I would suspect that there's an advantage to alloowing the camera to do this. The noise will vary depending upong sensor temperature as well as ISO, and, being random noise, may well vary anyway. The camera will measure the actual noise at a particular time rather than an example of noise.

Perhaps the statement was written by whoever wrote the Pentax Lenses and Accessories booklets in the 1980s.

The favourite phrase for almost every lens was "the most versatile in the range"...

As for digital SLR beginners, it's quite right though. The perfect choice for familiarising them with the basics of using interchangeable lenses is to sell them ....an interchangeable lens.

Very interesting. A very high quality back screen. Dual power capability should satisfy all users. Very high fps. A back panel that looks just like my new X90, so moving from one model to another will be very consistent. The focus point indicators were inevitable.

Looks excellent and should help to take Pentax onwards and upwards with no problem.

This is quite an old item, and as Ken identified it is for mounting a camera on a tripod where the camera has no tripod bush of its own. It's more suitable for 1960s rangefinders and cameras of that size. The adjustment plate on the left allows the camera to be snugly fitted in and there are felt pads to prevent scratching.

There is a tripod bush in the bottom and one in the side, so the camera can be held horizontally or vertically.

It's bulky, looks home-made but isn't, and I had one of these once in a job lot of items. It sold for £5.00 on eBay.

Nobody should be in any doubt that the 240 V mains supply in the UK is deadly, although it is indeed the current that is the dangerous bit.

My Fraunhauf Induction Coil delivers voltages of around 10,000 V from a 4.5 V battery, and was used in the 1920s and 1930s for medical purposes. The current is very, very low though. In the 1960s the family used in for fun at parties!

As regards the batteries, people are not stupid because they choose a course of action different to our own. They have different opinions, and all opinions are based on their own perceptions and requirements.

The K7 batteries are larger than the K10D/K20D ones anyway, but as with anything else you get what you pay for. OEM batteries may not be cheap, but they're up to spec and as reliable as it gets.

A friend of mine gave me his GX20 to sell, with an assortment of batteries. The Samsung and Pentax batteries were fine, not a mark on them, but the cheap ones were coming apart and the labels had worn away to nothing as well.

I just think if a company thinks cheap in one area, it thinks cheap all round.

Generally, it was traditionally accepted that the "standard" lens for a format was the diagonal measurement of the frame. That is actually 43mm for the 35mm film format. Most standards for 35mm cameras have been long standard lenses, more recently 50mm but before then 55mm or even 58mm. This had more to do with the limitations of lens design than anything else.

Part of the problem may be the use of the word "better" - better in what way? Something more specific is needed than "This lens is better than that lens."

We could perhaps more usefully say "This lens has higher resolution than that lens" but whether overall it's better can be a different issue.

The Gallery was provided for just that reason - to make uploading pictures simpler. The forum though, like any other forum, needs links to images hosted elsewhere on the web. The easiest one to use is arguably Photobucket.

As for PU Magazine, we will have to wait for whatever information comes with the last issue. As we speak there will be lots of similar issues to resolved that are being worked on. It will all unfold in time.

If you want to post images in the forums, then please look at the instructions at the top of the Your Photos threads. Hoipefully Currys will resolve your problem - an exchange or refund would seem apprpriate.

Nowhere near that long. Our K10D/K20D batteries recharge in a couple of hours. In practice, we each have three batteries and one of them will last almost a week on holiday. On a wedding shoot one battery will last the whole event and not be anywhere near needing recharging.
