off-camera flash: what makes / models (non-OEM) of speed lights are compatible with the Canon 600EX-RT 2.4GHz * radio signal (non-optical) *?

Many "generic" flash manufacturers have units that are course to be compatible with Canon RT radio system. Most of them include "RT" in the model number of the units they offer that they claim to be compatible. Most of them are, for the most part, compatible with Canon OEM RT devices. When it gets a little messy is when you try to get two different generic "RT" flashes from different manufacturers to work together. It is then that problems seem to begin to arise more frequently.

Yongnuo is probably the best-known brand that makes generic RT flashes. Not all of their flashes use the RT protocol. In fact, most of their flashes don't. But those that have an "RT" in the model number, like the YN600EX-RT II. At the Yongnuo naming convention, the EX means that the flash supports TTL. RT means it uses the Canon RT radio protocol. Most Yongnuo TTL flashes are also capable of HSS, second curtain sync, multiple flash, etc.

If all you are going to use are flashes, then RT is not a bad way to go. But if you ever want to mix fast lights with more powerful monolights, be they battery-powered laptops or network-powered studio lights, you're limited to being able to tell those flashes to "fire" by plugging an RT receiver unit into the trigger port with monolight cable. To change the power or other settings, you must do it directly on the flash control panel. It is also almost certainly limited to manual power control without HSS, E-TTL, second curtain sync, etc.

There is another wireless system that offers compatibility with lights in its line from compact low power manual flashes with guide numbers of less than 40 meters to very powerful studio lights that produce more than 1,000 watt-seconds. This is Godox, which is also sold under various trade names. Adorama in the United States, for example, sells Godox products under its private brand & # 39; Flashpoint & # 39 ;. There are also vendors in Europe that sell Godox products using a private label.

Using a TTL compatible receiver with the Godox system allows one to have remote power control, use HSS, etc. as long as the flash is capable of doing the same directly connected to the camera's hot shoe.

That's something to think about before getting too deep into a flash-only radio protocol.

Canon – Phottix Ares flash trigger does not fire

I have a Canon 7Dii, Canon 430EXii and a Phottix Ares trigger.
The camera-mounted flash fires hot shoe and when mounted on a soft box mount, the pilot button fires the flash.
As soon as I try to use the remote trigger, the system fails. The batteries are fine, with the flashing yellow flashing light on the triggers and they are both set to the same channel, but when I press the test button nothing happens. It will also not fire on the shutter button.
I've had it working in the past, so I think this is a configuration issue, either on the camera or the flash, but after reading all the manuals I don't know what's wrong.
Any help would be highly appreciated.

Canon: remove focus rectangle on M6 Mark II during clean HDMI output to Elgato Cam Link with autofocus enabled?

I have a Canon M6 Mark II camera, and recently bought an Elgato Cam Link so I can use it as a very high quality webcam during social distancing. I made it run pretty fast, however even with a "clean" HDMI output it still shows the auto focus rectangle regardless of the focus setting. I would prefer autofocus, but I can live with manual focus, but even when it's set to MF it still shows the rectangle.

I have tried the following (with result):

  • Change physical body change from AF to MF (remove AF rectangle from live view, but still appear on my PC)
  • Turn Movie Servo AF off in menu options (dim the AF rectangle in live view and Servo AF icon is not displayed)
  • Temporarily disable Movie Servo AF in live view (same as disable in menu except icon is still there)
  • The same as above but in FHD instead of 4K (no difference)

This is frustrating since nothing to show the AF rectangle is "clean" IMO. This use was not anticipated before buying the camera, since I have only made still images, I have not used any type of video before. If relevant, I am using the Canon 22mm EF-M lens.

I've seen a variety of recommendations online for cameras in the same family (M50, M100, M6 I) and not many specifically regarding the M6 ​​II. Either they claim that you can't remove the box, or switching to MF will remove it, neither of which seems to be the case unless there is some way to switch to MF that you haven't tried yet.

This is not very important to me, but I wanted to ask in case there really is a solution and for a clearer SEO than the group of outdated camera forums that I searched for trying to find a solution earlier.

How to tighten the loose focus ring on Canon lens?

I have an EF 24-105mm f / 4 L IS that is 'well broken' with a very loose zoom ring. When the camera is pointed down, as it is when hanging on a strap or neck strap, the front of the lens fully drags to the fully extended 105mm position.

I use a plastic bracelet stretched around the lens body with part of the width of the bracelet on the zoom ring and part of the width on the stationary part of the lens body. The band provides enough resistance to prevent the zoom from dragging due to gravity. The amount of the band in the zoom ring and the amount in the barrel determines how much resistance is added.

The same type of band can be used to give a focus ring more resistance. There is even a company that markets such bands specifically for camera lenses, but I have never tried them because they appear to be the same as the rubber bands I already have for me.

enter the image description here

The TS-E 24mm f / 3.5L is a slightly smaller diameter (approximately 78mm) in the focus ring than the barrel of my EF 24-105mm f / 4L IS (approximately 83.5mm). The TS-E 24mm f / 3.5 L II has a slightly larger diameter (approximately 88.5mm) than my EF 24-105mm f / 4L IS. I would hope that you could easily find a generic plastic / rubber bracelet of the type used to promote charities and companies that cater to any one of them.

From a comment by the OP to another answer:

I bought this lens a few months ago (new). I think it is, but I find it strange that it is so loose by design.

The focus ring of all Canon TS-E lenses that I have handled is fairly well damped without being stiff. If the lens is under warranty, I would not hesitate to contact Canon Service. If you send it to them and they tell you there is nothing wrong, at worst it is out of the shipping price.

Photos.app does not combine some Canon 60D CR2 (RAW) + JPG flies

When importing RAW + JPG images from my Canon 60D to Apple Photos on macOS 10.15, some are merged, most are separated. How can I fix all this? I imported about 300 images before this started happening. I tried using HoudahGeo to change the times, hoping this could make a difference, because I took the photos in 6 different time zones and forgot to change the camera time at some points.

raw – Canon DPP 4 – copy / apply white balance settings

I have two shots taken with automatic white balance setting (AWB) in artificial light conditions. I like how the camera evaluated the white balance in the image with the white leg, I like how the green color looks, etc.

enter the image description here

The second image looks reddish. I tried moving the 7-point microp slider towards green, but I don't like it as much as the first image with the default settings.

enter the image description here

I need to know how to copy the white balance settings and apply it to another file. I found the only possibility to register the "click white balance" profile. If DPP 4 can't, is there any third party software that can do this?

sony a7ii vs canon t7i

I am divided between a new A7ii full frame or a Canon T7i. I currently shoot on a rebellious digital canon and have a glass kit that I can use if I buy the T7i. I shoot many landscapes, wildlife, scenic photos. I heard that the full frame is better for photographing the Milky Way that I would like to try.

Can I get a Sony A7ii for $ 935 with the 28-70mm lens kit
I can get the T7i without a lens for $ 550

Which one would you buy

Canon: Can't change the aperture of my 77D

I am trying to change the opening mode with the gear shown in orange:
r

while shooting in manual "M" mode.

The lock switch is not active (below).

I can change the shutter speed with the top gear, but I can't change the opening more than the forward gear.
I can only change the aperture from the LCD screen.

Is it physically possible to mount a manual EF-M lens to a Canon DSLR without an adapter?

No. They are physically different frames, with different dimensions, shapes and sizes. EF-S lens on the left; EF-M lens on the right.

If the lens fits the EF-M mount, it will not fit the EF-S without some form of physical link adaptation. But even if there was such an adapter, it would never reach full focus range to infinity with one, because the depth of the mounts is also different.

The EF / EF-S mount is 44mm deep; EF-M is 18mm. Therefore, any EF-M lens would be sitting 26mm further from the sensor than it is designed to sit on. This would be like using a macro extension tube and would restrict the ability of the lens to focus on the far end. And that distance is probably too big to make up for with a teleconverter element on any adapter.
