Hi Miro, (and BC & Wim)
Actually, I have got the answers I wanted, thanks to Wim, BC and others
As I said earlier, Wim, the links you provided were just what I was looking for...
Some of the difficulties which triggered me posting this thread are related to how I view the images... they look reasonably sharp at 1200 pixels wide, but they aren't tack-sharp where I want them and I see that clearly at 1:1.
And as I also said, this is partly also related to the fact that I know the autofocus on my camera has become unreliable, so I wanted a rough idea of the aperture I would need to use to ensure a given amount of leeway. I hope I won't need that when the camera comes back, but it's still useful to know, nevertheless.
Now, thinking about the antagonism that gets into some of the threads here at PZ from time to time and which I guess I've found as off-putting as anyone else - I specifically asked that it be avoided this time...
And, actually, though the tone between BC and Wim could be seen that way, on reflection I don't think that's what has happened this time. And, certainly, I don't think any antagonism has been intended. You're debating points of view that you believe to be right, and the way you express that sometimes gets quite passionate and, particularly BC, quite strident and robust (e.g. the CAPITALS - perceived as shouting on most internet forums).
BC, both your simple equivalence calculation (aperture and FL equivalents can both be approximated by multiplying by the crop factor) and, Wim, your - as usual - more technical, erudite, explanations are very valuable and helpful here - as well as the input from VL, Serkan and others.
Incidentally, I'm looking forward to having a lot more time for practising photography in a few months, rather than just grabbing the occasional day every few weekends (lucky me!)... one of the things I'm planning to do is to take a weekend workshop or two in landscape and portait photography... found a photography school fairly close to where I live: [url="http://www.photography-courses.com/"]Blackthorn Photography Centre[/url]
Best wishes,
