I currently have the standard USM version, but I am considering selling that this springtime and putting that money towards the L version of the lens. My question is, aside from the IS, is there a lot of difference? Is it worth the $400 or so to upgrade to the IS version? Any reasons I shouldn't upgrade?
Hi David!
There was a similar thread before. Maybe you'll find it. I don't have the time searching now.
I have owned the non-L and switched to the L version like you plan to do. I used both on FF not on APS-C bodies.
IQ:
Maybe you'll find some advantage for the L in test chart shooting, nut if you are not a total pixel peeping geek I'd say it has no effet in real life shooting. This was something I was a little bit disappointed about.
Built:
The L version id definetly better built and that "engineered plastic" is really tough.
And of course it has sealings that increase (but not to 100%) protection against water and dust.
I think Marsu42 posted about some bad experiences with the non-L.
IS:
That and the built quality was the main reason to me for switching.
You can do/try a lot shots handhold where otherwise a tripod was needed. (You still might need one in many cases)
Focus limiter:
The L has one with three instrad of two positions: 0.3-0.5m, 0.5-max, 0.3-max.
If you do a lot of macro you wouldn't want to miss the 0.3-0.5m which the non-L does not have.
If that's worth the extra money? For me it is.
