I would like to use my Nikon D850 as the video source for Zoom. To do so, I will be connecting the HDMI output of the 850 to one of the USB-C ports on my iMac (my iMac doesn’t have a HDMI port). I have a HDMI to USB-C adapter, and a mini-HDMI to HDMI-A adapter. The D850 will be set to Video and Live View. Will this set-up work? Will my iMac screen display the video feedback of the D850? Also, could I run the video feed constantly for more than 30 minutes? I know that during video recording, the maximum recording time is limited to 29 minutes. I was told it is a technical limitation of the image sensor, preventing overheating.
Thanks,
Andre

Before buying a Nikon F-mount 1.4x teleconverter, check if it is compatible with your Tamron lens. I was thinking buying the Nikon AF-S Teleconverter TC-14E III but found out it was not compatible with many of my others Nikon lenses like the AF-S 24-70mm f/2.8E ED VR, AF-S 105mm f/1.4E ED. I could only use it with my 70-200mm f/2.8 and 200-500mm f/5.6. The issue has to do with the clearance or lack of it between the front element of the teleconverter and the rear element of the lens.

I did a search for timing belts for a Subaru and the recommended replacement interval is every 105,000 miles. Timing belts do not need to be adjusted between replacement intervals.
I had a 1981 4WD Subaru hatchback, manual transmission and put more than 325,000 miles on it. I don’t know how many more miles I drove it because the odometer failed, and I kept driving the car for another two years. This was one of the best cars I had ever owned, very reliable.

Thanks John. For this part I had to use Google translate:

"I can not speak German but I understood everything you spoke."

Then there is the movement by people want to "simplify" and go "full phonetic" with the English language (and others) in spelling and grammar while making their new system standard all over the world. They go so far as to get rid of several letters of the alphabet and many words.[/quote]

Let's simplify the english language as proposed below:

The European Commission has just announced an agreement whereby English will be the official language of the European Union rather than German, which was the other possibility.

As part of the negotiations, the British Government conceded that English spelling had some room for improvement and has accepted a 5- year phase-in plan that would become known as "Euro-English".

In the first year, "s" will replace the soft "c". Sertainly, this will make the sivil servants jump with joy. The hard "c" will be dropped in favour of "k". This should klear up konfusion, and keyboards kan have one less letter.

There will be growing publik enthusiasm in the sekond year when the troublesome "ph" will be replaced with "f". This will make words like fotograf 20% shorter.

In the 3rd year, publik akseptanse of the new spelling kan be expekted to reach the stage where more komplikated changes are possible.

Governments will enkourage the removal of double letters which have always ben a deterent to akurate speling.

Also, al wil agre that the horibl mes of the silent "e" in the languag is disgrasful and it should go away.

By the 4th yer peopl wil be reseptiv to steps such as replasing "th" with "z" and "w" with "v".

During ze fifz yer, ze unesesary "o" kan be dropd from vords kontaining "ou" and after ziz fifz yer, ve vil hav a reil sensi bl riten styl.

Zer vil be no mor trubl or difikultis and evrivun vil find it ezi TU understand ech oza. Ze drem of a united urop vil finali kum tru.

Und efter ze fifz yer, ve vil al be speking German like zey vunted in ze forst plas.

Thank you for your very detailed answer to my question. Your Micro/Macro rig is very clever, and so is your lightening technique. For sure many of your insects’ pictures are the best I have ever seen in any publications. Macro-photography let us peek in a world that we are not accustomed to see. We mostly despise insects and don’t hesitate to trample on them or spray them with insecticides without thinking about the sophistication those life organisms are made of. Nature is amazing with its diversity, from a minuscule ant to a giant blue whale and everything in between.

Herman,
I checked your portfolio on Flickr. Amazing pictures! I have a question if you don’t mind. Are you using a distance interval (like 1mm or less) to move your subject closer to the lens, or do you just move the stage to the next in-focus area of the subject by looking in the viewfinder? I can only guess by looking at your lens setup, the DOF should be razor thin. Thx
Andre

[quote=twice_shooter]I’m a bit confused as to why there are recommendations here for the OP to purchase a Nikon D6.

Twice_shooter. I’m the one that recommended to the OP to get a Nikon “soon-to-be-released” D6. The OP wants to upgrade his present Nikon D7200 system and may be willing to wait for an exceptional camera like the D6. This camera will be an upgraded D5, which is a darn good professional camera, and knowing Nikon it won’t disappoint the pro shooters. If you can afford a Pro model, why not buy one of the best and newest. Personally, I own a D850 with several excellent NIKKOR lenses, and am very happy with the results. When I bought my camera the D850 was as much as I could afford on my limited budget. However, I have no doubts some of the UHH members have the means to buy Pro equipment without breaking a sweat. My post was to convey my opinion to the OP and was not off base as you suggested.

[quote=DICK32]Hi aberthet: You flatter me with the big-time business photographer title.

Hello Dick. Before making this statement I looked at your linked Website and was impressed how well it is made. The pictures are of good quality showing your professionalism.
Congratulations to your family for being in business since 1897.
While the new D6 would be my choice, many other cameras could do the job as well. You may want to look at mirrorless cameras from Sony which are impressive. From reviews I read, Sony auto-focus seems the best feature of the camera. I would select a Full Frame sensor camera (FX, 36x24mm). One way to make an intelligent decision is by renting and testing the equipment before buying it.

Having personally a D850 I would recommend it for the type of work you do. However, when I read your post, it seems you are a big-time business photographer travelling all over the world. For this type of business, I would not hesitate buying professional equipment. Since you like Nikon, the soon to be released Nikon D6 and several professional FX lenses is the way to go. I don’t need to remind you that all equipment you buy in the pursuit of your profession can be deducted from your business’s gross income or depreciated over time.

[quote=lsaguy]Dyximan, What you're seeing at the wingtips are the vortices caused by high pressure air on the bottom of the wing being pulled spanwise by the low pressure air on the top. That and a smoke system that allows you to see it.

Isaguy, your explanation is partially correct, but no smoke is needed for the vortices to become visible. What you see is water vapor. Depending on ambient atmospheric humidity as well as the geometry and wing loading of aircraft, water may condense or freeze in the core of the vortices, making the vortices visible.
BTW I like your avatar, having flown hang gliders for many years in my younger days.

Your question is very timely, yesterday I just modified my Manfrotto Head Ball to install an RRS Lever Release Quick-release adapter 80mm for ARCA plates.

You will need to order this adapter (B&H)

https://www.bhphotovideo.com/c/product/1062503-REG/desmond_dbad_female_to_male_boss.html/c/product/1062503-REG/DBAD_Female_to_Male_Boss_Adapter_for

However, I found a little problem that I will have to fix later. The adapter boss is a little bit too tall for the Manfrotto groove, therefore the adapter flange is not sitting properly against the bottom of the RRS Quick-Release. There is a 0.3mm gap. I will file the boss to remove this gap.

The carry-on restriction is because you selected a United's Basic Economy ticket. If you had bought an Economy ticket, which may have cost you an extra $60 or $80 (round-trip), you will have been able to take with you a carry-on to put in the overhead bin, and another smaller bag under the front seat. I don't think UA uses turboprop airplanes between LAS and SFO, but A320s or B737s. You got what you pay for!

I don’t have a crash story to tell, and I will never have one after reading all these mishaps. From now on my Nikon D850 and its expensive lenses will be grounded......well maybe :-)

Well I was able to get the following info:
