Recommendations on a lens ...

I've got following lenses:


24-105 f4 IS USM, 24-70 f2.8 USM, 70-200 f4 IS USM and 70-200 f2.8 IS USM etc...., my suggestion buy all above :P all great lenses ! All for different use~ If you onlycan getone lens for FF body, 24-105 f4 IS USM will do. For 1.6x body and not thinking upgrade FF body in the future, I will get EF-S 17-55 f2.8 IS USM.


Just wanna mention 24-105 f4 IS USM to stop action indoor may require high ISO up to 800~1600 with speed 1/250 or 1/320~


Buying lenses just never end story~~

I'd go with


3) EF 24-105 4L - great length but maybe too slow for my kid when indoors


...in conjunction with your flash, you should be good - maybe get a Gary Fong slip on to soften the flash. This lens is great with a decent reach and nice Bokeh. If you wish I can submit some photos to you for you to compare that I have taken in low lightusing flash.


Hope this helps...

24-105 is what I would recommend. its very sharp, and a great lense all around
