We are all aware that other factors like FL, distance to subject plays a part in DOF... Maybe hes trying to say that in a certain scenario where these factors are constrain, he "needs f2.8 for bokeh and DOF", then it makes sense. well strictly speaking, bigger aperture should only affect DOF, and not bokeh (as bokeh means the quality of the out of focus areas). Pls correct me if im wrong here, but that has been my understanding all along.
I want to say that, technology is beautiful and it can bring both good and bad. As someone has pointed out, digital has made learning photography possibly much faster/easier/cheaper. technolgy also made clubsnap possible where everyone can share and become a better photographer in 1 way or other. Im thankful that many experienced guys are sharing their knowledge and i myself have learnt a lot in this thread. Lets continue to learn from one another and be nice to all fellow Clubsnappers

afterall, we are all here for the same purpose to learn
