Panasonic Lumix G9 (1 Viewer)

Any 600mm lenses to fit the G9? Looking for some extra reach, my 100-400mm zoom is very good but I'm chasing some shots of birds that are hard to get close to!

That would be 1200mm equivalent, I tend to just crop at that distance as you’ll never get a stellar shot without superb glass at that size. I guess adapting Canon glass or the Oly 300 with a 2x TC would be the best options currently. The new 100-400 PL accepts TCs as you may know, a 1.4 TC will get you native 560mm, but a 2x might be pushing it, I look forward to seeing some results when it is out.

I am tempted by the G9 ii for a little extra cropping power.

This one has a built in 1.25x TC, making it effectively a 500 mm lens:

Otherwise using one of the lens adapters you can add something like the 150-600 lenses from sigma or tamron. I have no idea how the image quality or the AF would work using such a combo.

Of course, in some situations it would be possible to "zoom using your feet" or in other words get closer.

I agree the new PL100-400 ii with a TC is probably your best bet without spending a ton of money. Image quality is going to suffer because you will likely run out of light and have to push ISO, also getting into diffraction territory with high f numbers. Any optical imperfections will also be magnified with a TC. That said, the images may still serve your needs.

If 600 mm is precisely what you want, then the oly 300 mm f4 prime + 2X teleconverter mentioned by Essex Tern would seem to be what you are looking for. People on the DP Review forums get some impressive results with this combination. (Though personally I have struggled to get the same results – I'm not sure why).

He is using the Olympus 100-400 with TCs and he lists pros and cons. It should be pretty similar to using the PL 100-400 with a TC. One thing I would say is that he is pretty close to his subjects for the sample photos. A bird 50m away will not yield such nice results, so temper your expectations.
