Panasonic 100-400mm vs others

That remains to be seen.

I actually expect the AF to be very good with the Panasonic but maybe not the greatest due to the slower aperture.....should be better than adapted similar lenses though yes.....at least for now anyway.

It does not ALWAYS follow that an adapted lens (with a smart adapter) is lesser than a native lens.....yes, most of the time it does but improvements in the last year have been rapid (even today there is a new firmware update for the Kipon AF adapter for EF lenses to M4/3 cameras).

You would only use these lens if, a, no option available, there is, or you already own one and didn't need another and were prepared to put up with the inconvenience!

Or if you don't like a particular quality of a lens (like bokeh), or if 6.3 is too slow and you might want 5.6 instead, or if the cost difference was greater than any other compromise difference (cost alone can be a big reason to choose one thing over another).....or if the other choice is good enough for ones needs/wants/uses.

Canon lenses now auto focus (some pretty much natively), IS lenses are stabilized ETC and some adapted lenses are little different to using native ones.....more so for manual focus but some AF lenses as well.

Weather sealing is something this lens will have in its favour....and again, form the few photos I have seen, I think it looks like it is a wonderful lens and maybe the best choice for image quality for its range on an M4/3 camera.

I would LIKE this new lens but wont buy it (cost, speed, only usable on M4/3) but would spring for a cheaper slower Vivitar 100-400 in EF mount as it would be about the price of postage for me for that new Panasonic lens from overseas, it can be adapted on several systems and it (might) be good enough....might be rubbish too but maybe worth a punt.

This new lens is a brilliant choice for many....others maybe not.
