AF-S NIKKOR 70-200mm f/4G ED VR
I like everything about this lens, with one question. I think I understand that the f/4 on the lens means it holds f4 throughout the entire zoom length. Am I also correct that the lens is still capable of using the full range of f/stops on my camera, a Nikon D850?
Actually the range of f/stops are on the lens, not on the camera.
That f stop is the largest opening the lens has. I is the opening that you are looking thru when see thru the camera. when you squeeze the shutter it will close to what ever f stop the picture is set for. hope that helps
Check the EXIF data at different focal lengths to confirm.

Yes, the designated aperture on a lens like that indicates it's MAXIMUM or largest available f-stop. You'll have a full range of smaller f-stops to use with it... on a 70-200 it will probably stop down as small as f/22 or f/32 (though you should read up on "diffraction" before using the very smallest apertures). Most modern cameras give you choice of setting aperture in full stop, half-stop or one-third-stop increments.
There are a few exceptions... Some rather specialized types of lenses that don't have variable apertures. For example, most "mirror" lenses (catadioptric) have a fixed aperture. The light passing through those lenses is usually controlled with neutral density filters.

While the aperture diaphragm itself is in the lens, many modern lenses are controlled electronically by settings ON THE CAMERA. A Nikon "G" lens, in particular, will have no mechanical aperture controlling ring on the lens itself... doesn't even have an aperture scale, the way older lenses did. It's aperture can ONLY be adjusted via a dial or control on the camera body. Most modern lenses use this design now, so it's sort of natural that people would refer to "setting the f-stop aperture on their camera"... although TECHNICALLY they're adjusting an opening within the lens.

Not really.
Yes, really. That's exactly what happens.
LOL Jim this time you are right. Poor guy I think he must have said to the Sales person " I only want to spend $500 and the Sales person heard $5,000 as they do, so he walked out with a D850. Hope he read the receipt..maybe its not too late!

Thanks all for the input. I got a good laugh out of the last response because I developed a serious case of GAS. After studying more and reading more I decided to go all in. Yep, a Canon D850. Hard to find by the way. They are selling like hotcakes. In fact, if you look on eBay or Amazon you'll find that people are reselling them for $1000-$2000 above the usual $3296 price. All the usual sources are showing OUT OF STOCK. I think I found one on eBay. With luck, it will be here Tuesday.
For the second lens I bought the AF-S 24-70mm f/2.8 ED VR. I think I'll be happy with the FF camera. Watch for some new pics in the near future! Thanks, as always, for all the help!
Hi Dick,
A Canon D850 ..yeah that's the one. eBay one sounds just right. 24-70 nice, should fit the Canon real good. Dick you really do like jumping in the deep end hope you have your life jacket handy!. I'm thinking did your Mrs say ..get out of the bloody house and find a hobby..? Its Ok Dick I'm 60 I know how it can go down, but its a bit like you were thinking to go rabbit shooting and you have bought a tank !!!
Hey Jim I think this guy really really needs your help you should put him on your Buddy List.
Happy Days Guys, all good fun.
No matter what aperture you select to shoot at, it will always focus at the widest aperture available, in this case, f4.

I am sure there are many Nikon users that will take that "terrible lense" off your hands for "free".
It's is exactly what you think it is. Constant aperture throughout the full 70-200mm range no matter what the aperture is.

HaHa... I just sold my 47' yacht and I'm 72, so yeah, had to come up with something to do
I've always loved photography, so I'm just stepping it up from my "bridge" camera to a more professional grade. I'm excited. BTW....just canceled the Best Buy offer cuz 42nd Street Camera has it in stock and I don't have to pay sales tax! That's a big savings!
Cheers,
Dick
Well seriously that's great Dick, I would love a D850 myself so good luck with that... I'm sure you will get plenty of help on UHH. I can tell your not a man to 'do things by halves', must have had some good party's on the yacht.
All the best and I look forward to seeing some of your pics from the D850.
