There's been a fair bit of hemming and hawing about the Panasonic 100-400mm, particularly after some really lacklustre samples out of DPReview. Well, it looks like there is no reason for concern. As usual, Mirrorlessons has come through with some very nice shots and a thoughtful hands-on. Check out the first bird photo with the accompanying 100% crop, as well as the 3 shots of the squirrel. All at 400mm, f6.3, and shutter speeds between 1/100s and 1/200s. It doesn't perform as well on the Canada Geese, but the ISOs were much higher, and the shots look like they were taken from farther away, so there's more atmosphere in the way. I feel like it's hard to expect any lens to deliver great results when shooting at such a large distance. I expect the 300mm/f4 is still the more impressive performer, but these results are a clear step up from anything I've been able to achieve with the P100-300. I wonder what will happen if someone puts the lens on a tripod, for once!
