Whoever wants to experiment with RAW unbdingt speicheren, only focus, AF out, anyway stabilizer on the tripod, and thereby enable Graufilteraufschrauben not the push / adjust the focus, mirror lock, continuous exposure to and use Kabellauslöser. Well, then expect just how much longer you have to expose well ... but, there are also quite great videos on the net.
For me, the thread fits the way easily.
The question whether it is necessary to spend more money / should I leave times the professionals - for me, my equipment and (small) experience no longer needs it at least for now. Incidentally, I was also previously stayed at the local "shop" and abe at other dealers looked (unfortunately it lacked both the advice and the filters), there could have been my only order a neutral density filter as desired, however, there was no consultation why I now should buy this or that. Half a day for the real dealer, I did not apply, so again bought something by mail order and no regrets after all.
