don't know why you have not mod points. This is an insightful post..

Someone told me years ago that oil is a renewable energy source, it just takes a long time to renew...

Many years ago there was a discussion on the merits of all metal camera bodies vs polycarbonate aka plastic. Metal bodies dent and retain the deformation, possibly damaging internal components. Plastic would dent, but then bounce back to its original shape, thus protecting the same internals. for a portable device, ideally the case will absorb impacts and forces and then spring back to its original shape.

Anecdotal evidence... My Dad is in his early 80's and he rides a motorcycle all summer and skis all winter. He is more fit and more active than many half his age. In fact many younger people literally can't keep up with him on long hikes.

I understand he is an exception, and he is starting to slow down, but with something like people, you cannot put a hard number down a la Logans Run. For some people, like the grandparent above, 55 is too old, for others like my dad, 75 is too young (he was still active in politics, and maintaining his acreage, and volunteering with search and rescue at 75)

You must be going to the wrong bars and listening to the wrong radio stations. Either that, or the Canadian CRTC has a point enforcing local content on radio...

yes, a zoom lens is much easier to design for a small sensor. I really wonder how sharp an image you can get with a slow 1200 or so mm equivalent handheld.

There are 10mm lenses and 1000mm lenses, I would love to be proven wrong about a zoom lens from 10mm to 1000mm for a decently large sensor. And apertures for astronomical telescopes usually work out to fairly sedate f10. This lens has an extremely fast f5.6. PS a 10 mm eyepiece is NOT the same as a 1000mm focal length lens for "shits and giggles" Angeneux won an academy award for the unprecedented 12-120mm lens with an unheard of 10x range. Sorry, do your homework and learn the difference between a zoom lens and a telephoto.

now that was funny...

Yes, and I have still never heard of a zoom lens with a range greater than 16 times. Most film zoom lenses maxed out at 4X

I meant to say parallax, but you don't really understand either. Read farther down on the example of a chimney on a house.

Try this. Use a very wide lens, say 20mm on a full frame camera.

Bring the phone close to the camera so it fills the frame.

shooting edge on, and with the screen on top, tilt the phone up until you just see the screen.

You will not see the bump on the bottom.

or more blatantly, hold a coffee cup close to your face. Can you see the top and bottom? no. This is the same affect. or look up perspective especially single point perspective

oh for mod points...

But... but... he has a 26X Optical Zoom on his DSLR Whatever the fuck that means. If he really has a DSLR (Digital Single Lens Reflex) I am not aware of a zoom lens with a range greater than 16x (18-300) You do know that the multiplication factor means the longest focal length divided by the shortest. Or maybe he meant 26x magnification at the sensor plane, in that case, he must be using a crop frame sensor with an 850 mm lens (approximately) or more likely, a 500mm (mirror) lens with a 1.4x converter He spent all that money on photography gear and still doesn't understand perspective...

The US seems to have embraced the concept of "guilty until proven innocent" in a lot of their dealings.

This is one of the biggest problems with our education system. We tend to teach memorization rather than understanding. I read a quote somewhere recently, "Our brains are factories, not warehouses" yet we, as a society, tend to treat them as storage devices...

I agree with your post, but I am a bit concerned that your accounting skills need some work...

no, I only turn on my speakers when I want to hear something, like watching a video...
