I am interested in a M4/3 system for photography which requires more magnification i.e. macro and birds/reptiles. Both the 300 and 100-400 allow quite close focusing which would important use of these lenses for me but I have not seen any comparison at the closest range. Otherwise I would tend to the 300.

Also I have not made any decision on which camera: GX8 or PenF. Panasonic uses the same batteries as my Leica Q and I like the tiltable viewfinder but I am concerned losing the advantage of IBIS working with Olympus lenses.

We are thinking the same thing Pd printer.

The 6 stop sync IS available with the 300 and EM5 II seems very desirable.

Another feature we like in the 100-400 is the 72mm filter size which would allow us to use the filters we already have for the 40-150 Pro.

I guess we're like everyone else; we wish the Oly and Panny stabilizer systems were fully cross compatible.

Both the 300 and 100-400 have advantages and disadvantages, but I'm glad they are here!

The thing with the Olympus 300mm f4 price is for less cost you could get a nikon dslr, tc and their image stabilised 300mm f4 and have a bigger sensor so Imo it's a no brainer and there's little difference in size and weight so why spend all that on a lens??? To me Olympus have shot themselves in the foot with that one.over 2k for a not very versatile lens is ridiculous.

Petebuster:

Are you referring to the Nikkor 300 F4 made for full frame?  I'll look into it - saw a price of $1995.00 on it but need to know more.

And, thanks for your response.
