I need help also on ND grad filters please.

[MiqsPix]

I need a set of ND soft grad square filters for shooting bright landscapes to tone down the sky. Can you advise me on which strength to get as I assume there will be a set of three, including a holder to fit my Canon DSL 18-55 58mm diameter kit lens. I also have a Tamron 10-24 77mm diameter wide angle lens that I would like the same. Can one filter set fit both lens diameters with an adaptor? Also would the same principle apply to a circular ND110 filter, i.e. can I use one 77mm size filter on both super wide angle lens and 58mm kit lens?

Thanks very much in anticipation.

You don't normally buy a set, you buy the ones you want. Its very difficult to say without knowing how much light you want to block and what the horizon is like. A good starting point is probably an ND3 and ND6 (soft edged maybe?) which you can always stack into an ND9.

Yes and no. You can use "P" sized filters and get a 58mm and a 77mm adaptor ring but the P-sized filters are not wide enough on a 10mm lens. I know because I've tried. On my Nikon at 10mm you can actually see the edge of the filter holder in the frame. The only solutions are to crop it out later on, not shoot wider than about 13mm (on my camera anyway) or buy wider filters (Z sized).

You could get a 77mm screw in filter and some stepping rings so it would fit on a 58mm lens. That would definitely be cheaper than having two ND110's.

I find the ND6 the most useful of my Grads.... ND9 can make the overall exposure a little overdone, making a good sky but leaving the 'unmasked' foreground looking a little overexposed. ND3 works but doesn't really make much of a difference.
I'm starting to recommend Lee Filters or Kood now - I keep hearing about Cokin colour casts.

I second the recommendation of a 0.6 ND grad as your first filter to buy and then add a 0.9 when you can afford to.

As for your ND110 definately get the 77mm and then a step up ring for the 58mm.

Lee filters may be more expensive but they are larger and avoid the vignetting problem on you 10-24mm
