Hi all what would be the most useful filters to get to start with ?:thankyou:
 
what are you trying achieve with the filters?

cokin have a reputation now for horrible colour casts
I would look at hitch for ND grads and similar now for ND filters
they still can fit in a cokin cheapy 85mm holder and lens fitting though which is a bonus :)

I think it's more of a reputation for slight colour casts.

Cokin do a set of three of the most useful ND grads. I would start with that - in fact, I did!

Then if you don't already have a screw in polariser, get one which fits the Cokin holder.

Flowers, maybe a close-up filter?
Landscapes - A set of ND grads and a polariser, as mentioned above.

As said, HiTechs seem to have a better reputation than Cokin these days.
you'll need a holder and adapter ring for the grads and and it makes sense to get a CPL to fit the holder, rather than one that screws directly onto your lens.
 
A warm up filter and a blue filter (cooling) are also useful so you can slightly adapt the colur cast depending on what you want to achieve. Might also be worth getting a sunset filter. As mention above ND's and ND grads are a good purchase.

I would actually recommend that you get a screw in filter for your lens. Its slightly easier to use. I would also not worry about getting an adapter ring and filter holder.

I use Cokin P and just have a small amount of blue tac in each filter box. All i do to use them pop 3 or 4 blobs of blue tac on to the rim of the filter (i always have a UV on the front of the lens) and then press the square filter on to it. You can carefully spin the CPL if you have attached that too.

This cuts the chance of vignetting with the filter holder. You can also tac a couple of filters together it you are looking to combine affects.

I find this quicker than having to attach a square filter holder, and its also less obstructive to have on the lens. Obviously you have to be careful as you are only using blue tac and the filters are not really secure but it works for me.

Nope - I bought that set and they have a horrible magenta cast - useless.
i.e. a simple afternoon shot of the sky

I've seen this picture twice on the forums and my results we not nearly as bad, even with 2x 3-stop ones on and long exposures. (compared to that short exposure)

I don't think that gives a fair impression of the cokin filters, but they do give a magenta cast when used for long exposures
 
I recently bought my Mrs a Cokin P 85mm holder (£5 off ebay) and some Hi-tech ND grad filters (£30 from www.formatt.co.uk). The holder takes the Hi-tech filters fine and - despite the "allow 28 days for delivery" warning on the website - they took about 2 days to arrive. I can't discern any colour cast either, though you can also buy these from formatt if you so wish.
 
I have a filter, NOT cokin but worth pointing out the cheapness of filters.

photo with hitech grads on..soft edge..I should have bought the hard edge ones really for my purposes.

one cheap ND filter later

frankly I like the picture but the cheap filter added an unintentional colour cast, which could be removed later but i'll see about that
for the sunset it luckily looks okay

That's raw converted to jpeg with no processing. Hows that not a fair representation?

ISO100, f4.5, 1/160th sec on a canon 50D with a 24-105L IS lens at 24mm, white balance set to AWB.

What am I doing wrong then?

Edit: forgot to add with the Cokin P ND 8x

I don't know if you are doing anything wrong, and I apologize if it looks like i was trying to discredit your experiences, perhaps my filters are slightly better for whatever reason.

Jim.R, you have the same camera as me..... can you recommend some?

Also, what is a CPL?

Cheers,

The Cokin filters definitely do produce a colour cast, I'm currently ordering the Hi-Tech ones as a replacement.

Regarding a circular polariser I'd say it's the No1 most useful filter for landscapes, the grads I use occasionally whilst the polariser sits on my lens most of the time - for this reason I much prefer a screw-in polariser that fits directly to the lens, I just find the Cokin holder is too cumbersome for "all day" use.

A screw in one would probably be the most convenient so a 58mm one would be the job. As for recommending one i dont know as there are lots of options, my was cheap but you can spend big money on CPL's
 
I have Cokin grads I use on film, never seen any kind of colour cast.
That doesn't mean it doesn't exist in digital land, but I find it hilarious that peeps are prepared to spend hours completely rewriting an entire photo, and they do...frequently, yet Cokin still get hammered for what is a fairly minor issue.

I use a Hoya Pro 1 D...good quality and not too expensive, it's also thinner than standard filters so on my lens doesn't produce any vignetting
