wow, lots of good feedback here folks, thanks! glad i posted before continuing further down the path of buying lenses that test best! while i first watched the "angry photographer" on youtube i found him annoying. but, like a good sitcom, he grew on me and see that he has a lot of solid advice.
i watched one of his recently where he talked about why people buy primes, mostly for "rendering". here's his chart which reflects why, although i always wanting a normal zoom, i sold it less than two years later for the 50 1.4. that was before i realized that my old 60 was what i should have used! in other words, zooms had improved sooo much that i mistakenly assumed primes had too.
LAW OF IMPORTANT LENS ATTRIBUTES
as i master nikon's nx-d and plan to learn lightroom later this year, i realize that slight losses of color can be easily restored. but obviously, it is better to have never have lost it.
i've done some further comparison testing and am amazed at how good my old 60mm 2.8 is. looking at my prints from scuba shots, i further appreciate the excellent color i have in those pictures! it is lighter, less obvious for candids and less worry about damage. used ones at bhphoto are $260.
so for an 85, i now plan to get a nikkor D series 1.4. i don't regret selling my 1.8, as i knew it was not as good when i bought it in the mid 1990's, but budget restraint at the time... and, seriously, you don't really want super sharpness in a portrait. i remember that some people said, with good reason, that my 60mm 2.8 was too sharp for portraits. the old D series has almost half as many elements as the current sigma or nikon 85. 86mm filter size!, really tough to sneak up on someone with that.
there are plenty for sale on ebay, and i'm not in a hurry to buy. meanwhile, i plan to do some more comparison testing of the 60D, 50 ART, 105 micro and the 70-200. casual testing today shows me that they are all excellent. agree/disagree?
Should i post the comparisons in this forum?
I kicked off this thread because i sold my 300 f4 ED lens to get the 150-600 sport for motorcycle races. the old boy focused too slowly. looking back at the shots from it made me appreciate its superior color. i agree that the almost doubling of the elements to improve sharpness has reduced "rendering". glad i sorted this out before buying an expensive long prime lens!
i shot some ducks this week. it was dark and because it was raining, i did not want to spend too much time getting better shots and still learning this lens. should have stopped it down for more DOF for some of these. point is that i cannot complain about the color from the sigma sport (be sure to click to zoom):
