Okay, I give up. You say yourself that you own AF-D lenses, but they work fine with your D800 and D7100. OF COURSE THEY DO! AF-D lenses are fully compatible with both cameras. Try to autofocus one of your AF-D lenses on a D40 -- which was all I ever tried to say -- and let me know how it works for you. This site is clearly the "cult of MT Shooter", and no one is really smart enough to pay attention to what is being said. I have better things to do with my time. I'm going to stick to Nikonians and NikonCafe in the future, where real photographers seem to have no problem understanding basic concepts.

No, they aren't D-mount, they are D-type. All Nikon SLR lenses are F-mount, throughout all the various iterations. I thought that was made clear early on . . . The same link you provided clearly references "AF-D" lenses, which is what we are both talking about. The link you are referring to also clearly indicated that the Df camera is unique in that it can use all the different types of lenses, which is NOT true for every other Nikon camera. The page you provided makes that clear -- perhaps you need to pay more attention to details, which is what this whole foolish discussion is about.

The only point I've been trying to make is that the D-type lenses will not auto focus on all Nikon cameras, because they lack an internal focusing motor and rely on a screw drive in the camera body. If the camera body doesn't have that, and the ones I've mentioned previously don't, then those lenses won't be able to auto focus with those bodies. I challenge anyone to find any authority that says otherwise. In fact, here is Nikon's own chart from the same site you provided that says the same thing:

https://www.nikonusa.com/Images/Learn-Explore/Photography-Techniques/2011/Which-Nikkor-is-Right-for-You/Media/NIKKOR-lens-compatibility-chart.pdf

The AF lenses listed are the same ones I'm talking about. The chart lists those camera models which have "Limited Compatibility† Can only be used as a manual focus lens. No AF."

As for my credentials and why I don't believe MT Shooter (and it's only in regard to this one simple issue) -- because I've personally owned the exact cameras and lenses that I'm talking about, as a working pro for the last 15 years. I don't claim to be an expert from reading Rockwell's site (in fact, I have't looked at his site for years before today) and I also provided three other more authoritative sources; did you bother to read those? Otherwise, it seems you are quick to criticize someone who has the facts (but who you don't know) simply in favor of someone you feel you do know, but who doesn't have the correct facts.

I know they both exist, but they are different lenses. That was my point.

You are an idiot. I'm not a KR pundit, but sometimes even his simplistic site provides good information. If you don't like his site, try:

From that site:

"E: Electronic Diaphragm
The new electronic diaphragm "E" lenses only work on Nikons introduced since about 2007. They work perfectly on all FX cameras.

YES: As of January 2018, electronic diaphragm "E" lenses work only on the D5, D4, D4s, D3, D3s, D3P, D3x, Df, D850, D810, D800/e, D750, D700, D610, D600, D500, D300, D300s, D7000, D7100, D7200, D7500, D5600, D5500, D5300, D5200, D5100, D5000, D3400, D3300, D3200, D3100, Nikon 1 J1, J2, J3, J4 with FT-1, Nikon 1 V1, V2, V3 with FT-1, and Nikon 1 S1, S2 with FT-1.

NO: These new "E" diaphragm lenses will not work on the D1 or D2 series, D100, D200, D90, D80, D70 series, D60, D50, D40 series, or the D3000, and will not work on any 35mm camera. The diaphragm will stay wide-open, which may or may not be a problem for you. In the case of tele lenses like the 200-500mm f/5.6E, this isn't much of a problem because we usually shoot long lenses wide-open, in which case the E lenses are compatible with everything. If you don't mind shooting wide-open; even on a 1959 Nikon F you can focus manually and shoot wide open except if it's an AF-P lens."

Moreover, I have not only researched this, I actually OWN the two Nikkor lenses I've described, along with more than a dozen more, and have owned and used other lenses -- including D-series lenses -- in the past. I have also owned the Nikon D40x camera (and a D70, D80, D2H, D2Hs, D300, D3, D3s, D700, D4, D4s, D5 and D850 -- and I still have the last five cameras) and know these two lenses wouldn't work with the D40 from first hand experience. I've been a professional photographer for more than 15 years, not just a fan boy whose mouth exceeds his knowledge. Most people come here looking for information, but you just want to have an argument. Hopefully others will be able to pick up good information from the resources I've listed, and ignore an abusive troll like you. As far as this topic is concerned, I'm done.

This was almost embarrassing. A couple of weeks ago, I asked for your opinions on Portrait Professional. I was taking head shots of a group of actors at a local playhouse. They will be displayed in the lobby while the play is being put on. After reading your comments and reviews, I bought and used the program. I was pleased with the results. When I brought the prints to the theater, they went wild! If some of you people examined them, I'm sure you'd be able to point out flaws, but for people who live with quick cell phone shots, these look very good. Several people took pictures of the pictures with their cell phones. Now I have to print copies for everyone to take home.

They assumed that I was a professional and wanted my business card so they could come to my "studio" and get more shots. With a straight face, I told one woman that I'm not a professional, but I have a good camera and tripod. I still laugh when I think of this situation. Come to think of it, it was probably partly a case of mass hysteria. When the director saw the pictures, she started screaming about how good they were, and I think that attitude became contagious. Of course, I'm not saying this to brag because it was LR and Portrait Pro that made them look good.

What's ironic is that these people love the pictures that don't look the way they do themselves.

I did have a problem with printing, and I'll make that a separate post.

I know this is an old topic; but maybe I can some. I am heading to antelope canyon on a photo tour in about a month and want to make sure I get good shots. I am assuming that the raw photos will improve my chances of fixing improper exposures.

This discussion is directed to those who use raw. I have read many of the on-line explanations about raw photos having more color depth, levels of brightness and the file not degrading when it is edited. I notice for my d500 that for the same photo the jpeg is 13.9 mp (5568x3712x24b) and the raw 25.7 mb (5568x3712x48b) there does not appear to be much if any difference between the jpeg and the raw . On the screen of the 4 year old 23" PA248 ASUS the images look the same and the same for the Dell ultra sharp. Resolution is set at 1920 x 1200 for both. The color space is Adobe RGB. The shots were at iso 200, f/10, 1/100s and 18mm with auto white balance facing north on a sunny morning. The shot goes from light shade to bright sun on the trees. I shoot both raw, compressed, 14 bit and jpeg large fine.
Maybe I am missing something; but I think most of the good shots do not need postprocessing. If the shot is important I bracket expose and may change the f-stop and shutter speed.
It seems to me one shoots raw to fix shots that were incorrectly exposed.
I print my photos on an Epson Artisan 810. So far, I have not tried any shop for a larger print. The local drugs stores and other similar places do not good work.
Questions and comments
1. Should I switch to rRGB color space and why?
2. How can I tell how much brightness levels are in the photo? Is it in the histogram? The histogram for the two photos are not the same.
3. The apparent brightness in greater in the jpeg.
4. What changes do you make to most raw shots?
5. Are there good on lind articles on how to process raw photos?
6. What format do you save them in after post processing?

Thanks to all those help
