Thank you both!
To me these shots obviously are not merely snapshots, the girls being my twin girls aged 10. But they were taken without any preparation, just playing around with the old D800 and a manual focus lens. I have to admit I'm pleased with the way they turned out.
Although, the second one really is 10cms too close, and the lighting (facing the big tv screen unlike the first one) is less favourable.
But the way the Zeiss renders and the "grain" of the D800 at 3200 ISO are wonderful!
