My case: when (I could go back to) travelling, generally use one cam to shoot stills and video. And, for video, frequently want to put it fast in a small gimbal, take the shot, and remove it again to come back to stills.

Of course, this means having a quick release in the gimbal and a plate in the camera. Long ago I settled with Arca plates - currently, besides some generic plates and clamps for tripod work, In trips I use a Peak Design Standart Plate (https://www.peakdesign.com/collections/clips/products/standard-plate-v3) on the camera: small and still compatible with Arca (kind of, no secure pins for example).

In my gimbal, in the last trip, used a very small arca clamp, like this one (https://www.amazon.com/Neewer-Release-Compatible-Arca-Swiss-Included/dp/B07NB2RSFZ/ref=sr_1_27?dchild=1&keywords=small+arca+clamp&qid=1632921831&sr=8-27). It worked, but putting the camera on the gimbal involved: - Putting the camera on the clamp; - Align precisely the camera in the clamp in a previously balanced position; - Tight the clamp knob; - Take the shot; - Untight the clamp knob; - Remove the camera.

Once I had a drop-in clamp for a Manfrotto-ish plate in a tripod that would work much better: just drop the camera in the clamp, the plate have the same format as the clamp chamber (no alignment needed), lock fast with a lever, and to remove just open it with the lever and take the camera out. But in my last trip, did not found anything like it for Arca.

Today I've saw that Pgytech released a solution that is exactly that: https://www.pgytech.com/products/snaplock-plate-adapter . A small Arca plate (that looks like very similar to the PD one), and a autolock plate. Just drop the camera in there (with the quick release on the gimbal), take the shot, press the button and remove.

And that Ulanzi have a system that solves the other part of the question - removing the camera from the neck strap (where I have the camera for stills) to put it on the gimbal - https://www.ulanzi.com/collections/quick-release-system/products/falcam-f38-quick-release-camera-strap-clip. Put this on the neck strap, press to remove the camera from the clip, put it on the gimbal, take the shot, return the camera to this one, move one.

Just one caveat - the plates from both systems looks like that have the same dimensions, BUT maybe they are not compatible (the plates for both do not fit in Peak Design clips, for example).

The Pgytech have the gimbal solution, Ulanzi have the strap solution, but don't know if their plates are compatible. Anyone used any of these sytems, or know some similar system? (the most important solution for me is the gimbal part, have to be like the Pgytech clamp).

Building on last year’s successful launch of the Element MII collection, which stands for MADE IN ITALY, the arrival of the new ELEMENT MII Fluid Video Monopod completes the range.

The go-to product for hobbyist and traveller videographers, this ultra-portable fluid monopod, is ideal for shooting weddings, corporate videos, interviews and documentaries and all those dynamic situations where agility and precision really count.

Compact, lightweight and brilliantly smooth, it combines sophisticated performance with simplicity of use. It’s quick and easy to both fold down and pack away and works perfectly for CSC and DSLR cameras.

The ELEMENT MII Video Monopod is the first in the Manfrotto range to incorporate the new high-performing, ergonomic twist locks. These make set-up and adjustment much easier and more comfortable, while also offering maximum grip, quick leg opening and extreme compactness. The locking mechanism ensures immediate setting, while the multiple sections (four in total) give optimum compactness and height.

The new Video Monopod also has an incredibly smooth panning action, thanks to the patented, lightweight fluid cartridge in the base. Leveraging the judder-free base sphere, tilt position can be reached on the most uneven surfaces, allowing users to take advantage of pan fluidity in all sorts of conditions.

To meet the differing needs of amateur videographers, the Element MII Fluid Video Monopod comes stand-alone or as a kit. The stand-alone version presents a lightweight aluminium body. Apart from making this an easy-to-carry product, this durable aluminium design means it can stay totally rigid when the sections are fully open while being able to support loads up to 16Kg. The kit differs slightly. It incorporates a non-detachable compact fluid video head which, thanks to the Manfrotto Fluid Drag System, gives ultra-smooth and flawless tilting. It is supremely light and stable, being able to support up to 4Kg.

ELEMENT MII Video Monopod Kit has been engineered to deliver maximum portability, with a removable, collapsible pan bar and fully foldable, extra-lightweight head and base feet. The entire kit weighs just 1Kg and folds to a compact length of 60cm. Able to be collapsed, packed away in no time and carried anywhere with ease, this kit truly offers best-in-class stability that’s perfect for on the go.

Manfrotto is the world leader in photography, videography, imaging equipment and accessories. Like all Manfrotto products, the Element MII Fluid Video Monopod is made to the highest quality and design standards. Aside from its wealth of high-performing features, the beautiful aesthetics and striking red leg graphics put it in a class apart.

The tripod is provided with a 2 in 1 half ball: a standard 100mm bowl along with a 75mm adapter to enable the use of a wider range of video heads. It also features a middle spreader lock. However, the 3-angle selectors make the use of a spreader a matter of optional preference. Users will also enjoy the extremely low maintenance this product requires.

635 FST Single-Leg Fast has single tubing and features the Extra M-Lock twist lock, for secure locking with a single, easy gesture. The 635 FST tripod features a 75mm half ball and is compatible with a 60-mm half ball adapter (sold separately). In addition, it features Easy Link friction arm attachments compatible with Manfrotto anti-rotation and Arri anti-twist pins. This enables users to attach an external monitor or any other accessory they may require without the risk of the arm rotating while in use.

Shoot videos with enhanced audio and visual quality, with two new accessories from Canon 

Harness your creativity and capture movies and stills in new dynamic ways using the Canon Tripod Grip HG-100TBR and record crystal clear audio with the Canon Stereo Microphone DM-E100

Canon Europe announces the addition of two ergonomic, lightweight and versatile accessories, the Canon Tripod Grip HG-100TBR and the Canon Stereo Microphone DM-E100. These small and affordable accessories will provide vloggers and videographers with higher quality audio and video content whilst also granting greater creative versatility when filming. 

The Canon HG-100TBR is Canon's first tripod grip to feature wireless operation, thanks to the integrated Canon Bluetooth Remote Control BR-E1, making it the perfect vlogging accessory to shoot stunning video footage in a variety of styles, even from a distance. The Canon DM-E100 stereo microphone has an ultra-compact design and is Canon's lightest microphone to date in the accessory range. It enables vloggers and videographers to use it alongside the more compact cameras in the Canon line-up, such as the PowerShot G7 X Mark III, and improve the quality of their audio soundtrack whilst on the move.

Film with confidence with the Canon Tripod Grip HG-100TBR

The Canon HG-100TBR is a unique tripod grip that enables consumers to capture stable footage and film at a range of angles in a much more creative way. When mounted, the tripod grip enables the camera to rotate 360° left or right which can be locked in position, enabling easy recording whilst talking to the camera, or shooting at creative angles. Aspiring vloggers can also make use of the adjustable camera mount, which enables the camera to tilt forward 45° and back 90°, making it easier to capture quality video content from high and low angles and even in selfie mode. Furthermore, the tilting tripod head supports vertical movie recording when using with a camera that allows vertical movie shooting¹, making it well suited to those looking to capture content and share on social media.

The ergonomic, lightweight design of the tripod grip makes shooting quality video over long period of time much more comfortable. The grip can also be set up as a tripod, enabling landscapes and group shots to be captured with ease. It can be easily folded up to fit in a camera bag, making it the perfect companion for vloggers shooting content whilst on the go.  The included Canon BR-E1 can be operated by the same hand when the product is used as a grip, and as a remote, when set up as a tripod, making it much simpler to start, stop and re-start recording footage.  

When used with the bundled Canon BR-E1 wireless remote control, the Canon HG-100TBR tripod grip enables easy remote shooting, giving consumers control of the camera's shutter, zoom2, movie recording and AF from a distance. The tripod grip enables PowerShot camera owners to use the optical zoom remotely, to spontaneously shoot close-ups. 

Enhance sound quality with the Canon Stereo Microphone DM-E100

Videographers can now take their movies to a new level with ease thanks to the Canon DM-E100. A small and practical stereo microphone, which offers enhanced sound pick up and low noise to capture clear audio content. The Canon DM-E100 stereo microphone has an electret condenser design and boasts 120º unidirectional stereo sounds down to -40dB sensitivity, providing better perspective and a more realistic sound when recording videos. Complete with a 66 dB S/N (signal/noise) ratio, 100Hz to 10kHz sound frequency pick up and a wind screen to protect it from outdoor background sounds, the microphone enables users to capture a clear, wide sound scape with reduced noise. 

This microphone is a great addition to any budding YouTuber's kit, ideal for recording 'how-to' tutorials, conducting product reviews and hosting interviews. With plug and play functionality, the microphone does not require a battery to work so users can capture high quality audio the moment they turn their camera on, simply by connecting the microphone with the built in 3.5mm audio jack3.  Weighing just 64g and no bigger than the palm of your hand, the Canon DM-E100 stereo microphone barely adds any extra weight to your camera and can slip easily into a pocket or camera bag.
