*ahem* 77mm filter *ahem*...The SMC-DA 12-24 (which has a 72mm filter)...
I've been waiting 18 months to correct MM on one of his posts!
And I use the "wide angle" Cokin P holder on the 12-24 and it works fine down to about 14mm with only very slight vignetting below.

I got a genuine Pentax adapter from SRS - not worth bothering with the cheap copies for the sake of less than 20 quid, especially if the cheaper ones either don't work properly or get stuck on the camera.

I should have listed this sooner as the auctions finish tomorrow evening, but I have a load of miscellaneous gear on eBay right now. Not all of it Pentax but most of it is either Pentax K or M42 stuff.
Auctions finishing between 6.30-7.00pm tomorrow (05/02)
Thanks for looking!

Apertures run in the following order (largest to smallest):
f1
f1.4
f2
f2.8
f4
f5.6
f8
f11
f16
f22
f32
Each one lets in exactly half as much light as the one preceding it. Lenses like you 50/1.7 have a maximum aperture that is effectively f1.4-and-a-half. Add two stops to that will give you something like f3.5 (which is effectively f2.8-and-a-half).
Hope that helps!

If you're posting pictures to this forum then we tend to use pictures that are 800 pixels along their longest side. Hope that helps!

I prefer these to yesterday's - I like the angle a lot better. Very pretty stuff!

I don't mind the tilt on the glasshouse - it looks quite natural to me, but I do find the tilt on the playground a little disconcerting.

I wonder what they'd be like if saab built motorcycles?
It probably just about has the edge on mine in terms of acceleration and the ability to break sound barriers, but mine's a lot easier to park...
