I posted here before going on our trip to Morocco and was given some great advice ... that I took and used
Now I have a Sigma 10-20 mm wide angle lens that is super, I bought a set of Tiffen and a Cokin P set of neutral density filters.... all ring fittings are 77m my question is
is there a way of using these 77mm filters with my other lens `s, I believe there may be a `reducing ring` that I could use, I`m sure its not called that but someone with the knowledge will put me right
or should I be buying sets for each individual lens?
I have a set of square filters that fit into a holder with a set of reducing rings for various sizes. Bought them years ago for my Olympus OM2n but luckily they still fit my new digital kit. Cant remember where I bought them as it was so long ago but surely reducing rings are still available somewhere.
If you are using digital do you really need filters...particularly if you are shooting in RAW?
remember a raw image is simply a digital negative. Certainly digital has taken away the need for may filters but a graduated ND filter for example is stil worth its weight in gold.
Thank you for your response`s, I am having a great time with the filters incl the polarizer.
Question
I know that I require STEPPING RINGS to be able to use my filters on my other len`s
Do I require STEP -UP or STEP DOWN
All the filters bought are for the wide angle Sigma with a 77mm ring.
I can get what I require with 2 rings from Speed Graphic, catalogue on doormat when I came home this afternoon.
the other 2 lens rings are
67mmm
55mm
I've used Grad ND filters particularly for landscape work and found them to be good but I have to say I'm beginning to think I don't need them anymore. LR2 has a pretty nifty Grad Filter that not only allows you to vary the exposure across the gradient but also, brightness, contrast, saturation, clarity, sharpness and a colour grad.
The one problem I've had with Grad Filters - apart from the fact that the Cokin ones act as dust magnets - is that they are linear. Quite often I've found that some part of the scene needs to have a different exposure but the Grad Filter effects more than just that part.
Again singing the praises of Lightroom - it has a an Adjustement Brush that lets you paint the adjustments just on selected areas.
