Hi ,
I have just bought a brand new OMD EM-1 with 12-50mm kit lens, but apart from that ( and a tripod) I have no other camera equipment . I want to start to build up a bit of a tool kit of essentials and accessories. One thing I[d like to get are some filters. Most of my photography is landscape , bushwalking, beach etc...

I have read I can but either a series of individual ND filters (which can be "stacked") or a Variable ND filter . The variable filters are more expensive but obviously cover the whole range , and as cheap as buying 3 or 4 individual filters.

So questions are :

1. Which way to go - variable or a few singles? If singles what would be a good range to get ?

2. What are good quality brands that won't break the bank? eg. Hoya OK?

3. Any other filters you think the new photographer should not be without ?

Thanks in advance for your advice.
