In what way is it not working very well? A good first step would be to do a focus test to identify exactly what the problem is. Download a focus test chart - the one on www.focustestchart.com is the best - and follow the instructions. Using a tripod helps if you have one.

Then post the resulting images on here, and someone should be able to identify the problem.

How did you guess it was the D7000? In my case it wasn't so much dissatisfaction with the AF (OK, it's not great) but a desire for some fast glass - the AF of the D7000 was just another 'pull' factor. I was always reluctant though because I'm very attached to my gear, and then I worked out that switching to Nikon would actually cost me more than the lenses on my wishlist and that was that .

I'm normally very reluctant to make any law-related comments on forums, but I can't resist. Any authority they have under s.112 of the Civic Government Act is subject to ss.3 & 6 of the Human Rights Act 1998:

[quote="s.3(1) Human Rights Act 1998"]So far as it is possible to do so, primary legislation and subordinate legislation must be read and given effect in a way which is compatible with the Convention rights.[/quote][quote="s.6(1) Human Rights Act 1998"]It is unlawful for a public authority to act in a way which is incompatible with a Convention right.[/quote]So their statutory powers must be interpreted and applied in a Convention rights-compatible way, and they may not act in a Convention-incompatible way.

Does imposing these draconian restrictions on photography in a public place violate any of the Convention rights? (most likely art.10 freedom of expression) Somebody probably knows but I don't, since I'm not a human rights lawyer or a human rights scholar.

Well I thought I'd post in here (despite not being new to the forum by any means) because, after coming very close to switching to Nikon, I've changed my mind and am sticking with Pentax. I just love my Pentax kit too much, having lovingly assembled it to fit my interests - plus the money it would cost me to switch could buy some nice glass WITHOUT the sadness of changing systems. Does this make me a born-again Pentaxian?

EDIT: Decided that I'm staying with Pentax after all. Just couldn't bring myself to part with my beloved Pentax kit

Would just like to point out my prediction a few months back: that if a Pentax FF DSLR ever happens it will be an EVIL

Is one modern implication of this (ie excluding "old lens BA") that the D7000 will meter with the Lensbaby while the D90 will not? I suspect there are more potential Lensbaby buyers in Nikon's flock than there are potential old lens buyers - how much of the 'advantage' of using old K-mount lenses on Pentax is really mitigation of the lack of budget lenses?

Depends what your use is. I take a lot of indoor shots, and at f2.8 (my 50 Macro) I need ISO 1600 and a 1/20 exposure for some of them. These shots would probably have been impossible at f4 (as it was only SR saved me!)

So you need to ask which will be more useful to you: the ability to go to f2.8 for shutter speed/DOF reasons (even if the 28-70 isn't great at f2.8, it is better at taking f2.8 shots than the 17-70 is!), or the advantages of the 17-70 (cost, weight (!), extra width)

I have the M42 equivalent of this (77M-4) and it isn't razor sharp but is decent and also has lovely bokeh. One thing to bear in mind is that mine has an aperture pin which has to be depressed in order for the aperture ring to work: a bit of loctite and a small fragment of AOL CD soon sorted that though
