Be sure you are buying a linear polarizing filter because you don't need to rotate a circular one. Absolutely not correct. (But maybe you were joking... but just in case someone gets the wrong idea...) Both circular and linear need rotating. The linear polariser will stop the autofocus from worki...

... Both circular and linear need rotating. The linear polariser will stop the autofocus from working. You need a circular polariser. Matt Can I buy a square one and stick it in my cokin square filter holder thingy and twiddle that a bit? ;) ;)

Can I buy a square one and stick it in my cokin square filter holder thingy and twiddle that a bit? Of course - just rotate the whole holder :P But... it doesn't work if you want a polariser AND an ND-grad. Then you need either a round polariser, or stack two holders together (Lee filters can do th...

... or stack two holders together (Lee filters can do this, not sure about Cokin). Matt I can stack a few filters together with the cokin system, but not separately, so if I rotated the polariser, the ND filter would be in the wrong place. But I could try using the camera upsidedown.

AJ, The Lee one is this: http://www.leefilters.com/CPTS3.asp?PageID=134 You then have two filter holders with the front one connected to the rear - the front can then rotate independently. Upside down sounds good though... :P Matt

AJ, That's reasonable. Cokin and Kood do a round circular polariser for the Cokin P holder. It fits between the lens and the first filter (you'll notice the P-holder has the first notch slightly wider). With the 12-24mm you can just about get away with using the P-holder with a tiny amount of vi...

K10D wide angle lenses
Just to add another little twist... The 12-24 is a very, very fine lens. But, dare I say it, the 16-45 is probably more usable. Compared to the 18-55 it is certainly better, if only fractionally wide. However, it has a certain "quality" that I can't get from the 12-24 - it may be bec...

Filters - Cokin A or P?
Thinking about investing in some grad ND and circular polarisers. At the moment have the two K10D kit lenses (18-55 and 50-200), which both happen to be 52mm filter thread, and my brand new 100mm macro, which is an old-fashioned 49mm. I guess at the moment the smaller Cokin size would do fine, but a...

Filters - Cokin A or P?
Anything that is interestingly wide, or impressively long, or mouth-wateringly fast, will require P series filters... G Or bigger such as the Cokin X or Z Pro or Lee System - but then you're talking LOTS of money but less chance of making filter purchasing mistakes you'll regret... Been there als...

Filters - Cokin A or P?
I've used Kood and Hitech - both pretty good P-sized filters. At the moment I use the Lee foundation with Cokin Z-Pro ND grad filters. (Speedgraphic have a killer deal on a set of ND grads ;) ) You can just about get the Cokin P to work on the SMC-DA 12-24 with a small amount of vignette at 12...

Filters - Cokin A or P?
Paul, With the standard Cokin P holder you will have problems at 14mm. There is a wide angle adaptor now that will hold a single filter which may well be ok. Having got the 12-24, I found it better to go for the Z-Pro grads with a Lee WA ring (at great cost :( ). They have been significantly bet...

Buying Advice!
Thanks. Now, if I am shooting indoors and there are lights around that can't be avoided (sometimes some of the shots wil require me to shoot a kitchen photo with low hanging lights that are on and can't be turned off). How do I reduce the glare in the final pic (the halos around the lights and brig...

There is no reason for not using a flash. I am a newbie so I thought it would make the pics worse. Another thing, I can use a UV filter to protect my lens right?

Buying Advice!
Search these forums for various opinions about using, or not using, filters. A UV, or haze, filter is said to work best (as an optical filter) in sunlight. I'm thinking you're not going to get too much of that inside a building. If it is physical protection that's a different matter and before yo...

help please
I can't seem to get good sharp images, they always seem 'soft'. I've been putting it down to my poor technique, bad light, camera shake, etc. Compared to the images I've obtained with my fuji s5000, I'm not impressed. Can you peeps take a look at some images and let me know if it's me, the ca...

infra red conversion of istD
The *ist-D will take IR images already - AFAIK it's quite sensitive in the IR region. You just need an appropriate filter. Think the K10D is a bit more aggressive on its IR filter. Matt
