That's excellent news. I had two of the original Spotmatics, always fancied the F model, but never got around to it. Terrific price

It might have been a new design although at £144 it would have been more likely a facelift. The heavy Chinese made K1000 was still on sale for £119 and the cheapest AF body was the SF7 at £239 and that wasn't a very high spec. camera.

The MF market wasn't in very good shape at the time. Olympus had stopped on all but the top model. To compete Pentax would have probably had to sub-contract the camera the same as they did with the 28-80mm lens that they included in their "We must be touched" advertising which referred to them selling camera and lens cheaper than anyone else on the market.

Prices from Fishwick Catalogue 1990-91

You also need to test with KA tubes that the minimum aperture is being transferred from the lens correctly. i.e. with say an f/1.7 lens you should only be able to set down to f/1.7 on the dial. If you can set f/1.4 something isn't connecting.

Mirror flipping is when the mirror bounces up and down two or more times instead of once. Quite rare.

The T (Titanium) just referred to the colour of some of the plastic on the body apart from that it was identical.

They kept the list as small as possible by not including variants of models which were almost the same.

The repair manual for the P30 can be downloaded from.....

This could possibly be compared against a repair manual for one of the other models to see if the internals are similar.

If the aperture isn't showing on the top screen.... something isn't working
At best the metering will be a few stops out. It can also cause mirror flipping.

Just checked again on the K-5 and it doesn't show on either screen with a Jessops painted tube. Removing the paint allows one of the pins to be shorted out. They can all be shorted out and it will work OK.

The list of Cosina made cameras came from this group of reputable collectors.......

All the Jessop one's I've seen need scraping. You must have a set that haven't been painted black next to the contacts i.e. silver.

It is a bit odd that they call them KA when a contact from the body is missing.

Same tubes are sold under other brands such as AICO.
