Its just a simple situation of ending up carrying several bodies and lenses. Since I've been shooting a lot more with the G1, I carry it plus lenses. Then--often for any shooting that will be mostly landscapes, I usually carry the 5D also with the lenses I prefer for it. The 10DIR is a 6MP older tech camera--still great shots with it but its not as pleasing to handle--and I find that after years of piddling with IR I just don't have as much interest in it except very sporadically so I hate to carry that 3rd camera along (and I've found that it seems to like particularly a lens I never use with the 5D--the 28-135 IS LOL).Hi Di
I would ask why you have an IR converted camera and don't use it much?
