The same applies to EVFs, there's always a lag, making them IMHO almost useless for action shots.

On the other hand, there are lots of subjects where a screen is an advantage. No one camera fulfills all requirements, but the one that comes closest to being universal is the DSLR.

Jim's test chart is a bit different and looks like it has the potential to be really useful.

How about posting an image of it somewhere so we can see it?

Not in use. In the bag, the viewfinder is removed and stored separately. I still need a proper small leather case for that and maybe I'll go the the next camera fair and see what I can pick up.

The viewfinder is a superb piece of engineering. It is crystal clear, just like the best Voigtlander viewfinders of the 1950s and 1960s.

As I see it, it turns the Q into a classic reportage camera, not unlike an early Leica with external viewfinder but much quicker and easier to use. And with much better optics.

It may well be a price point, as I realise that sooner or later the K20D will have to be upgraded, so I may jump whilst it has the right second hand value compared to the cost of the new purchase. It could even be a zero-cost deal.

The reactionary response from many writers surprises me. In terms of camera design, has no-one ever seen a Kodak 35, an early Contax rangefinder, a Kodak Brownie Cresta?

The K-01 as a designed item (although all items are designed) is as valid as any other design. I think sometimes we get very stick-in-the-mud as photographers.....

Did it have a Dial Compur shutter Algi?

There will be a point where I can't resist a K-01, basically for use as a studio camera for copying and small product shots. On a tripod, using the back screen is a very effective way to set these up. I've even used the Q for this.

At the moment I use the K20D for this purpose, so I don't need another body, but it would be handy.

It might also be useful for flower studies - composing on the screen is an effective way of avoiding having to constantly bend my back to look through the viewfinder.

Benjikan has been using one.

OK, thanks.
