Matt, I think you need to double check the sensor dimensions. G

Focal length increase
Horrible though it is to quibble over 0.03 of anything, I'm with George on this one, using the dimensions that Matt's got on his diagram. The diagonal of the 35mm frame is 1.531 times the diagonal of the digital sensor. Just as it's 1.531 times the length of the sides too. Has anyone actually m...

Focal length increase
Since we're splitting hairs here, I thought I'd add my own piece... Lengthwise, the sensor ratio is 36/23.5=1.53191. Heightwise, the sensor ratio is 24/15.7=1.52866. Diagonally, the sensor ratio is ((36^2+24^2)^0.5)/((23.5^2+15.7^2)^0.5)=1.53091. So, chaps, however you wish to interpret it, ...

Cleaning The CCD
I am using the Forum for the first time so excuse me if this topic has been raised before. Despite being extremely careful when changing lenses on my *istDS I think my CCD is dirty. I have carefully followed the procedure in the manual but I still get marks on photos which are mainly visible on are...

Cleaning The CCD
I use an Actic Butterfly from Visible Dust to clean mine. I haven't yet had to use their wet system, but am told by others that it is very good. In the good old days when Pentax NL were in Breda they would clean it for free, but those days are gone. Some big photographic shops offer an expert clea...

Cleaning The CCD
Thanks Gwyn - will look into these products. Which 'big' photoshops were you referring to. I went into the main Birmingham Jessops and was told it needed to be sent away and would cost up to £100 - this seems escessive. Hi Impotentspider - where did you send your camera for the CCD to be cleaned ...

Cleaning The CCD
I use (rarely) Eclipse solution and lint free pads on a swab. Cheap, simple, works for me. A little practice is required to produce a smear free result though. The glass cover over the sensor is much tougher than some people (including Pentax) would have you believe. I had one camera where dust h...

Cleaning The CCD
I've used both the Eclipse/PecPad method and SensorSwabs (sp?) both dry and wet. But, in the end, dust will always get in there - even with rigorous cleaning - so Photoshop's clone & healing brush is extremely useful. (If you've been on ePhotozine at all and seen any of Keith Henson's work...

Cleaning The CCD
next week there is a cleaning workshop at a store here in the Netherlands. Perhaps I will visit it and see what they do/advise etc. But mostly I am with Matt, As long as I can clean it in Photoshop I don't bother cleaning it. I got a few spots on the CCD, but they only show up above f9 in a clear,...

Cleaning The CCD
I use the Eclipse solution and the Sensor Swabs. Seems to do the job, although usually a bulb blower gets the dust off first.

Seems like quite a long way to go, especially on a Friday in the Netherlands, you get stuck in a traffic jam and that's your day over...... Japan Camera in Waassenaar apparently cleans sensors for 25 euros.... Luckily Den Ham is in the east of the country so you travel away from the jams to get t...

nice thing is that I live in the east of the Netherlands. Den Ham is 65km from my home.
