The dedication module will almost certainly be for TTL operation (which your K10D doesn't have - hence it's of no use). Full manual control *is* useful as that makes it useable on pretty much any camera made in the last half-century (and a lot before) if you don't mind doing your own settings. If the head is of the tilt/swivel variety (allowing you to adjust the direction of the light) then maybe £15 isn't such a bad price after all...

Ahhhhhh. Thanks for that explanation. Makes a lot of sense. Well apart from the fact noise is random so how would you use a second file of just noise to cancel the noise from the original shot? I'm an experienced audio editor and I know that if you subtract noise from noise you get noise. What am I missing?
All else being equal (same camera, same sensor, same duration) then the noise generated by your sensor will form in the same way during both exposures - it may appear random (and you certainly couldn't use a dark frame from another camera - even if it was nominally identical) but actually it's quite predictable.

No more than about £2. Check the voltage with a multimeter before fitting it to your hotshoe (some old flashes have massive trigger voltages). If it offers manual control then yes, it'll be useable - just don't expect any form of automation or convenience.

Does anyone know if noise reduction is active on "B" or not? I'm not sure that these sort of cameras are best suited for exposures of many hours. The sensor might get very hot and noisy in that sort of time.
It certainly is - I've done 10 minute exposures with a 10 minute dark frame to follow.

If one takes a 3 hour exposure then it's highly ridiculous to have a 3 hour noise reduction processing time?
It's not "processing" anything per se - just taking a dark frame.

For example: Your 30 second shot will generate a certain amount of noise. The camera then takes another 30 second shot with the shutter closed. The second shot consists of noise only (the dark frame) and this information is then deleted from the first shot to make a noise-free image. It's quite simple but utterly foolproof and quite genius actually!

But no, it's a shame you can't turn it off in the K20D / K7 - but we K10D owners need at least one feature to crow about...

There is only one version of the DA16-45, Microglobe probably haven't updated their description since the launch, hence the "new" part. And Pentax's long-winded naming conventions often lead to small discrepancies in the ways they're listed from vendor to vendor. Welcome btw.

This is a seriously old thread!

I fear the only way you're going to get some examples of this lens on a film camera is by going out and taking some - it's not exactly thick on the ground and most who do own a copy would more likely be using it on digital rather than 35mm these days.

On a slightly different subject, I've noticed on old threads there are several postings from "Anonymous" and can't help but marvel at the join date of 01/01/1970 - twenty years before the www was born. Kudos for the forward planning!

That's very true - and one of the reasons I'm keeping my small stable of film bodies up and running.

He obviously didn't shop around like you did George.
