ND filter advice for DA Ltds
I'm on holiday in Hong Kong at the moment and saw a Hoya eyeglasses display in an Opticians yesterday. That was a first for me, I don't recall seeing any Hoya products when I was growing up here. Pentax have (or rather had) a medical division, which IIRC included eyeglasses. Perhaps these have now b...

Pentax spectacle lenses in the UK are now licensed to Specsavers if I remember correctly. They aren't made by Pentax they just use the name. There was a tie up between Pentax and Zeiss until recently. Hoya's main spectacle brand is now Seiko. This is the history: http://www.seiko-optical.co...

ASDA use Hoya spectacle lenses for all but a few specialist prescriptions. Hoya made lenses (glass) for various manufacturers in the '70s and produced their own range of camera lenses in the early '80s. The glass in them was Hoya's own HMC (Hoya MultiCoated) which was new for budget-priced lense...

I bought a Cokin filter system including a 49mm adapter. I've found that I don't need to stack filters - CPL + ND is almost always overkill - so use only the 0.9 grad ND, which I hand hold in front of the lens. If I need a CPL I use s 49mm screw-on filter. I may still buy a screw-on grad ND ...

Interesting thread. I was struck by a thought. How many people who shoot RAW and use Lightroom (with it's post processing graduated filters) still feel the need for grad filters on the lens? I would think if I shot jpeg, I would still use my ND grads. As it is, I haven't used them for ages and fe...

If you need to get a long exposure to create certain effects with waves and water, then you need a physical filter. No amount of post is going to recover info out of blown highlights from an exposure measured in whole seconds. There is one way and that's to stack multiple exposures. btw the perf...

i have a set of cokin-a holders that is getting left home more and more. even though my k7 doesn't really have much of a reputation for having much dynamic range, the 10 and a bit stops it does have covers most situations. in post-processing, i generally try a software to darken the sky. first...

There are essentially two issues here. Firstly, would you prefer to faff around in the field or faff around in front of your computer? Secondly, do you also shoot film? Digital has provided several ways of getting to the same end. Which route you choose is pretty much up to you. K.

To be honest I think I'd rather use NDs than fiddle around stacking exposures on the laptop. I know how to use an ND filter and you only need to take one shot! :lol: Did Pentax ever offer ND filters?

It wasn't Cokin! I used http://www.formatt.co.uk/default.aspx for the filters (it's the Hitech system). The 49mm bayonet adapter screws into the lens and the filter holder clips onto the adapter. The Hitech system has the slot for the polariser at the front, which has turned out to be a problem...

IF you're going to get grads then get the square format ones, they give you the ability to place the horizon anywhere in your photo with screw-ins the horizon is always in the middle. I have the Cokin Z-pro GND kit, which contains the holder and 3 grads, you only need to buy a screw-in filter rin...

Thanks Stefan Do you know if this system fits the DA21 without vignetting? And is there a way to fit it onto the DA15mm (with its built in petal hood)? Cheers

Yes because you can reverse mount the holder so it will only hold a single filter. This should link you directly to the page of the z-pro. Recommended for focal lengths from 20mm onwards (35mm format) so... with the 1.5 conversion it means it should be okay with ~13mm I don't think you can...

The only Cokin "A" filters I have are some sort of half closeup thing and a sepia filter (impulse buys when I was about 15 and not terribly clued-up about photography!) If only I'd been hunting for a full set of SMC K lenses rather than fiddling about with filters... :lol:
