What did InSanaty Clause bring u 4 Xmas?
you shouldn't need the concentrate later, but the additional sugar at the start will simply mean more alcohol rather than sweetness IMO. Bret well I'm degassing my wine, pulled a cup and filtered it with a coffee filter. It is harsh, but drinkable and whoooo-boy!!! it got a kick..... I won't bot...

"We never rule anything out..."
Interestingly, Pentax seem to get better quality out of Sony's sensor than Sony can. Clearly the sensor itself is not the only factor. I've noticed that too. I know someone who has a Sony Alpha with (we think - they're both 10mp) the same sensor as my K-m, and there's a definite difference. It mi...

Circular or Linear Polarising Filter for Digital?
Hi all, I am a bit confused on the polarising filter issue. As most know there are two polarising filters one is linear and one is circular. Could someone please explain what the difference is (other then in price) as it seems that the linear one is recommended for 35mm and the circular one is r...

Circular or Linear Polarising Filter for Digital?
Nothing to do with digital or 35mm as far as I recall. More to do with AF or manual focus cameras. Potential for incorrect exposure and focus.

Circular or Linear Polarising Filter for Digital?
Nothing to do with digital or 35mm as far as I recall. More to do with AF or manual focus cameras. Potential for incorrect exposure and focus. Interesting, never noticed any problem in this at all. Maybe its more an issue with 'cheap' pol filters? Thanks for that.

Circular or Linear Polarising Filter for Digital?
Linear and circular pols work in a different way, nothing to do with cheap vs good quality filters. However a lot of people including myself have not really noticed any problem with linear filters on digital. Even if these was an issue, EV compensation and manual focus are at our disposal.

Circular or Linear Polarising Filter for Digital?
However a lot of people including myself have not really noticed any problem with linear filters on digital. Even if these was an issue, EV compensation and manual focus are at our disposal. I still use linear ones. I've never had any problem with AF using LPs, and I used to believe that there was ...

Circular or Linear Polarising Filter for Digital?
I suppose if you already have a linear polariser, you may as well stick to it. But for purchase, I would go with the recommendations and buy a circular one.

Circular or Linear Polarising Filter for Digital?
There is a good article in this weeks amateur photographer (22 Jan) on polarisation. It states that circular polarisation is preferable on DSLRs, mainly because of exposure and foccussing. I beleive this is not an issue with Pentax kit, but may be with other brands. Davex.

Circular or Linear Polarising Filter for Digital?
Having just read the above link it seems that I may have to get an circular, just to be on the save side, even I have not noticed any of the given problems so far but it may just come when in need of the picture and then it is too late. Many thanks for your input, and the link was very informative.

Circular or Linear Polarising Filter for Digital?
I use LPLs with very few problems. One thing I have noticed is that LPLs seem to give a stronger effect than CPLs on the same lens. Does anyone else find this?

Pentax produced CPLs particularly for the LX to overcome a metering problem with linear ones.

Must Have Photography Accessories?
I have a rocket blower, and, more recently, some 3M Lens cleaning cloths! Filter wrench - no Bean Bag - yes, but a rolled up scarf, jacket or almost anything soft that will protect the camera if it is resting on a rough surface. The new pentax lens caps are fine - in the main, but limiteds are so...

Sadly I got a lot of those items in my bag (and more). I use a Lowepro Slingshot 300AW and in the TOP compartement I got a set of ND Filters (49 and 52mm, ND2, ND4 and ND8 one of each plus Polarising Filter in 49 and 52mm, all in a filter pouch), A Yellow HigViz Vest with "PHOTOGRAPHER" printed on i...

No longer embarrassed to be the owner of not one but two triple-axis, hot-shoe spirit level bubbles:P Jon:wink: I've got one double axis one & now a disc type one (which stays on the carera as a hot shoe cover). I don't use either for everyday shots, but for IR work, where I can't see ANYTHING...

Must Have Photography Accessories?
For me: lens pen, mini tripod, cordless remote. Being able to set the camera up for duration exposures anywhere and everywhere is a godsend. Further down the list would be CPL, macro filter. And of course spare batteries and memory cards. For more money I vote for an Arctic Butterfly: best most fool...

Shooting through angled glass.
I am wondering if we have any experts here on the optical qualities of glass? More specifically, the effect of shooting through laminated glass at different angles, and how to mitigate these effects? As some of you are aware, I shoot a lot of photographs from aircraft, and although I am getting ther...
