Did Canon See the Writing on the Wall with the RF Mount?

Tired of Canon's RF closed mount policy last week I bought a SONY A1 II along with a 50-150mm f/2 and a Sigma 28-45mm f/1.8 Art.

I'm not switching systems, but I'm not going to renounce to unique lenses like the Sigma 15mm f/1.4 fisheye, Sigma 35mm f/1.2, Sigma 28-45 f/1.8, Sigma 135mm f/1.4, SONY 50-150mm f/2, Sigma 200mm f/2, Sigma 300-600mm f/4, etc., or cheap and nice chinese lenses like what Viltrox offers to play with.

For me, adding a SONY camera to my arsenal is adding a powerful toolkit to get the job done and differentiate myself from other photographers even more.

I don't believe in brand loyalty. Being married to a brand is so stupid.
I could not agree more..

Canon Focus Motor Technology Through the Ages

Hi everyone. I am sorry for being critical here, but as a Canon lens specialist I found this summary to be very poorly researched and partially incorrect. Here are just some examples:

1. DC micro motor and micro motor are exactly the same AF motor types, whereas in this summary they are listed as two different concepts (which they are not).

2. Coreless motors have not been used as autofocus motors in Canon lenses. In their Canon EF Works III document, there is one page where coreless DC motors are mentioned. However, after more than 10 years of repairing canon cameras and lenses, I can confirm that coreless DC motors are used by Canon inside of their DSLR bodies to springload the shutter and mirror units, but not inside lenses.

3. The original arc form drive was not a large brushed DC motor as stated above. In fact, the very first arc form drive motor was a stepper motor with a stator shaped in a thin arc to fit inside the lens barrel.

There is a surprisingly detailed and highly accurate source showing all of Canon's autofocus motors here:


Cheers!

Canon Officially Announces the Canon RF 45mm f/1.2 STM

I wish you to have a lot of fun with this lens. Don't mind the criticism about MTF charts etc. here, I am pretty sure that this lens allows for good images anyway, and its price is pretty decent.
Thanks, I do hope I this will enable me to carry my camera more often. I absolutely love the images from my RF 85 1.2 but it is certainly a beast to carry and I do end up being very intentional (think twice) when I do take it with me on trips. I am expecting the 45mm to be more of a grab and go without much afterthought, so more opportunities to shoot.

Besides, I don't think anyone is pixel peeping for sharpness or how much CA are in our collectively defining photographs. Heck, likely don't even know which camera/lens was used that took the photos.

A Canon RF 300-600mm f/4-5.6L IS USM on the Horizon

Thanks for the heads-up;). Enjoy your new lens. You can buy 2 or 3 200-800mm lenses for the rumored price of the 300-600mm.
Honestly I'm willing to pay $6-7k for this lens if it's anything like the amazing 70-200Z. The latter is incredible even with the 2x teleconverter, but I do need some more length that isn't a $14k 600mm f/4.0 lens lol. Going up to 600mm @ f/5.6, presumably with a bit better IQ than the 70-200Z @ 400mm (also f/5.6) would be lovely. Plus having up to 840mm with a 1.4x would be attractive for some situations.

Would really prefer to avoid the slow external zoom like the 200-800 as well. The internal zoom on the 70-200Z is fast and feels perfect imo. Helps when getting zippy subjects like this:

Show your Bird Portraits

View attachment 226834
I thought it was a crow, but there seem to be some brown around the neck. Unfortunately I wasn't expecting to see any birds I'd want to photograph so this is 16mm. I tried to get lower to avoid the vertical perspective distortion but spooked the bird.
If it's a question it would be nice to shear were you took the photo. The picture by itself is not telling a lot!

Why I’m Buying The R5C Instead Of The C50 (Or R6 Mark III)

You mentioned the "portability" of the C50 and how it's better for gimbal use, but then forget that the top handle has to mount on it to get XLR inputs and now it's not as easily mounted on a gimbal. I agree with you though that the R5C is still the best hybrid out there. The C50 could have come close if it would trigger a flash.
