Take this lens for a holiday trip with some hesitation. It used to be my trusty 24-105L.
No regret. It on my 5dmk3 99% ! The other 1% is the cute little 40mm STM.
Carry it entire day - ok
No IS - ok, minimum shutter at 1/125.
Only 70mm, not 105mm - ok. Just crop a little.
No Flash - with iso 12800 - Ok, probably need it for 24-105L unless I push Iso to 25600.
Video - ok, only take 2 short clips anyway.
24mm - ok, not a hardcore landscape shooter.
MFD - ok, able to shoot inside a cable car/Ferris wheel/monorail.
Color - wonderful !
Bokeh - wonderful !
Contrast - wonderful !
Sharpness - wonderful !
Dof - great subject isolation
Kids running towards me - ok, burst with servo.
AF - fast, accurate with consistency !
Weight distribution - very even. Lens and body feel as "one".
Size - feel like a 24-105L.
