Does anyone have experience with these two lenses? In particular, the IS on both. I'm interested in buying a new 24-something lens for full frame purposes. Also how would these lenses compare with the 17-55 in terms of IQ? Anyone got sample images of the new 24-70 f/4L?
I've had a play about with both lenses. The 24-105L has the advantage of being almost half the price. But is it a mistake to go from a 17-55 to 24-105? Image stabilization is more important than wider apertures so for now the 24-70II is out.
Not a fan of Tamron so that's out too.
Even my old Tamron 28-75 had better edges on the wide side than the 24-105Ls I've tried on FF (and crisper in the center too, not that the 24-105 was soft in the center, just not quite as insanley crisp). So I actually tend to like Tamron. My 17-50 2.8 from them was also amazing. I sold my 17-40L.
Anyway I have not personally tried the 24-70 f/4 IS though.
I can say that the canon 17-55 IS delivers crisper edges and corners on APS-C on the wide end than the 24-105L does on FF. The 24-70 II manages to get you the same crisp edges though on FF.
Supposedly the 24-70 VC and 24-70 f/4 IS fall somewhere between the 24-105 and the 24-70 II, perhaps closer to the 24-70 II. But I've never personally tried the tamron 24-70 VC or canon 24-70 f/4 IS.
I was so excited when my 24-105L arrived.... and then I tried it.
And then I tried another and another just to be sure.
They just didn't do it for me on FF. It depends how much you are about the 24-30mm range and whether you demand edge to edge fine details for certain types of landscape work or not. Some people shoot mostly subjects falling mid frame even at the wide end and don't even know what all the complaints are about (that said my tamron was still a bit sharper even center frame, but as I said, the 24-105 was hardly soft there just not completely insanely sharp and it may have had a touch richer color). I always thought the 24-105 had some of the most avg IQ of any recent L lens.
Of course you can manage to nab the 24-105L for like $600-650 sometimes even now with so many kits being split or so many amazing body kit deals, at the old $1200 or $1000 or even $800 it seemed a bit steep for optics although very convenient, but at $650 that is quite the deal though. The 24-70 f/4 IS does seem to be arguably the most over-priced of the whole lot at this point, although the 24-70 II sure ain't cheap.
