A quick eBay 'complete items' search suggests that these normally go for between £75-100 without the 1:1 extension tube. I imagine the tube would increase that significantly (they're rare apparently) as would the adapter (which is only slightly less rare).

I'm surprised there hasn't been a rush of FA*85 price scalpers getting in before the Sigma 85 is priced and dated.

I've phoned them a couple of times* and they seem genuine - to be fair to them, the cheap lenses all disappeared from the site around Friday and would now appear to have been re-added at the new prices. It isn't so much a bait-and-switch as a failure to appreciate just how spectacular Pentax's 2009 price hikes were (almost their entire Pentax range was listed as out of stock for months).

*To do with the actually-existing old price 12-24s. I ended up missing out on one by a couple of weeks, but I'm glad I did since I love my (SRS-sourced) Sigma 10-20 so much!

People who regularly photograph indoors and outdoors, and therefore need both weathersealing and good high-ISO performance?

Cheers - guess I'll just have to be sure to buy a strong enough grad!

I've read in various places (famous last words!) that it is possible to use Cokin P size (ie 4" x 6") ND grad filters with a 10mm lens so long as you use the single-slot wideangle holder. Is this true? Don't want to order a set of them and then have it not work! I know about the colour cast issue with Cokin filters: I'm planning to buy one of the other brands of Cokin P size grads.

Hey, a catalogue is a specialised piece of equipment, requiring extensive health and safety training to use appropriately!

I got my Sigma in today, and although I don't have anything postable yet (my test shots are of my house complete with street sign in front - not something I'm posting online ) the images it produces are fantastic. The build quality is fantastic, and the EX finishing style (gold stripe plus it sparkles!) is really lovely. Thanks for the help folks!

That would kinda give the game away I think!

It's not just accuracy, I'm fairly sure there is some aspect of their design which makes the colour change slowly (but constantly) over time. However, what I know about monitor technicalities could be written on the back of a postage stamp with a board marker!
