the long run? Is the $1900 difference worth the 5D IV?
