Wow, so first topic in the forum!
So here is my question... I currently have a Canon 7D Mark I, but thinking of down/upgrading to the 70D because of its better video capabilities, WiFi, movable screen, etc.
In order to do that and not invest money (I would buy the 70D new), I would have to sell both my 7D and my 24-105mm f4 L lens. I would then buy a new 70D with a new 18-135mm f3.5-5.6.
And my question is: is the 18-135mm really noticably less sharp than the 24-105mm f4?
I use it as my "always on" lens and for travel. The 18mm vs. 24mm is a nice improvement for me as well as the slight increase in tele-zoom. But those are just little things that would not be worth it, if the cheaper lens gives me bad photos compared to the more expensive one. I mean, some decrease in quality must be expected - there is a reason why the L lenses are more expensive. But for a hobby photog like me, is it really a point?
Apart from vacations I usually do outdoor portraits and stuff like that and for that I tend to switch to my 50mm f1.8 STM because it is sharper than the L-lens anyway.
