What do you mean by 'optical triggers'?

The Sigma 180mm EX DG Macro lens is a brilliant performer that I can happily recommend. It's near as dammit 200mm, faster at f3.5, and is a true macro lens. It is a lot bigger and heavier than the SMCP-M or SMCP-A 200mm lenses though.

SRS still have at least one in stock.

The K20D has a menu function to show you where the dust is on your sensor.

The Pentax sticky tape will not remove oil from the sensor, Eclipse 2 fluid will.

Don't forget you are not actually cleaning the sensor, but a piece of glass with special coatings on it which, amongst other things protects the sensor from dust. I'm not sure if it's oil proof though

Your decision negates your statement in your sig, "It's not the body, it's the lens".

As you've invested in a number of half decent lenses, changing brands just doesn't make sense.

If you think Pentax is a merry-go-round, your head will be spinning once you've moved to Canon or Nikon.

My brother-in-law bought a Canon 50D to replace his 20D. He sent it back within a week and went for a 40D instead. Canon seem to be in a race to cram as many Mp's into their sensors as they can, forsaking other important criteria like image quality.

Good luck, you'll need it.

The K10/20D and K-7 bodies are said to be weatherproof, not waterproof.

Weatherproof essentially means that they can withstand water falling onto them, as in rain.

When dunked in a bucket, the water at the seals is under pressure, albeit a very low pressure depending on how deep the bucket is, and the weatherproof seals might be compromised.

The deeper the camera goes into the water, the greater the pressure of water on the seals and the greater the risk of the water breaching the seals.

Bargain. If I didn't have two already, I'd have it.

James,

I'd call Chris if I were you. He could be busy today . . . selling all his stock of K20D's .

The rain must be heading south Jack. It started in Murcia about a week ago. I've been in UK since last Wednesday, and the weather is fabulous. Sunny, but cooler than home and a refreshing change to the 40+ degrees of our summer.

Personally, I think lens purchase is a lifetime investment. Buy the best for your chosen marque and they should serve you well for many years, even if they only get used intermittently. Bodies on the other hand, come and go.

Keep the 31mm lens, it's a gem, and wait for the K7 price to drop to around £400 - £500 in little over a years time.
