Well, you've all certainly made your points (thanks for that!) and in a way even made it harder for me. I'm now definitely looking at better but second hand glass (only way for me to stray from the likes of the 18-135 nano usm type lenses), but that decision has made it harder to choose a camera body. I'm considering the 6d1 second hand or the 7d2 or 80D... The comments on the AF system on the 6 makes me a bit weary of it. But it does have the advantage of FF and being considerably more expensive then the 7D(2) I would expect it to be better in many ways. But that is not always the case as I read. I may not do sports a lot, but I do like getting shots of our dog chasing around anything that strikes his fancy. Also kids move quick too... even though at 11 and 13 they will listen if I ask them for a pose. But I like the more unexpected shots a lot of the time.
But seeing that the better glass brings one mostly to the EF range of lenses this really has me wondering if I should go FF. And if I don't what would be a good entry level lens. I mean a 24-105 on a crop camera is almost a 40mm. That is pretty far of from the 18 (28mm ff equivalent) I am used to now. Another consideration on the better glass is that the lenses I seem to be recommended often have F4 as wides opening. Will that do well enough in portraits? I can always ad the 85mm 1.8 off course but I cannot justify buying a body and three lenses at the same time so would like to give myself a decent allround start.
