CSC is the term that the manufacturers and various publications are settling upon to refer to Compact System Cameras.

Personally I would stick with the 50-200mm until I could afford the Pentax 55-300mm. This is available with a metal mount, or at a lower price as the DAL lens with a plastic mount.

It's an excellent lens.

It's a great lens.

Pentax has a superb history of being backwards-compatible so I'm pleased to say all your options 1 and 2 are fully achievable.

Option 1 - Look up Harrow Technical or Asahi Photo and both will be happy to help you with overhauling older Pentax items.

Option 2 - The A series lenses will be fully functional with all Pentax digital bodies. Obviously no AF, but set the lens to "A" and everything will work normally.

Cureently we have the K-r and K-5 to look at, so check out prices on www.srsmicrosystems.co.uk who are our main Pentax suppliers here on the forum. Also Park Cameras and others can supply Pentax.

I'm removing your e-mail address. It's a bit unwise to publish it on a forum as you will find the spammers find you very quickly.

Chris, your opinions are fine, but there's no need to be downright rude and aggressive with them. A bit of courtesy goes a long way. People tend to reject aggressive stances and then any message of value does not get through.

Actually, the latest report in AP said that the growth in CSCs had stalled and that the DSLR market was more profitable.

I think the others are talking about the US Pentax Photo Gallery, hence the confusion!

I think Chris may be looking at the Pentax User gallery page?

The magenta hue can be corrected by reducing magenta in the printer software. I use -7 magenta for my Epson printers, which is just about right.

We don't usually allow links to eBay auctions, unless they are Buy It Now. In this instance, it was used to illustrate the lens that was desired, not to point to the auction as such.

If someone can find a better link to the picture of the lens I'll happily remove the link. As a principle, eBay links are best avoided unless in Leads to Deals as a BIN.
