Sure! I should have put the two thoughts together better: I'm looking at attribution; so only Wikipedia and the photographer claim 'origination' such that attribution is legally required.
I realize...

Being 'official' would be my only concern- ensuring that the photographs are used for Wikipedia only and properly attributed etc.

And while I can think of some concerns that professionals might...

The 40/1.4 | Art is purportedly a very sharp, very well rendering lens- one would expect it to largely outperform the 50/1.8 S in every metric except perhaps outright sharpness, where they might be...

While it's certainly possible to shoot the FE 1.8/55 and miss the CA, it has enough to make an old Canon EF 50/1.4 downright blush.

I'd say upward of 90% of the shots I've seen from the lens at...

Makes sense if you've already invested in the system- but lenses sell the system, and not seeing a tremendous difference between shots with this new Fuji 250/4 and a 70-200/2.8 at f2.8, let alone a...

I'm with you there, Jeff!

I've actually done that; backups of backups, so to speak, and as I'm homelabbing a bit, I've set up a 10Gbit link between my desktop and my NAS system (custom, running...

If I could set up a system at home (or anywhere!) with a 'Lightroom CC Server' that I could access from anywhere, I'd be interested in using it, but it still needs feature parity- or at least...

f/2, mirrorless, with OS and APO (think Otus) grade correction on top of linear motors for snappy stills and smooth video, and perhaps most important, smooth rendering!

If the Tamron lenses have problems, then they were improperly programmed from the factory. The Z mount is the F mount, but shorter.
Modern USD Tamron lenses should perform very well with the FTZ...

RF and Z are electrically the same as EF and F, respectively.

The only adaptation is mechanical, and adapted Sigma lenses on these mounts are electrically native and perform as such.

This was...

Illia is right- it's just a tube.
Further, with respect to AF- thanks for the clarification- it seems SIgma's EF protocols don't adapt as easily, so it is possible that an adapted Sigma design with...

The people may be different but manufacturing is a matter of applying processes.
Humans, any humans, can do it.
That's not a political thing, it's a scientific thing, and espousing otherwise is...

...why are you comparing wide-angle DSLR lens design to a mirrorless lens design in size?
Hell, the Sigma has an empty tube at the end to make it 'native'!

Whether or not copy variation is an issue has nothing to do with the country in which it is made.
Sony either nailed the manufacturing process or they didn't.

Based on the RF and EF-M mount dimension differences, an adapter should be possible to put RF lenses on EF-M cameras.

Nah, that'd be Canons 16-35/2.8L III, but I'd also submit that there's room for both; each has their own advantages.

People buy APS-C cameras, but rarely upgrade the lenses. Many never see the kit lens detached.
Remember that companies build the products that people buy...

You have the FTZ adapter...?

Link works, very nice shot!
@Decooler: lenses are difficult to build- as always, if you get a copy that does not work with your camera, it's always good practice to try another. This Tamron is...

Anyone get a read on filter size?
