Telephoto Lens that can keep up with my G7?

I purchased a Lumix G7 around 3 months ago. Can't be happier with it, it's a fantastic camera.

The first thing I did was ditch the Panasonic 14-42 that came with it. Theyre a poor lens optically. I replaced it with the older 14-45 which is a much better lens optically. The problem with the 14-45 is that being an older lens, it struggles to keep up with the G7 when shooting bursts of images. As the camera will only fire (due to my required settings) once it has achieved focus, rather than the 7fps it is capable of with more modern lenses (like the 14-42, it drops down to around 3fps and has the super high speed mode totally greyed out.

Try getting a VERY fast memory card. You'd be amazed how performance improves overall, from startup time to saving image files. I just picked up a Lexar 2000x (300MB/s) memory card and my GX8 does everything MUCH faster.

Be sure to reformat your memory cards occasionally, instead of just dumping images.

Now for general use, this doesn't bother me all that much. I generally shoot in AF-S mode so burst rates don't even come in to question, however, I'm looking to buy a telephoto lens for which I will be shooting moving subjects where a fast burst mode will be very useful. 3fps would be ok, but making full use of the G7s capabilities would be better.

I've been looking at used lenses and the 45-200 and 45-150 are the lenses that catch my eye. The 45-200 being the older lens out of the two, but also (apparently) being the better lens optically, which is very important to me. I have no doubt that the newer 45-150 will perform better with the G7 body (AF wise) but has anyone used a 45-200 on a G7 or more modern body? How capable was the lens in burst mode (at being able to acquire focus between shots at high FPS). Likewise for the 45-150. Is it any better?

You've got it backwards. The 45-150mm is better optically and it's much smaller, lighter and the autofocus is much faster.

For a single lens solution, check out the 14-140mm II.
