Looking ahead to 2024, we anticipate that Canon will continue this trend and focus on developing lenses that have been highly requested by shooters. Two previously rumoured lenses have appeared in recent patent applications and would surely be extremely popular. Canon RF

Weird little quirk I noticed about the zoom lock switch on the RF 24-70 2.8

This is completely inconsequential, but discussing pointless things is what forums are for, so here goes.

I finally broke down and bought the RF 24-70 2.8. In playing around with the lens, I noticed that the zoom lock switch doesn't only lock it at the widest angle where the lens barrel is full retracted. There's another spot where the lock switch is able to click into its locked position. In addition to 24mm, it also locks at the 31mm focal length, according to the lens data when you take a photo with it locked at this spot.

This is clearly unintentional, considering that 31mm is just a weird focal length. The switch sounds just a little different when it clicks into place at 31mm compared to 24mm as well. What makes it even more curious is that the manual specifically states "The zoom ring cannot be fixed in place at any position other than the widest position." Except that, you know, it can. :unsure:

So anyway there you know, strange quirk about the RF 24-70. Completely useless to know and to use. I wonder what causes it though.

Cheeky Yongnuo introducing YN85mm F1.8R DF DSM II

For anyone looking for 3rd party RF lenses with AF. The glimpse of hope is down to Yongnuo again.

Earlier on this year they re-introduce the YN85mm F1.8R DF DSM onto their official website and Taobao(the domestic version of Aliexpress, and it's much better than Aliexpress but PRC only due to the payment methods). They named to mount as 多規格(Multi-spec) to get away from Canon China's legal action.

And now they introduce the mark ii with movable electrical contact points to evading Canon's legal team further... And other manufactures should consider this as Canon didn't patent the RF design in this way:ROFLMAO:

Sadly, the pricing outside of China is ridiculous, it's not competitive enough to get them instead of Canon's. Unless you have someone know how to buy it directly from Taobao or Yongnuo's official site.
And my personal advice is for RF users that doesn't have IBIS. it's not worth it to get it over native options.

Myself has the original batch of YN85 and YN35.

YN85 is perfect, no issue with the lens' performance and firmware updates.

YN35 is somewhat a letdown as the Servo AF with subject recognition on is not reliable enough. When using Human/Animal/vehicle recognition but no such subject in frame. It won't go back to normal servo AF and focus hunt everywhere across the frame. And the AF area is smaller(but bigger than f11 Duos). Forcing myself to switch it off or use Single shot AF only. No issues on video AF though.

Enough rant from myside. Praying Viltrox and other CN 3rd parties to do the same on the lens mount, so those APS-C primes can be available for RF-S as well. (16/50mm f1.8, 23/27/33/56/75mm)

btw Meike 85mm f1.4 RF when???? Was that just fake news?

Sony Will Let You Add Custom Gridlines to Your a7 IV for $150

Hearing the calls from desperate photographers asking for meaningful firmware updates, Sony has obliged with the option for Sony a7 IV users to add up to four custom gridlines to their cameras for a $150 fee.

The “Custom Gridline License” allows a7 IV users to import up to four custom, original gridlines into the camera that can be displayed on the electronic viewfinder or the rear LCD for what Sony says allows for the creation of more consistent photos.

“For example, staff at schools, photo studios, theme parks, cruise ships, malls, etc. will now have the ability to update their cameras with ease and utilize this tool for quick and precise, more professional shots,” the company says.

“Imported customized gridlines are replaceable and color gridlines are available. Once gridlines are registered, it can be displayed with HDMI output as well. After shooting, users can check the images with the grid lines overlayed on EVF and LCD.”

While that is the primary purpose, Sony says that not only can these be used as gridlines but they can also be used as partially filled transparency masks.

Sony’s upgrade has received the backing of multiple organizations in its press release, including Inter-State Studio and Publishing, Strawbridge Studios, Inc., the School Photographers of America (SPOA), and the School Photographers Association of California (SPAC). The target, obviously, is squarely what is often described as “turn and burn” photo jobs that are high volumes of consistent portraits.

“The ability to import customized gridlines into a mirrorless camera is an essential feature for all of our photographers to capture images consistently,” says Frank Lombardo, National Photography Manager for Inter-State Studio and Publishing, for example. “These simple gridlines keep head sizes the same for all our products and improve our production time. They also allow us to know where the edge of print will be during capture.”

It should be noted that this one function is the entirety of the $150 license. For context, Panasonic’s optional S1 filmmaker upgrade costs the same and that adds 4K 60p 4:2:2 10-bit HDMI live output, 4K 30p/24p 4:2:2 10-bit in-camera recording, LUT support, and V-log.

The Sony a7 IV gridlines license will be available for $149 directly from Sony’s Upgrade and License Management Suite starting in Spring of 2024. Sony says it will add the upgrade option to more cameras “in the future.”
Seems like a lot of money to charge for some grid lines.

Voigtlander 50mm f1 Nokton RF Review

Gordon from CameraLabs has done a great review of the Voigtlander 50mm F1.0 Nokton RF. Yes, that’s an F-One-Point-Zero. Of course, the only reason it’s allowed on our precious RF mount legally is that it’s manual focus, so, at F1.0, that’s going to provide some challenges. But if you grew up with manual focus lenses
