If we are talking about inkjet prints then A4 would be a more likely size. If printed by a lab you could choose 12x8 inches, which is pretty close to full frame.

There is a choice. If you want the whole frame then you resize accordingly at 300ppi and accept that you will not fill some paper sizes. Just cut off the excess.

If you want to fill the paper use the Crop Tool and enter the size values in the top bar. When you crop, the image will be automatically resized and the image will be the same proportions as the paper.

You'll have to give the postman a key so the package and a nice cup of tea can be delivered at the same time.

Telephoto lens. Open aperture. Close distance. All this equates to shallow DOF, which is clearly shown in your image.

You focused on the bricks and the bricks are sharp.

I doubt it very much. You might find a confrontation if you were in a city centre, but again it's doubtful in most places. There have been some incidents where the Police have misinterpreted the law and tried to enforce non-existent regulations. Who knows why.

Just take your camera kit and enjoy yourself. I think the Freanch are quite used to seeing people take photos on the Normandy beaches!

True, the 16-50mm is weather sealed.

That would be me.

Also the 16-45mm is smaller and lighter than the 16-50mm.

Quality difference will be virtually irrelevant, only the stop difference in speed is really significant.

Well, bringing out detail and mist are sort of mutually exclusive, aren't they? Mist obscures and therein I think lies the problem. Can you have both?

Having said that, the composition is good. A nice lead in drops off into mist in the distance, which is also good. I would think more mist for me, but, as I said, it's your image.

1) Either will do very well, provided the used one is in mint condition.
2) Yes. Use A series or later lenses for most convenience.
3) Exactly the same.
4) At one time all new cameras tended to be supplied with 50mm lenses, so there are lots of them about.
5) The f1.7 will be better if you want to use it close up for document copying and to generally abuse it with add on lenses or extension tubes. The f1.4 will be better for low light work. But the difference generally will be minimal.

Hope that helps!
