Moderately better image and other benefits

Well, I always like to know that I am in fact upgrading. Like I said I bought and sold a lot. On the telephoto side I have had two 300/2.8, two 400/2.8 and throw in a 200/2, 300/4 and another 400. Before I sold the last 400/2.8 I had to be absolutely sure the 800/5.6 and 300/2.8 could replace it.

This past year I compared my 4 ultrawides carefully before selling the one that was not up to snuff.

Of course all these lenses are ridiculously good but I always like to know where they, and I, stand. Lens testing goes a long way to help. I sure don't need to test this set now, just keep shooting.

When a new arrival shows up in a week or so, I will pit it against the ultrawides to see how it fits in.

i just can't understand why buy a lens in the first place if then turn around and sell it...and then buy it again   i have collected about 12-13 "L" lenses, 2 zeiss lenses, and one sigma 150mm macro lens in the last 15 years. every lens i purchased, i'd wait and contemplate for 6 months, average! i wanted to know why i am buying it, for what occasions, would it serve the purpose the way i want it and what are the alternatives and so on. and then if all of the boxes were checked, i'd buy it. that is the reason why i never sold any of my lenses or cameras because they are great and i love to use them.

when i retired, i purchased my canon 300mm f2.8 II/600mm f4.0 II as my retirement gift to myself and i love using them, they are great pieces of engineering. but my most used lenses are my canon 100400 mk2 and 24-70 f2.8 II. my other primes and teles are basically collecting dust on the shelf.

if and when i move to R format cameras, these "L" lenses are staying with me since the are all compatible with R cameras. this way i'll have the best of both world

the best.
