Lens cleaning paper - thoughts?
Methylated spirit has additives (pyridine?) to stop people drinking it though as Petrochemist says methanol is toxic in it's own right. IPA comes in differing purities/cleanliness depending on the application and price. I suspect his is ultra clean and/or filtered by the equipment that spray the ...

Lens cleaning paper - thoughts?
For Methanol I did mean Methanol rather than Methylated spirit. We use laboratory graded at less than 0.05% impurities. IPA or Isopropyl alcohol is also a useful substitute. (The other type of IPA is a useful substitute for ESB!!) As for silvered mirrors - the best advice is no contact at...

Your best tips for a DSLR beginner?
My tip would be to try and value. This controls the amount of light that gets onto your sensor, your shutter speed and also depth of field. There is/are a lot of jargon/technical terms related to DSLR photography. They can seem confusing and intimidating to the uninitiated but once you get your ...

Your best tips for a DSLR beginner?
And from me: :) Ten tips to get you started - * Work through the manual with camera in hand - explore every setting, option and menu. The camera doesn't bite - get to understand it. * Av (Aperture priority) will let you set the size of the aperture to control both the amount of light rea...

K-r - worth the extra over K-x?
I'm giving serious thought to a body upgrade (no, not mine, the camera!) :lol: I think I'll be able to afford a K-x and quite fancy one of the beige ones (forget "boring beige" associations, it reminds me of the rare "safari" version of the Auto 110), although I don't really want another 18-55mm...

K-r - worth the extra over K-x?
The other thing I considered: Will the K-r work with Power Zoom? I know the K-7 will as Dad took great delight in playing with that and the PZ 28-80mm I lent him to go with his kit lenses. I suspect it might but would want a confirmed report. I realise this is a slightly odd thing to consider but I'...

Pentax Mirrorless (or is it?) small interchangable lens camera
Look at this rumour as Pentax are about to announce a rival to the G-system, NEX, NX and Pen camera. http://www.43rumors.com/category/rumor/ Well, it is not a surprise, as for money generating, these CSC cameras are where the makes need to be. (Nikon are also rumoured and have patented a syste...

M42/K Mount adaptor on K-x?
Comments on a couple of non-Pentax brand M42 adapters. My wife and I used to use Spotmatics a lot. When we decided to go properly digital we chose the Pentax K-x in the hope that we could use our old Takumar 42mm screw-in lenses for odd occasions. I am well aware of the strong recommendations...

K-5 out of stock?
I was trying to purchase a K-5 yesterday. And I found it was out of stock everywhere, even SRS. Cameraworld has 2 in stock but I found they all had sensor issues. After a whole day searching, I bought a K-5 in Jessops but then I found it was not a new one with 11 activations. Does that mean Pentax r...

K-5 out of stock?
11 activations is normal for a new camera- especially one which has had it's sensor checked. The K-5 is proving to be an incredibly popular camera and Pentax are working hard to meet demand. The sensor issue affected availability a bit but not much I think.

K-5 out of stock?
I've seen a statement from Pentax somewhere that camera's are supplied with 0 shots taken and it can't be reset. Some dealers are probably testing for sensor marks. I would throw it in the bin if it had 11 activations on it and buy another :shock: :lol:

Pentax K20D fault at low temperatures
You may be suffering from a sensor fault that seems to occur in some Pentax K20D/Samsung GX20 cameras. At low temperatures pictures can suffer from lines, magenta shifts and posterisation. This happened with my Samsung GX20 camera. At temperatures below 10C I intermittently suffered from the abov...

K7 - Worth It?
It is a tough one to answer. I did look at the K-7 before I got the K-5, due to the fact that although my K20D was getting on a bit (nearly 3 years old and over 30000 shots), would the K-7 give me much more than my K20D (apart from better AF and shutter) The reality, for me, was that, although th...

K5 shake reduction in movie mode: on or off
The shake reduction is a great help for hand held video. It really damps down jerky movements - you can see it working as you shoot, through the lcd. You would want to turn it off for 'panning' shots, as the sensor will try and cancel out the camera movement and cause a little 'lag' at the begin...

pentax kr internal movement???
The sensor moves as part of the shake reduction system and you may be hearing this movement.

pentax kr internal movement???
It's completely normal. The sensor is held in place by electromagnets around its circumference - that's how it compensates for shake. The shake reduction only kicks in at the time of capture so the rest of the time the sensor is free to move within its "cage".
