It could have been handled a lot better on both sides, although that doesn't excuse the police talking of knocking people out.

That female voice must be why I let here guide me when I already know where I'm going. A bit sad really.....

They have a style about them, and getting in close like you do means a very intimate connection with the event.

I find some of them, especially the black and white ones, a bit over-sharp though, with a grainy effect that's almost like reticulation.

So in general I prefer the colour shots.

We still use maps for surveying an area for places to visit, but then program the SatNav for the actual journey. So far, she has selected the best route every time, even the little known ones that locals might use.

When we come home though I deviate to my favourite route and after a few seconds of "turn around when possible" she adapts very quickly and takes me the way I want.

Ring lights are usually supplied with adapter rings, so if you don't have the rings why not try SRB Griturn who make all sorts of rings and adapters.

That second look can be quite valuable as we get a chance to see the images in a colder light, long after the first flush of excitement makes us select the initial few.

There's more to lenses though than resolution tests. of the three Limited lenses I had, I eventually kept the worst performer of the three, the 43mm f/1.9, because I liked its overall rendering best.

Why didn't I keep the 31mm and 77mm? Limited funds at that time is the simple answer and although I'd bought a number of lenses as a bulk buy the others had to be moved on. Reality of the moment.

Yes and no. A 50mm lens is a 50mm lens regardless of what you put behind it, so the DOF doesn't change.

However, on APS-C you are getting the same depth of field with a moderate telephoto lens as you would with a standard lens on FF. The APS-C camera therefore delivers more DOF.

Looked at in reverse, to get a standard view on FF you use your 50mm lens. But for APS-C you use a 35mm lens and therefore APS-C delivers more DOF.

Bigger formats give less DOF, the smaller the format goes you get more DOF.

At the extreme, a Minox "spy camera" uses a 15mm lens to give the field of view of a 50mm on FF. We know 15mm lenses have immense DOF, so the Minox can be fixed focus and give DOF from about 9" to infinity at open aperture.

Well good luck with it, you have far more patience than I have. Once it's done of course that will be a Very Good Feeling.

I hope you've backed them up!
