I'm sure this question has been asked, but I can't find a good thread using the search engine, so if there is one please let me know. Otherwise...
How would you compare a Canon 70-200mm f/2.8L (USM, but non-IS) with a 2xTC to, say, the Canon 100-400 f/4.5-5.6L ?
I'm not a student, but I have an infant, so funds are very limited. Also the global economy just collapsed...
I have an EOS 40D with the kit lenses: 28-135mm and 18-55mm. My concerns are: Outside of birding the 70-200 f/2.8 has a million uses, whereas the 100-400 does not. The 70-200 f/4, a great lens, will not take a 2xTC for birding, and does not have the bokeh for non-birding portraiture.
All the birders want the 100-400 f/4.5-5.6L -- I get that. But, can I come very close to the IQ and speed of it with the 70-200mm f/2.8L with a 2x teleconverter attached? And if not, what are the limitations people have noticed? How is AF speed?
What would you do to build your photo kit if you didn't want to spend more than $1200US on your next purchase?
Thanks for the help.
