4/3 has no focal length advantage-correct him if he is wrong

How large is his 100-400mm?

And is it as fast (f2.8-3.5)? If his lens is slower and larger, doesn't mean it's a bad lens, but bottom line is that the field of view is the same. If you are both standing the same distance and focusing on the face of a subject that fills his frame at 100mm; the same subject will fill your frame at 50mm. Same field of view, but you have a smaller faster lens to do it with. Similar effect (as far apparent closeness), but half the focal length. Seems like an advantage to me, but people view it through their own biases (just as I have here).

Cheerio,
Seth
