+1 10-22, 15-85 & 60 macro are the lenses I use most on my 7D - not cheap and in my view, on par optically with equivalant L glass. I just wish I could get these in L build quality - weathersealing would be nice. On a recent trip to Panama, the humidity [not rain] shut my 7D down for 3 days. I still wonder if that would have happened with sealed glass. Since Canon doesn't seem inclined to make such, I'm really looking at the OM-D, especially with the new 60mm macro if it turns out to be any good.My real question concerning C or H sensor is how many people on here are actually using a 7D with ef-s lens'? How many people spend that much on a camera, that much more for a 7D II upgrade and then puts $300 glass on it.I use mine a lot with the 17-55 and the 10-22 mm lenses, both of which admittedly did cost more than $300.
