Not all that glitters is gold or is it? Have you taken any pictures with the S1 camera yet? How good are they? How is the AF? What is keeper rate? How responsive is the camera (e.g. start-up, LCD, EVF, joystick, and card read or write? How good are the SOOC jpegs? etc.
Convincing anyone to listen and buy this camera based on hearsay is like barking up the wrong tree.
Could you please post some sample images taken with your S1 (when/if you have it).
You can find reviews on YouTube and online articles. I don't post my photos since it's mostly clients work and personal landscape photo. I do not want to get doxxed since I have a professional career outside of photography. I do photography only as a side gig.
The camera is very responsive. It reminds me of Canon camera in many ways - fully touch screen LCD, intuitive menu, ergonomic is superb, EVF is best I've used including EOS R/A7III/A9/A7RIII. The SOOC jpeg look good. I always shoot raw so I do not rely on the JPG. Even with Canon 5D IV/EOS R, I never hand over any SOOC to clients or publish SOOC works.
I really like the backlit buttons and plenty of buttons options. The front switch for electronic shutter is a nice option. The rear dial that quickly switch from AF-C, AF-C, Manual is very nice to have to allow quick change. The dial to change mode setting is also very nice. The entire menu can be fully customized and save to SD card. That's really nice to have as backup. Beside it's being as big as 5D IV and weight and the odd power button placement, the ergonomic is very nice.
I'm currently only UHS-I and it kept up with 9 fps. I do not rely on 7 fps with my 5D IV or EOS R so 9 fps is plenty for me. I will buy CFExpress card when it's available this summer.
The keeper rate is alot higher than my 5D IV. It track the eye much better than the EOS R I had a couple months ago. It still doesn't beat Sony A7III but it's good enough for me.
I'm not convincing anyone to buy this. I don't get commission, have affiliate link, YouTube views etc. If you buy it great, if you don't, that's fine.
After the battery and battery grip, I see it more like a $2000 camera purchase for me that's fully specs. I still have yet to try it on paid works and try the Sigma MC-21 adapter. Once I determine it's suitable for my works, my Canon 5D IV will be up for sale since I see FF mirror less as the future.
This isn't going to be my last camera purchase. If Canon, Sony, Panasonic has a competitive camera that has good blend of camera usability and features, I'll get one. I really hope Canon offer competitive features and price in their EOS R Pro line (5.76 million dot EVF, IBIS, new sensor, dual card slot, better eyeAF) that's similar price to the competitions.
