K100D and InfraRed
covers IR with a K100D. You may have to up the ISO, but that shouldn't be a problem as IR film was/is grainy anyway. An R72 filter is a good investment (IMHO)

An R72 filter is a good investment (IMHO) This answers a question I had a few days ago. I have some letters to my grandfather when he was in a Japanese POW camp in China 60 years ag...

K100D and InfraRed
Hmmm, I wonder how you get the IR filter off the sensor... I've got a chisel and a mallet. :shock: :D Anyone had this done? Know how much it costs? Dan

K100D or K10D + Prime
I have owned both a *isD (one of the first ones out), and within the past year acquired a K10, along with the additional battery grip D-BG2, and that was a life saver on a recent 30 day coach tour through the maritimes, because I always had another spare battery to rely on and in fact had to make us...

Question about macro lenses
At closer distances the macro lens might show higher resolution and sharpness and certainly a flatter field. For portraits this could actually be undesireable as it might not be flattering enough! Both will give you the ability to tackle portraiture and depending on the lens you might add a soft ...

Why is there a cut out section on top of Pentax lense hoods?
Firstly, you are putting the hood on upside down :wink: The removable section goes at the bottom and is there to allow you to rotate a polarising filter without removing the hood. It is a good idea to use a hood at all times since it prevents stray unwanted light causing flare and lowered contrast ...

Am I compromising my photography with lense filters?
I have Hoya UV filters on most of my lenses ( I have purchased the more expensive Pro variety) as I am always worried about scratches, my kids etc. Do most of you do this as well or am or being over cautious? The title of your thread, and the question in your post are actually two completely separa...

Am I compromising my photography with lense filters?
Thank you I will take a look at the thread outlined and maybe do some experimenting. Much appreciated. Having looked at the thread, I feel a little hoodwinked by the shop I bought my lens from! I always used to use a Skylight 1b on film and continued with the same practice for my digital len...

K10d Alternate Lenses
The lens hood on the Tamron doesn't have a slot for putting your finger in for rotating a circular polarising filter, which is a pain. Otherwise, I like it!

Shots from a 2 seater hairyplane
You'll need a U.V. filter to cut the atmospheric haze a little bit. Also, try to include some part of the airplane (ex. wing tip or wing leading edge or wingstrut...) so you will have something to use for orientation purpose. Try to go with a Cessna or any other high wing plane, so you won't have ...

Multiple exposure mode
Thanks for this info guys. This is amazing info and I thought I'd read my K10d manual cover to cover! I wish I hadn't bought that ND8 filter a couple of weeks back now!

extension tubes
there are 4 ways of getting into macro photography (some of them can be combined for Uber-Macro) 1: Reverse a short prime. This is most commonly done with a ~50mm lens. It is the cheapest way of doing Macro if you already own a short prime lens. You get an adaptor ring which has a K mount on one ...

extension tubes
Mongoose's summary is very good, but incomplete. There is another method of producing macro images, and that is to stack two lenses together. If say you mount a 200mm lens (can be a zoom) on the camera, and reverse mount a 50mm lens in front of it, you get a combination which produces around a 4:...

Paper filters for photography. Say what?
Andrew, I don't understand how you get some of these effects without using at least two images. for example, if you used paper filter covering the whole lens on the dragon image, how come the dragon is in front of some the 'starburst' shapes. they look like multiple exposures to me. Ca...

Paper filters for photography. Say what?
it's the out of focus specular highlights that take the shape of the filter. any light sources in front or behind the point of focus. Andrew chose his subject matter very well for this technique. without those bright light sources in the background, the effect would just be blury, hazy, foregrounds...

Paper filters for photography. Say what?
Well, Mr Justgetout, I think you need to try this yourself and see! It's really fun and it works exactly as I described. (And yes, the wider the aperture you can use, the better. I used my 50mm 1.4 for this) But because you asked nicely, I re-shot the scene without the filter on. I also broke it...

K20D and Infra Red
Some flashes do, unless the manufacturer filters it out. The Pentax Nocta, from the Spotmatic era, was such a flash. It was covered with an opaque IR filter so no light could be seen. The special 300mm lens and electronic viewfinder meant that covert photography could be undertaken. The screen pr...

K10d image problem HELP!?
Right, so I'm suing my new Pentax K10D and a B+W ND1000. Occasionally I get these massive streaks down my images. I haven't got a clue why. They don't seem to appear without the filter. Is it the fault of the camera or the filter? It's happened twice now, but it doesn't happen all the time. Here'...

K10d image problem HELP!?
Is the filter uncoated? On the first one it looks like some kind of purple flare caused by reflections. The second I'm not too sure about though. It looks to good to be flare, can you see any defects on the filter?

K10d image problem HELP!?
To be honest I don't know if it's coated or not. It's a "B+W 52mm 110 ND 3,0 - 10 BL 1000x" Problem is, I was shooting today with a mate who has the same filter with a larger thread but he had no such problem. No visible defects on the filter.
