But would there really be much sense in duplicating one here, when the Other Forum's one is fairly comprehensive (on Pentax lenses and modern Sigmas/Tamrons at least) and has a much wider pool of reviewers?

I was more meaning along the lines of Nikonians, i.e. access to certain parts of the site being closed off to those who don't pay. I didn't even know magazine subscribers had an icon here until this thread

Well, if they're bad enough for Pentax to spend a considerable amount of R&D money (something they aren't exactly flush with) on developing a completely new focus motor I'm not sure that it is harsh to be honest.

Warehouse Express have them in Canon mount too - makes sense for Sigma to get them out to their biggest market first.

I knew there was something I'd forgotten about the FA77 - and the PF is probably its biggest 'flaw'.

Also, in saying that the Sigma has SDM you're missing the vital point: that Sigma's HSM doesn't have the crippling reliability concerns which sunk Pentax's SDM.

I think of the two I would probably rather have the FA77 too, purely because of the "wow factor" - it seems to be a thing of beauty both in its images and mechanically. Still, with the cost of either of them and the fact that I just ordered a lens it isn't a dilemma I need to pay too much attention to in the near future

At least the NX10 is APS-C though (upgraded K20D/GX20 sensor in fact)

That should put it in about the same price bracket as the FA77 by the time it gets over here. The Sigma has the obvious advantages of speed and HSM (and quickshift?), while the FA77 has tactile quality, compactness and pixie dust. Assuming that the Sigma doesn't FF horrifically like their 50 f1.4s did, it could actually be quite an interesting matchup.

Pentax also wins on modesty

Happy Birthday Gwyn!

EXIF data is automatically embedded in the picture when you take it - so unless you've specifically done something to take it out, it's there (it isn't visible on the image itself).

Well I finally bit the bullet and ordered the Limited. The New Lens seems very good indeed, but this is as much an emotional purchase for me as one based on photographic qualities: I've had my heart set on the Limited for some time and only doubted it because of the cost and slight speed advantages of the New Lens.

PS: For the avoidance of all sorts of 'DA35' confusion (were Pentax marketing on vacation when that name was agreed?), this pair have officially been rechristened The Limited and The New Lens.

If it's based on the FA35, take a picture of anything with reflected sunlight involved

MF is the answer I'm afraid, either that or put the feature in question (eyes or whatever) directly on one of the AF points.
