Who here has upgraded from the 24-105 to the 24-70 ii? What are your thoughts and was it worth the change?
I have extensive experience with my 24-105. It's my favorite landscape lens and have shot with it for years. Always been a touch soft in my opinion, but nothing I could not get past in post.
I don't care about IS. This is a pretty short lens and most of my shooting with it is tripod mount.
If you shoot on a tripod then hands down the 24-70 II! I tried the 24-105 a few times and sold or returned each on within a week, never liked 'em. Not so hot near the wide end on FF (not even as sharp as my, back then, FAR less expensive Tamron 28-75). The 24-70 II also has more precise AF for one shot mode if used with a 5D3 or 1DX, although for tripod work that doesn't matter.
Let me put it this way I got the 24 1.4 II because I couldn't find anything else that gave a decent 24mm on FF (back then). That was way better than the 24-105L at 24mm. But my 24-70 II is so close to the 24 1.4 II! It actually even has LESS longitudinal CA and thus less purple fringing and stuff of branches against clouds and such than the 24 1.4 II, never mind compared to the 24-105. I sold my 24 1.4 II!
24-70 II is way sharper and has less longitudinal CA and better AF and less distortion and even better contrast and it's not even really any larger (although I guess a bit heavier). The price is a bit fierce though and there is more copy to copy variation than you'd like for a lens that price (even a below average one is still easily way better than the best 24-105 though).
If you can handle the price and don't mind spending that much money and have no need for IS then yeah heck yeah it's way worth the upgrade. Nobody makes a better 24-70, certainly the Nikon doesn't keep up.
24-70 II + 70-300L makes a totally killer landscape pairing (the 70-300L is another lens that nobody else does better) and add in a 24 T&S II if you really want the ultimate landscape trio (and the 17 T&S and samyang 14mm to go totally crazy
). I have the 24-70 II, 70-300L, samyang 14mm. One day I wouldn't mind adding the 24 T&S II.
