@Janneke:
No, it's not easy.. but I definitly should have used another lens
If there isn't much light.. and you want to shoot action pictures.. you need some light on that mirror
I'll keep on shooting.. in a couple of months I want to make some nice shots of 'our' little Benji!
Oops, minor correction : BENDJI .
Info : it's the name of a village in Congo about 40 miles West of Kikwit.
And yes, our little boy is only 2 weeks old (which means only 5 more to go !!:D ) and I already have +500 shots !! Most of them will end in the trashcan : I've selected the continuous burst mode so pushing the release button once gives you 10 to 20 pictures of which you can choose the best afterwards. Handy. Don't know if your D450 has it.
