Yeah, after the 1st 3 paras, was gonna ask about "mirrorless". Standard lenses have mirrors?! To do what?

The mirror is in the body of the camera, see image:

Thanks, B5. So the mirrors are just for the human eye.

I guess the image is actually recorded around the sensor/shutter region?

correct! the mirror reflects the view TTL -through the lens - to the eye piece.

from the link: "Mirrorless cameras do away with the mirror and use an electronic viewfinder (EVF) instead, meaning the image you see isn't what's being reflected through the lens. It's an electronic preview of what your camera sees. Some people prefer this system because it allows you to see the exposure change in real time as you change your camera settings while you look through the viewfinder. When the shutter is pressed, it simply opens to expose the camera's sensor to light and record the image."

And correct again, the image is recorded on the sensor. The shutter curtains lift up and expose the sensor to light, that's what images are, light. The main sensor sizes are 35 mm and cropped, different manufacturers have different size cropping. 35mm is known as full frame, or 1:1, and is in keeping with old 35mm SLR cameras. A cropped sensor is cheaper to manufacture, (MP is decided by the quality of the sensor, the better the sensor the higher the megapixels.) and usually not as good in low light situations due to less surface area. The canon cropped sensor gives you a 1.6 zoom factor, Ie if I shoot with a 100mm lens I'm actually shooting at 160mm, so for the footy I can shoot at 320mm with a 200mm (the max allowed) lens. This is also beneficial when shooting things like wildlife, motor racing, etc.

Nice. I never got into photography myself, but I do love photography exhibitions, especially of people and urban environments.

Haha nice! I can just imagine the smell of that landscape. Could you hear that waterfall or was it too far away? North America?? Rockies spruce and fir forest?

Speaking of landscapes, have you seen the show Hudson and Rex? Weak acting but we watch it to see Rex, the German shepherd, plus it's set on Canada's east coast, and has really got me wanting to visit.

^Fantastic. I know people in Vancouver and Halifax, so I've got both coasts covered. Defo one worth planning, I reckon.

Goodonya Jo,

All the tech talk about cameras remined me we did some stuff on Cameras back in High School science. I think it was Yr 8 before Science was split into physics and chemistry. Old late 70's cameras with actual film. We did some work on how the lenses worked, different shutter speeds and developed our own photos in a makeshift dark room and I understood none of it, despite being quite good at physics and chemistry.
