Well i took this photos a while back with that lens.
I cropped the edges. Same crop factor.
Here's one i took 2 days ago.
There's just one more lens i wanna get. Canon EF 16-35L. And that's pretty much it. After that, i'll just go for full frame (5D replacement) if i really want wider than 16mm.
For the 24-105L, you can actually hear the Image Stabiliser working. It sounds like a whispering steel wheel turning. And i love how fast the auto-focus is. Can't see any significant soft edges in f/4. Maybe i got a lucky copy.
The weird thing is, the lens is heavier than the body. Which means when you grip it with your right hand only, you have to grip is even more righter because the lens is heavy...which makes you shoot like an unco.
P.S: I love RAW! I shoot 98% in RAW. Just so convenient for post-processing.
