nah very good thermal ratings under normal conditions. non issue. if you're shooting in very hot environments though the fan exists..

If you're a DP/Camera op bringing in enough monthly to more than justify the cost of a modern high-end production camera then cool. But it seems the general consensus is that the diminishing returns of camera bodies has most smaller production companies and freelancers own their lower-value base kit (your Komodos, R5c, lumix cams, sony alpha cams etc) and rent the higher end models of the same system for the demanding projects that warrant them. I invested in Topaz too, and am a believer in the concept of older cameras being good enough. But, how often are you going to add AI upscaling as a viable process to your workflow/pipeline? It helps in a pinch when you want your C-cam Blackmagic Micro to match your big boy units for a couple shots, but upscaling doesn't sound fun to do all the time. Unless you are only upresing the final render, it doesn't sound efficient adding possible hours of overnight upscaling your clips in your home render farm.

Given that (as far as I can see) onsemi's image sensor capability mostly comes from buying the image sensor division of Cypress Semiconductor in 2011 for $31 million (based in Belgium) and US-based Aptina in 2014 for $400 million, I think there is a reasonable chance that the Arri sensor was developed in US. As a bit of trivia, onsemi's roots as a semiconductor manufacturer go directly back to Motorola in the 1950s, so it's effectively one of the oldest chip companies in the world. (ON Semiconductor was spun out of Motorola as in independent business in 1999).

Canon, Nikon, Leica and Blackmagic are more than just camera companies - they have other business lines. Of those, Canon and Nikon are probably the most exposed to market changes, due to their historically large presence in the consumer market. Leica, Arri, Red, Blackmagic & Hasselblad are niche players in the overall camera market. I think OMDS has a difficult transition to make into probably a somewhat smaller and more niche player. They do have the audio recorder side of the business as well, but doubtless some of that market has been lost to mobile phones.

That's exactly what's kept me in the M43 eco-system. One of my interests is wildlife photography & video, and the Oly 75-300mm is only around 420g and 120mm long. Combine that with the ex-tele sensor crop capability and IBIS on a Pana G9 and you get the FF equivalent of 1000mm+ lens reach in a combo that fits easily in a modest camera bag or small rucksack (and the oversampled( GH5-level) 1080p on that is so good it's quite close to 4k quality). Take along the 210g Pana 12-60mm lens and that's basically 12mm to 300mm covered in two decent-quality zoom lenses that weigh less than 650g in total.
