I have the Nikon 1.4 versions i and iiie. The metal on the flange is designed such that one fits and the other does not. I honestly forget which is which and can check for you if important... Pm me. But the answer that nikon 1.4 does not fit is wrong. Some do, some don't.

Often used with polarizer for foliage/water. It's less than an ounce.

200-500 3 ED elements
80-400 4 ED elements - 1 Super ED element

ED Glass is an optical glass developed by Nikon that is used with normal optical glass in telephoto lenses to obtain optimum correction of chromatic aberrations. Super ED glass exhibits an even lower refractive index and lower light dispersion than ED glass, while excelling at eliminating secondary spectrum and correcting chromatic aberration.

Good glass costs money.

Hear Moose Peterson discuss the 80-400:

Finally, the 80-400 accepts a common 77mm filter. The 200-500 takes a 95mm filter.

Bill: so why do think Nikon sells the 80-400 for a 64% premium over the 200-500? 2399 vs. 1399. Because they don't know what they are doing?

Our family has the 80-400, Tamron 150-600 G2 and Sigma 150-600 sport. The 80-400 is as sharp as the others and has two advantages. 1) Often a better range 2) Much easier to handhold. My daughter used the 80-400 in the shot she won the Nat Geo Student Photo Contest... So the Nat Geo judges found it sharp too!

I have only the Nikon 1.4(versions 1 and 3 - they will fit different lenses) and an older Kenko 1.4 plus the Nikon 2x.

I played with them quite a bit on both lenses and ultimately concluded that with the resolution on the D810 and D850 I was equal to or better off to crop into the image than to use TC.

There are caveats...I feel that in some small instances the TC is worthwhile. Example: Shooting jumping leopard rays from my condo balcony in Cabo while drinking coffee at sunrise, the TC was good because quite simply they were dots otherwise at a mile offshore and did not record a big enough image on the sensor to crop much. So what does that really mean in practice? Those shots are good enough for me to enjoy and I can even see the tails at a mile...but they are not really good enough to print bigger than 5x7 or maybe 8x10. So the reality is even though I have all the TC's (and they work great on a modern Nikon 70-200 2.8 with almost no discernible IQ loss) I seldom ever use them on either of these 150-600's.

By the way, in broad daylight conditions they AF on both lenses - not quite as snappy, but OK. You just lose the ability to use peripheral focus points on the sensor array and have to use the cross sensors.

Again - I don't have the brand matching TC's which is specifically what you asked, but I thought I would share this info.

I have both the Tamron 150-600 G2 and the Sigma 150-600 Sport for a D850/D810/D500. Bottom line: Very similar image quality with maybe a 1% advantage to the Sigma. But, the Tamron is the one in the bag. The weight difference is just enough to mean handhold vs. not. Tamron is significantly smaller, has an actual front lens cap (quicker on and off) and the zoom ring turns in the right direction for a Nikon user.

When we go to places like Alaska/Galapagos, I bring both and I use the Sigma while my wife uses the Tamron.

FWIW, my daughter (18 yrs old) much prefers the Nikon 80-400 for the greater low end flexibility/size/weight and maybe we got a "good" copy, but damn it's sharp! In fact, she took the photo she won the Nat Geo Student Photo Contest with using that lens on a D800.

I was trying to place the wooden bridge over the creek and can only think of the one near the general store at Virginia Lakes

What lakes are pictured? We have a home in June Lake, so curious.

Amen! I had given that feedback to Ikea and Aaron Bros. The precut mat and frames should be set for digital sizes noting that for many people 13x19 is the biggest they can print... Where are the precut mats with 13x19 inside dimensions? Yes I know that ff is 13x19.5. I am blessed to have larger printers but for many years that was all I had and even one more inch than 12x18 makes a big visual difference. Likewise where is the precut 17x25.5 and matching frame. Why all the oddball frame sizes at Ikea?

Since the sender asked about this lens specifically I want him to understand that it does work in reality not hypothetically as to some other lens. It didn't seem clear from your post that you were speaking of other unspecified lenses, not the one he was asking about for which this system is an elegant solution to his needs.

There is ZERO vignetting using the fotodiox system on the 14-24. The affixed mount is wide enough to hold the filter in front of the front element without touching it even though it is bulbous.

I use the fotodiox product... Works perfectly for far less than a different lens while still allowing 14mm wide angle. I leave the adapter on at all times and just add the cpl as needed... Like any other lens.

Over $9000...not an issue I am worried about!

That precisely sums it up.

We have three shooters in the family using D500/D810/D850. I will say that the D500 shooter is slightly jealous of the detail obtained on the D850 in comparison and will likely be trading up.
