Bottom line the canon 24 105mm f 4 l is a really excellent optic but one that struggles a bit along the edges and in the corners with full frame bodies.
Canon 24 105 full frame review.
Neither this nor the original 24 105 is zoom very easily.
It is usefully wide at 24mm.
The canon rf 24 105mm f4 7 1 is stm is impressively small and light considering the versatile focal range that it covers weighing in at 395g and measuring 8 88cm in length although it does extend by an extra 5 7cm when the lens is set to 105mm.
It also weighs 95 grams less at 700 g versus 795 g.
Compared to the canon ef 24 105mm f 4l is usm ii the mirrorless version shares an identical diameter but it is 10 7 mm shorter.
It s the easiest to zoom has the most even zoom spacing between focal lengths has the best macro performance less distortion and is just as sharp.
As such it s an almost ideal candidate.
And the 24 105 l lens hood is much smaller as can be seen in the picture below.
Measuring 83 5 mm in diameter and 107 3 mm in length at the 24mm setting the rf 24 105mm f 4 is relatively compact for a full frame zoom lens.
