Filter Drawer/Window?
One of the specs for the new DA* 300mm F4 is a filter drawer or window (depending on which site you look at) does anyone know what this is? The size of the filter is 77mm, would this be a threaded filter?

Filter Drawer/Window?
It probably refers to placing gelatin filters somewhere at the rear of the lens, in addition to the normal front-rim screw in filters.

Filters for the Bigma
I have just purchased a Sigma Bigma and i am wondering if i should purchase a filter or 2 for it. At 86mm they don't come cheap, but i was thinking i should put a UV on it and maybe a polariser. Gwyn i know you have Bigma, do you use filters on it :?: and if so are they benificial, even if only f...

Filters for the Bigma
Hi Clarky, As Gwyn said; Forget a polariser. Zoomed in you would need all the light you get. Why lose another two stops of shutterspeed. The lens ain't that fast :wink: I think i would like some kind of protection filter for it, when i have to use it in bad weather or on the coast.( salt water spr...

Rambling mode on: I guess you could have a point :) Maybe it is a needless worry, because you should expect the newest technology in lens coatings would prevent actual damage from the ''Elements out there''. On the other end i still prefer a good cleaning of a relative cheap filter over a good cl...

Filters for the Bigma
...this Bigma has such a big front element i am worried something is going to hit it eventually. But in saying that the hood gives it pretty good protection so maybe i am being a bit paranoid. Just keep the hood on. If you think about it, if there was a filter on there, anything that might damage t...

Filters for the Bigma
I would use a UV on any lens if I was near salt water 'cos salt has a nasty habit of attacking lots of things and the coating could certainly be at risk. On such a nice lens as that why risk it. On such a long focal length it is very unlikely to affect picture quality. I personally don't think it af...

I can quite believe that salt would make a mess of any lens coating - be it a salty splash or just salty air. Anyhow, being near water often means a lot of UV haze - another good reason why I use a filter.

Mystery Lens??
Can anyone identify this lens ?? Its listed on E-Bay as a Hoya HMC 52mm, obviously thats the filter, just not sure what lens it is or even if its a Pentax. I suspect it may be a 50mm macro??

RE: Out of the two.....
I have the Tamron and like it very much, myself and others have posted a few pics here before. A lot of people wrongly give them a bad press; they need to be used with care: solid robust tripod and head (probably weighted down), mirror lock-up, and almost certainly a UV filter (30.5mm ones fit behin...

You're right: the lens is no lightweight - but nor am I or my K10D :? Too many Danish pastries, I expect. Actually, it's a very good deal. The filter would perhaps have cost a tenner, ditto the tripod, and you can probably sell the fifties for 40 smackers. Net cost of excellent F lens: 40 sq...

Sigma 17-70 - HDR like images ?
Do you use an ND grad filter perhaps? I would say most of the people who ask you probably dont know much about photography, or arent very experienced, and wouldnt know that its possible to have a properly exposed land and sky without HDR :lol:
