These three are my most used lenses.Not so fast, the 24-105 is a great range, albeit at f4. However in studio shoots, one is usually at F5.6, 8 or narrower... and the zoom range of the 24-105 comes in handy to provide the portrait range of 80-100. 24-70 is a great lens but don;t give up so fast on that 24-105.. plus it has IS!!!
70-200 f/2.8 II
I will purchase a 24-70 f/2.8 II soon and expect that lens to replace the 24-105 on this list.
You might be right. Once I get the 24-70 I'll be able to answer better. I just imagine I'll be using it for most shots between 24-70mm thanks to its superior sharpness and less distortion, but might miss the range and IS. I plan to hang onto the 24-105.
