The 75-300 Oly is much slower than 100-300, take my word for it…I have owned and shot both extensively…the 75-300 cannot focus many times when the 100-300 can…the extra light the 100-300 allows is worth it in AF speed and Shutter Speed and it is still a challenge at times with EM5 as they fudged the ISO and the Shutter Speeds are slower than other cameras at equal ISO values, so for Birding and Nature you WILL need the fastest glass you can get on the EM5...

Moving Subject + EM5 + f/6.3 = Blurred photo...

YMMV...

Mr Ichiro Kitao, I support the call to upgrade the FZ50.
I will not only buy one but two no questions asked...

Too many wrong facts.

Basically, everything about the OM-D fudging ISO is wrong. THE OM-D uses the same shutter speeds (within 1/3 of a stop) as other cameras for any particular camera ISO value, as expected.

For more info, check out the rather long debate here:

As for focussing, I suspect that's wrong too. Most reports say the 75-300 is faster at focussing.
