The P5100 has just appeared in the shops here in Hong Kong so I trundled along to my favorite camera store to have a look at it. I bought it as it takes the same adapter as the P5000 and is basically the same camera with an updated sensor.
I just did a quick test in my apartment and the lens behaves very well with my Swarovski 30x and 45x. I use the DCA zoom on these fixed eyepieces and there is basically no vignetting from wide zoom to tele although I have to slide the adapter out a couple of mm at wide and 1 mm at tele. On the 20 - 60x zoom you need to zoom the camera lens to about half way to lose the vignetting at 20x and about the same at 60x. At 30x you lose it at around 2/3 rd zoom.
I'll post some photos tomorrow. Neil.
