. And The hybrid IS will shine on the standard zoom since it's wasted on real macro lenses like the 100L - the IS is nearly useless at very close distances..
Why is it wasted? Because you do not use it?
I was very skeptical of the hybrid IS on the 100L, but when I found I could handhold very close images with the lens, it is certainly a worthwhile feature.
1/40th second exposure @ f/8
Perfect answer. Your great picture is worth thousand words.
I still don't think so - and esp. posting a (downsized? cropped?) "good" shot doesn't mean anything. I could do the the same with old shots from my non-L macro - so what?
I'm using the IS all the time of course, but IS is all about *statistics* and a better keeper rate. If someone posts a picture and writes "just point and shoot with IS and this is what you get" this simply isn't true - you might have been very, very lucky, but in (my) real life IS raises the keeper rate esp. at medium range (like a full butterfly), but 1:1 handheld sharp shots @100% crop and lower exposure time still need a lot of exposures to get a good one. Coming from the 100 non-L, I don't see a significant improvement in these cases.
The one thing IS does help (except dual-use as a portrait lens) with is exactly what Canon states: IS on macro is for stable composing & setting the focus pane, not for getting much longer exposure times. So IS is not really "wasted" as I wrote above, but it doesn't magically axe your exposure time at macro distances, but it'll be great on the non-1:1 24-70/4:
In macro photography, shift camera shake and angle camera shake affect both the image formed on the sensor and the image shown in the viewfinder. This is especially relevant to handheld shooting at 1x, since the inability to properly compose and focus due to a shaky image in the viewfinder makes it extremely difficult to record sharp images.
