They aren't autofocus so Canon doesn't fear any loss of fullframe autofocus RF lens revenue . Lensbaby are specialty lenses that dont have a wide market that could threaten Canon, ever.

Sigma and Tamron sell more lenses than Sony, Nikon and Canon. So fullframe RF lenses from Sigma and Tamron would have an economic impact on Canon fullframe RF lens sales.

Canon is only allowing a manual-focus-only Laowa 10mm f2.8 rectilinear lens in RF fullframe mount. This Laowa 10mm f2.8 lens comes in autofocus fullframe versions for Nikon Z-mount, and Sony E-mount. I have the autofocus fullframe version for E-mount, just released in the past month.

Cheers

I always say use what works for you and be happy.

Maybe you might try out one of these excellent lenses.

One tip, the APS-C Sigma 16mm f1.4 DC DN and Sigma 56mm f1.4 DC DN in E-mount have tested out with equal sharpness of the best top-rated Sony lenses. I had that Sigma 16mm f1.4 DC DN lens for my Sony APS-C A6500 and it was unsurpassed.

I look forward to the inevitable independent comparison tests coming, pitting these third-party APS-C RF lenses against the best Canon APS-C RF lenses.

Cheers and best to you.

So far,

From Sigma, APS-C RF lenses:

18-50mm F2.8 DC DN
10-18mm F2.8 DC DN
16mm F1.4 DC DN
23mm F1.4 DC DN
30mm F1.4 DC DN
56mm F1.4 DC DN

From Tamron, APS-C RF Lens:

11-20mm F2.8 Di III ARXD

Sadly, Canon's cripple hammer strikes again, as fullframe R users are still denied access and use of nearly all of the over 150+ (and growing) excellent and affordable Third-Party fullframe lenses available to other brands of cameras.

There is a Laowa fullframe, manual-focus-only 10mm f2.8 rectilinear RF lens allowed by Canon, cost $799 USD.

Nikon Z-mount and Sony E-mount users get the autofocus versions of this Laowa 10mm f2.8 rectilinear lens. I personally spoke with Laowa's USA Rep. ,and he told me Canon wont allow the AF version in RF mount. I have this superb lens in autofocus E-mount for my Sony A1, A9III, A7RV, cost $799 USD.

And there is one manual-focus-only Viltrox RF lens allowed by Canon . I personally have the superb Viltrox Autofocus 16mm f1.8 lens in E-mount, a GM-quality lens, for only $549 USD. Not allowed by Canon in RF mount.

While Canon sells its RF 15-35mm f2.8 RF lens for $2399 USD, on sale for $2100 USD right now at B&H. https://www.bhphotovideo.com/c/product/1502499-REG/canon_3682c002_rf_15_35mm_f_2_8l_is.html/?ap=y&ap=y&smpadsrd=&smp=y&lsft=BI%3A6879&gad_source=1&gclid=CjwKCAjwuJ2xBhA3EiwAMVjkVBEj-46PBxr6NrmPzzXiTtkmuLoHoKHmMIDiCNzUDs3yDUKhPT2lxhoC-oYQAvD_BwE

Cheers and best to all Canon R users, APS-C and fullframe.

Canon opens RF mount for some APS-C lenses from Tamron and Sigma, but does not allow any third-party fullframe RF lenses. Any Canon RF users interested in these APS-C lenses ?

The latest bodies doesn't mean the most expensive bodies by a long stretch. there are excellent quality bodies at different price levels that wont break the bank, and coupled with good long lenses and the appropriate TCs will yield excellent results. This is not only achievable with the most expensive bodies and even the most expensive lenses.

FYI, my Sony 200-600mm lens used in my example, is a performance bargain at $1898 USD new at B&H, and even less used. Nikon, Canon, OM System, Sigma, Tamron have similarly priced long lenses that will yield great results with the appropriate TCs. :

Quality 24mp bodies like the current Sony A7C, like the 24mp of my A9 used in my example, can be had for as little as $1598 USD new at B&H, or even less used:

Sony 1.4 TC and 2X TC can be had for $400-$500 USD each.

Just the facts.

Cheers and best to you.

The new reality is that the latest TCs, internally and external are excellent optical quality, and top wildlife and sports pro photographers around the world use them all the time, with excellent results.

Just go to any Wildlife and Sports shooters groups and forums and see wonderfully sharp and optically excellent shots made with the latest TCs. It is just fake news that TCs are no good nowadays. The latest TCs and best long lenses are designed to work great together, and they do if you know how and when to use them.

Here top wildlife pro Mark Smith uses both Sony 1.4X TC and Sony 2X TC with the latest Sony 300mm f2.8 GM lens:

At first it was just the Sandisk 4TB SSD, but there have also been unrecoverable data failures of other sizes of Sandisk SSD. Just stay away from their portable SSDs for now. Better to be safe than sorry.

Cheers and best to you.

You are welcome.

I had a selection of three stops of exposure within nine bracketed shots, for each time I shot. Then I could pick the best exposure in post. That really saved me from worrying. I used aperture-priority.

And our local atmospheric sky conditions of clouds, haze, whatever, were different at our different locations, and changing all the time, so no two exposures would be exactly the same from different locations.

Cheers and best to you.

This alert has been out for a while . Sandisk SSD's used to be the standard for many top pros and hobbyists. I have several of the smaller and older ones up to 2TB and they have been stellar in use for years, shooting and storing photos from my shoots around the world..

Sadly the 4TB Sandisk SSD ones are crap. Seems it is bad soldering on an internal circuit board and when that goes, all data is lost. Yes DO NOT buy any of the 4TB Sandisk SSD ones.

In fact stay away from any size new Sandisk SSDs until it is proven that they have their quality control back.

Like many pros and hobbyists I have moved to Samsung 4TB SSD ones which are getting rave reviews for reliability.

I bought two of the Samsung 4TB SSDs, and I successfully copied off all the data I had on my single Sandisk 4TB SSD and retired it before it failed on me.

If you ask Sandisk they will tell you to share your 4TB SSD's serial number with them, and they will tell you if you should be concerned, but dont trust that at all, just stay away.

I will continue to use my older 500GB, 1TB, and 2TB Sandisk SSD drives which have been bulletproof, but I wont be buying any new Sandisk SSDs of any size.

Cheers and best to you.
