Congratulations, Chris.

As long as there is no flange preventing the lens seating itself on the mount on the body, you will get infinity focus.

I removed my metal strip to facilitate removing the adapter. As you say, just be careful not to unscrew the whole caboodle.

G

You've asked that already!

Good. I purposely said "people" rather than "you" because I was not aiming my remarks at you; my intention was to forestall yet another intensely boring full-frame discussion, of which there have been far too many.

[quote="stevejcoe"]There isn't a hope in Hell of a full-frame sensor in a Pentax K-mount camera. With the exception of two macro lenses, all new Pentax lenses are designed for a reduced image circle. Almost all old lenses have been discontinued, save for the Limiteds and some specialist lenses which are built to order.

Coming up with a new, pro-spec (as it would have to be) body with only half a dozen lenses is not going to work, and it certainly wouldn't be worth Pentax's while to produce a full line-up of full-frame lenses which would sell in tiny quantities and therefore be enormously expensive.

People who think there will be a full-frame K-mount Pentax are seriously deluded and, frankly, not very bright. Sorry to be blunt, but the facts are very clear. Wishing for something won't make it happen.

G

I thought you knew what was coming.

The other two are fair enough, but why slots for two different types of card?

A denser sensor is almost a certainty. Manufacturers will find ways to cram in more pixels without compromising quality, and that is why a "full-frame" K-mount Pentax will never happen.

£400 for the K100D Super. £450 for the K10D. No contest.

Good grief. How often do you take your camera for a swim? In 50 years of owning a camera I've dropped a couple but I've never immersed one. The ability to recover pictures from a sunken camera has never seemed to me to be an important selling point.

It was a Pentax lens, just not a Pentax-M as you originally thought.

Before the K-bayonet, Pentax cameras used the 42mm screw-mount, and the lenses were called Takumars, after the chief engineer at the time.

The company was originally called the Asahi Optical Company, but it changed its name to Pentax after the Spotmatic camera bodies made the name Pentax instantly recognisable.

Sadly, and stupidly (because Takumar lenses were revered for their optical and mechanical quality) Pentax later devalued the name by applying it to cheap, uncoated bayonet lenses.

Try rotating the focus ring on the Takumar lens. If it's still in good condition it will turn with a silky smoothness that modern lens makers can only dream about.

It's worth having an old Spottie just to turn the focus ring on the lens occasionally.

So if it's OK, and going for a song, get it.

G

As far as I recall, Spotmatics came with either a 50mm 1:1.4, or a 55m 1:1.8.

Possibly it was a non-Pentax lens - perhaps a Zeiss.

Of course, this being Australia, the home of resourceful, DIY types, perhaps the owner had removed the bayonet mount and machined himself a 42mm screw-mount. But I think it's unlikely.
