smc FA 50mm f/1.4
some of those filters cost as much as a lens. maybe you'll need a cheaper filter to go in front of your hoya to protect the hoya. javascript:emoticon(':twisted:')

smc FA 50mm f/1.4
With all that computing power going into the design, if it needed an extra bit of glass it would be designed with one...Adding more glass to the optical path can only degrade the image, it can't improve it. Of course, but it wouldn't matter to me if the degredation was very slight indeed, if my lens...

smc FA 50mm f/1.4
Talking about filters, I'd like to apply for the "Tuesday muppet award". I've put a UV filter and a thicker lens cap on the Pentax 400mm I acquired recently, and I was just thinking, hmm I wonder if it still fits in the case. So I slipped it into the case, and lo and behold, the top ...

smc FA 50mm f/1.4
Fifth: close to fourth, damage done to the front element caused by a filter smashing when the lens is dropped or knocked. It must be remembered that filters are much more delicate than lens elements, and much more likely to smash. When they do, it's likely that shards of glass will be driven inwards...

smc FA 50mm f/1.4
I always use UV filters as a final level of protection. I also use a hood but that's only when the lens is on the camera. However, people forget that it's not only when it's in use that a lens is vulnerable. I had a lens fall out of it's case (which I hadn't done up properly) a while ago. The len...

300m Lens needed or over
I look forward to receiving mine later today. It arrived and I'm very happy with it. The zoom is significantly stiffer than my old lense, but that's not a problem. Mind you, having to buy a new polarising filter for it is! I suppose I could've selotaped the 58mm filter from my old lense onto it, ...

Mind you, having to buy a new polarising filter for it is! I suppose I could've selotaped the 58mm filter from my old lense onto it, but I suspect that might not be satisfactory. ;-) If you buy a new polarising filter how about buying one larger than you currently need, and a set of stepping rings...

300m Lens needed or over
how about buying one larger than you currently need, and a set of stepping rings That's probably a very sensible solution... though as I'm waiting for Sigma to get round to making/importing some more PK-fit Bigmas, which take an 86mm filter, that'd be quite a step up! Anyway, too late now. Ebay i...

Problem with Infrared filter (on Nikon...)
Hello! Recently i got an IR filter and tried it out on my K100D. As far as i'm concerned - everythings ok. BUT! I tried it on my sisters Nikon D40X, and nothing. It just makes completely black pictures. We tried different modes, nothing. What could be the problem? Could this be, that D40x d...

Problem with Infrared filter (on Nikon...)
Using an IR filter with a digital SLR relies on the CCD's bayer matrix and filter to allow at least some IR through! Some cameras (I've heard some Canons have the issue as well) have a heavy IR filter (or the sensor isn't sensitive to IR) so although the IR gets inside the camera it isn't recorde...

Which is Best?
Can anyone advise me please...I want to photograph insects/dragonflies etc by the water ie. wildlife photography and want to filter out the reflection of the sun/water etc...which poloriser would be best suited for this...Linear or Circular or maybe something completely different...want to buy one b...

Which is Best?
A circular polarizer will be fine for this. Linear polarizers can cause problems with auto focus cameras, I believe. Also with a circular polarizer, you can rotate the filter to get the best effect.

Which is Best?
Also with a circular polarizer, you can rotate the filter to get the best effect. You can and do with any polariser, circular or linear. The circular or linear refers to the direction of polarisation utilised.

Which is Best?
Think of polarising filters as Venetian blinds, the filter light waves coming in a particular direction, so if the blades on your blind are horizontal then only light coming in that direction gets through, rotate the blind and light coming at a different direction gets through. Both linear and ci...

OK, a circular polariser is easier to rotate? :oops: A fuller explanation of the options can be found here

Waterfall problem
The essential thing is to use a slow shutter speed, and that means using a tripod to keep the camera steady. For water shots, you may need to put a neutral density filter on the lens because the slow shutter speed will lead to over-exposure unless it is a very gloomy day. The great thing about...
