Checking sensor cleanliness
I was so worried I had to go and have a Large G'n'T! If I photograph the wallpaper, can I have a G'n'T :D

Checking sensor cleanliness
I always remove the lens select B mode and take a picture of something white (white computer screen) move the camera while taking picture to ensure that only dust on the sensor screen shows up

I assume you're kidding? Surely removing the lens while the sensor is charged is a sure fire way to attract dust? Mike

Checking sensor cleanliness
I use the smallest aperture, defocus the camera and aim at a white wall or ceiling, and make sure my hands are nice and unsteady on a long exposure . That way I know anything I see is on the sensor.

advice needed please
WD40 is a known rubber solvent, it's often used in certain circles (airsoft and paintball, for example) to swell the rubber in valves to help with airseals, but at the potential long term expense of the seal. Also, Silcon lubricants and WD40 are designed to leave film behind to lubricate the surf...

advice needed please
I dry wipe my lenses and K10 with a soft cloth. If you are getting a build up which needs cleaning regularly is the lens a good fit to the body? Any movement at the joint could cause a problem. The electrical connections are low voltage/current and need maximum cleanliness and absolutely nothing mus...

advice needed please
A microfibre cloth should work fine. The act of mounting/removing a lens should also have a cleaning effect on the contacts.

Which A3 printer?
Hi Steve In my experience any inkjet printer will suffer from blocked nozzles if left a while. They all have print head cleaning routines in the bundled software - of course that uses even more ink. :wink: HPs designs used to build the printhead and ink cartridge into a single unit - maybe the...

Are You Satisfied
Mind, if we didn't upgrade we would be stuck with .3mp point and shot things mind you some 3mp pixel point and shoots are better than todays models. I still have a Canon S30 :oops: from 6 years ago. Tv Av M modes ISO down to 80 and shoots Raw. I reckon a Ricoh GX200 must be the closed point and shoo...

Are You Satisfied
So you would say from K10D to K-7 is a major step? Definitely. Especially as you're going from a CCD to a CMOS sensor, the differences in the way they render are significant. The K-7 also offers quicker AF for screw lenses if that's something you need. I used my 500mm on the K-7 and it felt almost t...

full frame v crop....... numpty question maybe or not.....
Ok, am a member of a few digital photography forums and there seems to be a lot of debate on full frame or crop and i want to make sure I fully understand......... Have a penty K-m and believe the APS-C sensor has a crop factor of 1.4 - my understanding of that is that a full frame camera would c...

full frame v crop....... numpty question maybe or not.....
First of all you got some bits wrong, sorry to start with that. For APS-C sensor every company use their own sizes but all are roughly the same. Here are the crop factors for APS-C cameras. 1.6× — Canon 1.54× — Pentax K20D, Pentax K-7 1.53× — Pentax (the rest) 1.5× —...

full frame v crop....... numpty question maybe or not.....
Personally I cant see what all the fuss is about over full frame sensors, as Stefans example above clearly shows there is not a lot in it, in fact APS-C could have a slight advantage for those who shoot landscapes in that it offers greater DoF in like for like shots. DoF increases as focal length...

full frame v crop....... numpty question maybe or not.....
Perhaps someone can explain this better, but I read somewhere that when you use a 'full frame' coverage lens (as opposed to one designed for the smaller PS-c sensor) on an APS-c sensor you benefit from a potentially sharper image since it is only recording the light from the central part of potentia...

Also what I had noticed, although I am not sure if this is due to the direct relation to full frame or not but when I tried the same 200mm range lens on a D300 and D700 the AF locking speed was much faster on the FF body. I was told that its because the FF sensor had more light falling on it so it w...
