My advice to you will be to gather some statistics of the zoom range you use with your 18-200 now and from there figure out which lens to go with. When I had D810 I was mostly using 24-120 F/4 when traveling, but I was missing the 2.8 aperture. After one of there travels in Europe, the FL statistics showed that less than 7% of the shots were made with FL over 70mm. As a result, my traveling lens now is 24-70 F/2.8.

I'm curious as to what lens most people use on their D 810's. I may be only dreaming but I'm going to run it by my chief financial officer about upgrading from my D7200 and I'm looking at the D810. I see it most often paired with the 24-120. That seems short as I use the 18-200 on my D 7200. Any opinions would be appreciated.

Bob,
As you correctly noted, diffraction occurs even when light wave passes around a corner. Since "corner" can be considered a slit with infinitely large dimensions, there is a disagreement between the first and the second part of your sentence. If we will talk physics, the diffraction equations that describe the effect become unsolvable when the dimensions of the diffracting object become smaller than the wavelength, when other effects take place.
[quote=rmalarz]Well, actually it is, or is it?
Diffraction of light occurs when a light wave passes by a corner or through an opening or slit that is physically the approximate size of, or even smaller than that light's wavelength.

I would use a CP filter to suppress the distracting reflections.

The reflections from the water are too harsh and distracting. A polarizing filter may have helped here.

Yes, it compresses and depending on your setting it may backup only the sectors that are being used.

I don't see a real difference: Before being developed any photo emulsion medium, film included, contains only a latent image. The difference is that the film is being developed only once, while a file containing latent image can be "developed" infinite number of times using infinite variations of the development process. Immediately after the shot though, both media contain only latent images.

I subscribe to the magazine "Arizona Highways" and the yearly photo contest winners have been published. This is open to both amateurs and professionals. This years grand prize winner shot was taken with a Fugifilm X-T2. This is to show that the most expensive DSLR's no longer rule the domain.
Another example of wrong Cause and Effect Relationship conclusion. So common nowadays!

I've got two monitors. One is a year old 24" LG Ultra Wide, the other is an older model and regular shape 19" Samsung. Both are self calibrated by me using a blank sheet of print paper from my regular printer service.
The older model Samsung monitor was needing calibration so often that I, (hey, it's about 15 years old!), only use it sparingly. One of these days I'll get another newer monitor to match the LG. (Love it)

I am also curious about how this works. Please elaborate.

LR works great with 6-8 core with multi-threading. The current i7 8th gen is an ideal platform for LR, and a XEON is even better - much better. Photoshop doesn't use the extra cores beyond the basic quad core.
As far as utilizing the cores you seems to be right - on my 8 physical cores machine a simple burning action with the brush registered increased activity of all cores. Did the test on a 24Mp image from a6000. There was still a perceptual delay in displaying the effect, although I have a professional graphics with 8Gb video memory and HW acceleration, 32GB main memory and with LR I use a dedicated scratch SSD on which also the LR catalog resides. For me, on a higher pixel-size file from D810 (even more from D850), this delay was intolerable, so I gave up and move to another application.
Granted, my LR is standalone 6.14 and the new subscription version may have been improved.

What’s your favorite free standing monitor? What size? Do you calibrate the colors?
Currently I am with NEC PA272W (there should be a newer model). It supports HD calibration with i1Display Pro sensor.

Anyone besides me have a frustrating time with the sluggish performance of LR Classic tools? Brush, spot adjustment are disappointing, frustrating and slow with unwanted artifacts appearing as well. I appeal to the experienced and kind hearted Hoogers for your suggestions on improving speed and performance. Adobe tech help is evasive and seemingly unwilling to help.
Most gratefully,
Roger

I was also frustrated and that was one of the reasons I abandoned it. It looks like LR Classic does not use multi-core CPUs to full capacity (old code maybe?). While I was using it though, I found that more memory and using dedicated solid state HD as a scratch improve the performance, particularly the later.

Using it all the time, for all types of photography. The only way to know if it is good for you is to try it.

I am all stressed out after learning of the situation with Canon 5D Mark IV and raw files. I was shooting along just fine til I recently bought in to the idea that RAW is the only way to shoot if you are a "serious". Well I am thinking now that maybe it's a bit of hype and that most folks could not tell a raw processed shot from jpeg. I would welcome some discussion on this. Thanks
This has been discussed countless times, just do a search. Apart from that, please define "serious"

I think you will find that 1/2.3″ means (1 divided by 2.3)” or 0.434″ = 11mm and that is the diagonal measure of the sensor.
It is actually much smaller than 11mm. According to Wikipedia the inch notation of sensor sizes came to life long ago when they started replacing the camera tubes. At that time, 1" camera tube had a sensitive area of about 16mm diagonal, so sensors with 16mm diagonal were called 1" sensors. According to this notation, 1/2.3" sensor will have (depending on the manufacturer) something like 7.7mm diagonal. Full table of sensor sizes: https://en.wikipedia.org/wiki/Image_sensor_format
