I think the big jump in convenience from F to FA lenses was that the earlier F series had a macro setting for close focus whereas the FA lenses tend to have continuous focusing to quite close distances.

On DSLRs any Pentax lens can be used, but some are much easier to use than others.

Unfortunately I no longer have the K-5 so until I buy one I can't help. It is in there somewhere!

Use manual settings or set the approriate menu item to "release priority" instead of "focus priority".

You could argue that either way, but I would suggest that as we need SR these days we should compare what it would cost for us to overall get the same features.

That is, if there's any point comparing at all. A Pentax User needs Pentax lenses, so what Nikon or Canon lenses cost doesn't really matter.

That's fine Gwyn, but I had in mind those who, reading about this, will jump in and assume every mark is a manufacturing fault. They may not try the basics, especially if fairly new to DSLRs.

I use 200 ISO as standard, but when I get a K-5 I may up that to 400 ISO.

It would be a good idea to make sure some of these problems are not just sensor dust, before sending anything back anywhere.

It can happen that if items are returned under warranty and there's no fault, just user error, then people get charged. I'm not saying Pentax would, but some manufacturers have.

I've seen both extremes at the club.

There's the newbie who looks, listens, learns, practices and becomes dangerously good in quite a short time. And who continues to learn and improve.

Then there's the "early success gone to the head" who knows little, learns little but turns "professional" and stays at the the same dismal level for ever.

Two extremes indeed, but a whole spectrum of different learning curves between them!

The extra information is lost because it lies outside the ability of a printer to reproduce it. As a consequence, prints will lack the vibrancy of an sRGB print.

Now we don't know why your clients want AdobeRGB files, so can't comment on that. However, if your images are not displaying properly in Photoshop then going by what looks best isn't tackling the problem. Something is wrong and you can't guarantee the best results without knowing what is happening. Clients won't have a copy of the Pentax Browser. They may even be using windows to view the files, which will be an sRGB display.

When I view images using the Pentax software, Windows and Photoshop they look exactly the same each time.
