infrared filter
Just to quickly try the K20D with infrared; today in sunlight I found that, ISO 800 and 2secs @ f8 achieved a reasonable image. These are a lot longer exposures than on the Pentax istDL2. Will try that as soon as I get a good day. regards

infrared filter
My attempts at this involved 20 or 30 second exposures with apertures in the f5.6-9.5 range (and 100 ISO). As the guys on here pointed out, it's an uphill struggle given the effectiveness of the sensors' IR filtration. It's worth a try though and I'll have another go if the sun ever comes out agai...

infrared filter
This one was done with the K10D and a cokin infrared filter so it is possible. Full version with metadata Shutter Speed: 1 second F Number: F/5.6 Focal Length: 18 mm ISO Speed: 400 This is not the standard black and white infrared but it really is a infrared photo and made it into a duo...

Thank you Susan, it's my only infrared photo that I like. It's really hard to do a proper infrared with the K10D. Here is the original photo BTW

I prefer the editied one, I wondered what the round bit at the bottom was in the editied one, now I can see,perhaps if you cloned it out it would look even better. Just a though. You did right in cropping it though.

Prefer the edited one too but now you have an idea what you get when using an infrared filter and what you need to do. About cloning out the lens flare, I've thought about that but most don't find it distracting and you will always see that you cloned it out. Some things are better left alone. :w...

infrared filter
Apologies to those who saw this feeble effort in the Your Photos section some weeks ago, but it's probably slightly relevant... ...was actually the best I've managed with the K10D and IR filter. The K20D may be even better/worse in IR terms. :wink:

Thanks Conky, Still not been able to take any photo's with IR filter as the weather was stormy yesterday and today still raining. regards

K20 sensor clean on start up
When I had my K20D it was set to operate on start up, no problems at all. Have you got the same facility on the K7, and do you use it?:? Yes and yes although it is different in that rather than the whole sensor assembly being shaken it is just the low pass filter in front of sensor that is vibrated ...

If you want a 70-300 zoom I just bought a Tamron 70-300, and picked it up for £96 including next day postage and a Tamron filter (which had a £15 price sticker on it). see and good luck! I'm really pleased with mine, and the thread shows others have achieved some great shots!

Sailing photos
You've pretty much got it sorted. This is one instance where I might use a protective filter on the lens to avoid salt damage.

K20D metering
Hi all, Just an interesting thing that came to me in a bit of inspiration... having read about the Leica M9 and the issues that beset the M8. Had to test it first, but the K20D meter is sensitive to IR :shock: Try this: * Darkish room * Spot metering, Av mode * Take a remote control and po...

K20D metering
Just to add a little more info to my previous post (in case it was confusing!)... The Leica M8 has big issues with Infra-Red (IR) bleeding which seriously affected the image quality. M8 users had to put an IR-cut filter on the front of the lens to resolve the issue. Thankfully for those rich enou...

K20D metering
Very interesting Matt! Not able to add anything about the K7 - still have the humble K10D. But sometime ago I had wondered whetehr the under exposure of the K10D metering (and *istD before it) was in part down to UV. I never put a UV filter on the lens to do a 'before and after' scientific test....

K20D metering
Well, anyone has an IR cutter filter to try some flash pics? We know that reflections are a big problem with PTTL, so you just have to do a Before-and-after test with a flash, a reflective surface, and an IR-cut filter. If the pics are the same, then IR has no effect on flash exposure...

K10D & Telephoto
Regarding item 2, this might help: I don't know your particular telescope, but you can probably use a t-mount like the one I have shown on my Celestron. Regarding item 1, I have the a Tamron 70-300 macro lens (possibly the same type as yours), and get great results from it (IMHO of course :lo...

Shooting in black & white?
It is probably easier to think of it this way. When you were shooting BW film, you would think "this photo needs a red filter" or whichever colour filter you wanted to use to bring out the contrasts etc. that you wanted from the shot. With digital, you do not need those filters anymore. Think...

Disappointed with my K10D Today
All very well if its a single subject, not really feasable in a sea of faces during the start of a marathon where I want to pick my shot on the spur of the moment. Disagree. :) It gives you the best of both worlds without having to wait for the camera to AF as you shove the shutter fully down. I...
