I am new to this forum having just purchased a D5300 (previous Olympus E500 and E3 user). I already had the Metz unit and am trying to work out whether its worth using it with the Nikon. I've got it working but am not sure that it's actually doing all the ttl stuff (it might be that it's just not suited to the Nikon system of course and I haven't realised it yet!) I've seen some good results from people using the inbuilt flah and a just a simple foam diffuser for macro. So do I persist with the MS-1 or just go down the simplw route - I am just a hobbyist photographer. Thanks all.
