Good catch!

I would go with Keratella as well:

Zeiss Standard WL (somewhat fashion challenged) & Wild M8
Olympus E-P2 (Micro Four Thirds Camera)

Excellent video images ... thanks
Out of interest: What’s the frame-rate ?
[apologies if I missed it]

Thanks all😊 My framerate is 15😩 I can not find a way to change framerate on Toupwiev. Maybe it is maximum on my USB camera🤔 //KD

Thanks KD ... 15 may well be the maximum if it’s USB2
... my 5.1 MP ToupCam struggles to manage 4 [which is obviously hopeless for video]
