3 Plus DSLR Wireless Camera Remote Controller, WiFi and 4G High Speed Capture and Transmit Aperture, Shutter, ISO, Live View,Focus Stacking, Support CP1 LR

I bought this product as an alternative to the more superior CamRanger 2. I have been using the Camranger and more recently the Camranger 2 and have been happy with it. Unfortunately, I encountered an issue with my Canon EOS R7 wherein there are occasions when the Camranger 2 suddenly crashes when using them together. The Camranger team has been very responsive but has still been unable to figure out the problem. My other cameras all work well with the Camranger 2, but I needed to find an alternative to use with the EOS R7. So, that's why I bought this CamFi 3 Plus.I bought it because it had similar features as the CamRanger and precisely because it said it works with the Canon R series cameras and works with RAW files. I checked the list of compatible cameras and my canon cameras are listed. But when I started to use the Camfi 3 Plus, it does not support CR3 files, which are the RAW files of the Canon R series cameras. I tried using the Camfi with their app connected to different devices, but it still did says it does not support CR3 format. So, big fail.So, I tried reaching out to them repeatedly but they have never replied. I waited weeks and tried again but still no reply, no support. So, I would not recommend this if you are using the Canon R series cameras and shoot only in RAW format.I also was disappointed that it's not consistent with the display speed even with JPEG. Sometimes it takes two to three seconds, but sometimes its several seconds.
