1 OIS is a relatively affordable new tele-zoom for L-mount cameras. We've borrowed a sample and had an opportunity to shoot a handful of samples with it at the local nature reserve.
Sadly there weren't many interesting birds around and the time we were able to visit, so we've ended up mainly with pictures of our favorite fallback waterfowl: ducks. There was a Belted Kingfisher, surveying the scene, but he seemed determined to only perch too far away to be photographed, even with the 1000mm reach of the new lens and a 2. 0x teleconverter.
At 1285g, excluding the tripod foot, we found the 100-500mm to be pretty easy to hand-hold, and we probably would have been better off leaving the tripod foot at home. Panasonic gives a figure of 7. 0EV of stabilization for the lens when combined with a Dual IS 2-compatible body, and we found it could be very stable. At the longer focal lengths, it's definitely worth setting the stabilization to 'Always' on, rather than 'On half-press' as you'll really need the stabilization to be working while you frame your shot.

The zoom ring is large and positioned so that the balancing point of the lens remains approximately within its limits, even when at 500mm, so you won't find yourself having to shift your hand further forward to full reach. It has a more than 90 degree throw, meaning you get quite subtle control over focal length, but you'll probably need to plan your starting hand position carefully if you want be able to extend all the way through the zoom range in a single pull.
There's a tension adjuster for the zoom ring, letting you determine how readily the zoom ring moves, but on our pre-production unit, the difference was pretty subtle.

We also shot it with the 2. 0x teleconverter and have included a few examples. Before you attach a teleconverter, it's worth pushing the "Zoom Limit" switch into the On position. That way, once you extend the lens beyond its 150mm focal length, it won't then retract back any further than that point: preventing you from smashing the rear element of the lens into the TC.
It's worth noting that, while you can engage the Zoom Limit at any focal length, it doesn't like to disengage when the lens is set to 150mm, so you'll need to zoom in a little, to get the catch to release.
A 2. 0x teleconverter takes the maximum aperture at full zoom down to F14, which can be a bit of a challenge, even in bright light, and in our samples it does rather unpleasant things to the bokeh. We found our S1R II remained at F14 (rather than its 'wide-open' setting), if you take the teleconverter off, so it's worth paying attention to this, if you're swapping it on and off a lot.
Still, even though 1000mm still wasn't enough to get a good shot of the elusive Kingfisher, we did appreciate that this is one of the more affordable ways to get so much reach on such a large sensor.
