Let us see:
Canon road map to add to the hundreds of their lenses with a huge number that Sony does Not have anything like them. Besides the current lenses Canon has that Sony cannot come close to matching here are the 2021 lenses being released in 2021.
TS-R 14mm f4L, TS-R 24mm f3.5L (Sonny still does not have the technology to make a simple TS lens yet.), RF 10-24mm f4l, RF 14-35mm f4L, RF 24mm f1.8 Macro, RF 35mm f1.2L, RF 100mm f2.8L Macro, RF 135mm f1.4L, RF 100-400mm f5.6-7.1,
RF 400mm f2.8L, RF 500mm f4L, RF 600mm f4L, RF 800mm f5.6L and the RF 1,200mm f8L.
Then the super affordable, compact, light and great hiking lenses already available the 600mm and 800mm lenses just made available.
Sony is so far behind in choices as to be laughable.

So far behind. Hmm that's why it is the sales leader. At least you came up with some data this time.

Alright, let's get specific...

Sony themselves currently offers 51 e-mount lenses... 32 full frame, 19 APS-C crop. That doesn't quite add up to "hundreds".

If you add in third party manufactured lenses, there are 126 e-mount autofocus lenses in total. There are another 130 or so manual focus third party lenses in e-mount.

It is true that Sony has the most lenses for mirrorless cameras, as of today. They introduced their first e-mount cameras and lenses in mid-2010, so have had ten years to develop their system.

Fujifilm offers around 30 X-mount mirrorless lenses (not counting color variants... some models are offered in choice of silver or black finish). All X-mount cameras and lenses are APS-C format. (Fuji also makes medium format digital G-mount cameras and lenses.) There are another 15 or so autofocus third party lenses made for X-mount, as well as nearly 90 manual focus lenses for the mount.

Panasonic and Olympus offer around 36 and 30 lenses respectively, interchangeable for use on their M4/3 mount cameras. There are a small number of third party autofocus lenses being offered for use on M4/3, and quite a few manual focus only. (Panasonic also is now making full frame, too, with only 13 lenses so far, but because they're participating in the Leica L-mount alliance there are a number of additional lenses usable on their FF cameras.)

Canon and Nikon are only just getting started with their respective R-series and Z-series cameras and lenses. These two systems are just turning 2 years old. They are "toddlers" in the full frame mirrorless market (Canon is more experienced in APS-C, while Nikon's weird 1"/CX mirrorless went down in flames a few years ago.) So far Nikon has 16 lenses and Canon offers 15. Both are expecting to greatly increase their lens selection over the next 2 or 3 years. So far there are only a few autofocus third party lenses made for either system, as well as some 25 or 30 third party manual focus lenses.

But, again, for both Nikon and Canon this is only two years in, compared to ten years that Sony has been at it. Step back and look Canon's and Nikon's more well established SLR system.... where there are roughly 300 lenses available for each of them, including around 90 from Canon and 125 from Nikon themselves. This gives us some idea where they each plan to go with their mirrorless R-series and Z-series systems.

If I were Sony upper management, I'd be a bit nervous. They've got Nikon and Canon coming hard after the full frame mirrorless market share Sony has enjoyed pretty much exclusively for around seven years. (Not counting Leica.... Or Panasonic, who are only about a year into their full frame mirrorless.)

I can shoot any SLR lens ever made on my Sony, so I have every choice in the world. So lens choice is not an issue, it comes down to electronics, something that Sony is the world leader in.

You can now do the same with SLR lenses on all mirrorless bodies, so there's nothing unique there. But, professional ergonomics, including menus and physical handling, as well as customer support are where the leader distinguishes their leading system from those with just really good gear.

The above post did not the Minolta and Sony A mount lenses. 35 years of excellent glass that functions fine on E mount cameras with Sony adapters. The new adapter coming out later in October extends the new technology such as eye focus, animal focus and many others to the A mount.

In the end if the image doesn't cut it all else is irrelevant.

Every successful photographer is driven by an inner voice telling them Canon is the better camera.

Architect1776 Loc: In my mind

You need to remember ALL Canon EF series lenses are 100% compatible with the RF mount so they can be counted. Unlike Sony. And as far as RF lenses there are not as many but I can fully use ALL my EF lenses and not know any difference. Advantage Canon.

When it comes to big companies Sony is not in the same class as Sansum everything from oil tankers through to washing machines, the world's largest container ships to mobile phones. Military equipment to DVD players that is a large company

Gee for me it was Leica that I lusted for and Contax (after picking one up and shooting with it, I've never held a camera since that felt as nice in the hand) I wish I had gotten instead of the Canon equipment I had, which was reinforced when, several years later, they totally obsoleted my lenses (breach-lock FD) when they came out with auto focus. At that point I thought, wish I had gone with the Nikon, I could of still been using my lenses all these years. Had to wait till Sony came out with mirrorless to use them only to see how inferior they are to the new Sony lenses.

CHG_CANON Loc: the Windy City

So, you would have preferred that Canon lumber along like now 3rd place Nikon, rather than move the entire imaging platform boldly into an all electronic system based on EOS and then the industry leadership they maintain through today?

The market and the industry has confirmed Canon chose the better of the two directions.

Architect1776 Loc: In my mind

PS, all your FD lenses now work on the RF cameras and a huge portion of Nikon lenses now do not function on the Z cameras including their AF lenses.
ALL Canon AF lenses work 100% perfectly with the new RF cameras.
Should have stayed with the innovative leader, Canon.

If you want to be a better photographer, buy Canon equipment.
