Posts repeating the same thing have now been removed, we are not going for an endless argument here over something so minor. It puts a lot of people off posting and it's not necessary.

I think well done Dan for getting a review published. You've got the experience to do it justice and you should be congratulated on a job well done.

Fair point malcolmk, some makes may just not get on well with Pentax cameras.

No doubt there is a list on the Ricoh website somewhere specifying which cards the cameras have been tested with.

Lens design has been turned on its head by different types of high refractive index glass, aspheric elements, low dispersion glass and so on.

If the new converter only needs 4 elements, then so be it. The proof of the pudding....

A very nice, pleasant and calming image.

It would be appreciated if you could post in English. It is possible to use Google Translate if you need to.

Percentage scores can be based on detailed lists of things that add points to them, for example with value you could compare a set number of parameters of features vs cost of features. Such lists are in existence, although I don't know if this particular review used them. It's not necessarily as random as it's easy to assume.

However, I agree that scoring systems are a bit dubious at best and useless at worst. That does not negate the value of a review though, it's something that's there in reviews because the audience demands it. Or at least a large proportion does, because people are looking for a "top trumps" reason to say their camera is better than mine, or maybe a quick summary to aid a slightly casual buying decision.

Ridiculing a review because it has a scoring system seems to me as silly or not as the scoring system. We understand why it's there, don't we?

I've changed the title, but a picture might be helpful.

An M lens will only operate at full aperture unless "use of aperture ring" is set to "permitted". Then you need to manually stop down the lens. All auto modes will work in Av regardless of settings, or you can use manual exposure.

Have you also set the camera to manual focusing? Otherwise, perhaps catch in focus is not letting you release the shutter because the focus point is not spot on.

If you are using very long exposures, perhaps you are not waiting for the camera to finish its dark frame subtraction? If you take a 30 second exposure, for example, the camera takes a second blank 30 second exposure and checks the noise pattern from this, which it then subtracts from the main shot. You can't shoot again until this process is complete.

The one time I went in it became obvious they have a two tier price system, so be careful you say what price you want, that is, the advertised price as opposed to a shop price.

It certainly is a mystical effect, quite glorious. I expect those who live there eventually get used to it, but it's something I would like to experience first hand.
