Sony & Nikon & Canon put out 600mm prime lenses in the $13,000 range. I can get a Fujifilm or Tamron or Sigma 150-600 mm lens for $2000 or less. I would love to see the same distant object taken at 600mm with one of the primes and one of the lesser telephotos at differing levels of cropping to see the difference in detail/sharpness. Any website show this or does someone here have such photos? I am not expecting a dramatic difference as I understand you pay a high premium for incremental improvements generally. I am not planning on any $13K purchase (unless I win Mega Millions lottery), but just curious.

lol... I know. Technology changes they way tools are used, if at all.

I use my pocket computer to: talk, text, know the weather prognostication, check my calendar, photograph, write Yelp reviews, get an Uber/Lift, facebook, instagram, tweet/thread, get CVS medication notifications and etc.

It's true I am not a professional photographer and kudos to you if you are.
When I started taking pictures and developing B&W pix in 1970 very few people carried cameras. Photographer filled a niche. Today EVERYBODY has a camera. Today celebrities with millions of followers have their images seen within minutes. Ansel would be envious.

Smartphones are here, that's clear. Deal with it.

Well the war was based on an event that did not happen based on a theory that C*******m was so attractive and powerful that all the countries in that area would fall like dominoes. Was Jane an "American T*****r" or an activist against a horrible war that was based on paranoia and the imaginary. "I had the best seat in the house to watch that event and our destroyers were just shooting at phantom targets—there were no PT boats there . . . there was nothing there but black water and American firepower."

According to a friend who is living in the area Nam, Cambodia, Indonesia, the life there is pleasant and open, and so much safer than Miami and a hell of a lot cheaper.

It is important to view the past and the now and forecast the future with clear thoughts. Conservatives are renowned for conserving mental energy rather than clear objective thinking which requires changing old views. To MAGA they want to go back to the past... the imaginary and to some degree real Great Times in the USA.

PS: do not label me for disagreeing with "tradio"... Yes, my thinking is distorted by education; Science, Math, and worse of all Philosophy and Psychology courses.

President Jimmy Carter's brother, Billy Carter, was a big issue, he drank too much beer. That was used against President Carter. H****r B***n's lap top is as important as Billy's beer. H****r's "sweet heart deal" is an example of crime that is too trivial to pursue when houses [of congress] are burning kindled by top secrete papers shared with foreign powers by trump. H****r is a diversion from the big story, Trump.

Billy and H****r remind me of the foolish Prodigal Son story: A son asks his father for his inheritance, then squanders it recklessly as he lives a life of indulgence. With nothing left of his fortune, he is forced to work as a hired hand for a pig farmer.
Luke 15:11-32- The Parable of the Lost Son

In this case the inheritance was the example and guidance of a successful father. Squandering was the drug indulgence of the son. Money crimes are so trivial compared to Trump's selling out USA for money and fame to feed his ego. What is on the laptops of all the republicans and their sons????
