ND filters need help..

I have been wanting to try some long exposure shots for a while, but I don't know the best route to go.

I don't' have a Ef-s 10-22mm yet but I want one in the future.

So with that in mind would I be best buying a filter for it as it has the largest filter size of them all at 77mm.

And then buy adaptors so i can fit them to my other lenses which have a smaller filter size?

Is there any problems with that train of thought.

I have a cokin square filter attachment, would that be suitable or is it better to use screw on filters.

Your thoughts and experience would be gratefully received.

Thanks
 
Think you need to do a bit of cost estimating here.
77mm filters are quite large and expensive and whilst your idea is correct in principle it may be worth checking out the cost of individual filters or 77mm filters only plus stepping rings (or a permutation of these).
Don't know what other lenses you have, but beware of any vignetting with a stepping ring.

Cannot answer your Cokin question, but again watch for vignetting down around 10mm end of that lens you mention.
 
Go for lee Slide in 100x100 filters By far the best and if you have a lot of lens sizes possibly the cheepest way to
 
I am definitely only an amateur, so you may wish to take this with some salt.
I went through the same dilema a little while ago. I went the stepping ring route (I did already have polarizers for each filter size I own, and UVs, and thought that things a getting a tad silly). My experiences are,
I have found that on Ebay, stepping rings are relatively cheap (in comparison to filters!)
I personally have a 72mm lens, (and a couple of 58s and a 52), and I knew I wanted to get or at least hire the EF-S 10-22 (which I have at the moment, so I can see whether I would want one permanently, or hire a couple of times a year....).
So I decided that I would buy some stepping rings, 52->58, 58->72 and 72->77 (whilst I was about it), and then bought the ND/grad and colour grads that I wanted in 77. There was about a £10 difference in cost.
Obviously though I am stuffed if I now get a wider filter lens.

Bear in mind though, that the 10-22 only supports 1 filter at 10mm. (it says this in the manual, I couldn't see why, so I tried it, doh, must have been asleep).
On the photos that I took to check the lens and the way it worked, the corners are missing when I had the UV filter, and polarizer and grad. However, it is still a brilliant lens. This is with 3 filters on, that the corners are missing, but as I am considering trying to get some more panoramic like shots, I am probably only missing around 10% at most of the area I would want. If it were my own lens, I might do-away with the UV filter, and have the polarizer on permanently (hmm, that might make things darker, but for landscapes... longer shutter times are possibly not too much of a problem), but this is a hired lens, which I could not distinguish from new.

My understanding is, that the slot-in square filters, are less likely to have this issue, as they are much wider than the lens (did I see 110mm somewhere?), however, I believe there are two types of holders too, a single, and a triple, in which case the triple might still have an issue. But this paragraph is just what I have seen around, it could be complete rubbish.

I can't really comment on the full service, as I haven't sent the lens back yet (but I don't expect that to be the cause of any problems), but lensesforhire.co.uk is where I hired this lens from, and so far the experience has been good. Arranging for the hire of the lens was simple, I selected Royal Mail delivery, and it arrived by 1pm the day before the hire 'starts'. I even got an email the day before that to say that the lens was sent, and the tracking number (it is also a good reminder to expect the lens, as I had placed the order some time ago!)

With the square filters, I believe that you can rotate the holder, but this means that all the filters are rotated by the same amount. Thus, if you have a polarizer, with a grad (or two grads), I think that you might be restricted in which angles you can employ. Again, this is what I think is the case, it could be rubbish.

On any of the other lenses (52, 58, 72), which are 17mm at the widest, the stepping rings cannot be seen.

Edit:
Just seen this thread, post 18 might be relevant if you go the Cokin route,

Thanks for your replies, I have checked the other lenses,

  • 50mm 1.4 is 58mm
  • 17-85mm is 67mm (have a polariser for this)
  • 70-300mm DO is 58mm

My Cokin holder is a triple slot 'P' series if that makes any difference.

I never used uv filters on these lenses so I was thinking that I would only need the ND filters.

With that in mind would I have any of the issues with vigenetting on the above lenses with the 77mm adapted down to suit the 58 & 67mm filter size, if I decided to go the route of screw on type and not the cokin as I find it a bit fiddly.
 
I do not believe that you would have any problems if you got a 58->67, 67->77, but I cannot answer with certainty.
With my 17mm length, 58->72->77 I have had no problems. (apart from the fact that the 77mm filter on the end of a kit lens looks a little odd :) )

If you do go the screw route, a couple of filter wrenches were the next things I bought from ebay:
http://shop.ebay.co.uk/items/?_nkw=...3286.m270.l1313&_odkw=filter+wrench&_osacat=0

Seems that when I put the filter on inside, then walk outside, the temperature seems to make my filters set (and as they are the type with internal spin, they are a job to get hold of).

Thanks for your very informative post's certainly gives me food for thought.

Smart little wrenches them, never would have known about them unless you said.

Probably would and up using a pair of water pump pliers knowing what I'm like. :bonk:
 
You may not find them necassary, a lot of people suggest using a rubber glove and pushing the lens into the palm of the hand.
However, if you have a circular filter, which has a rotating front (like a polarizer, or a graduated filter), then that method doesn't work.
