Question: Do you have any recommendation on tripod head for this lens?
Document: This lens is awesome when used on a tripod with a remote control shutter. No issues whatsoever. Obviously is for day time use as is not very fast. Very happy with the purchase.
This becomes a bit less true with the lens hood on it, but I haven't found it to be a problem. It is easy to handle, and on a tripod, I haven't found a need to use a lens mount. The system is so light weight, especially with my Panny GX-7, that it easily is held even with small flexible tripods.Image stabilization seems to work great.
A big splurge for a 15-year-retired guy. But here in the AZ high desert where photographic delights abound -- usually at some distance away -- this lens has inspired me to new heights -- or should I say new distances?. Love it! What I don't love that it is a slow lens (f/4.0-5.6). Tripod usually necessary.
This lens is totally capable of taking all sort of shots, but I was mostly surprised about the portrait shot capability. This lens gives very nice bokeh too. All shots are taken by handheld, although I know the shots will be a lot sharper if I used a tripod. Mega O.I.S works wonderfully to reduce the effect of handheld shot very nicely.
I shoot professionally , & bought a comprehensive Lumix kit for travelling , including the 100-300 lens. The lens is front heavy on a GX1/GF1. Would it have killed Panasonic to have built in a tripod collar ? I had to order one from germany. It makes a big difference in overall balance . The zoom operation is the worst I have ever experienced on any lens.
Wanting more zoom than my Panasonic 200mm gave me, I bought this Lumix 100-300mm lens. I haven't been disappointed with the clarity of the pictures taken with this lens. At full length, a tripod or steadying fence would be advisable, but I have taken many good pictures at 300mm hand held. Sometimes turning the lens to extend it feels a little stiff, but it's certainly not a problem.
This can be a VERY GOOD LENS! Given its VERY long 600mm-equivalent focal length (in 35mm full-frame terms), I suspect that much of the poor results seen in reviews and samples were due to poor technique while shooting with this lens. If used on a (sturdy!) tripod, I recommend using the electronic shutter instead of the mechanical shutter, at least a wired shutter release, and several tries for each photo.
I've been using this lens for eight months now shooting school concerts and athletic events. The lens has been mounted to an Olympus E-PL5.The good: Focuses well under bright light. Less hunting. Good contrast.The bad: Can be quite soft at 300mm. Lots of hunting under low light.Needs: A tripod mount.Would I buy it again? No. Think I'd rather have a fixed focal length lens instead but there's not much out there in the M4/3 world to choose from.
Great product, sharp. I use it with my Oly OM-D E-M5. Only complaint is that it does not have a  tripod collar which is really needed since effective focal length is 600mm.
Purchased this before a trip and I'm glad I got it. The zoom really lets you reach out and take close up shots of far away subjects. The image stabilization is also good, I was able to take early morning shots of the moon without a tripod. You do notice it on the front of your camera, however the weight is under 2 pounds.
Answer: You'll want to get this tripod collar for this lens:  http://www.roesch-feinmechanik.de/29701.html  And then any tripod head will work well.
