The system here is very simple. The seller offers something, buyers come forward if they wish. Items are restricted to Pentax related photographic ones.

This one started off badly with a poll, which really didn't serve much purpose.

The guidelines are at the top of the section.

If you don't like the seller's terms, you don't buy, and that is the single most powerful control, so it pays sellers to be as helpful as possible.

The I-10 is relatively thin on the ground now, but maybe Amazon or eBay will offer something?

When I used a camera with a horizon indicator, it didn't take long before I switched it off. The reason was that it was very distracting, in the same way that computerised readouts of mpg are in the car, and it distracts from the image.

I'd much rather have an unfettered view of the subject and concentrate on that.

When the K system was introduced in the 1970s a mass of lenses were released all at once. The same happened with the M system, A system, the F system, etc.

So it is possible. If being planned for a year or two ahead design and even tooling might be underway already, who knows.

I suppose it depends what the item is. In relation to a camera, it might mean a different power lead for the charger at least.

A good lens is really the one that fits with what the photographer is trying to achieve, be it a gritty architecture shot of a derelict site, or a soft, feminine portrait, or whatever else. So in this sense a technically poor lens could be a good lens.

When we were very young and just starting out in photography, a good lens would have been a technically excellent one, suitable fo a wide variety of uses. It morphs into other requirements once we develop a style.

I have a book from 1963/1964 called "Cameras" and it describes in detail everything on the market. Pentax lenses are described as, "High performance lens of critical definition at full aperture, high colour correction, and resolution."

Just for the record, the camera is described as, "Shutter accurate within close limits of engraved speeds. Quality workmanship of high precision."

You can make a DVD, but equally I'm sure you could make a Blu-Ray disc with the suitable hardware.

Some TVs will accept SD cards directly.

Nice lens Dave.

You can see the circular mark where the cap used to be.

Don't misunderstand me, it will be better, but only expect to see a subtle improvement at wider apertures and larger sizes. It will be your best option at a reasonable price.

Otherwise, it's the 16-50mm and the price goes up, again with another small improvement.
