I can highly recommend the Voigtlander Ultron 40mm F/2 pancake lens.
I have had the Nikon mount version for quite a few years and in my opinion it is an excellent performing optic, excellent in my nature/landscape work,....very comfortable and easy to work with.
I use it often with the camera's on board pop up flash because of its easy quick focusing when shooting people type occasions.
Its short length profile makes it ideal for comfortable carrying as a walk around lens as well.
It is a mechanical operation only lens built very solid,...not an auto focus,....great for my work since I only shoot manual mode using a Nikon D810 or D800E.
Hope my experiences are of interest and useful in your search.

The images are outstandingly sharp as well,....IMHO.

Only your dog can see the difference,..................lol

Looks more like an activation device for something more sinister!!!

Thanks muchly for that link to see those enviable natural world images that any one of us would have been more than proud to have taken.
A lot of talent on display to inspire us all.

When cell phones first came out,..(flip phones t hen),....I said to myself,...those will never catch on and be popular!!!!,.................so much for my hypothosis!!!!

I'm currently running Windows 10 PRO on a brand new build I just completed Jerry,....Microsoft shows you how to create a free bootable USB thumb drive installation operating version for evaluation purposes indefinitely,...on any computer,...............later you can activate it (by purchasing a legit copy of Win 10 and entering its legit activation KEY #,......do it before Jan 2025),....and you can skip Windows 11 and get for free > whatever Microsoft version comes out next,....Ver 12 or whatever Microsoft calls it?????,......or just continue running the fully operational Windows 10 evaluation mode for as long as you like.

As long as you do not mind an occasional "nag" message on your desktop,....for you to to activate it.

That's what I'm doing for now till I see what Microsoft has in mind before purchasing my legit version w/ key #.

I can reinstall my evaluation Win 10,....umpteen times at (no co$t,....right off the USB drive) while experimenting with any of features I like while deleting features I'm not interested in,......this way I'm trying while enjoying different innerational alternative schemes of "leaning out" my Windows 10 final size on my operating system C: drive.
Another thing I am not "branding" my new motherboard bios with any imbedded identity of any kind till I am ready to do so.
Here's the link to create your own USB bootable Windows 10 installation onto any computer free and legal thru Microsoft indefinitely.............https://www.microsoft.com/en-us/software-download/windows10

Ps,......Microsoft also does this with Windows 11 version as well

A very nice alternative to committing any $$ at this time too.

Just my two cents.

A general guideline, rather than a strict rule; an approximate measure or means of reckoning based on experience or common knowledge.

To put it simply,.......the "Rule of Thumb",.....thru the viewfinder of the camera.

I use split foam pipe tubing secured with duct tape,,....readily sold cheaply at any hardware store,.....but then there are also nice form fitted quilted ones with soft cu$hy padding for the more discriminating buyers.
It's going to take a beating during usage anyway,....shop accordingly.

A woman once held a door open for me,....I commented,..ohhh reverse chivalry,....thank you,....we both laughed.

In a sense, we photographers are sometimes unknowingly historians capturing the last fleeting images of subjects now or soon to be lost to obscurity.
