I take your point sterretge, but what I'm really asking is do we all realise that the 70-200mm that many see being used on FF cameras is already catered for in the Pentax range. The same field of view is offered by the 50-135mm.

I only ask because many of the photographers I talk to do get confused over the intricacies of focal length and format.

I'd take my 18-135mm. Not perfect, but very good results visually and very versatile.

SRS Microsystems are my favourite supplier, so worth checking out their website. They are a bit far away maybe, but they are superb in terms of service and, usually, price as well.

Amazon as Mike pointed out are a good source also, but do watch the wildly fluctuating prices. Sometimes expensive, sometimes incredibly good deals.

There are others, but also Jessops will probably get lenses in for you to look at. Alternatively, meet up with a fellow PU somewhere close by. Many will visit places near you, and no doubt we all have the lenses you want to look at.

I've noticed a few people mentioning a 70-200mm f/2.8 lens, which is a good lens on full frame cameras. The equivalent on APS-C is 50-135mm f/2.8 and Pentax have a superb lens already.

Do we really mean 70-200mm in this context?

Yes, I didn't realise how resilient the camera would be. We're already at the end of the fourth year.

Very subtle, but I prefer the first, it has slightly better texture.

Thanks Vic, I'll investigate that.

According to my iPhone it's 19C in Sydney just now, very pleasant.

So have a great day, but why not post some images showing us what Australia is up to today?

Some interesting shots there, going beyond the usual shot.

Eventually it would be nice if the camera could be cut in half so we could see what's going on inside. I'm not at all sure if that could be done cleanly enough though.
