lens care
Personally I don't use filters for protection, some here feel the same way, others don't. If you're going to use them, then it makes sense to buy the best you can afford. If you have the lenshood fitted all the time, it will protect the front element of your lens from knocks and scrapes much bette...

Hi dan the reason for the cimco teleconverter is i bought it on ebay for £7 and its mint .The reason for the 24-51mm on a cropped sensor is because dg lenses are compatible with 35mm film cameras and therefore the focal length changes on a digital sensor and the reason.I havnt done this for the macr...

lens care
I do put filters on the front of all my lenses, The reasons are as follows: 1) My bag isn't big enough to leave the lens hoods on permanently. Have you seen the size of the 50-135mm one? Also, the hood of the 12-24mm looks a bit fragile for that sort of treatment. 2) I am cack-handed and am alw...

Infra red filter?
To quote John; The K10D was poor for IR and we can see why. The K10 and K200 share the 10meg sensor, so... Do the other cameras I have share a common make sensor, perhaps Sony? Which would explain why they see more IR. :wink:

my K110d and a R72 filter should allow me to play in the IR Correct. Your K200D might produce similar results but would require much longer exposure times. By replacing the sensor's filter with plain glass, handheld IR is possible as the exposure times are dramatically shortened.

Infra red filter?
I've learned a bit more about IR conversion since my last post here. The cameras filter can be replaced by an R72 (IR) filter so that you can use the viewfinder/metering normally, but only IR light reaches the sensor. It is also necessary to move the sensor rearwards during this conversion to cater ...

The alternative to moving the sensor is to use an old manual lens which has a small red mark on the focusing barrel which is the offset for using IR. It appears on Super Takumar, Takumar, M and A series lenses. I don't have any F/FA/FAJ lenses to check... Best wishes, Kris.

Had a problem the last couple of days with spots in the centre, and outlying areas on shots. Took a really hard look at the sensor and couldn't see anything. I bought the pentax sensor cleaning kit and gave it a go. All spots gone. Couldn't believe how well it worked, considering the sensor looked s...

I used the Pentax Kit O-ICK1 with success on my *ist DS sensor. Me too, on a K110D. By the way, I love the name of this kit. The first time I saw the crud on my sensor I said "Oh ICK!" :P

Price of pentax equipment in Japan
Hi all, Just wanted to say that the strength of the Yen really isn't helping the price of equipment in Japan. I was hoping to pick up a DA* 16-50mm while on holiday in Japan, but in a good, competitive, store in Tokyo, it was twice the price of SRS. For what it's worth, I'd wholeheartedly recomm...
