I have been using my 28-135mm f/3.5-5.6 IS USM Kit lens on my 7D here in Iraq with favorable results. It's very versitile. I can shoot events, sports, portraits, group photos, zooms and even macro.
Using a camera bag isn't really feasible most time for most of the shots I need to do, neither is using a tripod.
My compaint is that its a bit soft. I also have to to keep the white balance and ISO up if I expect to get a good shot indoors.
I have the budget to upgrade to a very nice L type lens. I have solid budget of atleast 2500 for 1 or 2 lenes. It would be nice to get something that will really add to the type of shots I can get considering I'll probably still keep this lens.
A few I am considering 28-300 3.5L IS USM, 70-200MML 2.8 IS USM, 10-22MM F3.5, 100-400MM L., 50MM 1.4 SIGMA.
NewB stuck here in Iraq. Can u give me some suggestions?
